Welcome to my pump blog! Here is the professional blog about all kind of pump technical articles, such as water pump, centrifugal pump, pressure pump, gas pump and so on.What's more, we supply you funny pump products and uses.

The perfect complement to any landscaping project or garden is a beautiful water feature. You just have to make sure you choose the correct water pump to create the effect that you desire. There is a wide choice of pumps available that make water run, spill, bubble and shoot water into the air. They also help to aerate the water and protect your pond from becoming stagnant.

One of the most important things to think about when choosing a pump for your water feature, is how much water you need to move to make it operate correctly. First you need to decide what kind or effect you’re looking for. Most water pumps will come with a variety of nozzles to choose from, allowing you to change the fountain effect. They are also available in one, two or three tier models. If you choose a two or three tier design, you will need to make sure to get a pump that moves enough water to create the effect you want. If you choose to go with a waterfall or some similar design, the stronger the pump will need to be. A good rule to remember is always get a pump that can move more water than is necessary to create your feature. Additional capacity will also help you make adjustments later on if you choose to change your design.

Another factor in choosing water pumps is how much noise they make. If your water feature is in close proximity to your outdoor entertaining areas, you’ll want to look for a quieter pump. Most pumps today are fully submersible allowing for quieter operation.

For waterfall operation you will first need to determine the height above the pond surface from which the water will flow and the capacity of the body of water supplying the water. This will help you determine the gallons per hour your pump will need to circulate to properly and efficiently operate your waterfall. There are tables and charts you can find online to help you determine which pump has the proper GPH output for the dimensions of your waterfall.

Another consideration is how close an available power supply is. If you had planned your water feature when designing your landscaping, chances are you installed electrical outlets within range of your pump or waterfall. If there is no electricity within close range and your feature is in direct sunlight, a solar powered water pump is your best option, and costs nothing to operate.

Maintaining a garden pond or a bigger aquatic pond for commercial purposes requires proper water circulation. This is why you need to invest in a highly reliable pump, whether you have one at home or in a bigger location, like a farm. It is responsible for the oxygen in the water and in contributing to the biofilter of the pond, which is necessary in purifying or cleaning the water. Due to their versatility and ability to handle suspension excellently, centrifugal pumps are a popular choice for many pond operators or fish farm owners. Other types include diaphragm, roller, and piston pumps.

Pump buying considerations

When it comes to buying pumps for your fish pond, you will need to factor in the flow rate and water head or pressure produced by the pump. The flow rate is also known as the output, often determined in liters or gallons. Make sure that you choose one that is a good fit for the size of your pond. A bigger pond will require a more powerful pump, but installing a powerful pump in a small pond often causes problems. A flow rate that is too powerful may stir up sand in the pond, resulting in murkier waters.

The ability of the pump to spurt water at a specific height is known as its water head or water pressure. Prior to buying one, it will be helpful for you to at least estimate how much water head your application will need. This way, you’ll be able to get the best type of pump to match your project. Most fountains and waterfalls require pumps with higher water head.

The advantages of centrifugal pumps

Centrifugal pumps are popular for several reasons. These are versatile and come in many different types. These include standard centrifugal, high pressure, and trash centrifugal pumps. Centrifugal pumps are also high capacity pumps and don’t require as much maintenance as other kinds of pumps. There are also designs of centrifugal pumps which are meant to handle solids, which are recommended for washing down equipment.

The Pentair Water - Flotec - Simer Centrifugal Pump is built for general purpose pumping, whether for ponds, fountains, waterfalls, or pressure sprinkling. This pump comes with rugged cast iron housing, making it perfect for heavy duty use. Buying a versatile and easy-to-use pump is excellent for a wide range of water gardening or clear water applications. With a ready to install pump, you’ll have your pond in stable working condition within minutes.

Water pumps are used mainly to move water for a variety of purposes. From applications requiring standard water flow or movement to applications that need high pressure pumping, water pumps are used across different industries and even at home. A wide range of contractor pumps nowadays work through centrifugal force and are known as centrifugal water pumps. These may be used for a range of applications requiring water transfer and water movement, including garden waterfalls, fountains, and sprinkling.

Types of centrifugal pumps

A centrifugal pump works through an impeller and volute in order to produce the vacuum and pressure needed for water movement. Both the impeller and volute influence the flow of water, as well as its pressure and handling.

These come in different designs, which in turn produce different discharge rates and water pressure. Standard ones are used for different water applications, whether for home or agricultural use. These are also used in different industries. Although these pumps do have limited capabilities when it comes to handling, they are an economical choice for many users. For higher pressure and flow, high pressure centrifugal pumps - with a capacity of producing 100 GPM - are more ideal. These are useful in washing equipment, fire control, and irrigation.

The last type or design is the trash centrifugal pump. Don’t be misled by the name - it’s merely referring to what goes down the pump! With the ability to wash down large amounts of waste, these types of pumps are used widely by many contractors. Trash pumps are usually priced higher than standard centrifugal pumps due to its higher horsepower requirement.

How to choose a good pump

When it comes to choosing a pump, you should consider first of all the volume and pressure requirements of the application as well as the material being pumped. Along with clear water, oil, fertilizer and other chemicals may also be pumped. You will also need to check for horsepower requirements especially in terms of discharge pressure and volume. Centrifugal are known to handle suspension excellently and don’t require high maintenance.

The Pentair Water - Flotec - Simer General Purpose Centrifugal Pump can be used for a variety of water transfer and water circulation purposes, whether for gardens, ponds, or other clear water applications. By using a centrifugal built for versatile purposes, you are assured of successful water transfer and water movement results, for a wide range of residential, agricultural, or industrial applications.

One of the most important steps in maintaining a swimming pool is to ensure a properly working filter and pump system. The pump is responsible in circulating water in the pool and in evenly distributing chlorine or other cleaning chemicals all over the pool. The filter keeps debris from entering the pump so that the pump system continues to run smoothly. Without a properly working filter and pump system it will be impossible to keep your swimming pool clean.

How do pool pumps work?

Pool pumps work through a small-sized motor which powers up the entire unit. The motor of the pump creates suction and propels the water down along the main drain of the pool. The main drain leads to several pipes, which eventually leads to the filter. As the water passes through the filter, leaving debris and particles behind, it is guided back into the pool through a jet located underwater.

How do I choose one for my pool?

There are many types of pumps available for swimming pools, all with different flow rates and water head rates or resistance to flow. To choose a pump that is a good fit for your swimming pool, you will need to take into account the recirculation system of your pool first of all, so you will know whether you need a powerful pump or a smaller one. This will give you an idea as to your desired flow rate, often determined in GPM or Gallons per Minute. The minimum flow rate in GPM allows the pump to move the water from the pool into the filter within a specific time. Not only do you need to determine how much water needs to be moved or circulated. You also need to consider on how fast the water needs to be moved and how much resistance the flow is up against.

Maintenance

To maintain your pool pump, regular cleaning is necessary. Weekly cleaning is advised as debris and other particles can build up over the course of a week within the filter. A blocked filter will lead to a poorly functioning pump system, which is something you don’t want if you plan on keeping a well-maintained pool.

A durable and well-built pump, like the Wayne Water Systems 1-1/2 HP Pool Pump, is an excellent choice for standard residential swimming pools. It is a self-priming pump fitted with thermoplastic parts which resist temperature changes and corrosion. With proper maintenance, especially on a weekly basis, you can expect your pump to work consistently, keeping your pool well-aerated and clean.

In the world of high pressure pumps, there is a great variety. High pressure pumps are used on a daily basis in all kinds of different industries. They are used in the residential community and commercially and are also used in many different other industries, such as waste management just to name one. These pumps make jobs possible that would otherwise be impossible to do with mere human hands. They work great for many different applications. However, you need to pick the right one to get the best results.

One popular pump is called the centrifugal pump, and it’s used to carry liquid through a pipe way for water treatment, food, chemicals and so on. When the liquid meets the pump, it goes onto something called an impeller which slings the liquid away, which changes the liquid’s direction, therefore increasing the pressure. These pumps consistently move the liquids for moving, loading and elevating fluids. Centrifugal pumps are very handy in so many industries, and can be utilized for waste management, ships, food industries, and many more.

Another type of pump is called the container pump, and it’s special in the way that it is specially designed to move dangerous liquids in and out of areas, even highly flammable or toxic ones. These pumps are very thorough and are great for several industries, even the cosmetic to give you an idea of one in particular. Container pumps are almost always made of high quality stainless steel and are very well tested to withstand years of use, these pumps are sturdy and long lasting. Another great thing about the container pump is that it is easily cleaned and easy to take care of, especially compared to some other types of high pressure pumps.

The drum pump is used often, as it’s very versatile and can be used for processing chemicals, perfumes, cosmetics, and even the in food industry. With drum pumps, you rarely lose any high-quality liquid, so it’s great for top notch fluids that can’t be wasted. The drum pump is known for performing very well even in high stress applications. This is one pump that can be made of either stainless steel, polypropylene or even an aluminum alloy. As with the container pump, the drum pump can also be used for highly flammable fluids as well.

Other than these three high pressure pumps, there are many others out there. As you can see, some have lots of differences and some may seem to be almost identical. This is why it’s so important to research each and every one and figure out which one is the best for your needs. Not all pumps are the same, even when they may at first glance seem to be.

Ontario Beach seaweed is always a headache the other swimmers, and now the government has come up with a good way to use the pump to clear the algae

Algae, the bane of swimmers at local Lake Ontario beaches, were thick enough that the area was closed to swimming for the day.

But for a small crew of workers who gathered at the beach’s east end, the algae were almost a welcome sight — for it provided one last chance to test a system to pump algae-laden water away from the beach.

The monthlong test, conducted by the U.S. Army Corps of Engineers and Monroe County, was intended to see whether algae could be removed from near-shore waters, thus minimizing the chances that the foul-smelling aquatic growth would force closure of the beach.
The system uses a portable pump to suck water from the east end of the beach and deposit it in the nearby Genesee River, which carries it out into Lake Ontario.

The general assessment was that the system, funded with $230,000 from the corps, worked well at removing algae that otherwise would have festered on the beach, possibly prompting closures or aesthetic complaints.

“We’re very happy with the results. I think we have shown that it can work,” said Bryan Hinterberger, project manager for the Army Corps in Buffalo.

That was before the final challenge on Wednesday, the day the test was scheduled to end. Overnight Tuesday, a wind shift had allowed copious amounts of algae to drift toward the sandy beach, creating a larger and more spread-out algal assault than others during the test.

So the pump, connected to an intake attached to the end of a long-armed excavator, was fired up. A front-loader motored back and forth through the surf just off the shore, herding algae-tainted water toward the intake.

By day’s end, thanks partly to uncooperative winds and waves, officials had decided to extend work into today to remove remaining algae.

“There might be times when it’s going to be a more efficient operation than others because of the meteorological conditions, but my sense was that it was working today,” said Charles Knauf, a county environmental health analyst working on the test.

Public swimming areas on Lake Ontario have been bedeviled for years by algae that grow on the lake bottom, break loose and wash ashore. By making the water cloudy and sometimes creating a habitat for bacteria, algae contribute to beach closures.

Ontario Beach has it bad because the west pier at the river mouth traps algae that otherwise would be carried away by the lake’s current.

Beginning more than a decade ago, the Corps of Engineers spent more than $2 million investigating various ideas for addressing the problem. One approach was construction of a large fixed-in-place pumping system, but its $10 million cost was considered far too high by local officials, who would have to foot the bill for any permanent algae-removal system.

This summer’s test, billed as one final effort to find an affordable solution, involved a small, portable system that could be deployed when needed. Two or three people are needed to run it, but some of them work at the beach already.

There’s no cost estimate yet of how much it would cost to make the system a fixture at the beach, though Knauf said it likely would be “extremely inexpensive” compared to the larger fixed pump system.

Ironically, the test period was extended because, until recent days, there had been little algae to test.

“The conditions right until two weeks ago were just astronomical,” Knauf said. “In general, conditions have been the best I’ve seen in 15 years down there.”

So far this summer, Ontario Beach has been closed only five days. Durand-Eastman beach, to the east, has closed only three days.

Fighting against global warming and increasing greenhouse gas concentrations, the regimentation of CO2 emission are the justification for the European Commission to set up the European Directive 2005/32/EC. This and several amending directives describe a framework of eco-design requirements for energy using products asking for increased efficiencies. New standards and norms have been written and others have been updated which now need to be considered in new product engineering projects. Furthermore, energy costs are rising constantly and will continue to rise in the future.

Considering these aspects the design of modern furnaces has changed recently. New designed vacuum furnaces are operating much more efficient than older furnaces. Also modern steel degassing plants use more and more mechanical vacuum systems instead of energy-wasting steam ejector systems. Also here, modern vacuum pumps and pump systems, designed to support these energy saving attempts, have proven their capabilities.

High reliability can be reached by using traditional technologies as e.g. oil-sealed rotary piston or rotary-vane pumps, roots blowers and diffusion pumps, but also also more modern technologies such as dry screw pumps already have a proven track record to work most reliable even under harshest conditions. Today’s standard dry pumps are screw pumps with variable pitch rotor design. Continues compression along the rotor length minimizes the energy demand. Older technologies with constant screw pitch or even dry pumps based on multiple stages of roots- or claw type rotors, have significantly higher power consumption due to design and pumping principle. But even the plurality of today’s screw-pumps with variable pitch differs a lot from each other. Most pumps of the 600 m³/h class demand app. 10 kW power at typical furnace operation pressures below 1 mbar, which is a clearly higher value as those of a comparable rotary-vane pump.

The Dryvac pump series of Oerlikon Leybold Vacuum are optimized with regard to the mechanical rotor design, the electrical motor concept and by selection of a perfectly matched build-in frequency converter.The achieved result in energy saving is substantial, as the pump only consumes 6.9 kW at 1 mbar, is even more energy efficient than a rotary-vane pump and therefore is the new bench mark for power consumption in the market. The build-in frequency converter also offers potential for additional savings and higher process control. Many process steps do not require “full-power” suction speed, especially during operation at rougher pressures, e.g. during carburizing.

Soft start and ramping functionality can be realized with the variable frequency drive. Chamber pressure can be controlled by varying the rotational speed. The customer can even realize a process specific “standby condition” considering certain valve positions to save for example the volume of supplied Nitrogen. Next to these environmental issues, the modern design of the Dryvac eliminates sensitive components as shaft- seals or couplings which clearly increase robustness and reliability of the pump.

Modern designed pumps improve the energy consumption, but several measures can also improve the situation with traditional pumps. Oil-sealed pumps and roots-pumps need to be equipped with newest standard IE2-motors and can be operated with frequency converters to deliver just as much suction speed as required. Oil-diffusion pumps can be equipped with innovative control-systems which can identify the actual power demand and regulate the power supply of the heaters accordingly. These measures diminish the power consumption of a diffusion pump by more than 30 per cent.

The concave shape of the barrel allows the pump to be attached direct to the frame without the need for separate pump clips or a bottle-cage-mounted holder. A good idea in principle, but this assumes your frame tubes are cylindrical or ovoid - at least in the area where you want to fix the pump. In most cases, assuming you’ve got two bottle cages, this means putting the pump on the underside of the top- tube, but that’s only possible if your back brake cable runs along the upper side.

Once you’ve got over that hurdle, the pump is secured by two nylon straps with Velcro tabs. Fitting the pump before a test-ride, I couldn’t get the Velcro straps tight enough, and the pump rattled very slightly. There are small rubber studs on the pump to prevent damage to the frame, but these seemed not totally effective at stopping movement. Actually, they’re not rubber, but something called Kraton, which is also used on things like knife handles and golf clubs. All good stuff; perhaps if these studs were bigger, the rattling wouldn’t occur.

Having said that, the BBB website indicates that the pump comes with a rubber strap, rather than the nylon straps that came with our test model. This should help keep the pump tight against the frame. I got round the problem by fixing the pump onto my frame with insulation tape. Employing the same technique, you could also possibly attach the pump to a seat-tube or down-tube, thereby avoiding the need for a top-tube with cable on the upper side.

The Oval Integrate pump comes in three sizes. A true mini version (230mm), a large version (430mm) and a medium (330mm) which we’re testing here. The medium version seems to be a good compromise and avoids the issues common to all minipumps (low weight but takes all day to get a tyre up to pressure) and full-sized pumps (get the tyre up quickly, but weigh a lot and don’t fit many modern frames). The slim-line design of the Oval Integrate also compares well against some other medium-sized pumps which are bulky and spoil the lines of a nice bike.

Medium or not, the concave shape of the barrel inevitably means it has a smaller capacity than a cylinder the same diameter, so it still takes a while to get a road tyre up to pressure. In the road.cc lab, it took 220 thrusts on the medium sized pump to get a
700×23 tyre up to 100psi. And the last 10psi were a bit of an effort to get in - maybe not surprising, as the pump’s maximum psi is given as 115psi. If you’re using it for get-you-home emergency situations, then 70psi will be fine and much easier to attain. And if you’re touring or commuting and normally run your tyres at around 70psi anyway, then all this high pressure talk is academic.

Whatever pressure you go for, pumping is made more comfortable by the shape of the handle, which swivels out to form a broad pad in the palm of your hand (and also has a covering of Kraton), although if you don’t hold it firmly it rocks on its pivot, which is annoying and actually makes pumping harder. The piston also rocks a little in the barrel when you pump hard, but the seals seem good, and there’s no sign of air escaping. The pump has a direct push-on fit with a small lock/unlock lever, so no hose to screw separately onto the valve.

The Oval Integrate’s unusual design and attachment technique takes a while to get your head around, and you need to make sure you’ve got the pump tightly and safely fixed to your frame, but if you don’t like genuine mini pumps (because they’re too slow) or some other medium-sized pumps (because they’re too bulky and look ugly on your bike), or full-size pumps (because they’re too heavy or don’t fit your frame), then the medium-sized Oval Integrate might be a good option to consider.

All the Oval Integrate pumps are available in black or silver, with the medium retailing at around £25 in bike shops, and around £20 at the usual on-line stores. I was going to say ‘this is a fair price compared to other similar products’. But as there’s nothing
else like it, I’ll just have to say it’s a fair price, period.

Water pumping station in order to start the pump light load is usually required to close the pump outlet valve, and then start the water pump, when its speed up to rated speed then, and then gradually open the outlet valve; system in order to prevent the media back,You must also pump outlet check valve; as ordinary swing check valve closure often produce instantaneous water hammer pump system-threatening accident, therefore I have set the device to effectively eliminate water hammer.

More use of electric current butterfly (gate) valve supporting micro Slow Close Check Valve to achieve these goals, but in the field of electric butterfly (gate) valve closed often appear lax, the motor burned out, and gear transmission corruption and other failures:Micro Slow Close Check Valve narrow scope of adaptation, can not adapt to traffic, large changes in pressure, and the adjustment needle easily blocked, leading to damper movement and other faults can not affect the normal safe water supply.

A multifunctional pump control valve Profile

Multifunctional Pump Control Valve is a new hydraulic control valve, a valve can replace electric butterfly valve, gate valve, check valve and water hammer eliminator three kinds of devices. It can automatically open when the pump is slow to open, stop the pump when the speed of closing and slow closing, without any electrical power and control and other human, and without hydraulic device.

Multifunctional Pump Control Valve The main advantages are:
(1) No action control. Before and after pump start and stop using the water pressure when the valve as the control power, with open and close automatically with the pumps open and close function.
(2) the process of valve opening and closing action can effectively prevent water hammer due to the increase of the pressure wave generated by an accident. According to the survey and measured field use, stop pump water hammer pressure peaks were less than 1.3 times the working pressure.
(3) No on-site commissioning for a wide range of conditions.
(4) Basic maintenance-free. Due to a valve replacement three valves, maintenance and repair workload greatly reduced.
(5) resistance loss. The streamlined, wide-body design, the resistance loss than similar foreign products by 50% or more, such as DN200 products in the v = 2m / s flow rate of economic conditions, the multifunctional pump control valve loss of 0.7m, while the similar foreign products of 1.5m.

Second, multifunctional pump control valve structure and working principle

2.1 Structure
Multifunctional pump control valve structure shown in Figure 1, the main valve and exterior accessories. Including the main valve body,main valve plate, slowly closing the valve plate, stem, seat and diaphragm controller (with valve cap, diaphragm seat, diaphragm, diaphragm plate): exterior accessories include control valves, filters , emptying valve, micro valve. Which micro check valve is specially designed accessories, located in the direction of its limited flow-return hole.

2.2 Works
Pump before the start of the valve outlet pressure in the main valve plate, valve in the closed position, while the upper diaphragm chamber controller connected pressure water, then with the valve chamber under low pressure inlet connected.

Pump starts, the valve inlet pressure gradually increased, while the water pressure through the valve inlet side of the connection tube slowly into the diaphragm chamber under control, the slow realization of the main valve plate opening, opening speed can be adjusted through the control valve.

Pump shutdown, the valve inlet pressure to reduce, when close to zero flow, the main valve plate in its own gravity quickly closed. Reduced due to the valve inlet pressure, the valve outlet pressure water through the connecting pipe into diaphragm chamber on the controller, under water through the valve inlet chamber side of the connecting pipe back to the valve inlet pressure, slow closing valve plate slowly closed, Slow off time can be adjusted through the control valve. The speed of closing the main valve plate closing the valve plate of slow relaxation in line with a two-stage closed-off law, can effectively eliminate water hammer.

Third, several technical problems

3.1 connecting pipe design components
The role of micro check valve is to ensure that the valve open longer than the motor start-up time, light load motor start; the same time to avoid opening the valve too fast and cause water hammer Kai pump. Valve open time by the control valve pressure settings according to scene conditions.
Diaphragm control valve controller can be adjusted up and down the chamber and out of the water flow rate to adjust slowly closing time; off controller can overhaul patch; in normal operation the pump can also manually operate the valves to open and close the valve.
Membrane filter is to ensure that the controller up and down the chamber of water cleanliness. As the valve is in an open process flow back and forth out of itself with the backwash effect, it can also be used for medium poor condition.

With more and more heart disease, the use of heart pumps more and more frequent.When an ailing heart can’t move blood on its own, an implanted pump can help keep it flowing smoothly. But there’s a major drawback: the power supply is large, must be housed outside the body, and is usually connected to the pump via an electric cord that runs through the abdominal wall—a source of constant irritation and potential infection.

Researchers have now demonstrated a prototype wireless heart pump that eliminates the need for the cord altogether. And unlike some wireless implants, it is reliable and efficient over a range of distances, from a few centimeters to a meter or more.

The pump was developed by Josh Smith, associate professor of computer science and electrical engineering at the University of Washington, and Pramod Bonde, a heart surgeon at the University of Pittsburgh Medical Center, and presented at the American Society for Artificial Internal Organs’ annual meeting in Washington, D.C., last month.

Most implanted medical devices, such as pacemakers and defibrillators, can work with internal batteries, but heart pumps and artificial hearts require more power. An artificial heart called the AbioCor is powered wirelessly, but the power transmitter,
affixed to the skin, has to stay aligned with the receiver inside the body. “Just a few millimeters of separation and misalignment results in energy loss,” says Bonde.

Smith and Bonde’s new wireless pump gets around the alignment problem by modifying the way power is sent and received. The external power transmitter is a metal coil that emits an oscillating magnetic field around 6.78 megahertz and 13.56 megahertz. The receiving coil inside the body is tuned to resonate with the frequency of the transmitting coil at about 80 percent efficiency. When the distance between the coil changes, however, the efficiency drops, unless it is possible to adjust the frequency over which the power is transferred. Smith has designed a feedback system that maximizes efficiency by automatically adjusting the frequency of the power transfer.

Transferring power via a magnetic field instead of an electric field avoids harmful heating, but there is still a slight rise in temperature from a residual electric field. Smith says that eliminating some of the coil packaging will ultimately reduce heating to
a negligible amount.

The new wireless power system could free up heart-pump designers to innovate. A power supply that can operate over a range of distances could be worn in a vest or even installed in a house. Smith and Bonde envision a whole-home system in which a person can move freely without wearing a power supply. A small implantable battery could also offer a half-hour of backup power.

Recent work in wireless power transfer has focused mainly on increasing efficiency, says Matt Reynolds, assistant professor of electrical and computer engineering at Duke University. “Adapting to movement by tuning the operating frequency and maintaining resonance,” he says, “is also critical to achieving widespread acceptance of this technology.”
