Continuum pumps are used to pump fluids in a continuous flow. They are often used in industries such as the chemical, oil and gas industry, water treatment plants, and power stations as well as in forklifts, machine tools, and on boats.

These silent pumps’ helical rotors don’t trap any fluid volume. Continuum pumps run highly efficiently while still producing minimal sound, continuous flow can be maintained even at maximum operating speed. They produce exremely low vibrations and low pulsations, operating silently which helps to not disrupt operations and prevent noise pollution or complaints.

Pumps are a vital part of any water or wastewater project, and choosing the right one is an important decision. Continuum pumps are one of the most popular options because they offer a number of advantages over other types, such as centrifugal pumps.

The Shore Western WhisperPak series quiet submerged pumps are acoustically treated laboratory quality hydraulic power supplies designed to meet the exacting requirements of servo-hydraulic control systems. These power supplies utilize quality components and micro-clean filtration to provide trouble-free long life with minimum maintenance. A complete system of interlocks and controls allow failsafe unattended continuous operation.. Low noise level and leak-free components allow placement directly in the laboratory next to the test equipment. These pumps are ideal when hydraulic power is needed close to the test machine and the cost of installing a large centralized pump-room based HPS is impractical or too expensive.

The industry-leading low noise level of these pumps is achieved by the use of inherently quiet components and insulated cabinetry, and submerged pump/motor units inside the stainless steel hydraulic oil tank. The pumping assembly is mounted with isolators in a completely sealed, acoustically treated enclosure to eliminate airborne noise and prevent heat discharge into the surrounding environment. Output is connected through low velocity flexible hoses to a piping interface manifold. All high pressure connections utilize o-ring fittings or welded joints to eliminate external oil leaks. Units range in size from 7.5 gpm to 180 gpm (30 lpm to 700 lpm) . Standard units are wired for 380/460 VAC, 3 phase, 50/60 Hz. Other voltages and frequencies are available.

Others have found that using a submerged-pump configuration can lead to overheating oil when the system flow demands are low. To solve this problem, we have developed a unique and very reliable solution. By installing a through-drive on the pump, we are able to run a second small pump in series, which is dedicated to circulating oil through a cooling and filtering circuit. This ensures that the oil maintains a stable temperature regardless of demand, and is kept cleaner by filtering through a kidney-loop. This is a more efficient than the bypassing approach taken by our competitors.

These gear pumps are specified with helical teeth and a special finishing process that significantly reduce hydraulic pulsation of the oil flow, resulting in lower noise levels and consequently recommending them as the best option for all mobile equipment and industrial applications where superior acoustic comfort is a requirement.

Quiet-running and modular. Aluminium and cast iron components of the silent series are designed applying the same modular logic as adopted for conventional pumps. Accordingly, multiple pumps can be assembled using silent stages together with conventional stages, and silent pumps can also be equipped with all the accessories available for other series. Silent pumps with cast iron body, besides being suitable for heavy duty applications, also offer better performance in terms of mechanical noise reduction.

Noise reduction is indeed becoming the real challenge for today’s industrial market. Market competitiveness and new European regulations in the handling sector, particularly for pallet trucks, are such that the suppliers are impelled to develop new technologies meeting increasing requirements from their customers.Acoustic nuisances have several origins: the pump hydraulic pulsations, being propagated through hoses and pipes, and then affecting the truck structure via the frame (structure-borne sound) and the aerial noise (rotation frequency of an electric motor or a pump) which can be contained by an acoustic cover.

Comparison of 1cc/rev and 1,25cc/rev capacities using standard and silent pinion technology. The tests were realized in JTEKT HPI own anechoic room on a power pack with 1,2kW motor.

In order to lessen the hydraulic pulsations, we designed a specific helical tooth profile with a suitable propeller angle and increased the number of teeth of the pinions from 12 to 22.

The acoustic results show that the noise level has been reduced by an average of -10 dBA, when compared with a standard external gear pump. The new HPI Silent Pump is also characterized by a much more pleasant sound when in use. Indeed, the operating frequency ranges have been adapted for optimized working conditions for the user. The 22-tooth helical profile on series 0 pumps, unique for that size of pumps, reduces significantly the hydraulic pulsations. The capacities available are 1 – 1,25 – 1,5 – 1,7 – 2 cc/rev for operating pressures from 125 to 250 bar.

This rotor profile has a single point of contact and completes an overlap which eliminates any trapped volume of fluid. The result is a silent, continuous transmission of fluid when compared to the pulsations of a traditional gear pump.

PGP500H series pumps reduce noise, pulsations and vibrations from the hydraulic system and offer high pressure performance. They are perfect for industrial and mobile applications sensitive to noise such as electric and hybrid vehicles.

On electric vehicles, low noise is a key requirement, while low-speed operation enables improved control and positioning for various vehicle functions. This means that gear pumps which can operate efficiently and quietly at low speeds are among the most important priorities for electric vehicle designers. WISPY technology is also attractive in other market.

We developed a range of WISPY pumps in displacements from 4cc to 29cc. The company established itself as a leader in low-noise gear products a decade ago when it introduced the first WISPY series (quiet) gear pump product line. WQ introduced the concept of true dual flank engagement of the gear teeth (as opposed to “near dual flank engagement”), which is unique to VBC Hydraulics and which reduces the amplitude of the pressure pulsations introduced into the hydraulic system. WISPY is a significant step forward in low noise technology in that it reduces noise by up to 10 dB or 85% in low-speed applications. Low speeds at high pressure are the most severe condition for gear pump technology. The pump, features innovative tooth geometry, true dual-flank gear engagement, reduced trapped oil volume and advanced trapped oil management. The design reduces pressure pulsation by 70%, which is the key factor determining the pump"s noise levels, while also reducing energy consumption.

Both static and in-vehicle tests have demonstrated that WISPY series pumps offer significantly lower noise operation when compared with other external gear pumps. In many cases, they can also match or even out-perform more expensive internal gear pumps on efficiency and low-noise operation.

Hydraulic systems are in general members of the fluid power branch of power transmission. Hydraulic pumps are also members of the hydraulic power pack/hydraulic power unit family. Hydraulic units are encased mechanical systems that use liquids for hydraulics.

The hydraulic systems that hydraulic pumps support exist in a range of industries, among them agriculture, automotive manufacturing, defense contracting, excavation, and industrial manufacturing. Within these industries, machines and applications that rely on hydraulic pumps include airplane flaps, elevators, cranes, automotive lifts, shock absorbers, automotive brakes, garage jacks, off-highway equipment, log splitters, offshore equipment, hydraulic motors/hydraulic pump motors, and a wide range of other hydraulic equipment.

When designing hydraulic pumps, manufacturers have many options from which to choose in terms of material composition. Most commonly, they make the body of the pump–the gears, pistons, and hydraulic cylinders–from a durable metal material. This metal is one that that can hold up against the erosive and potentially corrosive properties of hydraulic fluids, as well as the wear that comes along with continual pumping. Metals like this include, among others, steel, stainless steel, and aluminum.

First, what are operating specifications of their customer? They must make sure that the pump they design matches customer requirements in terms of capabilities. These capabilities include maximum fluid flow, minimum and maximum operating pressure, horsepower, and operating speeds. Also, based on application specifications, some suppliers may choose to include discharge sensors or another means of monitoring the wellbeing of their hydraulic system.

Next, what is the nature of the space in which the pump will work? Based on the answer to this question, manufacturers will design the pump with a specific weight, rod extension capability, diameter, length, and power source.

Manufacturers must also find out what type of substance does the customer plan on running through the pumps. If the application calls for it, manufacturers can recommend operators add other substances to them in order to decrease the corrosive nature of certain hydraulic fluids. Examples of such fluids include esters, butanol, pump oils, glycols, water, or corrosive inhibitors. These substances differ in operating temperature, flash point, and viscosity, so they must be chosen with care.

All hydraulic pumps are composed in the same basic way. First, they have a reservoir, which is the section of the pump that houses stationary fluid. Next, they use hydraulic hoses or tubes to transfer this fluid into the hydraulic cylinder, which is the main body of the hydraulic system. Inside the cylinder, or cylinders, are two hydraulic valves and one or more pistons or gear systems. One valve is located at each end; they are called the intake check/inlet valve and the discharge check/outlet valve, respectively.

Hydraulic pumps operate under the principle of Pascal’s Law, which states the increase in pressure at one point of an enclosed liquid in equilibrium is equally transferred to all other points of said liquid.

To start, the check valve is closed, making it a normally closed (NC) valve. When the check is closed, fluid pressure builds. The piston forces the valves open and closes repeatedly at variable speeds, increasing pressure in the cylinder until it builds up enough to force the fluid through the discharge valve. In this way, the pump delivers sufficient force and energy to the attached equipment or machinery to move the target load.

When the fluid becomes pressurized enough, the piston withdraws long enough to allow the open check valve to create a vacuum that pulls in hydraulic fluid from the reservoir. From the reservoir, the pressurized fluid moves into the cylinder through the inlet. Inside the cylinder, the fluid picks up more force, which it carries over into the hydraulic system, where it is released through the outlet.

Piston pumps create positive displacement and build pressure using pistons. Piston pumps may be further divided into radial piston pumps and axial piston pumps.

Radial pumps are mostly used to power relatively small flows and very high-pressure applications. They use pistons arranged around a floating center shaft or ring, which can be moved by a control lever, causing eccentricity and the potential for both inward and outward movement.

Axial pumps, on the other hand, only allow linear motion. Despite this, they are very popular, being easier and less expensive to produce, as well as more compact in design.

Gear pumps, or hydraulic gear pumps, create pressure not with pistons but with the interlocking of gear teeth. When teeth are meshed together, fluid has to travel around the outside of the gears, where pressure builds.

External gear pumps facilitate flow by enlisting two identical gears that rotate against each other. As liquid flows in, it is trapped by the teeth and forced around them. It sits, stuck in the cavities between the teeth and the casing, until it is so pressurized by the meshing of the gears that it is forced to the outlet port.

Internal gear pumps, on the other hand, use bi-rotational gears. To begin the pressurizing process, gear pumps first pull in liquid via a suction port between the teeth of the exterior gear, called the rotor, and the teeth of the interior gear, called the idler. From here, liquid travels between the teeth, where they are divided within them. The teeth continue to rotate and mesh, both creating locked pockets of liquid and forming a seal between the suction port and the discharge port. Liquid is discharged and power is transported once the pump head is flooded. Internal gears are quite versatile, usable with a wide variety of fluids, not only including fuel oils and solvents, but also thick liquids like chocolate, asphalt, and adhesives.

Various other types of hydraulic pumps include rotary vane pumps, centrifugal pumps, electric hydraulic pumps, hydraulic clutch pumps, hydraulic plunger pumps, hydraulic water pumps, hydraulic ram pumps, portable 12V hydraulic pumps, hydraulic hand pumps, and air hydraulic pumps.

Rotary vane pumps are fairly high efficiency pumps, though they are not considered high pressure pumps. Vane pumps, which are a type of positive-displacement pump, apply constant but adjustable pressure.

Centrifugal pumps use hydrodynamic energy to move fluids. They feature a rotating axis, an impeller, and a casing or diffuser. Most often, operators use them for applications such as petroleum pumping, sewage, petrochemical pumping, and water turbine functioning.

Electric hydraulic pumps are hydraulic pumps powered by an electric motor. Usually, the hydraulic pump and motor work by turning mechanisms like impellers in order to create pressure differentials, which in turn generate fluid movement. Nearly any type of hydraulic pump can be run with electricity. Most often, operators use them with industrial machinery.

Hydraulic clutch pumps help users engage and disengage vehicle clutch systems. They do so by applying the right pressure for coupling or decoupling shafts in the clutch system. Coupled shafts allow drivers to accelerate, while decoupled shafts allow drivers to decelerate or shift gears.

Hydraulic ram pumps are a type of hydraulic pump designed to harness hydropower, or the power of water, to elevate it. Featuring only two moving hydraulic parts, hydraulic ram pumps require only the momentum of water to work. Operators use hydraulic ram pumps to move water in industries like manufacturing, waste management and sewage, engineering, plumbing, and agriculture. While hydraulic ram pumps return only about 10% of the water they receive, they are widely used in developing countries because they do not require fuel or electricity.

Hydraulic water pumps are any hydraulic pumps used to transfer water. Usually, hydraulic water pumps only require a little bit of energy in the beginning, as the movement and weight of water generate a large amount of usable pressure.

Air hydraulic pumps are hydraulic pumps powered by air compressors. In essence, these energy efficient pumps work by converting air pressure into hydraulic pressure.

Hydraulic pumps are useful for many reasons. First, they are simple. Simple machines are always an advantage because they are less likely to break and easier to repair if they do. Second, because fluid is easy to compress and so quick to create pressure force, hydraulic pumps are very efficient. Next, hydraulic pumps are compact, which means they are easy to fit into small and oddly shaped spaces. This is especially true in comparison to mechanical pumps and electrical pumps, which manufacturers cannot design so compactly. Speaking of design, another asset of hydraulic pumps is their customizability. Manufacturers can modify them easily. Likewise, hydraulic pumps are very versatile, not only because they are customizable, but also because they can work in places where other types of pump systems can’t, such as in the ocean. Furthermore, hydraulic pumps can produce far more power than similarly sized electrical pumps. Finally, these very durable hydraulic components are much less likely to explode than some other types of components.

To make sure that your hydraulic pumps stay useful for a long time, you need to treat them with care. Care includes checking them on a regular basis for problems like insufficient fluid pressure, leaks, and wear and tear. You can use diagnostic technology like discharge sensors to help you with detect failures and measure discharge pressure. Checking vibration signals alone is often not enough.

To keep yourself and your workers safe, you need to always take the proper precautions when operating or performing maintenance and repairs on your hydraulic pumps. For example, you should never make direct contact with hydraulic fluid. For one, the fluid made be corrosive and dangerous to your skin. For two, even if the pump isn’t active at that moment, the fluid can still be pressurized and may potentially harm you if something goes wrong. For more tips on hydraulic pump care and operation, talk to both your supplier and OSHA (Occupational Safety and Health Administration).

Pumps that meet operating standards are the foundation of safe and effective operations, no matter the application. Find out what operating standards your hydraulic pumps should meet by talking to your industry leaders.

With the SILENCE PLUS Rexroth introduces a new generation of external gear pumps whose noise level has been reduced by an average of 15 dB(A) compared with a conventional external gear pump. The new pump is also characterized by a subjectively much more pleasant, deeper sound.

The RKP-D family of products has an intelligent control mechanism that allows the user to optimize the usage of control entities within a hydraulic system, often making the need for central control hardware redundant

Moog is the leading supplier for Radial Piston Pumps (RKP) worldwide. This mature and robust product has been used for decades and runs today in over 100,000 machines in various applications around the globe. It is widely known for its robust and reliable design.

The Moog Radial Piston pump comes in 8 pump sizes between 19 cc and 140 cc per revolution (19, 32, 45, 63, 80,100, 140 and 250) and has a maximum speed range of 1,800 to 2,900 rpm

Large selection of controls, including standard pressure compensator (Type F), remote pressure compensator (Type H), pressure and flow control (Type J,R) and digital electro-hydraulic control (RKP-D)

It is the central task of external gear pumps to convert mechanical energy (torque and speed) into hydraulic energy (flow and pressure). To reduce heat losses, Rexroth’s external gear units offer very high efficiencies. They are realized by pressure-dependent gap sealing and highly precise production technology.

Rexroth external gear pumps are built in four frame sizes: Platform B, F, N and G. Within each platform different displacements can be realized by different gear widths. The pumps are available in the versions Standard, High-Performance, SILENCE und SILENCE PLUS. Further configuration variants are given by different flanges, shafts, valve arrangements and multiple pump combinations.

In order to reduce piping complexity, a flow control valve or pressure-relief valve can be integrated in the cover of the gear pump. Such solutions are used, for instance, for the hydraulic oil supply of power steering systems. The pump delivers a constant flow irrespective of the rotational speed. The residual flow is either returned internally to the suction port or distributed externally to other consumers.

PGH-type hydraulic pumps are gap-compensated internal gear pumps with fixed displacement. The hydrodynamically mounted pinion shaft drives the internal gear. The pinion shaft and internal gear tooth clearances opening in the suction range suck in the hydraulic fluid and transport it to the pressure range. The suction and pressure range are separated by the radial compensation elements and the tooth engagement between the internal gear and pinion shaft.
