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.

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.

PVQs operate at quietness levels that meet today"s demanding industrial conditions. The sound level of each unit approaches or is below that of the electric motor driving it. Sound is reduced by a patented timing arrangement that also produces low pressure“pulses” in the outlet flow. This leads to reduced tendencies for noise in systems using PVQs.

The PVQ series is capable of operating with many types of hydraulic fluid. Water-content and phosphate ester fluids can be accommodated, in addition to the typical petroleum based and synthetic fluids.

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.

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.

The unique design of the PQ120 Series electric hydraulic pump allows operators to start and operate under full load, even with voltage reduced by 10%. It is suitable for cylinders of up to 400 tons and is designed specifically for heavy-duty operation with a throughput of up to 1.6 litres per minute.

Noise originates at the pump, and system designers can"t do much about that, but they can deal with several additional factors that contribute to and determine the final noise level.

When vibrations (in the form of longitudinal pressure waves) in the sonic or acoustic range reach the ear - whether transmitted through air, liquid, or solid - the person receiving those vibration hears sound. If the sound is unpleasant - because it lacks agreeable musical quality or is too loud it becomes noise. Excessive noise can be mentally and physically dangerous for workers. For both mandated and marketing reasons, much work has been done on reducing noise in the workplace over the past decade. Sound-producing components, such as pumps, are tested for noise generation and their ratings are published as part of their basic specification.

Yet, if you walk through any large automotive plant, you"ll probably pass some hydraulic power units that have sound-deadening enclosures built around them. The presence of a sound enclosure often indicates that the power unit did not operate at the sound rating shown in the manufacturer"s catalog for the pump. In other words, the catalog sound rating for the pump is usually much lower than the sound rating for the completed hydraulic power unit. Something happens during assembly of the power unit to metamorphose a relatively quiet pump into an unacceptably noisy power unit.

It"s generally understood that pump pressure and pump size have about an equal effect on the hydraulic noise that a pump will generate. hi addition, pump speed has about 300% greater affect on noise than either pressure or size. (This is the reason some pump manufacturers recommend lower-speed electric motors.) And fixed displacement pumps are usually quieter than variable-displacement models. But all of these factors are noted in the pump catalog. Something else - not mentioned in the catalog - is contributing to the increase in noise level.

The problem is that any slight noise generated by the pump is amplified throughout the structure of the hydraulic equipment. Lab tests show that pump noise levels are increased by 2 to 3 dB (A) just by adding 12 ft. of outlet and return lines. These lines do not generate noise - instead they radiate noise when they respond to pulsations or vibrations generated by the pump. Long hydraulic lines, whether pipe, tube, or hose, also frequently provide the primary path for propagating pulsations from the pump to components - such as the large flat metal surfaces the typically are part of hydraulic reservoirs - that react to them and radiate even higher noise levels. These phenomena help to explain why many pumps have a low noise rating, but when they are installed on a power unit, the assembly"s noise rating is much higher.Taking control of noiseIn any hydraulic system, the pump is the main source of pulsations and vibrations. While pump manufacturers have made noise reduction a design goal, every pump still produces some ripple the pump manufacturers" term for pulsations. Ripple produces the line vibrations which cause additional noise. System designers cannot change how much ripple the pump produces, so they must find ways to control the propagation of that ripple out through the rest of the system.

One of the first areas that should be reviewed when attempting to reduce power-unit noise is the hydraulic conductors. Somewhat surprisingly, one factor that can contribute much to the noise level is improper use of hydraulic hose. Recent research at a large pump manufacturer showed that they could take an average of 5 dB(A) out of a standard power unit merely by changing the configuration of the hydraulic hose. Frequently, a 90" curved hose is used when a horizontal line has to be connected to a vertical line, and 180" hose curves also are quite common. Experiments show that both of these configurations actually increase system noise level. The solution. don"t bend hydraulic hose; instead, substitute bent metal tubing, Only use hose in a relatively straight line.

It is well known that introducing a compressible medium such as nitrogen into the relatively incompressible medium of hydraulic fluid will help reduce pulsations. The challenge is to get the fluid to interact with the nitrogen so the nitrogen compresses and the fluid merely loses its pulsation.

Over the years, nitrogen-charged accumulators have been installed in many hydraulic circuits to absorb pulsations. At first, accumulators were used as appendage devices - teed off the hydraulic line. The designer hoped that the pulsations would wander into the accumulator. However, experience showed that the majority of the pulsations bypassed the line leading to the accumulator. Different designs then involved in which the full flow was diverted into the accumulator. Correctly sizing this type of accumulator is complicated and the circuit that directs flow into the accumulator is very expensive. Also, pressure drop through these accumulators may be unacceptably high.

Another method of using compliant nitrogen to deal with noise-causing pulsations is to mount an in-line nitrogencharged noise suppressor right at the outlet of the pump. (This suppressor is described in detail in the box at right.) This design is more efficient than a large conventional accumulator because the fluid flow-path to the bladder is short and unrestricted, and the fluid contacts a much greater bladder area,

Pulsations enter the suppressor and then pass through the three baffles - a total radial distance of only in. - and strike the bladder, which typically is charged at 50 to 60% of the hydraulic system operating pressure. The bladder deflects each time it is hit by a pulsation, and this slight deflection absorbs and reduces noise - and as a bonus, any shock waves. The bladder"s large area, its ability to oscillate at high frequency, and short travel distance combine to absorb pulsations with frequencies above 600 Hz.

The size of the suppressor is determined simply by the size of the hydraulic line in which it will be installed. Models are available for pipe and tube sizes from 3/8 to 3 in., with NPT pipe, SAE rube, and splitflange port connections. Sizing older-style, accumulator-type hydraulic pulsation dampeners was a long and complicated process. With this design, the size of the line becomes the size of the suppressor.

One pump manufacturer built 60 double-pump power units for an automotive plant. The completed power units registered a noise level of 90 dB(A), but the plant"s noise specification was 82 dB(A). The manufacturer decided that the least expensive solution was to install inline noise suppressors directly at the outlet of the pumps. The suppressors brought the noise level down to 78 dB(A), and the cost was considerably less than building noise enclosures around the power units.

With a simple but sophisticated design, we offer a gear pump that not only is quieter. It also has a unique advantage over the most popular low noise gear pump. The shhark® patented design guarantees the pump will remain silent after many hours of heavy-duty operation. This offers costs savings over traditional gear pump by eliminating costs associated with external noise reduction devices.

The shhark® design offers up to 10 dB noise reduction over regular gear pumps. It is ideal for application where low noise and high efficiency are required. Typical applications include tractors, indoor lift trucks, aerial platforms, construction equipment, material handling, agricultural and lifting devices.
