A hydraulic pump is a mechanical power source which converts mechanical power into hydraulic energy. A hydraulic pump does not create energy, but converts energy into a form which can be utilized by the hydraulic system. Although pumps come in various shapes & sizes with different pumping mechanisms, their sole purpose is to convert the mechanical energy of the prime mover ( eg. an electric motor) into hydraulic enerqy. They do this simply by pushing hydraulic fluid into the systemHydraulic pumps convert mechanical energy  (torque speed ) into hydraulic energy (flow, pressure)

In most industrial hydraulic systems, the prime mover is an electric motor. The rotary motion of the prime mover creates a flow of fluid from the outlet of the pump.

There are two types of displacement: a fixed displacement pump is a positive displacement design in which the amount of the displacement cannot be  varied. At a given input RPM, the pump must deliver flow in an amount equivalent to its fixed displacement, on the other hand, a variable displacement is a type of pump which its displacement can be changed easily.

In general all three design classification are applicable to fixed displacement pumps. However only the vane or piston type can be used for variable displacement.

A gear pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for hydraulic fluid power applications.

Norman Equipment has been a leading supplier of hydraulic equipment including hydraulic piston pumps and motors for over 70 years. Full-line authorized stocking distributor of quality hydraulic components and systems from top manufacturers renowned for performance and reliability.

We recommend using the piston pumps in high-pressure applications. In some cases, it is more economical to run a piston pump compensated that puts out a very low output flow until needed. This lowers electric cost and pump wear that may reduce system down time.

Norman currently stocks the Parker Denison PV (PVP) units and is part of the Parker Denison Distribution Network if another unit is needed that is not in stock at Norman Equipment. Denison is one of the most recognized names in hydraulic units in the world. For many years, their products were recognized by their distinctive blue color. Today, the Denison brand is part of the Parker-Hannifin family and all pumps are painted black.

The tips of the vanes are the most vulnerable part of each pump. Because the vanes are held out under pressure and subject to centrifugal forces, the area where the tip moves across the outer ring is critical. Vibrations, dirt, pressure peaks or high local fluid temperatures can all result in a breakdown of the fluid film, resulting in metal to metal contact and reduced service life. With some fluids, the high fluid shear forces created at points like this can damage the fluid and again lead to reduced service life. Although this effect is not limited to vane pumps.

Suction head pressures are very important for vane pumps and must not exceed the manufacturers stated minimum. Always pre-fill the tank suction line and pump casing. It"s always better to make sure the installation has a positive suction head, e.g. the pump is below the fluid level, but never self-prime. Remember that as soon as you remove any valve or break the circuit in any way, it"s likely all of the fluid will drain out of the pipework and back into the reservoir. This will result in the need to re-prime any pumps that do not have positive pressure heads.

Case leakage lines allow all of the fluid that has leaked past the rotating faces to drain back to the reservoir. Without a case leakage line, the pumps would instantly fail. Because these case leakage lines take away the lost fluid, the volume and temperature of the fluid will be directly related to the operating efficiency of the pump. By monitoring the temperature of this fluid and preferably flow, and contamination level as well, you should get a good indication of the condition of the pump and an early warning of potential failures.

This article aims to describe the main features of the vane pump technology, how it works, its advantages and disadvantages, and where it is most commonly used. Finally, we will briefly mention the Fluid-o-Tech vane pumps.

Rotary vane pumps are a type of positive displacement pump. Like all positive displacement pumps, the flow rate is always directly proportional to the speed.

Vane pumps are available with different types of vane: sliding, flexible, oscillating, rotating, and external vanes. The vane pumps are known for their dry-priming, easy maintenance, and good suction characteristics throughout the life of the pump.

A splined rotor is supported eccentrically in a cycloidal cam. The rotor sits close to the cam wall to form a crescent-shaped cavity. The rotor is sealed in the cam by two side plates. The vanes or blades fit into the rotor cavities. When the rotor rotates and fluid enters the pump, the centrifugal force, the hydraulic pressure, and/or the pushrods push the vanes towards the housing walls. The tight seal between the vanes, the rotor, the cam, and the side plate makes this technology powerful for good suction, which is common to the vane pumping principle.

The housing and cam force the fluid into the pumping chamber through holes in the cam (small red arrow on the bottom of the pump). The fluid enters the pockets created by the vanes, the rotor, the cam, and the side plate.

The rotary vane pump is very versatile and can be used in a variety of sectors and applications, from dosing to transferring and repressurizing fluids. Depending on the choice of materials, rotary vane pumps can handle a wide range of clean fluids.

Fluid-o-Tech is able to supply a wide range of rotary vane pumps covering a variety of applications in different sectors. In stainless steel, low-lead brass, technopolymer, direct coupled, magnetic or electromagnetic drive at variable speed, our pumps cover a flow rate range from 30 to 2200 l/h at pressures up to 18 bar. The built-in safety valve, available on request, limits the pressure to protect the pump and the hydraulic circuit.

The Fluid-o-Tech rotary vane pumps, WRAS or NSF certified for use with potable water, are the reference choice in the market of espresso machines and beverage dispensers for professional use.

The maximum operating pressures are similar to those of GHP2 series and extend up to 300 bar. The helical gear ensures the continuity of flow despite the low number of teeth. The low number of teeth reduces the fundamental frequencies of the pump noise, reducing the noise level by an average of 15 dBA compared with a conventional external gear pump. ® The particular shape of the patented Elika profile eliminates the phenomenon of air encapsulation typical of normal gear pumps, curing the source of the main cause of noise and vibrations. Axial forces induced by the helical teeth are optimally balanced in all operating conditions by the axial compensation system integrated in the pump cover. Specific compensation areas in the flange and cover, insulated by special gaskets reinforced with anti-extrusion, allow for free axial and radial movement of the bushings, which is proportional to pump operating pressure. In this way, internal leakage is dramatically reduced, ensuring very good volumetric and mechanical pump performances, as well as proper lubrication of pump’s moving parts. Back and front plates are of anodized aluminum keeping the unit of low weight but up to the ® pressure generated.

External gear pumps are the most popular pumps used in modern hydraulic systems. They feature versatility, strength and long life. Their simple construction ensures cost effective purchasing and service. Thanks to these basic concepts, coupled with ever improving product design and features, result in a quality product manufactured to the very highest standards. Due to the many years of research and experience, accurate material selection, rigid production process and rigorous testing on all aspects of the product range, enables Marzocchi gear pumps to operate under extreme working conditions and transmit high hydraulic power. In addition Marzocchi pumps are produced with good mechanical and hydraulic efficiency, low noise level and their compact dimensions give a low weight too power ratio. A gear pump usually consists of a gear pair supported by two aluminium bushes for groups 0.25, 0.5 and 1P, or bushes with plain bearings coated with anti-friction material for groups 1, 2, 3 and 4, a body, a securing flange and a cover. Shaft of the driving gear projecting beyond the flange mounts a twin-lip seal ring (the inner lip being a seal, the outer lip being a dust seal) for groups 0.25, 0.5 and 1P, or two opposed single-lip seal rings (the outer being a dust seal) for groups 1, 2, 3 and 4. Pump body, flange and cover are made of special high-resistant aluminium alloys for minimized deformation even when subject to high pressure, be it continuous or intermittent or peak pressure. The body is profiled by means of extrusion, whereas flange and cover are obtained by means of die-casting (gravity die-casting for some models). Gears are made of special steel. Their manufacturing process includes case-hardening and quench hardening. The gears are ground and fine finished so as to have a high degree of surface finishing. Proper tooth profile design and geometric proportions ensure low pulsation levels and low noise levels during pump operation. Bushes are made of special low-friction and high-resistant aluminium alloy and manufactured from die-casting. Special compensation zones onto flange and cover, insulated by special seals with anti-extrusion rings, allow fully free axial and radial movement to the bushes, which is proportional to pump operating pressure. In this way, internal leakage is dramatically reduced, thus ensuring very high pump performance (both in terms of flow and overall) and proper lubrication to the moving pump parts.

Also available are spider and gear couplings which are certified to zone 2 standards. (Contact jbj Techniques for details). An important development of equipment for use within hazardous areas is the wet mount series of bellhousings. Commissioned to research and develop a product that would control the high temperature generated by a piston pump shaft seal when working within cycling applications. A little considered issue is the frictional heat generated at the shaft seal when the application requires the pump to cycle between different pressures causing the seal temperature to increase. This process will often take the seal temperature out and above the levels required by the relevant ATEX standards requirement. This specially designed assembly allows a pumped cooling flow to be passed over the seal face and through an auxiliary cooler, this in turn reduces the seal face temperature which can be maintained at an acceptable level. With a vast array of components to select from, jbj are well placed to provide all required components to support the required cooling system.

A gear pump is a type of positive displacement (PD) pump. Gear pumps use the actions of rotating cogs or gears to transfer fluids. The rotating gears develop a liquid seal with the pump casing and create a vacuum at the pump inlet. Fluid, drawn into the pump, is enclosed within the cavities of the rotating gears and transferred to the discharge. A gear pump delivers a smooth pulse-free flow proportional to the rotational speed of its gears.

There are two basic designs of gear pump: internal and external (Figure 1). An internal gear pump has two interlocking gears of different sizes with one rotating inside the other. An external gear pump consists of two identical, interlocking gears supported by separate shafts. Generally, one gear is driven by a motor and this drives the other gear (the idler). In some cases, both shafts may be driven by motors. The shafts are supported by bearings on each side of the casing.

As the gears come out of mesh on the inlet side of the pump, they create an expanded volume. Liquid flows into the cavities and is trapped by the gear teeth as the gears continue to rotate against the pump casing.

No fluid is transferred back through the centre, between the gears, because they are interlocked. Close tolerances between the gears and the casing allow the pump to develop suction at the inlet and prevent fluid from leaking back from the discharge side (although leakage is more likely with low viscosity liquids).

External gear pump designs can utilise spur, helical or herringbone gears (Figure 3). A helical gear design can reduce pump noise and vibration because the teeth engage and disengage gradually throughout the rotation. However, it is important to balance axial forces resulting from the helical gear teeth and this can be achieved by mounting two sets of ‘mirrored’ helical gears together or by using a v-shaped, herringbone pattern. With this design, the axial forces produced by each half of the gear cancel out. Spur gears have the advantage that they can be run at very high speed and are easier to manufacture.

Gear pumps are compact and simple with a limited number of moving parts. They are unable to match the pressure generated by reciprocating pumps or the flow rates of centrifugal pumps but offer higher pressures and throughputs than vane or lobe pumps. External gear pumps are particularly suited for pumping water, polymers, fuels and chemical additives. Small external gear pumps usually operate at up to 3500 rpm and larger models, with helical or herringbone gears, can operate at speeds up to 700 rpm. External gear pumps have close tolerances and shaft support on both sides of the gears. This allows them to run at up to 7250 psi (500 bar), making them well suited for use in hydraulic power applications.

Since output is directly proportional to speed and is a smooth pulse-free flow, external gear pumps are commonly used for metering and blending operations as the metering is continuous and the output is easy to monitor. The low internal volume provides for a reliable measure of liquid passing through a pump and hence accurate flow control. They are also used extensively in engines and gearboxes to circulate lubrication oil. External gear pumps can also be used in hydraulic power applications, typically in vehicles, lifting machinery and mobile plant equipment. Driving a gear pump in reverse, using oil pumped from elsewhere in a system (normally by a tandem pump in the engine), creates a motor. This is particularly useful to provide power in areas where electrical equipment is bulky, costly or inconvenient. Tractors, for example, rely on engine-driven external gear pumps to power their services.

External gear pumps can be engineered to handle aggressive liquids. While they are commonly made from cast iron or stainless steel, new alloys and composites allow the pumps to handle corrosive liquids such as sulphuric acid, sodium hypochlorite, ferric chloride and sodium hydroxide.

External gear pumps are self-priming and can dry-lift although their priming characteristics improve if the gears are wetted. The gears need to be lubricated by the pumped fluid and should not be run dry for prolonged periods. Some gear pump designs can be run in either direction so the same pump can be used to load and unload a vessel, for example.

The close tolerances between the gears and casing mean that these types of pump are susceptible to wear particularly when used with abrasive fluids or feeds containing entrained solids. External gear pumps have four bearings in the pumped medium, and tight tolerances, so are less suited to handling abrasive fluids. For these applications, internal gear pumps are more robust having only one bearing (sometimes two) running in the fluid. A gear pump should always have a strainer installed on the suction side to protect it from large, potentially damaging, solids.

Generally, if the pump is expected to handle abrasive solids it is advisable to select a pump with a higher capacity so it can be operated at lower speeds to reduce wear. However, it should be borne in mind that the volumetric efficiency of a gear pump is reduced at lower speeds and flow rates. A gear pump should not be operated too far from its recommended speed.

For high temperature applications, it is important to ensure that the operating temperature range is compatible with the pump specification. Thermal expansion of the casing and gears reduces clearances within a pump and this can also lead to increased wear, and in extreme cases, pump failure.

Despite the best precautions, gear pumps generally succumb to wear of the gears, casing and bearings over time. As clearances increase, there is a gradual reduction in efficiency and increase in flow slip: leakage of the pumped fluid from the discharge back to the suction side. Flow slip is proportional to the cube of the clearances between the cog teeth and casing so, in practice, wear has a small effect until a critical point is reached, from which performance degrades rapidly.

Gear pumps continue to pump against a back pressure and, if subjected to a downstream blockage will continue to pressurise the system until the pump, pipework or other equipment fails. Although most gear pumps are equipped with relief valves for this reason, it is always advisable to fit relief valves elsewhere in the system to protect downstream equipment.

The high speeds and tight clearances of external gear pumps make them unsuitable for shear-sensitive liquids such as foodstuffs, paint and soaps. Internal gear pumps, operating at lower speed, are generally preferred for these applications.

External gear pumps are commonly used for pumping water, light oils, chemical additives, resins or solvents. They are preferred in any application where accurate dosing is required such as fuels, polymers or chemical additives. The output of a gear pump is not greatly affected by pressure so they also tend to be preferred in any situation where the supply is irregular.

An external gear pump moves a fluid by repeatedly enclosing a fixed volume within interlocking gears, transferring it mechanically to deliver a smooth pulse-free flow proportional to the rotational speed of its gears.

External gear pumps are commonly used for pumping water, light oils, chemical additives, resins or solvents. They are preferred in applications where accurate dosing or high pressure output is required. External gear pumps are capable of sustaining high pressures. The tight tolerances, multiple bearings and high speed operation make them less suited to high viscosity fluids or any abrasive medium or feed with entrained solids.

A global leader in hydraulic pump design and manufacturing was approached by SPIROLShims regarding their use of shims. They were interested in changing their existing program with the goals of improving quality, having consistent supply and reducing overall cost.

Hydraulic pumps serve virtually every industry in manufacturing and technology applications such as chemical plants, automotive engineering, marine / offshore projects, railway engineering, civil water facilities and many other industrial applications.

The precision steel shims used in hydraulic pumps are engineered to be durable and meet extremely tight tolerances. Shims account for the variation in the pumps components for precise fit and proper bearing load.

Shims used in hydraulic pumps are manufactured to precise hardness specifications and dimensional tolerances to ensure proper long lasting functionality.

Thickness tolerance (to .0004 inch), flatness and parallelism are important for the correct shim selection based on the assembly measurements. Precise fit is needed for optimum pump functionality and durability.

The rough blanks still needed be ground to specified thickness. This was done on-site at the pump manufacturer. The grind operation was not part of their core business, was costly and slowed down the assembly lines. The hydraulic pump manufacturer wanted to remove grind operations from their facility.

The SPIROL Shims sales engineer worked closely with the pump manufacturer to determine the part"s requirements, program scope and the goals of improving quality and availability while reducing overall program costs.  After careful review and project development, SPIROL Shims was able to offer a program that addressed all of their goals.

The SPIROL proposal for the large shim program allows the pump manufacturer to focus on its core business of hydraulic pump production and not managing a time consuming shim program.

In summary, SPIROL Shims is now producing the entire package of shims for the hydraulic pump manufacturer. The shims are manufactured as complete parts with superior quality, improved availability and at a significant costs savings.
