The type of hydraulic pump you need depends on a variety of factors, including, but not limited to, the type of hydraulic fluid used in your machinery, operating pressure, application speed, and flow rate requirements.

Two of the most common pumps used in hydraulic equipment are piston pumps and gear pumps. This article will highlight everything you need to know about each pump, including its common uses and benefits.

A piston pump is a positive displacement pump that uses reciprocating motion to create rotation along an axis. Some piston pumps have variable displacement, while others have a fixed displacement design.

A hydraulic piston pump is capable of the highest pressure ratings and is commonly used to power heavy-duty lifts, presses, shovels, and other components.

The downside of piston pumps is that they are often more expensive (especially when compared to gear pumps). Still, their improved efficiency often makes them a better investment for long-term production.

Gear pumps use gears or cogs to transfer fluids. The cogs are tightly aligned to create suction as they draw liquid in and discharge it. The gears can be internal or external, depending on the application. Gear pumps are also positive displacement pumps, but they are always fixed displacement, so you would need separate pumps or valves to control the amount of displacement.

Gear pumps are known for being reliable and durable when they are well-maintained. Compared to piston pumps, they also don’t require as much maintenance and are typically more affordable. However, these pumps usually max out at 3000 PSI. While this is enough pressure to power some machinery, it may not have the power to operate large presses and other industrial equipment. A gear-style pump also lacks the ability to vary the displacement of your system.

Gear pumps are often used in low-pressure applications where dispensing high-viscosity liquids is required. They are typically used in the food and beverage, pulp and paper, and oil/chemical industries.

The primary difference between a gear pump and a piston pump is how they are designed. While both pumps need hydraulic fluid to generate mechanical power, a piston pump uses a piston to move liquid throughout the pump valves, while a gear pump uses cogs to move fluid throughout the pump.

Gear pumps are affordable for low-pressure applications (35 to 200 bar or 507 to 2900 PSI), while piston pumps are more efficient options for high-pressure applications. A piston pump is also a better option if you’re looking for a pump with a higher discharge rate. Lastly, a piston pump will provide the most efficiency if your application is high-speed.

You’ve heard about the difference between a vane pump and a gear pump, but not exactly know what it means. Well, this article is here to clear things up. Read on to learn more about the differences between these two types of pumps:

Gear pumps are better suited for high-pressure applications, while vanes can handle lower pressure. However, vane pumps are also used in higher-pressure applications as well.

A gear pump uses gears and a vane pump uses vanes to increase the flow rate of the liquid. A gear pump is built with a series of gears that spin around their axis at different rates. This creates a number of different patterns that allow for more fluid to pass through each gear than just one. The result is an increased flow rate for each gear because it has access to more volume.

Vane pumps use vanes which move toward and away from each other in order to create a larger area for fluid flow through. The overall design of a vane pump is similar to that of a gear pump but instead of using gears, it uses vanes which move toward and away from each other in order to create a larger area for fluid flow through.

Vane pumps have a unique design that allows them to pump more viscous liquids, such as honey, molasses and oil. They are also able to handle much higher flow rates than other types of pumps. Vane pumps are ideal for applications that require high-pressure or high-viscosity liquid pumping. In addition, they’re easier to clean than other types of pumps because they don’t need lubrication or seals.

In general, vane pumps have a larger diameter than gear pumps, but they have the same overall volume as a gear pump. This means they’ll be able to handle more volume at higher speeds and pressures than a gear pump would be able to do.

Vane pumps are typically more efficient at operating at low speeds because they rely on the rotation of their vanes rather than gears or other mechanisms that can reduce efficiency over time.

This is because the gear pump’s shaft is offset to allow it to be mounted in a larger diameter housing, which reduces the noise generated by the motor. The smaller diameter housing of a vane pump can cause it to vibrate excessively, thereby adding noise. However, vane pumps are also quieter than other kinds of pumps, including impeller pumps and centrifugal pumps.

Vane pumps are often used in applications where they need to be extremely quiet or where there are other concerns about vibration or humming caused by other types of motors or machinery. Vane pumps are also used in industrial applications where high pressure is required and there is no need for continuous power supply like that provided by a gear pump.

Gear pumps are typically used as a source of power for larger systems and for applications that require a high flow rate. They have many advantages, such as being able to deliver a high head (pressure) for a low flow rate. Because of their high efficiency, they are also used in the production of concrete, where they deliver a high head at low flow rates.

Vane pumps can produce much higher pressure than gear pumps. They do this by using a large diameter shaft with multiple vanes which rotate around it. This makes it possible to turn the pump shaft faster than with a gear pump and therefore achieve greater pumping speed without sacrificing efficiency.

Gear pumps are more efficient because they rotate at a constant speed, while vane pumps are not. When you put a gear pump in your system and it starts to spin up, it won’t increase the flow until it reaches its maximum rotational speed (which is slower than an impeller).

Vane pumps have a fixed volumetric efficiency that cannot be changed from the manufacturer’s spec. This means that as you increase the flow through your system, you may get less throughput per revolution of the pump.

Gear pumps are also more efficient, which means they can produce the same amount of horsepower at a lower cost. Gear pumps have advantages over vane pumps in that they can be used for both high- and low-pressure applications, and their construction is more durable than vane pumps. Vane pumps are generally more expensive, but they do have some advantages over gear pumps, such as being able to work at higher pressures.

Although they were not commonly used in the petrochemical industry until recently, they are now used extensively in this area. In addition to the traditional applications, vane pumps are also being applied as a motor for windmills and other machines that require a high output torque at low speed.

Vane pumps come in different forms such as axial piston vane pumps, radial piston vane pumps, centrifugal vane pumps, etc. The most common types of vane pumps are axial piston pump and radial piston pump.

Axial Piston Pump: This type of pump is used for water supply or waste water applications where the discharge pressure is relatively high and flow rate is relatively low. It consists of an enclosed rotor with a number of vanes arranged parallel to it. The arrangement of these vanes provides an efficient distribution of flow into the discharge line while maintaining its velocity in a vertical direction by using countercurrent flow technique.

A gear pump is a device used to transfer fluid from one place to another using a rotating shaft. They are designed to operate at low speeds and high pressures. A gear pump does not use a vane pump, but rather gear wheels or disc wheels to turn the shaft. Vane pumps are better for stationary applications, but gear pumps are best for portable equipment.

A vane pump has two parts: the impeller and the casing. The impeller is mounted on the shaft of the pump and has two vanes that spin around it. This type of pump has flow control by means of vanes that change in size as they rotate. A vane pump can work at any rotational speed, but it will deliver more power at higher speeds because its flow rate is greatest at these higher speeds.

Gear pumps have only one moving part, which is the shaft itself. We haven’t added any other internal parts to affect its operation; thus, you can spin as fast as you like if there aren’t any complications.

This blog post hopes to provide a brief, simple explanation of the difference between geared and vane pumps, and it was written with the hope that you can use this information as a guide to help you in the future. Happy reading!

With so many choices available for industrial pumps, the selection process often comes down to carefully evaluating the needs of the industry and choosing a pump that will be efficient and reliable in a specific application.

The case is no different when selecting sliding vane and rotary gear pumps. While both are types of positive displacement pumps, there are nuances that make one or the other better suited for a particular application.

A sliding vane pump uses a rotor with sliding vanes that creates suction between the vanes when the rotor rotates, thereby drawing the fluid behind each vane. The rotation carries the fluid between the inlet and the outlet. This type of construction allows sliding pumps to deliver constant flow under different pressure conditions.

While both sliding and rotary gear pumps are considered positive displacement pumps, the differences in their construction give them unique characteristics. Let us explore some of them in detail.

Sliding vane pumps have average performance in pumping viscous fluids. This is mainly because viscous fluids cannot easily enter the cavities formed within the pump. For pumping high viscous fluids, the speed of the sliding vane pumps must be lowered significantly.

Gear pumps, especially internal gear pumps, are great at handling viscous fluids. Their ability to work at slow speeds with minimal inlet pressure makes them ideal for viscous fluids.

Sliding vane pumps excel in pumping thin fluids. Their design makes it easier for the low viscosity fluids to enter the cavities. Therefore, the pump exhibits good suction capability.

Both gear and sliding vane pumps create pumping action with tight clearances. Pumping solids can significantly affect these clearances in a negative way, and the pumps can even lose their efficiency drastically.

Sliding vane pumps are better at handling wear. Since the vanes can be easily adjusted, these pumps are often referred to as wear adjusting pumps, where the pump automatically adjusts for the wear to maintain efficiency throughout its lifetime. If the wear becomes excessive to the degree that the pump cannot self-compensate, you can easily swap out the vanes.

Gear pumps wear at the meshing surface. A high degree of wear can introduce play between the meshing surfaces of the gears, causing the pump to lose its efficiency.

While both sliding vane pumps and rotary gear pumps have pros and cons, choosing between them depends largely on your specific fluid transport application. With over 40 application specialists on staff, Hayes Pump can help you find the right pumps for your requirements and have the setup running in no time.

Hydraulic pumps convert mechanical energy into fluid power energy. All hydraulic pumps are positive displacement which means the outlet flow is sealed from the inlet flow. A small amount of fluid is designed to leak internally to lubricate and cool the internal components of the pump. The only function of the pump is to produce flow in a system. Bailey International, LLC provides a wide range of pumps and accessories including clutch pumps, dump, gear, jaw couplers, mounting brackets, pistons, PTO, vane and two stage pumps.

A gear pump is a type of positive displacement (PD) pump. It moves a fluid by repeatedly enclosing a fixed volume using interlocking cogs or gears, transferring it mechanically using a cyclic pumping action. It delivers a smooth pulse-free flow proportional to the rotational speed of its gears.

Gear pumps use the actions of rotating cogs or gears to transfer fluids. The rotating element develops a liquid seal with the pump casing and creates suction at the pump inlet. Fluid, drawn into the pump, is enclosed within the cavities of its rotating gears and transferred to the discharge. There are two basic designs of gear pump: external and internal(Figure 1).

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).

An internal gear pump operates on the same principle but the two interlocking gears are of different sizes with one rotating inside the other. The larger gear (the rotor) is an internal gear i.e. it has the teeth projecting on the inside. Within this is a smaller external gear (the idler –only the rotor is driven) mounted off-centre. This is designed to interlock with the rotor such that the gear teeth engage at one point. A pinion and bushing attached to the pump casing holds the idler in position. A fixed crescent-shaped partition or spacer fills the void created by the off-centre mounting position of the idler and acts as a seal between the inlet and outlet ports.

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 and partition.

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. Gear pumps are particularly suited for pumping oils and other high viscosity fluids.

Of the two designs, external gear pumps are capable of sustaining higher pressures (up to 3000 psi) and flow rates because of the more rigid shaft support and closer tolerances. Internal gear pumps have better suction capabilities and are suited to high viscosity fluids, although they have a useful operating range from 1cP to over 1,000,000cP. Since output is directly proportional to rotational speed, gear pumps are commonly used for metering and blending operations. 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 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 hydraulic 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.

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. However, some designs of gear pumps, particularly internal variants, allow the handling of solids. External gear pumps have four bearings in the pumped medium, and tight tolerances, so are less suited to handling abrasive fluids. 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 clearance 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.

Internal gear pumps, operating at low speed, are generally preferred for shear-sensitive liquids such as foodstuffs, paint and soaps. The higher speeds and lower clearances of external gear designs make them unsuitable for these applications. Internal gear pumps are also preferred when hygiene is important because of their mechanical simplicity and the fact that they are easy to strip down, clean and reassemble.

Gear pumps are commonly used for pumping high viscosity fluids such as oil, paints, resins or foodstuffs. They are preferred in any application where accurate dosing or high pressure output is required. 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.

A gear pump moves a fluid by repeatedly enclosing a fixed volume within interlocking cogs or gears, transferring it mechanically to deliver a smooth pulse-free flow proportional to the rotational speed of its gears. There are two basic types: external and internal. An external gear pump consists of two identical, interlocking gears supported by separate shafts. An internal gear pump has two interlocking gears of different sizes with one rotating inside the other.

Gear pumps are commonly used for pumping high viscosity fluids such as oil, paints, resins or foodstuffs. They are also preferred in applications where accurate dosing or high pressure output is required. External gear pumps are capable of sustaining higher pressures (up to 7500 psi) whereas internal gear pumps have better suction capabilities and are more suited to high viscosity and shear-sensitive fluids.
