Hydraulic piston pumps move fluids throughout professional equipment and industrial machinery. They’re known for their high efficiency and are commonly used in high-pressure applications.

There are also two major types of hydraulic piston pumps: axial and radial; both can have fixed or variable displacement; fixed displacement means that the pump is delivering the same amount of liquid or gas each time, while variable means that the amount of gas or liquid delivered may be different each time. Although both are considered piston pumps, each one operates differently.

An axial piston pump features four major components: a shaft, swashplate or bent axis, cylinder block, and valve plate. The cylinder block houses the piston pumps, which are laid out cyclically around the drive shaft’s axis (thus why it is named anaxialpiston pump).

The pistons in the cylinder block pump up and down as the drive shaft rotates. The piston’s stroke will vary depending on how it is angled in the swashplate or bent axis. As the pistons move in one direction, they are connected to a suction line, and when they move in the opposite direction, they connect to a discharge channel, allowing a continuous flow of fluid.

The design of a radial piston pump is significantly different from an axial pump. The radial piston pump consists of a cylinder block, rotating camshaft, and pistons. The pistons are arranged around the cylinder block in a radial pattern and diverge from the camshaft like rays. The rotation of the cam causes the pistons to change from suction to discharge and vice versa.

In general, choosing a hydraulic pump requires an application evaluation. You’ll need to know pressure requirements, desired flow rate, speed, horsepower, and the type of fluid the pump will be dispersing.

Radial piston pumps can usually handle all fluids, including mineral oil and water-glycol hydraulic fluid, while axial piston pumps are preferred for extremely high-pressure applications.

Although piston pumps are highly efficient and reliable, contamination, over-pressurization, and inlet blockages can cause the pump to fail. If and when this happens, you’ll need to replace your pump as soon as possible.

When choosing a replacement pump, you’ll have to choose between a direct OEM replacement and a remanufactured pump. Unfortunately, direct OEM replacement pumps and services can be a significant investment. Additionally, if you have outdated equipment, you may not be able to find thepump partsneeded to restore your equipment.

If you’re looking for a quick and relatively inexpensive solution, a remanufactured pump is your best choice. However, if time and money aren’t an issue, a direct OEM replacement will most likely be the best option if the manufacturer hasn’t discontinued the pump.

Do you need help finding the right piston pump? Turn to Panagon Systems. Founded over 25 years ago, we’re an industry-leading remanufacturer of hydraulic piston pumps and motors. We specialize in remanufacturing pumps from brands like Vickers/Eaton, Rexroth, and Caterpillar, and we also carry. All pumps and motors are remanufactured in-house in the United States, guaranteed to meet OEM specifications, and are backed by a one-year warranty.

Piston design - Solid, hollow, or with piston rings. The design and weight of the pistons will have a major effect on pump efficiency. The Parker F11 design with its lightweight head and retained balls can reach significantly higher speeds than swashplate pumps with their longer, heavier pistons.

Some pumps and motors can run over-centre, which means they can provide flow or rotate their drive shaft in both directions. These are commonly used in closed circuit, mobile vehicle drives systems.

Bent axis designs tend to have much heavier duty shaft bearings than swashplate pumps. This is because they are more commonly used as motor drive units and have to take the wheel loads against their shaft. Swashplate pumps, on the other hand, tend to be driven through flexible couplings that will remove any side loads, so the internal bearing is sized just to take the internal loads from the dynamic and pressure loading forces.

Noise level can be an issue with piston pumps. The noise is generated by the discontinuities in the flow e.g. as the pistons move forward and backward they create a pulsating flow that passes into the complete hydraulic system and vibrates or radiates from other components further down the circuit. This flow discontinuity is further complicated by the supply port which connects and disconnects each piston as it rotates. The timing of the opening and closing can create other, higher frequency flow discontinuities. Often different timing plates are available for different operating conditions e.g. fixed speed or variable speed applications.

Case leakage line pressures are critical for controlling the pressure balance of the slipper against the suction pressure. Care should be taken with some pump controllers as the valves exhaust into the pump casing and can create dangerous pressure spikes. Make sure case drain lines are sufficiently sized. One possible solution may be to use a more compliant, clear plastic hose for the case leakage line which will have the effect of damping out these peaks before damage the slippers. Case leakage line temperatures are also a good way of monitoring the health of the pump as discussed in the vane pump section.

If you are in doubt about the most appropriate pump to use in your application then always talk to manufacture or distributor who should be able to offer the most appropriate pump range and advise the expected service life.

An irregular performance of a mechanical-type constant power regulator is considered. In order to find the cause of an irregular discharge flow at the cut-off pressure area, modeling and numerical simulations are performed to observe dynamic behavior of internal parts of the constant power regulator system for a swashplate-type axial piston pump. The commercial numerical simulation software AMESim is applied to model the mechanical-type regulator with hydraulic pump and simulate the performance of it. The validity of the simulation model of the constant power regulator system is verified by comparing simulation results with experiments. In order to find the cause of the irregular performance of the mechanical-type constant power regulator system, the behavior of main components such as the spool, sleeve, and counterbalance piston is investigated using computer simulation. The shape modification of the counterbalance piston is proposed to improve the undesirable performance of the mechanical-type constant power regulator. The performance improvement is verified by computer simulation using AMESim software.

The pressure regulators of swashplate-type variable displacement axial piston pumps (VDAPP) control the swivel angle, which changes the amount of flow rate to hydraulic circuits. The pressure regulator is operating in accordance with the dynamic response of the discharge pressure, and it supplies pilot flow rate to the control piston which regulates the swivel angle of swashplate. The pressure regulator is mainly divided into the three types depending on the operating method, that is, a flat cut-off type, a differential cut-off type, and a constant power type.

The pressure regulators are usually used to save energy of hydraulic systems in the industrial field. As the hydraulic power unit used for movable equipment has increased, the pressure regulators have been applied in such systems in order to protect prime mover. Most movable hydraulic power unit consist of motor, pumps and reservoir (MPR). An overload of the pump can cause damage to the electric motor and its circuits under a variety of load conditions. To avoid these problems, power regulation of the pump is needed in order to respond to wide varieties of loads without exceeding the maximum power range of the prime mover. In this study, we applied the constant power regulator to the VDAPP so that the angle of the swashplate is automatically decreased according to an increase of the load pressure.

Recently, electronic regulators have been studied and commercialized [1–4]. However, the mechanical regulators are mainly applied in the industrial field because a proportional reducing pressure valve which is used as main part of the electronic regulator has relatively poor durability than mechanical regulator. In recently developed hydraulic regulator systems, both the electrical and mechanical regulators are applied to hydraulic regulator system. In those hydraulic regulator systems, the mechanical regulator is used as emergency equipment so that it only works when the electronic regulator fails. Due to the relatively exceptional durability, the mechanical regulator system is especially adopted to construction equipment and combat vehicles, which are used for long periods in poor conditions.

A schematic diagram of a swash plate VDAPP with a constant power regulator is shown in Figure 1. Figure 2 represent hydraulic circuit of the constant power regulator system. The constant power regulator system consists of five parts, that is, a regulator assembly (A), a control cylinder assembly (B) which controls the angle of the swash plate, a counterbalance assembly (C), a swash plate (D), and a piston (E). As shown in Figure 3, the regulator assembly consists of a spool and sleeve. A flow area of the regulator system is determined by relative displacement between spool and sleeve. Figures 4 and 5 show the detailed structure of the control cylinder and counterbalance.

As shown in Figure 8, the swash plate is held in a certain swivel angle. In this area, the discharge pressure of the pump does not feed back into the control cylinder. This causes the swash plate to rotate in a maximum angular displacement. As a result, the pump can supply the maximum flow rate to a load system unless the discharge pressure of VDAPP is sufficiently increased to a certain level by a load. At the maximum flow rate section shown in Figure 9, the discharge flow rate cannot be feed into the control cylinder because the spool blocks the path of the sleeve.

In the constant power area shown in Figure 11, the spool is moved by the pilot pressure which is equal to load pressure, and the spool displacement makes the flow path to the control cylinder open. Then, the flow is supplied to the control cylinder. Therefore, the swivel angle is decreased, and the discharge flow rate of the pump is reduced. When the swivel angle is decreased, the sleeve reduces or blocks the flow to the control cylinder by the movement of the counterbalance piston. Therefore, the displacement of the control cylinder is adjusted according to the load variation. Consequently, the increase of the load pressure decreases the discharge flow rate of VDAPP, and that makes output power of VDAPP constant because the output power of VDAPP is determined by the product of load pressure and discharge flow rate.

As previously described, these characteristics of the pump-regulator assembly are determined by the interaction of the spool and sleeve. The pilot pressure generated by the load pressure of the system affects the spool.

In the VDAPP, the displacements of the control cylinder and the counterbalance piston are the same due to kinematic constraint. Therefore, (2) can be expressed as

where is the pressure in control cylinder, is the pressurized area of the control cylinder, is the mass of the control cylinder, is the viscous friction coefficient between the control cylinder and a sleeve, is the spring constant, is the initial displacement, is the displacement of control cylinder, and is the spring constant of the reaction spring for the sleeve of the constant power mechanical regulator.

where is the effective bulk modulus, is input flow rate to control cylinder, is output flow rate from control cylinder to reservoir, is the pressurized area of control cylinder, and is leakage coefficient of the control cylinder. At mechanical-type constant power regulators, the control flow varies according to the relative displacement between the spool and sleeve. Thus,

where is flow coefficient of orifice, and represent the orifice areas, is discharge pressure of the hydraulic pump, and is density of working fluid.

The displacement of the control cylinder, in (4), is determined by the resultant force on the swash plate as shown in Figure 15. The various forces are expressed in the form of a complex nonlinear model. In this study, in order to derive more accurate results, the VDAPP was also implemented using AMESim software.

A VDAPP with a mechanical regulator system was established using AMESim simulation software, which allows a very accurate implementation of the response of a nonlinear system. In the field of hydraulic component design, AMESim is widely used to optimization and performance improvement as a review of the actual system [5]. Figure 16 shows an AMESim diagram for the analysis of the system performance of an MPR system that consists of nine pistons.

The maximum swivel angle was set to 16°, which is the same as in the real component, and the exclusion volume was set to 11.6 cm3/rev. All parameters of the VDAPP are the actual design values used in the experimental equipment. The experimental equipment was modeled by considering the nonlinear behavior of the MPR pump system.

If the pump is composed of an odd number of pistons, the number of discharging pistons is determined by the rotation angle of the piston, which located at regular intervals on the plate as follows [11]:

Figure 17 shows the simulation result when the pump is driven at 4500 rpm under no-load condition. The discharge flow rate is the sum of the flow rate of each piston. The pulsation in flow rate is observed in simulation result as shown in Figure 17. This simulation results also show that the average value of the discharge flow rate 49.8 L/min is less than the theoretical one 52 L/min because the internal leakage through the gap between the piston and cylinder block is considered in computer simulation.

Figure 19 shows the hydraulic circuit of test rig for VDAPP. The angular velocity of the electric motor is regulated as 4500 rpm, and the load pressure is adjusted by adjustable relief valve which installed in the discharge line of the VDAPP. The discharge pressure is slowly increased during 45 seconds. The load pressure, the discharge flow rate, and the angular velocity and the torque of the electric motor are acquired by data acquisition board in real time.

Also, the displacement of the counterbalance piston in this simulation is shown in Figure 24. This result is in good agreement with the designed dimension of the real system.

On the other hand, an irregular fluctuation in displacement of the counterbalance piston causes pulsation of the discharge flow rate of the VDAPP. As discussed in previous section, the displacements of the control cylinder and the counterbalance piston are the same due to kinematic constraint. The pressures in the control cylinder affects to the displacement of it. The pressure in control cylinder is regulated by the balance of inlet/outlet flow rate in the volume of control cylinder. In addition, the inlet flow rate to the control cylinder is decided by the relative displacement between the spool and sleeve. Therefore, the discharge flow rate of the VDAPP is influenced by the relative displacement between the spool and sleeve in the constant power regulator.

Figure 25 shows the simulation results of the displacements of the spool and sleeve versus time. The simulation results in Figure 24 show that the displacement of the sleeve and spool is distinguished at about 35 seconds. This means that the orifice is open on this point, but counterbalance piston does not move until 44 seconds. This phenomenon can be explained as follows. Though the pilot flow rate is supplied to the control cylinder at about 35 seconds, the amount of inlet flow rate is less than that of leakage from control cylinder. Therefore, the pressure in control cylinder does not rise. The relative displacement between spool and sleeve becomes sufficiently larger at around 44 seconds. At this time, the inlet flow rate is larger than the leakage from control cylinder. Therefore, the pressure in control cylinder is rising and the counterbalance piston starts to move and a constant output control begins.

The fluctuation in displacement of the spool and sleeve remarkably appears in the pressure cut-off area from 56 to 58 seconds. At this period, the displacement of the counterbalance piston also oscillates, and the irregular discharge flow rate of the VDAPP is observed. This phenomenon seems to be accrued due to the discontinuous shape at the edge of the counterbalance piston because the reacting spring force of the sleeve acting on the counterbalance piston disappears immediately at this region.

In this study, the constant power mechanical regulator system with variable displacement axial piston pump is considered. The constant power mechanical regulator with VDAPP has a problem of pulsation in the discharge flow rate at the cut-off area. In order to solve the problem, the internal behavior of the constant power regulator with VDAPP is analyzed by modeling the system using the AMESim software. The theoretical analysis of constant power regulator is induced for precise modeling, and the internal dynamics of un-measurable components are studied. The validation of the simulation model is confirmed by comparing the simulation results with the experimental output of the real system. By analyzing the dynamics of the unmeasurable internal components, it is found that the irregular discharge flow rate is caused by the discontinuous shape at the edge of the counterbalance piston. Therefore, we proposed the rounded shape for the edge of the counterbalance piston. The effect of the redesigned shape is implemented by AMESim simulation, and the validation is verified by computer simulation. The future work is experimental confirmation of the redesigned shape.

The Inline variable displacement pump type V60N works according to the swash plate principle usually driven via the ancillary drive. It is intended for open circuit operation in mobile hydraulics. In optional thru shaft enables direct mounting of additional variable displacement pumps or a feed pump. These pumps are suited for a wide range of applications due to their low running noise and various pump controllers. The direct mounting at the gear box is either via a SAE-flange or a flange conforming ISO 7653. The flange area at the suction port enables optimized hose connection with little back pressure. Main benefits of these pumps are the sturdy design, the good performance/weight ratio and long service life due to oversized bearings.
