Axial Piston Pumps for Medium to Heavy-Duty Hydraulic Systems
Techknow Engineering Enterprise is an axial piston pump supplier for industrial plants, OEMs and mobile equipment users across India. We supply fixed and variable displacement axial piston pumps in swash-plate and bent-axis designs, selected to match your pressure, flow, control and mounting requirements.
An axial piston pump combines high pressure capability with high efficiency, and its displacement can be made adjustable. That makes it the standard choice for presses, injection moulding machines, machine tools, steel plant hydraulics and hydrostatic drives. We are an Authorized HYDAC Distributor and also supply axial piston pumps from Rexroth, Parker, Yuken and Eaton-Vickers.
Tell us what the pump has to do, or send the nameplate of the pump you are replacing, and our team will confirm a suitable pump.
How an Axial Piston Pump Works
Pistons parallel to the shaft, stroke set by an angle.
In this design, a ring of pistons sits in a cylinder block that turns with the drive shaft. The pistons run parallel to the shaft and slide against an inclined surface, so each piston completes one suction and one delivery stroke per revolution. The angle of that surface sets the stroke length and therefore the displacement.
Swash-Plate and Bent-Axis Designs
Swash-plate design
The pistons bear on an inclined swash plate. Tilting the swash plate changes the stroke, so swash-plate pumps are the most common basis for a variable displacement axial piston pump with pressure, load-sensing or power control. They are compact and allow a through-drive for a second pump.
Bent-axis design
The cylinder block is set at an angle to the drive shaft. Bent-axis pumps handle high pressures and speeds with high efficiency, and are widely used as fixed displacement pumps and motors in mobile and industrial drives.
Fixed and Variable Displacement Axial Piston Pumps
Choose the configuration that matches how your machine uses flow.
Fixed Displacement Axial Piston Pump
Delivers a constant volume per revolution — up to 400 bar with flow from 27 to 950 lpm, depending on version. Best suited to open circuits where demand is steady, or where flow is controlled by valves downstream.
Variable Displacement Axial Piston Pump
Adjusts the swash-plate angle to vary flow — up to 500 bar with flow from 32 to 1000 lpm, depending on version. A variable displacement axial piston pump can be used in both open and closed circuits and reduces heat and power loss at part load. Compare variable displacement pumps.
Control Options for Axial Piston Pumps
The control decides how the pump responds to the load.
Most variable axial piston pumps are ordered with a control that regulates displacement automatically. The right control keeps pressure stable, avoids wasting flow over a relief valve, and lowers oil temperature.
Common Controls We Supply
- Pressure-constant (compensator): holds a set pressure and reduces flow when the limit is reached
- Variable pressure: pressure setting adjusted remotely to suit each machine step
- Un-load: reduces pressure and power when the machine is idle
- Load-sensing: delivers only the flow and pressure the actuator needs, plus a small margin
- Power / torque limit: keeps input power within the motor or engine rating, where available on the selected series
Tell us the machine cycle and we will suggest the control, or match the control code on your existing pump.

Choosing an Axial Piston Pump Supplier and the Right Pump
Correct selection and clean oil decide service life.
Axial pumps are precision components. Working with an axial piston pump supplier that checks duty, circuit and commissioning conditions before dispatch avoids most early failures and costly rework on the machine.

FAQ'S
An axial piston pump is a positive-displacement hydraulic pump in which pistons run parallel to the drive shaft. The angle of a swash plate or bent-axis block sets the stroke and therefore the displacement.
It is a pump whose swash-plate angle can be changed while running, so flow adjusts to demand. Variable versions we supply reach up to 500 bar and 32–1000 lpm, depending on version, and can be used in open and closed circuits.
In a swash-plate pump the pistons bear on an inclined plate, which is easy to tilt for variable control. In a bent-axis pump the whole cylinder block is angled to the shaft, giving high efficiency at high pressure and speed.
We are an Authorized HYDAC Distributor and also supply axial piston pumps from Rexroth, Parker, Yuken and Eaton-Vickers. Send your model code to check availability.
Yes. Share the nameplate type code, mounting, shaft and control details and we will identify the same pump or a suitable alternative.
Case drain flow carries internal leakage back to tank. A restricted drain line can damage seals, and rising drain flow over time is an early sign of wear inside the pump.
