Hydraulic Piston Pumps are precision-engineered components designed to deliver high pressure, consistent flow, and superior efficiency in hydraulic systems. Compared with gear and vane pumps, Piston Pump Hydraulic systems achieve higher power density, precise control, and long-term reliability — making them ideal for heavy-duty applications such as industrial machinery, construction equipment, and marine systems.

As one of the professional Piston Pump Manufacturers, we provide a wide range of Pump Piston Hydraulic products, including both fixed and variable displacement types, to meet the diverse requirements of your hydraulic systems.

What Is a Hydraulic Piston Pump?

A Piston Hydraulic Pump is a type of positive displacement pump that uses multiple pistons reciprocating inside a cylinder block to generate flow.
These pumps convert mechanical energy into hydraulic energy by moving pressurized fluid through a closed system.
They are mainly classified into two types:

• Axial Piston Pump — Pistons are arranged parallel to the drive shaft.

• Radial Piston Pump (Radial Plunger Pump) — Pistons are arranged radially around the drive shaft.

Hydraulic Piston Pumps are known for:

• High pressure capability (up to 700 bar)

• Excellent volumetric and mechanical efficiency

• Adjustable displacement for energy savings

• Compact design and smooth operation

Main Advantages of Piston Pump Hydraulic Systems

1. High Pressure Output
   Piston Pump Hydraulic systems operate efficiently at high pressure, suitable for heavy-load equipment and industrial applications.

2. Variable Displacement Control
   Many models support adjustable displacement, allowing precise flow control and better energy efficiency.

3. High Efficiency and Low Leakage
   Due to tight internal tolerances, Hydraulic Piston Pumps maintain over 90% volumetric efficiency.

4. Long Service Life
   High-grade materials and advanced manufacturing ensure excellent wear resistance and long operating life.

5. Smooth and Quiet Operation
   Compared with gear pumps, piston pumps offer smoother operation and reduced noise.
