HY Series Axial Piston Pump | HY80, HY90, HY125, HY140 | 31.5MPa Variable Pump

HY Series Heavy-Duty Axial Piston Variable Pump

Product Overview: The HY series represents a range of high-performance axial piston variable pumps specifically engineered for heavy-duty industrial environments, renowned for exceptional volumetric efficiency and long-term stability under high pressure. Spanning displacements from 80cc (HY80) to 140cc (HY140), this series supports a rated operating pressure of up to 31.5 MPa. Featuring the advanced P01 Pressure Compensator control, the pump automatically modulates displacement based on load demand, de-stroking once preset pressure is reached to drastically reduce energy consumption and heat generation.

Key Technical Advantages:

• P01 Intelligent Pressure Compensation: Models such as HY80P01 and HY125P01 are equipped with high-sensitivity pressure compensation. Once the system hits the preset pressure level, the pump automatically reduces its swashplate angle to minimum flow, maintaining pressure while eliminating reactive power loss.

• Heavy-Duty High-Pressure Performance: Constructed with reinforced rotating groups and high-strength ductile iron housing. With a rated pressure of 31.5 MPa (315 Bar) and peaks up to 40 MPa, it ensures reliable performance even under shock loads in shearing or extrusion applications.

• Flexible Rotation Configurations (RP/LP):

  • RP (Right-hand/Clockwise): Compatible with most standard motor drive configurations.

  • LP (Left-hand/Counter-clockwise): Designed for specialized layouts or tandem pump systems requiring reverse rotation.

• Low Noise & Extended Service Life: The optimized valve plate design effectively suppresses pressure pulsations, reducing mechanical vibration and noise—perfect for indoor factory environments with strict noise regulations.
