Product Description
Highland Variable Displacement Piston Type Axial Flow Hydraulic Pump
Highland Variable Displacement Piston Type Hydraulic Pump introduction:
Highland Hydraulic pump has high volumetric efficiency, small leakage and variable displacement piston type, which can work under high pressure, mostly used in high power hydraulic system, with complex structure, high material and processing accuracy, high cleanliness of oil requirements. By designing and manufacturing static hydraulic transmission, we can provide axial flow hydraulic pump and hydraulic motor assembly and hydraulic system with high quality, high-performance parameters.
Highland Variable Displacement Piston Type Hydraulic Pump features:
Variable displacement piston type hydraulic piston pump is well engineered and easy to handle.
Bearings of axial flow piston hydraulic pumps are all tapered roller bearing, which can load heavy external axial forces.
When hydraulic pumps operated mechanically, the servo displacement can control variable displacement and keep the angle of swash plate and pump displacement.

Test Data & Performance Verification
HPV90 Performance Verification
The available factory test record provides measured performance data rather than relying only on catalog specifications. During testing, the HPV90-MA-R-23 was evaluated at different pressure levels while recording speed, flow, displacement, torque, input power, output power, overall efficiency and volumetric efficiency.
At approximately 30.3 MPa, the recorded flow was 103.7 L/min in one test sequence and 102.8 L/min in the second sequence, with volumetric efficiency recorded at 93.8% and 93.0%, respectively.
Performance data shown on this page is taken from the supplied factory test record and represents the documented test conditions. Actual operating performance may vary depending on hydraulic circuit configuration, fluid conditions, temperature and application conditions.
