Application / Project Evidence

Variable Piston Pump Project for Concrete Mixer Trucks

The HPV50-MA-R-21 is documented in a hydraulic pump project for a concrete mixer truck application in Malaysia.

Project details:

• Project: Variable Piston Pump for Malaysia
• Manufacturer: Shandong Highland Hydraulic Seiko Co., Ltd.
• Pump model: HPV50-MA-R-21
• Quantity: 50 units
• Application: Concrete Mixer Trucks
• Hydraulic circuit: Closed Circuit Hydraulic System
• Max. displacement: 50 mL/rev
• Rated working pressure: 35 MPa
• Max. transient pressure: 42 MPa
• Continuous working pressure: 30 MPa
• Max. continuous working speed: 3500 r/min

Supporting the project documentation are product technical parameters, engineering drawings and a factory performance test report for the HPV50-MA-R-21.

This project reference demonstrates the documented application of the HPV50 series in concrete mixer truck equipment, and provides application-specific technical evidence for customers evaluating the pump for similar hydraulic systems.

Factory Performance Testing

A factory performance test is carried out on the HPV50-MA-R-21 closed-loop axial piston pump prior to shipment, checking its main operating behaviour under controlled conditions.

This unit was tested on September 14, 2026 at 31.4°C; its rated displacement was 50 mL/rev, rated pressure 35 MPa and maximum pressure 42 MPa.

Measurements recorded during the test comprised pump speed, outlet pressure, flow, displacement, input torque, input power, output power, overall and volumetric efficiency. The report identifies the model as HPV50-MA-R-21 and includes a unique component number for traceability.

Such testing supplies product-specific operating data to application engineers and customers, beyond nominal catalogue specifications alone.

Recorded Test Data

The table below lists the values measured on the factory test stand for the HPV50-MA-R-21 hydraulic pump.

Test conditions:

• Temperature 31.4 °C
• Rated displacement 50 mL/rev
• Rated pressure 35 MPa
• Maximum pressure 42 MPa
• Maximum speed 3,500 r/min
• Charge pressure 1.6 MPa
• Charge flow 12.4 L/min

These figures come from the factory test report of HPV50-MA-R-21, component No. 02609140203023.

Engineering Drawing

Engineering drawings with full dimensions are supplied for the HPV50-MA-R-21 closed-loop axial piston pump.

They provide the dimensional and interface information necessary for system integration: overall mounting dimensions, shaft and spline specifications, hydraulic ports, leakage ports, pressure test ports, control-handle dimensions and control positions.

The drawings additionally specify the rotation direction and the pressure-port configuration for both clockwise and counterclockwise operation.

Key interface data include:

• HPV50-MA-R-21 product model
• 50 mL/rev rated displacement
• Ports A and B (main)
• Ports L1 and L2 (leakage)
