Highland agricultural hydraulic pumps usage: 

With the improvement of science and technology, nowadays agricultural hydraulics are becoming more and more common, our hydraulic pumps motors could make hydraulic farming easy, which are used for kinds of agricultural equipment, such as combine harvesters, grape machinery, tractors, sprayers, track loaders, forage harvesters etc farming machinery.

Hydraulic oil notice of Highland agricultural hydraulic pumps: 

The higher the cleanliness of the hydraulic oil, the longer the service life of the hydraulic pump.

Hydraulic oil:

Generally speaking, the replacement time of hydraulic oil of sealed oil tank system is 2000hours. If the hydraulic oil is contaminated or other outside material bears abnormal running condition, the hydraulic oil should be changed often.

Hydraulic oil in the open oil tank system should be changed every 500hours. For different vehicle, the measures should determined by specific design and operational experience.

Application / Project Evidence

Variable Piston Pump Project for Concrete Mixer Trucks

The HPV50-MA-R-21 has been 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
• Maximum Displacement: 50 mL/rev
• Rated Working Pressure: 35 MPa
• Maximum Transient Pressure: 42 MPa
• Continuous Working Pressure: 30 MPa
• Maximum Continuous Working Speed: 3500 r/min

The project documentation is supported by 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

To confirm key operating characteristics under controlled conditions, the HPV50-MA-R-21 closed-loop axial piston pump is performance-tested before it leaves the factory.

For the tested pump, the factory test took place on 14 September 2026 at a test temperature of 31.4°C. Rated displacement was 50 mL/rev, rated pressure 35 MPa and maximum pressure 42 MPa.

The recorded procedure covered pump speed, outlet pressure, flow rate, displacement, input torque, input power, output power, overall efficiency and volumetric efficiency. A unique component number and the component model HPV50-MA-R-21 are stated in the report for traceability.

Factory performance testing therefore provides application engineers and customers with product-specific operating data, rather than relying only on nominal catalogue specifications.

Recorded Test Data

The results captured during factory performance testing of the HPV50-MA-R-21 pump are shown below.

Conditions of the test:

• Test temperature — 31.4°C
• Rated displacement — 50 mL/rev
• Rated pressure — 35 MPa
• Max pressure — 42 MPa
• Max speed — 3500 r/min
• Charge pressure — 1.6 MPa
• Charge flow — 12.4 L/min

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)
• Port S (oil suction)
• Port M (pressure/test)
• Control: Manual / EP servo / Hydraulic servo
• Input shaft spline configuration by model
• SAE-related control and shaft dimensions

Hydraulic system designers can use these drawings to check mounting, shaft connection, port configuration and installation requirements before ordering.

Quality Control & Inspection

Before shipment, quality control of the HPV50-MA-R-21 covers product configuration, dimensional requirements and hydraulic performance.

The factory test record for the tested unit states the manufacturer, component model, component number, rated displacement, rated pressure, maximum pressure and test temperature; performance inspection covers operating speed, pressure, flow, displacement, input torque, input power, output power, overall efficiency and volumetric efficiency.

Dimensional and interface information for the pump body, hydraulic ports, leakage ports, shaft spline and control mechanism is provided in the engineering documentation.

Together, the configuration records, engineering documentation and recorded performance data give traceable technical evidence for the hydraulic pump supplied.
