HPV Series Closed Axial Piston Pumps

Variable Displacement Axial Piston Pumps for Closed-Circuit Systems

The Highland HPV Series is a range of hydraulic transmission pumps that use closed-circuit axial piston variable displacement technology.

The series covers rated displacements from 30 to 130 mL/rev, plus multiple control modes, rotation directions, input shaft configurations and auxiliary mounting flange options.

Series-level technical data includes a rated speed of 2500 r/min, minimum continuous operating speed of 500 r/min, rated working pressure of 35 MPa, continuous working pressure of 30 MPa, and maximum instantaneous working pressure of 42 MPa.

The HPV Series can be configured according to displacement, control mode, rotation direction, shaft interface and mounting parameters. Final configuration should be confirmed with reference to the application hydraulic circuit and installation dimensions.

HPV Series Technical Overview

The supplied technical drawing also contains a configuration-level technical requirement showing 30 MPa rated working pressure. The applicable pressure rating should therefore be confirmed against the final pump configuration and engineering documentation before integration.

Highland Tandem hydraulic pumps basic information: 

Highland hydraulic could produce tandem hydraulic pumps, treble pump and quadruple pump.

Highland tandem hydraulic pumps are axial piston variable displacement pumps, and have swash plate structure design, and are intended for closed circuit hydraulic system applications. The flow rate is proportional to the pump input speed and displacement. The latter is infinitely adjustable between zero and maximum displacement. Flow direction is reversed by tilting the swash plate to the opposite side of the neutral (zero displacement) position.

Highland Tandem hydraulic pumps main features:

Variable displacement axial piston pumps

Swash plate structure design

Closed circuit hydraulic system applications

Wide range of displacement

CW or CCW, left or right rotation direction

Compact structure

High efficiency, high pressure

Multiple control modes

Hydraulic oil notice of Highland tandem 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 Scope

The HPV Series is documented as a closed-circuit axial piston pump series.

An agricultural machinery reference for the HPV130-MA-R-23 configuration, specifically a potato harvester in Kyrgyzstan, is provided by the supplied project documentation.

Potential application suitability should be determined from the actual hydraulic system requirements rather than from application category alone. Important selection factors include displacement, pressure, speed, control mode, rotation, shaft interface and mounting configuration.
