Highland 42Mpa Hydraulic Tandem Pumps For Agricultural Machinery Equipment

HPV Series Closed Axial Piston Pumps

Closed-Circuit Variable Displacement Axial Piston Pumps

The Highland HPV Series comprises a line of axial piston variable displacement pumps built for closed-circuit hydraulic transmission systems.

Rated displacements across the series range from 30 to 130 mL/rev, together with multiple control modes, rotation directions, input shaft configurations and auxiliary mounting flange options.

The series technical specifications include a rated speed of 2500 r/min, a minimum continuous operating speed of 500 r/min, a rated working pressure of 35 MPa, a continuous working pressure of 30 MPa, and a maximum instantaneous working pressure of 42 MPa.

Configuration of the HPV Series is based on displacement, control mode, rotation direction, shaft interface and mounting needs. The final configuration should be confirmed against the application's hydraulic circuit and installation dimensions.

HPV Series Technical Overview

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

HPV Series Displacement and Performance Range

The HPV Series is offered in six rated displacement classes.

The table above gives the performance range by displacement class. Individual operating limits should be evaluated according to the selected configuration and operating conditions.

Rotation Directions

• R — Clockwise
• L — Counterclockwise

Input Shaft

The series documentation lists the following, depending on displacement and configuration:

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.
