HPV Series Closed Axial Piston Pumps

Variable Displacement Hydraulic Pumps for Closed-Circuit Systems

The Highland HPV Series consists of a range of variable displacement axial piston pumps for closed-circuit hydraulic transmission systems.

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

The technical data for the series includes rated speed 2500 r/min, minimum continuous operating speed 500 r/min, rated working pressure 35 MPa, continuous working pressure 30 MPa, and maximum instantaneous working pressure 42 MPa.

The HPV Series can be specified according to displacement, control mode, rotation direction, shaft interface as well as mounting requirements. Final configuration should be verified against the application hydraulic circuit and installation dimensions.

HPV Series Technical Overview

Also included in the supplied technical drawing is 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.
