HPV Series Closed Axial Piston Pumps

Variable Displacement Axial Piston Pumps for Closed-Circuit Systems

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

The line-up covers rated displacements of 30 to 130 mL/rev, and offers multiple control modes, rotation directions, input shaft configurations and auxiliary mounting flange options.

Typical series technical data comprises 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 is configurable by 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

The technical drawing provided also contains a configuration-level technical requirement for a 30 MPa rated working pressure. 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 comes in six rated displacement classes.

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

Control and Configuration Options

The HPV Series is organised around a model-selection structure covering displacement, control mode, rotation direction, input shaft and auxiliary mounting flange.

Available Control Modes

• MA — Manual Servo Control
• EP — Electric Proportional Servo Control
• HS — Hydraulic Servo Control

Direction of Rotation

• R — Clockwise
• L — Counterclockwise

Input Shaft Configurations

Depending on the displacement and configuration, the documentation lists:

• 21-tooth shaft, 16/32 pitch
• 23-tooth shaft, 16/32 pitch
• 14-tooth shaft, 12/24 pitch
• Z-axis tapered shaft, 1-20 UNEF

Auxiliary Flange

Configurations available include:

• SAE A
• SAE B with 13-tooth spline sleeve
• SAE B with 15-tooth spline sleeve
• No auxiliary mounting flange

The model-selection table should be used alongside the engineering drawing when the final pump configuration is selected.

Hydraulic Interface and Rotation Direction

The engineering drawing sets out the hydraulic connections and corresponding port arrangements for clockwise and counterclockwise rotation.

The documented configuration is as follows:

• R — Clockwise rotation
