HPV Series Closed Axial Piston Pumps

Variable Displacement Hydraulic Pumps for Closed-Circuit Systems

The Highland HPV Series represents a family of closed-circuit axial piston variable displacement pumps designed for hydraulic transmission systems.

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

Key series technical data covers 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 set up according to displacement, control mode, rotation direction, shaft interface and mounting requirements. Final configuration should be confirmed against the application hydraulic circuit and installation dimensions.

HPV Series Technical Overview

The supplied technical drawing also includes a configuration-level technical requirement indicating 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

Six rated displacement classes are offered across the HPV Series.

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

Auxiliary Mounting Flange

Available configurations 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 together with the engineering drawing when selecting the final pump configuration.

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.
