HPV Series Closed Axial Piston Pumps

Variable Displacement Axial Piston Pumps for Closed-Circuit Systems

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

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

The technical data for the series includes 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.

The HPV Series can be specified according to 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

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.

HPV Series Displacement and Performance Range

Altogether, the HPV Series covers 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.

Highland Mobile machinery hydrostatic transmission product information:

Highland Mobile machinery hydrostatic transmission is a typical volumetric fluid machine, driven by the prime mover, converting the input mechanical energy into the pressure energy of the liquid, and then inputting it into the system in the form of pressure and flow. Mobile machinery hydrostatic transmission is the power source of the hydraulic system.

Notices:

Hydraulic oil

The suitable replacement period for hydraulic oil in a sealed tank system is 2000 hours, and more often if the hydraulic oil is contaminated with water or other external materials or subjected to abnormal operating conditions.

As a general recommendation, the 10µ inlet oil filter should be replaced every spring or every 1500 hours (whichever occurs first) on a sealed tank system, or in an open tank system with an air filter fill cap. The oil filter should be replaced every 500 hours.

Heat Exchanger

The heat exchanger core and fins are kept clean at all times for maximum cooling and system efficiency, and the exterior of the heat exchanger is checked daily for blockages and cleaned as needed.

Applications:

Mixer truck: concrete mixer truck, cement mixer truck;

Coal mining machinery: scraper;

Industry: pharmaceutical machinery;

Transport vehicles: road rollers, concrete pump trucks, stabilized soil mixers

Application Scope

The HPV Series is documented as belonging to the closed-circuit axial piston pump category.

The supplied project documentation includes an agricultural machinery reference for the HPV130-MA-R-23 configuration, specifically a potato harvester in Kyrgyzstan.

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

HPV Series Model Selection

The HPV model number is structured as:

HPV + Displacement + Control Mode + Rotation Direction + Shaft Configuration + Auxiliary Mounting Configuration

Example Model Code

HPV130-MA-R-23

• HPV — HPV Series closed axial piston pump
• 130 — 130 mL/rev rated displacement class
• MA — Manual servo control
• R — Clockwise rotation
• 23 — 23-tooth input shaft configuration

The complete model should be verified against the applicable model-selection table and engineering drawing before ordering.
