HPV Series Closed Axial Piston Pumps

Variable Displacement Axial Piston Pumps for Closed-Circuit Systems

The Highland HPV Series represents a family of hydraulic transmission pumps that use closed-circuit axial piston variable displacement technology.

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

Key series technical data covers a 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 parameters. Final configuration should be confirmed with reference to 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 above series table provides the performance range by displacement class. Individual operating limits should be evaluated according to the selected configuration and operating conditions.

Highland Agricultural machinery hydrostatic Transmission introduce

Highland Hydraulic pumps have been around for decades, for one main reason: they don't require an external energy source - the force of fluid provides them with the energy they need. Pump is the variable displacement hydraulic pump that is with charge pump, the control way of variable displacement pump can be manual or hydraulic operated, and can simply control speed, direction and power of the output shaft.

Highland Hydraulic pumps can be connected with other additional pumps.
When Hydraulic pumps operated mechanically, the servo displacement can control and keep the angle of swash plate and pump displacement.
Upon release of the control handle, swash plate return to zero position automatically and the flow reduces to zero.
Hydraulic pumps have shaft oil seals performance, even at the lowest temperature and high case pressure.

Highland Hydraulic oil motor are piston or piston reciprocating direction parallel to the cylinder center axis of the Piston pump. The hydraulic oil motor uses the volume change produced by the reciprocating movement of the plunger in the plunger hole parallel to the drive shaft to work. Because the plunger and plunger hole are round parts, high precision can be achieved, so the volume efficiency is high.

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
