HPV Series

Closed Circuit Axial Piston Pump

Variable displacement hydraulic pump for closed loop operation

Our Highland HPV series closed circuit axial piston pumps are built to meet your toughest demands. As the next generation, developed from the trusted PV Series, the HPV Series offers upgraded performance across key areas to deliver the power, reliability, and efficiency your operations need.

Key Parameters

Displacement (ml/r): 30, 50, 70, 90, 110, 130

Rated pressure (Mpa): 35

Max. pressure (Mpa): 42

Features

Here’s what makes the HPV Series stand out:

Optimized Refill System: Unlike the traditional PV Series, which uses an external gear pump for refilling, the HPV Series features a cycloidal internal gear pump. This design ensures each pump’s refill system operates independently in multi-pump setups, boosting stability and reliability across your entire system.
Enhanced Design:

We’ve replaced the ball-joint helical spring with a disc spring, making the pump’s overall diameter smaller. This means you get more compact pumps with the same displacement, saving valuable installation space.

Our upgraded high-pressure oil seals make maintenance easier, reduce the risk of hydraulic leaks, and enhance cleanliness and durability for a longer-lasting system.
Cost-Effective Solution: Through refined design and efficient manufacturing, we’ve kept production costs down, allowing us to offer you a high-performance pump that’s also budget-friendly.

Typical Applications

With models like the HPV30, HPV50, HPV70, HPV90, HPV110, and HPV130, the HPV Series covers a range of flow requirements for various applications. Whether you’re in agriculture, construction, road-building, mining, or industrial sectors, these pumps are engineered to provide the dependable hydraulic power you need.
