Internal temperature balancing prevents localized thermal hotspots within the rotating group.
Smooth cross-port transitions reduce hydraulic shock during rapid pressure changes.
Swash control interface supports direct linkage to proportional control systems.
Pressure-balanced block alignment reduces lateral forces and enhances rotational smoothness.
Maintenance-ready access points reduce service time in field applications.

Product Description
HPV pump utilizes a hardened valve plate with optimized port geometry, improving fluid transition and minimizing pressure pulsation. This results in smoother system response and enhanced controllability.
Product Features
Ultra-tight clearance grinding ensures consistent displacement output per revolution.
Multi-stage case drainage reduces aeration and suppresses noise.
Precision-seated valve plates maintain sealing integrity during thermal expansion.
Compact head assembly supports open-loop and closed-loop configurations.
Continuous lubrication of sliding components stabilizes performance over long duty cycles.
PRODUCT INTRODUCTION
Engineered for closed-loop hydraulic systems, Highland HPV70 hydraulic plunger pump provides high efficiency, stable performance, and long-term reliability. It is widely applied in forage harvesters and other agricultural machines to ensure smooth power delivery and optimal hydraulic system control.

Product Application
Packing & Delivery
To ensure the safe delivery of variable piston pump and hydraulic motor, we utilize multiple layers of protective packaging. The pump is first sealed in a durable plastic bag to prevent moisture and contamination. Next, it is securely fixed within a reinforced plywood case to prevent movement and damage during transportation, given the heavy weight of the product. Finally, the plywood case, built to standard export specifications, provides sturdy protection suitable for international shipping.
