our advantage
Product Description
HPV series supports 100% torque thru-drive options, allowing multiple pumps to be mounted in tandem from a single prime mover. This simplifies complex hydraulic architectures, saves space, and reduces installation costs for multi-function machinery.
Product Features
Hardened pistons are engineered for long fatigue life under repetitive high-pressure operation.
Structural housing geometry distributes stress evenly to reduce deformation.
Friction-reducing coatings enhance sliding efficiency in reciprocating elements.
Optimized port plate orifice transitions minimize cavitation at high flow rates.
Controlled case pressure release pathways ensure stable lubrication and cooling.
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.
