Precision-lapped slipper surfaces ensure balanced loading across all pistons, improving rotary group stability.
Hardened valve plate coatings resist micro-fatigue and scoring under continuous high-pressure cycling.
Enlarged suction port geometry reduces inlet flow resistance and enhances low-speed self-priming capability.
Advanced shaft sealing systems maintain integrity under elevated temperature and contamination exposure.
Compact, modular body design simplifies integration in space-restricted equipment layouts.
HPV90 Hydraulic Plunger Pumps For Forage Harvesters
Highland HPV90 hydraulic plunger pumps provide efficient, high-pressure hydraulic power
for forage harvesters, ensuring reliable operation and enhanced productivity in agricultural systems.
our advantage
Product Description
HPV series features a robust, segmented design with accessible wear components. This simplifies inspection, servicing, and seal replacement, reducing mean time to repair (MTTR) and lowering the total cost of ownership (TCO) in industrial settings.
Product Features
Multiple control options, including hydraulic servo, mechanical lever, and electro-proportional actuation, support diverse system requirements.
Tight piston-to-bore tolerances reduce internal bypass flow, maximizing volumetric efficiency.
Dynamic balancing of the rotating group minimizes vibration and reduces bearing fatigue.
Compatible with high-temperature and high-viscosity hydraulic fluids for harsh working environments.
Reinforced housing rib structure improves rigidity and reduces resonance during high-load 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.
