Closed loop hydraulic pump/hydraulic motor manufacturer & hydraulic solutions provider - Highland Hydraulic

Asphalt Pavers Variable Displacement Plunger Pumps

Asphalt Pavers Variable Displacement Plunger Pumps

Precise Variable Displacement Control: Designed to accurately adjust flow and pressure according to paving speed and load conditions, ensuring smooth asphalt laying, stable screed operation, and consistent surface quality.
High Pressure Performance: Built to operate reliably under continuous high-pressure conditions, Highland plunger pumps provide strong and stable hydraulic power required for asphalt pavers.
Excellent Load Adaptability: Highland plunger pump automatically responds to load fluctuations during paving, minimizing pressure shocks and maintaining consistent hydraulic output.
Durable Construction for Harsh Conditions: Manufactured with reinforced housings, high-strength materials, and precision-machined components to withstand vibration, dust, and heat.
Efficient and Low Maintenance Design: Optimized internal flow paths reduce energy loss and heat generation, while high-quality components extend service life and reduce maintenance frequency, lowering total operating costs.

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.
