PV22 + MV23 Hydraulic Pumps Motors For Underground Truck

Optimized Pump and Motor Matching: Highland PV22 hydraulic pump and MV23 hydraulic motor are precisely matched to ensure balanced flow, pressure stability, and efficient power transmission, resulting in smooth vehicle movement and improved driveline performance.
High Torque for Underground Haulage: Designed to deliver strong starting torque and consistent output, this hydraulic solution supports heavy loads and steep gradients commonly encountered in underground mining trucks.
Closed Loop Hydraulic Drive Design: The closed circuit configuration improves energy efficiency, reduces heat generation, and enables fast directional changes, making it ideal for confined underground operating conditions.
Heavy-Duty Construction for Harsh Environments: Manufactured with high-strength materials, precision machining, and reliable sealing systems to withstand dust, vibration, moisture, and continuous high-pressure operation.
Reduced Maintenance and Long Service Life: Advanced wear-resistant components and optimized lubrication reduce downtime, extend service intervals, and lower total cost of ownership for underground truck operators.

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.
