Eaton Vickers PVM Piston Pump | PVM018 PVM022 PVM046 PVM065 | PVM-022-B1UB-RSAY-P-1NNNN

LIC Hydraulic proudly offers the Vickers PVM Series, the premier solution for quiet-running hydraulic power. The PVM series is an axial piston variable displacement pump specifically engineered for applications where noise reduction and high power density are critical. Models like the PVM-022-B1UB-RSAY-P-1NNNN utilize Eaton’s patented valve plate timing technology, effectively dampening hydraulic shock and noise. Built with a high-strength ductile iron housing, the PVM series minimizes vibrations while providing a rated continuous pressure of 280 bar. Our PVM units offer 100% original interchangeability, ensuring a direct-fit replacement with guaranteed volumetric and mechanical performance.

• Robust Ductile Iron Housing: Superior material choice compared to aluminum housings, offering better fatigue resistance and better acoustic insulation.

• Compact High-Efficiency Core: The internal piston and swashplate assembly provide maximum displacement in a minimal footprint, allowing for easy integration into modern engine compartments.

• High Dynamic Response: The P-type compensator ensures fast and accurate stroke adjustment, preventing pressure spikes and enhancing overall system energy efficiency.

Application Areas

• Industrial Plants: Machine tools, automotive assembly lines, and power units for manufacturing presses.

• Specialty Vehicles: Sweepers, refuse trucks, and utility vehicles requiring quiet operation.

• Agriculture: High-efficiency auxiliary hydraulics for tractors and harvesters.

Expert Maintenance Tips

• Case Priming: Before the first start, fill the pump case with clean hydraulic oil through the uppermost drain port. Air trapped inside will cause internal components to fail within seconds.

• Case Drain Management: Ensure the drain line is plumbed directly to the reservoir with zero restriction. Excessive case backpressure (above 1.5 bar) will damage the shaft seal and negatively impact noise performance.

• Cleanliness Monitoring: Maintain an ISO 4406 18/16/13 cleanliness level. Regularly check suction screens and return filters to protect the precision-machined piston bores and valve plates.
