Parker PV040 Series Axial Piston Pump | PV040R1K1T1WMMC Variable Displacement | PV080 PV092 PV140 PV180 PV270

Chengyuan Hydraulic offers the PV series axial piston variable displacement pumps, meticulously engineered as high-performance replacements for Parker industrial standards. This range includes the PV040R1K1T1WMMC and extended models such as PV080, PV092, PV140, PV180, and PV270. The PV series is renowned for its robust “Piston-style” construction and exceptional pressure capabilities. Chengyuan guarantees 100% Drop-in Interchangeability regarding mounting flanges, shaft ends, and compensator control logic. Backed by our 100% Simulation Load Testing, each pump is validated for superior volumetric efficiency at continuous pressures of 350 bar, providing a reliable alternative to original imports while minimizing maintenance costs.

Technical Specifications 

• Model: PV040R1K1T1WMMC (and the full PV range)

• Maximum Speed: 2800 r/min

• Rotation: R (Right/Clockwise)

• Control Type: MMC (Pressure compensator control)

• Seal Material: FKM (Fluorocarbon seals for high temperature and media resistance)

Key Technical Advantages:

• High-Pressure Duty Design: The housing is cast from high-strength ductile iron with reinforced cylinder walls, allowing it to withstand transient peaks of up to 420 bar, ideal for heavy-duty industrial environments.

• Large Piston Load Bearing Area: An optimized swashplate piston design reduces unit surface stress. Combined with Chengyuan’s precision lapping process, it significantly minimizes wear between the piston and slipper.

• Integrated Vibration Damping: Unique valve plate timing and pre-compression chamber technology offset pressure pulsations. This results in exceptionally low noise levels during operation, improving the factory workspace.

• High-Efficiency Bearing Assembly: Utilizing premium high-load thrust bearings, the rotor group maintains precise alignment even under off-center loads or high speeds, reducing internal leakage and extending service intervals.

Application Areas:

• Heavy-Duty Presses: Main power systems for forging, stamping, and scrap baling machines.

• Industrial HPUs: Rolling mill control systems in steel plants and paper machinery.

• Construction Equipment: Luffing systems for heavy cranes and TBM excavation circuits.

• Marine Engineering: Deck winches and steering gear control systems.

Expert Maintenance Tips:

• Case Drain Installation: Ensure the drain line is routed from the highest port on the pump body. The line diameter must not be smaller than the port size to keep the case full of oil and prevent bearing dry-run failure.

• Fluid Cleanliness: As high-pressure precision components, PV pumps require filtration to ISO 4406 18/16/13 or better. Dedicated return filtration is highly recommended.

• Pressure Adjustment Protocol: When commissioning or adjusting the compensator (MMC), always increase pressure slowly from a low setting. Never force the adjustment screw against a locked load.
