Parker PV Series Piston Pump | PV15-2R1E-F02 PV10 PV20 PV29 | High Pressure Axial Pump

The PV Series axial piston pumps from Chengyuan Hydraulic are high-pressure variable displacement components fully compatible with Parker industry standards. Designed for continuous high-pressure open-circuit systems, the PV series is renowned for its exceptional shock resistance and superior self-priming performance. For core models such as PV15-2R1E-F02, PV15-2R1E-C02, and PV62, we utilize reinforced ductile iron housings and precision-ground piston assemblies. Every pump undergoes 100% simulated full-load condition testing to ensure mechanical and volumetric efficiency at 350 bar matches OEM performance, guaranteeing 100% original-place interchangeability.

Key Technical Advantages:

• Superior Shock-Resistant Design: The PV series utilizes extra-thick ductile iron for the pump body. This reinforced structure maintains the geometric precision of the swashplate and piston assembly even under high-frequency backpressure spikes (up to 420 bar), eliminating the risk of housing failure.

• High-Displacement Self-Priming Technology: Optimized suction galleries and valve plate porting ensure excellent self-priming capabilities at speeds of 1500 rpm and above, significantly reducing the likelihood of cavitation during high-flow demands.

• Modular Compensator Controls: Supports a wide array of control modules (e.g., the 2R1E configuration). Whether it’s basic pressure compensation or complex electro-hydraulic power control, the compensator blocks are seamlessly swappable and precision-adjustable.

• Quiet Operational Performance: By minimizing pressure pulsations and optimizing cylinder block balance, the PV series operates at noise levels significantly lower than competing high-pressure pumps, making it ideal for noise-sensitive indoor industrial environments.

Application Areas:

• Heavy-Duty Presses: Primary pumps for metal forging, bending machines, and balers.

• Plastics Industry: Power source for large-scale industrial injection molding systems.

• Marine & Offshore: Ship cranes, winches, and steering gear control systems.

Expert Maintenance Tips:

• Case Drain Management: The PV series is sensitive to case backpressure. Ensure the drain line is short and routed directly to the tank, keeping backpressure below 2 bar to maintain shaft seal integrity.

• Initial Air Bleeding: Before the first startup, the housing must be filled with clean hydraulic oil through the highest drain port. Use short “jog-starts” initially to bleed air from the swashplate and compensator pistons.

• LS Line Inspection: For Load Sensing (C02/LS) models, regularly check the feedback lines for orifice clogging, as this is critical for maintaining rapid compensator response times.
