PAVC65BR13 Parker PAVC65 Hydraulic Piston Pump 65cc 3000PSI

Product Overview

The PAVC65BR13 is a high-precision, fully interchangeable replacement for the Parker Hannifin PAVC65 medium-pressure supercharged variable axial piston pump. Designed for open-circuit applications, it features a built-in supercharger for reliable high-speed operation up to 3000 RPM. Constructed with a high-strength cast-iron housing, replaceable bronze-clad port plate, and hydrodynamic cylinder barrel bearing, this pump delivers consistent flow and efficiency in both mobile and industrial hydraulic systems. Every unit undergoes 100% simulated operating condition testing to ensure exact dimensional, interface, control, and performance interchangeability with original Parker PAVC65 pumps—enabling drop-in replacement without modification.

Key Technical Advantages

1. Built-in Supercharger: Significantly enhances inlet performance, enabling stable high-speed operation up to 3000 RPM while minimizing cavitation risk—ideal for high-speed mobile equipment.
2. High-Strength Cast-Iron Housing with Two-Piece Design: Delivers superior rigidity and impact resistance while allowing easy field disassembly and service, reducing downtime.
3. Replaceable Bronze-Clad Port Plate and Hydrodynamic Cylinder Barrel Bearing: Provide excellent volumetric efficiency and extended service life with reduced wear, maintaining low leakage even under severe duty cycles.
4. Cartridge-Type Controls: Field-changeable control modules (pressure compensation, load sensing, power limiting, etc.) allow quick adjustment or replacement of control functions without removing the entire pump, maximizing system flexibility and serviceability.
5. Standard Air Bleed and Sealed Shaft Bearing: Enables rapid priming; shaft seal is exposed only to inlet pressure, further improving reliability and seal life.

Application Areas

• Construction and mobile equipment (excavators, loaders, crane auxiliary systems)
• Industrial hydraulic systems (injection molding machines, presses, machine tools)
• Specialty vehicles and material handling equipment
• Food processing and specialty fluid applications
• Open-circuit hydraulic power units requiring medium pressure, high speed, and reliable variable control

Expert Maintenance Tips

• Ensure adequate inlet line sizing and minimize restrictions; dual inlet configuration is recommended for speeds above 2700 RPM to prevent cavitation.
• Fully bleed the system before initial start-up using the standard air-bleed feature.
• Control drain pressure must not exceed 7 bar; install a filter and/or cooler in the drain line as needed.
• Periodically inspect the port plate and cylinder barrel interface for wear; use the correct seal kit (e.g., SKPAVC6513) when replacing seals.
• Maintain fluid cleanliness at ISO 16/13 or better; recommended viscosity 30–50 cSt. Avoid prolonged simultaneous operation at peak pressure and maximum speed to maximize bearing life.
