PAVC65BL42AP13 Parker Medium Pressure Piston Pump 65cc 207bar

Product Overview

The PAVC33 / PAVC38 / PAVC65 / PAVC100 series (example: PAVC65BL42AP13) is a Parker Hannifin medium-pressure super-charged variable-displacement axial piston pump designed for open-circuit applications. The built-in supercharger ensures high-speed capability while flow is infinitely variable with swashplate angle. The unit offers 100% drop-in interchangeability with genuine Parker pumps—no piping or mounting modifications required. Every unit undergoes full simulated operating-condition testing to guarantee high volumetric efficiency and reliability under medium-to-high pressure and speed.

Key Technical Advantages

1. Built-in supercharger design significantly improves suction capability, supporting high-speed operation up to 3000 rpm and reducing cavitation risk.
2. Precision swashplate and replaceable bronze-clad port plate combined with hydrodynamic bearings deliver high volumetric efficiency and low internal leakage for extended high-pressure life.
3. Field-changeable cartridge-style controls enable rapid response and easy maintenance across pressure compensation, load-sensing and power-limiting modes.
4. High-strength two-piece cast-iron housing and sealed shaft bearing subject the case only to inlet pressure, improving reliability and allowing filtered/cooled drain lines (max. 7 bar).
5. 100% interchangeability plus full operating-condition testing ensures exact match of mounting dimensions, ports and control characteristics with original Parker PAVC units, minimising downtime.

Application Areas

Designed for medium-pressure open-circuit systems including industrial power units, injection moulding machines, presses, machine tools, mobile auxiliary circuits, agricultural machinery, material-handling equipment and other applications requiring variable flow with pressure compensation.

Expert Maintenance Tips

1. Before installation, verify rotation direction, shaft spline and flange match; ensure precise alignment and avoid radial or axial overloads. Dual-inlet configuration is recommended for high-speed duty.
2. Fully bleed the system via the standard air-bleed port before first start-up. Use hydraulic fluid meeting ISO 16/13 cleanliness or better; viscosity and temperature must suit the –40 °C to 71 °C operating range.
3. Periodically check drain-line pressure (max. 7 bar) and case temperature; maintain inlet pressure within limits to prevent cavitation.
4. When changing filters and oil, inspect the port plate and pistons for wear. Cartridge controls are field-replaceable; perform preventive maintenance at the end of design life or when flow decreases to maximise system longevity.
