PGI102-2-004-RK03-11-6100 HYDAC Internal Gear Pump High Pressure

Product Overview

The PGI102-2-004-RK03-11-6100 is a high-pressure internal gear pump from the HYDAC PGI series (PGI101/PGI102/PGI103 heavy-duty range). With a geometric displacement of 3.8 cm³/rev, clockwise rotation, SAE A 2-hole mounting flange, ISO keyed shaft Ø20 mm and Viton seals, it is designed for open-loop hydraulic systems. The pump features low noise, low pulsation, a wide speed range and high volumetric efficiency. It offers direct bolt-on interchangeability with OEM units and undergoes 100% simulated duty testing for reliable high-pressure performance in industrial and mobile applications.

Key Technical Advantages

1. True drop-in interchangeability: Manufactured to OEM dimensional, flange and shaft standards for bolt-on replacement without modifications.
2. Low noise and low pulsation: Optimized internal gear design delivers smooth operation with significantly lower noise than conventional external gear pumps.
3. High volumetric efficiency and wide speed range: Precision-machined gears and housing support speeds up to 4200 rpm, ideal for variable-speed or wide-range applications.
4. Heavy-duty high-pressure construction: Cast-iron housing rated to 330 bar continuous / 400 bar peak, with optimized bearings and seals for long service life.
5. 100% simulated duty testing: Full pressure, flow, noise and endurance verification before shipment ensures ready-to-install reliability.

Application Areas

• Industrial hydraulic power units and machine tools
• Injection molding machines, presses and metallurgical equipment
• Auxiliary hydraulic systems on mobile machinery
• Open-loop systems requiring low-noise, high-pressure compact internal gear pumps
• Multiple-pump assemblies

Expert Maintenance Tips

• Confirm clockwise rotation and flange/shaft compatibility before installation; use recommended HLP hydraulic oil and maintain cleanliness to ISO 20/18/15.
• Start at low speed unloaded; check for leaks and noise. Avoid simultaneous maximum pressure and maximum speed.
• Regularly inspect seals and bearings; ensure unrestricted suction lines to prevent cavitation.
• Keep oil temperature within –40 to +120 °C and viscosity in the 10–300 cSt recommended range.
• For multiple-pump or special configurations, verify the full order code and consult technical support regarding interfaces and torque limits.
