Rexroth High Pressure Variable Displacement ISO9001 Certified Hydraulic Gear Pump Made in Germany

The Rexroth PGH series comprises fixed displacement, gap-compensated internal gear pumps known for their robust construction and efficient performance. Key features include high operating pressures (up to 350 bar), a wide speed range (typically 200 to 3000 rpm), and compatibility with various hydraulic fluids like HLP, HEES, and HFDU.

PGH pumps are widely used in industrial hydraulic systems, including ventilation and pressure compensation systems, mobile machinery, machine tools, and automation equipment.

PGH pumps are compatible with standard hydraulic fluids such as HLP, HEES (synthetic esters), and HFDU (phosphate esters). The optimal operating viscosity range is 10 to 300 mm²/s.

• Fluid Contamination: Dirt, debris, or air bubbles can cause internal wear
• Overheating: Excessive heat can break down lubricants and damage seals
• Mechanical Wear and Tear: Misalignment or excessive pressure
• Cavitation: Occurs when the pump is starved of fluid

• Check reservoir fluid level
• Inspect suction line and inlet filter for blockages
• Ensure fluid viscosity is within recommended range
• Check for air leaks in suction line
