Frequently Asked Questions
Q1: What is the PGH series gear pump, and what are its key features?
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.
Q2: What are the common appliions for PGH pumps?
PGH pumps are widely used in industrial hydraulic systems, including ventilation and pressure compensation systems, mobile machinery, machine tools, and automation equipment.
Q3: What hydraulic fluids are compatible with PGH pumps?
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.
Q4: What are the most common causes of gear pump failure?
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
Q5: How can I troubleshoot low or no flow from my PGH pump?
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
