The Rexroth PGH series internal gear pump is a fixed displacement pump primarily composed of pump body, bearing cover, internal gear ring, small gear shaft, sliding bearing, axial plate, end cover, installation flange and stop pin, with oil distribution components including oil distribution plate, oil distribution frame and sealing roller.
Key Features
High-end advanced efficiency with low displacement, low working noise, and low flow pulsation
Available in model specifiions 2, 3, 4, 5
2X series upgraded to 3X with unchanged installation and connection dimensions
Sealing gap compensation enables efficient operation at low speeds and viscosities
Suitable for various speeds and viscosity ranges
Compatible connection with vane pumps and axial piston pumps
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. Fluid temperature should generally be maintained between -10°C to +80°C for HLP fluids and -10°C to +50°C for special fluids.
What are the most common causes of gear pump failure?
Fluid Contamination: Dirt, debris, or air bubbles can cause internal wear, clogging, and failure.
Overheating: Excessive heat can break down lubricants, damage seals, and cause bearing failure.
Mechanical Wear and Tear: Misalignment, excessive pressure, or running outside specified parameters.
Cavitation: Occurs when the pump is starved of fluid, leading to noise and damage.
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
Verify pump rotation direction
Inspect internal components for wear
How can I resolve issues with low system pressure or pressure fluctuations?
Check for internal leakage in worn components
Verify relief valve setting and functionality
Check for fluid contamination and change if needed
