FAQ:

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. Fluid temperature should generally be maintained between -10°C to +80°C for HLP fluids and -10°C to +50°C for special fluids.

Q4: What are the most common causes of gear pump failure?

Common failure causes include:

• 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. This can result from high fluid temperatures, insufficient lubrication, or overloading.

• Mechanical Wear and Tear: Misalignment, excessive pressure, or running outside specified parameters can accelerate wear on gears, bearings, and seals.

• Cavitation: This occurs when the pump is starved of fluid, often due to a clogged inlet filter, restricted suction line, or low fluid level, leading to noise and damage.

Q5: How can I troubleshoot low or no flow from my PGH pump?

• Check that the reservoir fluid level is adequate.

• Inspect the suction line and inlet filter for blockages or clogs and clean them if necessary.

• Ensure the fluid viscosity is within the recommended range for the operating temperature.

• Check for air leaks in the suction line and ensure all connections are tight.

• Verify that the pump's rotation direction is correct.

• Inspect internal components (gears, shaft seal) for excessive wear.

Q6: How can I resolve issues with low system pressure or pressure fluctuations?

• Internal Leakage: Check for worn gears, pump housing, or side plates, which can cause internal leaks and pressure loss. Replacing worn parts is often necessary.

• System Relief Valve: A malfunctioning or incorrectly set relief valve can cause low pressure. Verify its setting and functionality.

• Fluid Contamination: Contaminated fluid can damage precision surfaces and cause erratic pressure. Check filters and change the fluid if needed.
