Installation & Maintenance: Common Issues & Solutions

Proper installation and regular maintenance are crucial for the longevity and efficient operation of hydraulic vane pumps. Here are common issues and their solutions:

• 1. Cavitation & Aeration:

  Issue: Gaseous bubbles forming and collapsing in the fluid, causing noise, vibration, and damage to pump parts. Often due to restricted inlet, low oil level, or incorrect fluid viscosity.                
  Solution: Ensure proper inlet line sizing, maintain correct fluid levels, use recommended fluid viscosity, and check for air leaks in the suction line. Replace damaged parts promptly.

• 2. Excessive Wear & Contamination:

  Issue: Abrasive particles in the hydraulic fluid causing accelerated wear of vanes, rings, and rotors, leading to reduced efficiency and potential failure.                
  Solution: Implement a robust filtration system, regularly check and replace filters, perform oil analysis to monitor contamination levels, and ensure proper fluid cleanliness standards are met. Use our high-quality replacement parts for durability.

• 3. Overheating:

  Issue: Elevated fluid temperatures can degrade hydraulic fluid, seals, and pump components, reducing efficiency and lifespan. Causes include excessive system pressure, undersized cooler, or internal leakage.                
  Solution: Verify system pressure settings, ensure cooling system is adequate and functioning correctly, check for internal bypasses or leakage within the pump or system components. Regular fluid changes with appropriate cooling are vital.

• 4. Seal Leaks & Loss of Pressure:

  Issue: Worn or damaged seals leading to external leaks or internal bypass, resulting in pressure drop and inefficient operation.                
  Solution: Periodically inspect seals for signs of wear or damage and replace them as part of routine maintenance. Ensure proper installation techniques to prevent pinching or tearing of seals. Address any internal wear that might lead to increased clearances and leakage.
