Common Installation and Maintenance Issues & Solutions

• Issue: Reduced Flow/Pressure After Installation

  Cause: Air in the system, incorrect rotation of the cartridge, or damaged seals during installation.

  Solution: Ensure proper bleeding of air from the hydraulic system. Verify the cartridge is installed with the correct rotation as indicated by markings. Carefully inspect and replace seals if damaged during assembly.

• Issue: Excessive Noise/Vibration

  Cause: Contaminated hydraulic fluid, cavitation, misalignment, or worn bearings.

  Solution: Regularly check and maintain hydraulic fluid cleanliness. Ensure proper suction line sizing and avoid restrictive fittings to prevent cavitation. Verify pump-motor alignment. If bearings are worn, a complete cartridge replacement is essential.

• Issue: Oil Leakage from Pump

  Cause: Damaged shaft seal, O-rings, or loose mounting bolts.

  Solution: Inspect and replace worn or improperly installed seals. Ensure all mounting bolts are torqued to the manufacturer's specifications. Check for cracks in the pump housing or covers.

• Issue: Overheating Hydraulic Fluid

  Cause: Clogged heat exchanger, excessive internal leakage within the pump, or operating above recommended pressure/flow.

  Solution: Clean or replace the heat exchanger. If internal leakage is significant after cartridge replacement, inspect for proper assembly. Ensure the system operates within the pump's rated parameters.
