Installation and Maintenance: Common Issues & Solutions

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

• Issue: Low or No Fluid Delivery / Low System Pressure

• Causes: Incorrect pump rotation, broken drive shaft, blocked intake pipe, heavy oil viscosity, air leaks in intake, low fluid level, worn pump parts, relief valve set too low.

• Solutions: Verify pump rotation (check arrow on pump body), inspect/repair drive shaft, drain and replace with clean fluid of proper viscosity, check and tighten intake connections, ensure fluid level is above intake pipe, replace worn internal pump components (e.g., rotor sets, cartridge), adjust relief valve setting.

• Issue: Excessive Noise (e.g., whining, grinding)

• Causes: Clogged or restricted intake strainer/pipe (cavitation), air in hydraulic fluid (aeration), defective bearings, worn components.

• Solutions: Clean or replace clogged strainers/pipes, bleed air from the system, replace defective bearings, inspect and replace worn pump components. Ensure proper oil viscosity and temperature.

• Issue: Fluid Leaks (External or Internal)

• Causes: Worn or damaged seals/O-rings, loose connections/fittings, cracked hoses/lines, excessive pressure on seals.

• Solutions: Replace worn/damaged seals and O-rings, tighten all connections and fittings, inspect and replace cracked hoses/lines. For externally drained pumps, check for restrictions or excessive line length.

• Issue: Overheating Hydraulic Fluid

• Causes: Low fluid level, clogged oil cooler, fluid contamination, excessive system pressure.

• Solutions: Ensure proper fluid level, clean or repair oil cooler, replace contaminated fluid and filters, check and adjust pressure settings (e.g., relief valve).

• General Maintenance Tips:

• Regularly check hydraulic fluid level, color, and quality. Replace fluid and filters according to manufacturer schedules.

• Inspect all hydraulic lines, hoses, and connections for signs of leaks or damage.

• Listen for unusual noises from the pump or system.

• Ensure the pump suction strainer is clean and free of blockages.

• Adhere to manufacturer-recommended warm-up times.
