A10VSO180DG/32L-PPB22U00 A10VSO180DRF/32L-PPB22U00 A10VSO180DRF1/32L-PPB22U00 German Rexroth variable displacement piston pump imported with original packaging

Regular maintenance is essential to extend the pump's service life (typically 10,000-15,000 operating hours with proper care). Follow this schedule:

• Daily Maintenance: Check oil level and top up with compatible hydraulic oil if necessary.
• Inspect for oil leaks at pump connections, seals, and control valves.
• Monitor pump temperature (via touch or temperature sensor) and operating noise (should be smooth, no grinding or knocking).
• Record pressure, temperature, and operating hours in a maintenance log.
• Weekly Maintenance: Clean the breather filter and suction filter (replace if clogged).
• Check the condition of flexible hoses (look for cracks, bulges, or wear).
• Verify that pressure relief valves and control mechanisms are functioning correctly.
• Monthly Maintenance: Take a hydraulic oil sample for analysis (check viscosity, water content, and particle count).
• Calibrate pressure gauges and control signals (for electro-hydraulic models).
• Inspect the drive coupling for wear or misalignment.
• Annual Maintenance: Replace the hydraulic oil and all filters (suction, return, pressure).
• Disassemble the pump (by Rexroth-certified technicians) to inspect pistons, swashplate, and seals for wear.
• Replace worn components (e.g., O-rings, bearing, valve plates) with genuine Rexroth parts.
• Perform a full performance test (flow, pressure, efficiency) to ensure compliance with specifications.

Contamination (from dirt, metal particles, or water) causes 70% of A10VSO pump failures. Follow these steps to address and prevent it:

• Immediate Response to Contamination: Stop the pump immediately to avoid further damage to precision components (pistons, cylinder block).
• Drain the contaminated oil and flush the reservoir with clean hydraulic oil (use a portable flushing unit for thorough cleaning).
• Replace all filters (suction, return, pressure) with new ones of the correct precision.
• Pump Inspection & Cleaning: Disassemble the pump and clean all components with filtered hydraulic oil (avoid harsh solvents).
• Inspect for scratches on the swashplate, piston wear, or damage to the valve plate. Replace any damaged parts.
• Reassemble the pump using new seals and torques fasteners to Rexroth's specifications.
• Preventive Measures: Install a bypass filter (3μm precision) in the hydraulic system to continuously clean the oil.
• Use only clean, filtered oil when topping up the reservoir (use a funnel with a 10μm filter).
• Seal all reservoir openings when not in use and replace the breather filter every 3 months.
• Inspect new oil deliveries for contamination before adding to the system.
