The Rexroth A10VSO series hydraulic pump is a German-engineered high-pressure plunger pump designed for demanding industrial and mining applications. This model features variable displacement and pressure compensation for optimal performance.

• High-pressure operation for industrial and mobile hydraulics
• Variable displacement with pressure compensation
• ISO-certified construction for reliable performance
• Available with threaded or flanged inlet connections
• Radial shaft seal design for enhanced durability
• Nominal displacement: 28 cm³/rev (1.71 in³/rev)

• Possible Causes: Clogged oil filter, low oil level, air leakage, internal pump leakage, incorrect motor rotation
• Solutions: Clean/replace filter, check oil level, inspect seals, replace worn components, verify motor rotation

• Possible Causes: Control mechanism deviation or wear
• Solutions: Reset controller, tighten/replace damaged parts

• Mechanical Causes: Misalignment, damaged coupling, bearing wear
• Hydraulic Causes: Restricted inlet, clogged filter, high viscosity oil
• Solutions: Realign components, replace bearings, check oil specifications

• Possible Causes: Improper clearances, high-pressure leakage, clogged filter
• Solutions: Adjust clearances, increase cooling capacity, clean/replace filter

• Common Leak Points: Shaft seal, internal leakage points, pipe connections
• Solutions: Replace seals, inspect/replace defective components, tighten connections

• Maintain oil temperature between 25-60°C
• Ensure oil cleanliness level ≥ 8 (ISO 4406)
• Conduct comprehensive inspections every 6 months
• Check oil replenishment pump status after 3000 hours of operation
• Always prime pump before starting to prevent dry friction

• Pump/motor shaft concentricity < 0.05mm
• Maximum suction height: 500mm
• Use original Rexroth spare parts for replacements

• Mineral-based hydraulic oils (ISO VG 15-68)
• Synthetic or biodegradable fluids (verify compatibility)
• Maintain cleanliness to ISO 4406 18/16/13 or better

• Construction machinery (excavators, loaders)
• Industrial presses and injection molding equipment
• Material handling systems
• Agricultural machinery

The pressure compensator can be adjusted via the control screw. Always refer to the manual for proper calibration procedures and perform adjustments under controlled conditions.
