A4SO and A10VSO rexroth pump repair , Iran

The Rexroth A4SO and A10VSO hydraulic pumps used in industrial press machines are axial piston pumps with variable displacement. They operate at pressures of 250 to 320 bar and flow rates from 20 to 350 liters per minute. The housing is made of hardened steel, and internal components are precision-machined to reduce wear and leakage. Seal rings and O-rings ensure stable performance at temperatures between 30°C and 90°C. The design allows for rapid replacement of internal components, minimizing downtime and ensuring consistent machine operation.

The main causes of failure include wear of pistons and cylinders, damaged O-rings, contamination of hydraulic oil, and operation under excessive pressure. Internal leakage reduces efficiency and output flow. Using hydraulic oil with incorrect viscosity or contaminated oil shortens pump lifespan. Malfunctioning control valves and pressure relief valves can also disrupt industrial press operation, necessitating specialized repair.

The repair process involves disassembling the pump, inspecting, and replacing pistons, cylinders, and O-rings. After component replacement, pressure and flow tests are conducted to ensure optimal performance. In severe cases, the housing may be rebuilt or shafts and bearings replaced. All replacement parts must meet Rexroth standards with precise machining to maintain pump longevity and ensure the industrial press system operates efficiently.You can order and buy A4SO and A10VSO rexroth pump repair from Iran by contacting us through whatsaap and email.
