Hydraulicmarket is an Iranian group of engineers professional in repairing hydraulic pumps. Repairing hydraulic pumps in construction, mining, and agricultural machinery requires precise evaluation of working pressure, flow rate, and leakage levels. Axial piston and gear pumps typically operate between 200 to 350 bar, and even minor wear on pistons or gears can reduce efficiency by up to 15 percent. The repair process includes replacing O-rings, checking axial clearances, testing output flow, and readjusting pressure control valves to ensure the pump can sustain continuous load conditions.
In industrial hydraulic pump repair, calibration tools and dedicated test stands play a crucial role. Flow testing at different motor speeds and pressure endurance checks up to the nominal 300 bar are mandatory. Repair costs vary depending on the pump brand and model, usually ranging between 20 to 40 percent of the price of a new unit. Using genuine spare parts and precision lapping of contact surfaces can extend the equipment’s service life up to 5000 operating hours.
