Hydraulic pump maintenance involves inspecting and replacing internal components such as rotors, vanes, rollers, valves, and bearings to maintain system efficiency above 90% and working pressure up to 250 bar. Pump displacement ranges from 10 to 500 cc per revolution, with oil flow from 20 to 300 liters per minute. Shaft and bearing alignment must be controlled within 0.05 millimeters, and seals, including NBR or FKM, are replaced to prevent oil leakage.
Post-repair performance tests include checking pressure and flow under static and dynamic conditions. Operating temperature should remain between 0 and 90°C, and noise below 75 dB. Non-destructive testing NDT, including radiography and ultrasonic inspection, is performed on the shaft and housing. Repairs following ISO 4406 and DIN 51524 standards can extend pump service life beyond 10,000 hours.

Industrial water tanks are typically constructed from carbon steel with internal and external anti-corrosion coating, ensuring structural durability against internal pressure up to 10 bar and temperatures up to 90°C. Typical storage capacity ranges from 5 to 500 cubic meters, with wall thickness varying between 6 to 20 millimeters depending on tank diameter. The foundation and support structure are designed according to API 650 and ASME BPVC standards to withstand seismic forces and hydrostatic pressure.
Tank welding is performed using MIG/TIG technology, with non-destructive testing NDT including radiography and ultrasonic inspection. Inlet and outlet connections are designed according to system requirements, featuring class 150 and 300 flanges, safety valves, and pressure gauges. External painting uses 150-micron epoxy powder coating to ensure high resistance against UV radiation and harsh industrial environments.
