Industrial pump and valve systems are often used continuously in demanding environments. A practical maintenance plan can help reduce unexpected downtime and improve long-term reliability. For pumps, operators should regularly check vibration, noise, temperature, leakage, and pressure changes. Mechanical seals and bearings should be inspected according to operating hours and application conditions. For valves, maintenance should include seal inspection, actuator function testing, opening and closing performance checks, and leakage inspection. Control cabinets and monitoring systems should not be ignored. Loose wiring, alarm records, sensor data, and protection settings should be reviewed regularly.
