How to Extend the Service Life of Centrifugal Chemical Process Pumps?

Pre-start check: Verify rotor flexibility, lubricant quality, valve operation, bolt tightness, intake cleanliness, motor direction, and control system accuracy.

Priming & startup: Prime the pump (via filling or vacuum pump); start with discharge valve closed, open gauge valves after stable speed, then gradually open the valve (avoid closed-valve operation exceeding 2-3min).

Operation management: Monitor noise, vibration, bearing temperature (≤75℃), and instrument stability; regular oil changes, packing adjustment, and bolt inspection; keep cooling systems unobstructed and check suction water level.

Shutdown: Close gauge valves first, then the discharge valve; drain pump body to prevent freezing; ensure water hammer protection systems work effectively.
