Pump Parts & Servicing
Keeping pumps in good repair costs far less than unplanned downtime. Pump parts and servicing covers the seals, bearings, impellers and wear parts that wear out with normal use, along with the expertise to rebuild pumps to like-new condition.
Common Pump Parts
- Mechanical seals and packing – stop leaks at the shaft
- Bearings and bearing frames – restore smooth, quiet operation
- Impellers, casings and wear rings – recover lost flow and efficiency
- Diaphragms, valves and balls – rebuild kits for AODD and metering pumps
- Couplings and baseplates – keep pump and motor aligned
When to Service a Pump
Warning signs include leaking seals, rising vibration or noise, higher motor amps, falling discharge pressure and overheating bearings. Keeping the pump's model and serial number on record makes ordering parts much faster. Planned rebuilds during shutdowns keep surprises to a minimum.
Centro supplies pump parts and repair services for many pump brands, from small metering pumps to large process pumps.
