Pump problems

1. Make certain required pumps are running, if not, try restarting.
— check direction of flow through lines, valves and pumps.
2. Check bearings.
3. Check seal water and packing.
— have packing tightened, if needed.
— as temporary measure, flood packing with water.
4. Check for belts that may be slipping.
5. Look for obstructions or restrictions in pumps, valves, and lines; i.e., rags, wood, wire, etc.
6. Check pressure gauges and setup on wear plate at pump.
7. Check flows before and after pump.
— low flow can cause cavitation.
8. Look for sources of entrained air, i.e., agitators or leaks in lines, valves and packing.
