Compatibility: Reinforced Impeller Blades compatible with Summer Waves SFX1500+, SFX1000 pool pumps. To explain further, if the impeller is completely plugged, or worn to nothing, there would be zero flow and zero pressure generation, yet there would be still some power read on the electric meter because the pump still consumes power on rubs of the bearings, seals and other mechanical losses. So, in that example, the power would be small, but still not zero. didn't try to force it. No, a pool pump should not be loud. A 100-horsepower (hp) pump may have 3 to 5 hp in such mechanical losses.

Pumps with closed-style impellers will include a casing wear ring and possibly an impeller wear ring that is fitted to the outside diameter (OD) of the impeller suction eye, both of which are suction side wear rings. Pumps where the impellers are plugged and the data just before failure shows lower than expected bhp? If necessary, replace with new bearings. The noise should be noticeable but not overly loud. For maximum safety turn off the power at the circuit breaker to the motor - usually located next to the timer box. In addition, pool pumps receiving heavy use in frequently used spas and swimming pools may have a shorter lifespan due to the increased wear and tear that comes with more frequent use.
