This article discusses the operation and operational assessment/management of pumps and how to deal with the operational problems of 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. Impeller pumps work best when it's run on a regular basis. What is the useful life of an impellar? One method to reduce the noise your water feature makes is to add more plants and rocks to the area.

TY. impeller - I don't know why the impeller is able to spin both ways when you are holding the shaft and keeping it from rotating. Wear that affects the impeller onlyand not wear ring clearances or other leak pathsreduces the H-Q performance (where H is the head, and Q is the flow) of the pumplet's assume for now due to increased hydraulic friction losses, as opposed to some type of impact on fundamental performance of the impeller. Step 3. Sometimes debris will get into the pump and will crack the impeller. Replace lid. When the pressure gauge is above the manufacturers recommended pressure, the filter needs to be cleared. Apply a thin coat of lithium- or high-temperature grease to the bearing surfaces and the shaft before reassembling them.

As an example, changing from mild steel (reliability factor of 1.0) to stainless steel (reliability factor of 4.0) would increase the impeller life from cavitation damage by a factor of four. This will cause the motor to hum or vibrate. Thus, with a plugged pump, bhp may increase or decrease depending on the relative impact of impeller plugging versus an increase in mechanical losses.
