3 Flow rate of slurry can be conveniently measured by magnetic flow meters (which are rather expensive). 4 When positive displacement pump is used for slurry transfer pump speed and displacement can be used to calculate slurry flow rate. 5 Pressure gauges and other instruments mounted on pipe line are susceptible to damage due to vibrations.

PUMPS Why do slurry pumps wear quickly at low flow rates

Although slurry characteristics such as particle size and concentration may first come to mind, an oftenoverlooked factor in long term pump wear is operation at low flow rates relative to the best efficiency point flow rate (BEPQ). But how does low flow rate contribute to pump wear? And what can pump operators do to avoid long term effects?
