Hydrocyclone Feed Pump Pressure PSI vs Operating Parameters

Aug 07, 2015  For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump box that causes this pressure fluctuation.. First the pump pumps all of the
