Blacoh Fluid Control, Inc.
Surge and Pulsation in Pumping Systems Both surge and pulsation in a fluid processing system are the result of uncontrolled pressure waves caused by an abrupt change in fluid velocity. Fluid contained in an enclosed piping system has a physical volume and, therefore, its mass can be calculated. We can then determine acceleration forces needed to move that mass. Once in motion, the mass will stay in motion as long as enough force is applied to overcome friction loss plus any gravitational component. It can be said that hydraulic...
