The primary purpose of pulsation control for reciprocating pumps is to attenuate or filter out any pump-generated pulsating pressures which create forces in the piping system that cause vibration and noise. A data chart compares pump pulsation frequencies to pipe span natural frequency of vibration. Another benefit of pulsation control is the reduction of fatigue of the pump liquid end and pump expendable parts. Reducing the pressure peaks seen by the pump piston will reduce the power end peak loading. It is almost mandatory that multiple pump installations have well-designed individual suction and discharge pulsation control equipment. Even though multiple pumps may be arranged to run at slightly different speeds, it is impossible to prevent them from frequently reaching an in-phase condition where all of the pump flow or acceleration disturbances occur simultaneously. The extent of the pipe vibration caused by such disturbances can be multiplied by the number of pumps because the energy similarly is increased. The amplitude of the individual pump pulsations are reduced by the use of dampeners on each pump so that their accumulated effect will be insignificant.
