A suction stabilizer to keep the contact of the fluid with the plunger is one of the best ways to prevent pulsation. Some pumps are naturally noisy, and the only way to resolve this issue is to invest in a new quiet pump. The sound of a pool pump vibration caused by cavitation can be identified by a seeming rumbling rock sound or distinctive popping. To ensure that the pump is getting adequate flow, check the valve often, and ensure that it is open.
