In general a pulsation dampener is used when one or more of the following criteria are required: to prevent potential pipe vibration, to reduce the load on the pump to minimize or eliminate pulsation for spraying application or other downstream requirement. It works by means of an air cushion created by the pressure of the media pushing the diaphragm upward. This allows air to enter the chamber keeping the diaphragm center at midstroke. During operations the diaphragm flexes thus absorbing and equalizing the pressure surge. Properly sized and installed these dampeners provide evirtually surge-free discharge flow. Dampeners are available in connection sizes ranging from 3/8 inch to 3 inch and come in a range of materials and connections for compatibility with all of our pumps.
