Pulsation dampeners, also called accumulators and surge suppressors, control and minimize the pulsating effects stroke engines create on pressurized systems. The added control created by pulsation dampeners extends the life of pipes, pumps, meters and valves while making them run smoother and more efficiently. Pulsation dampeners lower the cost of operating pressurized systems making them an important and cost saving purchase.

Pulsation dampeners come in a variety of styles with specific applications for gas and liquids as well as the various viscosities. Inlet type, inlet size, maximum, pressure and capacity are the primary specifications to address with a pulsation dampener. Additional considerations are the materials and mechanisms used to provide the best solution for a given application. When purchasing pulsation dampeners consider the following:

1. Look to adjustable pulsation dampening distributors for applications that use variable pressures.

2. Buy automatic pulsation dampeners for constant flow applications to make monitoring more efficient.

3. Find chargeable pulsation dampener providers for high flow or temperature pumping operations.

Action Steps
The best contacts and resources to help you get it done

Smooth out your pumping system with an adjustable pulsation dampener

Adjustable pulsation dampeners allow the flow of air or liquid to adapt to variations in pressure. Operations where the desired flow changes for specific applications benefit from the smooth flow volume of an adjustable pulsation dampener. Adjustable pulsation dampeners are more adaptable, but require monitoring and maintenance.

I recommend: CAT PUMPS provides an easy to use tool for proper identification of dampeners and other pump accessories. Best Process Equipment sells and supports a full line of pulsation dampeners.

Increase the life of your pipes, pumps and valves with automatic pulsation dampeners

Automatic pulsation dampeners allow increased flow of air to balance the variations in pressure at each stroke. Automatic dampeners popularly used for fuel pulsation dampener applications are beneficial in application where constant pressure is desired. Automatic style dampeners use the systems non-wetted section to chamber and release air.

I recommend: Grainger is a pulsation dampener manufacturer as well as pumps and accessories. Fluid Energy Controls (FEC) builds and distributes pulsation dampeners for many applications.

Control high pressure pumping systems with chargeable pulsation dampeners

Chargeable pulsation dampeners use compressed air or nitrogen in a chamber to cushion the pulses within the line. Chargeable pulsation dampener manufacturers design for higher pressures and temperatures, making this method a good choice for large systems.

I recommend: Pulsation dampener suppliers Nova-Tech International manufactures a heavy-duty line of dampeners. Primary Fluid Systems is a pulsation dampener distributor with service and support for all your pumping needs.
