What are pulsation dampeners?

The pulsation dampener serves to reduce pulsation produced in operation and to assure stable discharge flow and pressure. PRINCIPLE OF OPERATION. When pulsations occur with pump operation, it will result in the pressure in Chamber B being greater than that in Chamber A.

Why pulsation dampeners are used?

Pulsation dampeners absorb the energy from the pulse wave created by a positive displacement pump, much like a shock absorber on a vehicle. Absorbing those pulse waves protects pipe welds and supports, and system components from damage due to pressure or excess movement.

How do pulsation dampeners work?

A pulsation damper works thanks to the same compressed air that feeds the pump. The compressed air introduced into the counter-pressure chamber behind the membrane creates a pneumatic damping cushion that self-adjusts according to the stress exerted by the pressure pulse of the fluid generated by the pump.

Which is the best pulsation dampener for pumps?

BLACOH is the industry standard for dampening the pulsation created by positive displacement pumps. They have been in business for more than 30 years, providing smooth fluid flows for pumping systems all over the world.

How are pulsation dampers and accumulators used?

The Hydropneumatic Accumulators and Pulsation Dampers from SAIP can be used in a variety of technical applications; the most important are: The accumulator is used in cases where the pump circuits need a big flow of oil in a short period.

How does the tapflo pulsation dampener work?

The Tapflo pulsation dampener works actively with compressed air and a diaphragm, automatically setting the correct pressure to minimize the pulsations. The active pulsation dampener is the most efficient way to remove pressure variations on the discharge of the pump.

What’s the difference between pulsation dampener and back pressure valve?

This patented design is a combination between a pulsation dampener and a back pressure valve, giving you twice the functionality with half of the footprint and leak points. Learn more and take a look at the performance graphs to see the difference. LOOKING FOR MORE? Sometimes bigger problems require bigger solutions.
