3 FAQs about pulsation dampeners

If you've got an Air operated double diaphragm pump in your system, odds are you might be experiencing some sort of pulsation resulting in the rattling and vibration movement in the pipes and system? A pulsation dampener may be a great choice for diaphragm pumps to get a steady flow.

WHAT DOES A PULSATION DAMPENER DO?

Pulsation dampeners absorb the energy from the pulse wave created by a diaphragm pump, more like a shock absorber in a vehicle. Absorbing these pulse waves protects pipe welds and supports the system components from damage due to pressure or excess movement.

HOW DOES A PULSATION DAMPENER WORK?

As the pulsating flow enters the dampener vessel, the air pocket trapped above the fluid absorbs up to 80% - 90% of the pulsation, allowing a laminar or smooth flow downstream the dampener.

WHERE ARE PULSATION DAMPENERS COMMONLY USED?

Pulsation dampeners are commonly used wherever an AODD pump discharges flow in an unsteady manner, and where the pulsation may result in damage to the piping system. Diaphragm pumps typically benefit from a pulsation dampener. The type of pulsation dampener used is typically defined by where they are placed in the system, and what they need to do. For example, "pulsation dampeners" are placed on the discharge of the pump, "inlet stabilisers" are on placed before suction of the pump, and an accumulator or "surge suppressor" is used next to a valve or other device that restricts the flow in a system.
