Pulsation Dampener
KEEPING YOUR SYSTEM CONSISTENT
A pulsation damper is a common component for eliminating pipe pulsation and it is an accessory that must be provided for a metering pump system. WRS’s Pulsation Dampeners are designed to reduce pulsation and vibration in the pipe system that is caused by a metering pump or plunger pump. It ensures a smooth and continuous flow of the system. By removing the pulsation flows, the efficiency and accuracy of the pump system can be increase significantly. On the other hand, it helps to protect the pump, seals, gaskets of the entire systems from vibration and result in a longer lasting safer system. Compressed air or gas is introduced into the air chamber of the Pulsation Dampener to a specified pressure.
The gas is entrapped by the elastomeric bladder, which prevents contact between the process fluid and compressed gas. During pump discharge, fluid enters the wetted chamber of the WRS Pulsation Dampener, displacing the bladder, compressing the gas and absorbing the shock. During pump shift, liquid pressure decreases, the dampener gas expands, pushing fluid back into the process line. Whether a piston, plunger, air diaphragm, peristaltic, gear, or diaphragm metering pump a WRS Pulsation Dampener placed at the pump’s discharge will produce a steady fluid flow up to 99% pulsation free; protecting the entire pumping system from the damaging effects of shock.
