Dampeners can also be placed at the pump inlet as stabilizers, improving NPSH conditions by reducing acceleration pressure losses caused by the opening and closing of the inlet ball valve.
Each dampener features a pressure chamber divided by an elastomeric bladder. The lower section holds the process liquid, while the upper section contains a pre-charged air cushion, carefully set to match operating conditions. During each discharge stroke, the bladder flexes into the air cushion, absorbing excess energy. On the suction stroke, the compressed air cushion forces the liquid back into the system, ensuring a steady, reliable flow.
