No Need For Pulsation Dampeners
31 October 2012
The multi-diaphragm arrangement of the Hydra-Cell metering and dosing pump is claimed to remove the need for pulsation dampeners in many circumstances.
Pulsation in a hydraulic system is invariably caused by the pump – specifically, a reciprocating, positive Pulsation is usually observed as noisy vibration in system components or rapid gauge fluctuation but can be influenced by the harmonics of individual components within the system. This vibration can be a major problem, potentially causing component failure through fatigue or simply leakage in discharge pipe work due to pipe strain.
Hydra-Cell pumps from Wanner have multiple, hydraulically balanced diaphragms that operate sequentially, dramatically reducing system pulsation and damage it causes. The cost of additional pulsation dampeners is avoided in many instances and systems become more reliable.
