Pulsation dampers for double diaphragm pumps – process stability and protection for your systems
Pulsation dampers help to reduce pressure fluctuations in the pumping process and ensure a more consistent supply stream. They relieve stress on piping, fittings and downstream components, and contribute to smoother, more stable system operation. They are a particularly useful addition in applications with double diaphragm pumps where pulsation-induced pressure peaks need to be minimised and sensitive processes better protected.
Why pulsation dampers are useful in pumping processes
Due to their design, double diaphragm pumps operate with pulsating flow behaviour. In many applications, this is not a technical issue. However, in sensitive processes or where pipelines are long, the resulting pressure fluctuations can lead to instability in the system, additional stress on components or uneven flow.
Pulsation dampers help to reduce these fluctuations and stabilise the delivery process. This allows piping systems to be subjected to more uniform loads, reduces mechanical stress and provides better protection for downstream components. This is particularly relevant when process stability, repeatability or smooth system operation are paramount.
The benefits of pulsation dampers
- More consistent supply stream
Measurement accuracy and process stability are improved. - Reduced pressure peaks
Pressure fluctuations in the piping system are effectively reduced. - Less pipeline vibration
Material wear and the risk of leakage are reduced. - Greater process stability
