Pulsation Damper

Pulsation Damper

Pulsation dampers are liquid pressure vessels that is to slow down the impulse hunting of
liquid medicine discharged from metering pump. There are mainly three types of pulsation
dampers: Air Pulsation Damper,Diaphram Pulsation Damper, Bladder Pulsation Damper. The
pulsation cuased by the metering pump can be effectively reduced up to 95% with the suitable
damper size installed in the pumping system.

It contains a composite PTFE diaphragm that separates an inert pressurized gas (air or
nitrogen) from the pumped liquid. The size diaphragm pulsation damper should be 10 times
of each metering pump stroke capacity at least.
