Darbe Sönümleyici PDM / PDP

PDM and PDP pulsation dampers are membrane dampers with nitrogen (N₂) filling and a factory-preset preload pressure. By reducing the pressure pulses created by the dosing pump they protect pipework, fittings and instruments.

PDM models have a 1.4404 (AISI 316) stainless steel housing with EPDM or FPM diaphragm rated up to PN 180; PDP models use a PTFE diaphragm rated PN 20. PTFE versions are also suitable for chemically aggressive media. Volumes are 0.15 l and 0.3 l with a G 1/2" female connection.
