Page 13: Description
Diaphragm pulsation damper Description 3. Description General Piston and membrane metering pumps produce pressure variati- ons in the discharge line. Diaphragm pulsation dampers are used to flatten the pressure peaks and to reduce the pressure variati- ons. The diaphragm pulsation dampers with separating diaphragm de- scribed here do not exceed the limit described in the pressure equipment directive (PS x V = 25 bar x liters). -

Page 17: Installation
Diaphragm pulsation damper Installation 4. Installation Mounting In order to dampen pressure peaks and pulsations perfectly dia- phragm pulsation dampers have to be installed correctly. There- fore it is necessary to mount them very close to the point where pressure peaks are produced. For metering pumps, this place would be right after the discharge valve, using a tee-fitting or direct flow through the diaphragm pul- sation damper. -
Page 18: Filling
Diaphragm pulsation damper Installation Filling Warning! Danger of ignition Use air for filling the diaphragm pulsation damper. Never use oxygen! The diaphragm pulsation damper is most effective if the initial pressure is about 0.6 times the final average operating pressure. It is suitable to have a pressure gauge permanently installed at the diaphragm pulsation damper (W3T158497). -
