Main specification DELLMECO DME Active Pulsation Dampeners are specially designed to be used along with DELLMECO Electro- Mechanical Operated Double Diaphragm Pumps of all Plastic, Metal and Hygienic range. A general aspect to be considered is that a pulsation dampener decreases the total capacity of the system depending on the point of operation.
  • Page 51 Before putting the pump and the dampener back into operation, the tightness of both (i.e. housing bolts) has to be checked.  DME Series Pump with installed PDEM Pulsation Dampener obligatorily has to be equipped with safety device (Push-Button Switch or Pressure Relief Valve). For more information, please refer to Chapter 4 (page 6).
