Schwingungsdämpfer, Pulsationsdämpfer PD III D aus PP für Druckluft Membranpumpe 1/4" und 3/8"
Pulsation dampener PD III D
for small systems and in laboratories
Description: The pulsation dampers are containers filled with a gas cushion. A diaphragm separates the gas cushion from the system fluid. Pulsation dampers store and discharge part of the stroke volume in the stroke rhythm of the double diaphragm pump, whereby the gas cushion is compressed or decompressed accordingly. This makes the pulsating flow rate of the pump almost uniform. Adjustable air control Materials: PP / PVDF / stainless steel Features & advantages Connection type on the medium side: 1/2" IG Connection type on air side: 1/4" AG Max. operating pressure 10 bar ensure an almost uniform volume flow, which increases the accuracy of flow meters Compensation of pressure surges (water hammer) protects installed fittings Prevents pipe vibrations that cause material fatigue and pipe breakages
