Abstract

The invention relates to a damper device for a piston pump. The device includes a partly air-filled, upright tube placed on the inlet conduit of the piston pump, and a partly air-filled, upright tube placed on the outlet conduit of the piston pump. The two upright tubes are interconnected with each other by means of a tube on which a shut-off valve is disposed. Each of the upright tubes is connected to a blower valve, respectively. Both of the blower valves are connected to a common compressed air source. The damper device may be adapted in a simple manner for aseptic operation and/or elevated product pressure.
