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.
