A DAMPER DEVICE FOR A PISTON PUMP

摘要

The invention relates to a damper device for a piston pump. The device includes a partly air-filled, upright tube (1) placed on the inlet conduit (2) of the piston pump, and a partly air-filled, upright tube (3) placed on the outlet conduit (4) of the piston pump. The two upright tubes (1, 3) are interconnected with each other by means of a tube (5) on which a shut-off valve (6) is disposed. Each of the upright tubes (1, 3) is connected to a blower valve (7, 8), respectively. Both of the blower valves (7, 8) 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.
