A pulsation damper for a pumped liquid system has a housing with two axially identical hollow halves which, when joined at their flanges, form a substantially cylindrical cavity. Each housing half has a port on its longitudinal axis for fluid communication with a liquid chamber and a gas chamber defined by a flexible non-porous member. A pressurizing valve is provided, in a manual embodiment, for manually increasing or decreasing pressure in the gas chamber. An automatic pressure compensator is provided in an automatic embodiment and is so sized and configured as to be insertable and removable from the housing of the pulsation damper through the port on the end of housing. Provision is also made for modularly adding volumes of air to increase the effective gas chamber volume. |
