Abstract

A pump device for a flowable product comprising a housing (10) and at least two pair of connection pieces (12, 13) on the housing (10). One connection piece in each pair of pieces forms the inlet means to the chamber (16) and the other the outlet means. One pair of an inlet means and an outlet means are operatively interconnected via a sub-chamber forming, not pressure resistant, resilient, tube-shaped hose (11) in the chamber (16). Truncated, perforated, conical hose connection means (17, 18) are arranged at opposite ends of the elongated housing. Check valves (21, 22) of the flap type are arranged for alternatingly opening and closing the inlet and outlet of each pair of connection pieces. Means (24-27) are arranged for pressurizing the hose (11) either internally or externally for operating the pump such that it pumps the product either through the chamber (16) or through the hose.
