Abstract

The diaphragm pump comprises pumping sections (12). Each pumping section comprises a cylinder (7), a pumping piston (11), a pressure chamber (15) adapted to contain hydraulic oil and subject, in use, to pressurization by movement of the pumping piston. Each pressure chamber (15) is separated from a water-containing pumping chamber (16) by a rubber diaphragm (17). The pumping sections are mounted within a housing. Each housing having a hollow cylindrical cavity in which each pumping section is inserted. This provides for a compact construction for the pump.
