Displacement pump e.g. slurry pump, has pump unit comprising working areas, displacement elements designed as diaphragms, and piston for operating displacement elements, where pump unit is designed in double-acting manner
The pump has a drive unit, and a pump unit (2) comprising working areas (4, 4'). Displacement elements (3, 3') designed as diaphragms (6, 6'), and a piston (7) operates the elements, where the pump unit is designed in a double-acting manner. Cylinders (5) run parallel to each other at a reduced distance. The elements are rotated around an angle of 1 to 90 degrees. The working areas are connected with pressure pipes (17, 17') in pressure valve housings (14, 14'), respectively over a pressure valve and connected with a suction pipe (16) in a suction valve housing (15) over a suction valve.
