Abstract (en)
[origin: EP2765311A2] The pump (1) has a pump housing (7) including an inlet opening (8) and a radial outlet opening (10). The housing includes a spindle packet (2) that receives a driving spindle (3) and a running spindle, where a pressure end of the spindle packet opens into a cavity (17) of the pump housing. The cavity extends in a longitudinal direction of the pump housing towards the same end of the pump housing at which the inlet opening and the outlet opening are arranged, where flanges (9, 11) are arranged at the inlet and outlet openings, respectively.
