Abstract (en)
The screw spindle pump has a drive spindle and at least one running spindle. They are mounted in the recess of a housing between a suction chamber and a pressure chamber. The pressure-side profile run-out of the spindle (14) is conically turned at the OD (d) and the angle of inclination (w) of the conical surface (43) lies below 10 deg.
