Abstract
A screw spindle pump for the delivery of fluid media with a pump housing having an inlet channel with a first longitudinal axis, an outlet channel with a second longitudinal axis, a first drive spindle with a third longitudinal axis, and a second driven spindle. The spindles each include a profiled section between the inlet channel and the outlet channel, wherein the profiled sections of the spindles are engaged at least partially with one another and form, with the pump housing between the inlet channel and the outlet channel, a delivery section parallel to the longitudinal axis of the drive spindle with delivery chambers for the fluid medium. The second longitudinal axis of the outlet channel is disposed at an obtuse angle to the delivery section in the pump housing. The invention also relates to a method for operating a screw spindle pump.
