Claim:
1. A screw spindle pump for pumping fuel, oil and crude, comprising an inlet through which fuel is suctioned, an outlet, a drivable spindle and two follower spindles, wherein the drivable spindle and the two follower spindles are provided at a mutual angle to each other, and wherein the inlet is provided on a front side of the pump and the pump is provided on a rear side with a motor and wherein the angled relationship between the drivable spindle and the follower spindles allows the pump housing to be smaller than that of a conventional pump having a drive shaft and spindle shafts lying in one line, such that the screw spindle pump is adapted to be introduced into a liquid conduit for use as a submersible pump and wherein the pump further includes a pipe encasement seal which surrounds the pump and prevents leakage of suctioned fuel between the pump and the liquid conduit.
