Abstract

Improvements in helical pumps, with a pump body that contains the rotors and that is housed in a housing with openings for the intake and exit of the driven liquid, characterized in that the driven liquid is conducted between the housing and the body of the pump in countercurrent to the current direction in the pump body.
