Abstract

Pump has eccentrically or concentrically positioned wheel operating centrifugally. It is driven only by a reaction medium under super-atmospheric pressure. Specif. this medium is fed in the centre at the circumference of the housing. Pref. the drive is a jet or turbo-mechanism. In a pref. arrangement use is specif. made of a PTFE seal.
