Abstract

A rotor, or "impeller", for a pump of the flexible-vane type has an outer element 5 made of an extruded or injection moulded flexible and resilient thermoplastic material that is resistant to relatively high temperatures eg. 150 DEG C. The said material may be an olefinic elastomer; and a removable sleeve 4 may be made of stainless steel or an epoxide resin. Alternative modes of sleeving the impeller are described with reference to Figures 5 and 6 and Figures 7 and 8 (not shown). The working fluid of the pump may be one comprised in the manufacture of a beverage, a connectible substance eg. jam, or a pharmaceutical material. <IMAGE>
