Abstract (en)
[origin: EP0334189A2] The rotor (G) consists of a circular body (C) which has on its circumference (G) flexible radial paddles (R). Through the centre of the rotor is a hole (F) in which there is a dividing web (D). The rotor is pressure moulded in one operation in an elastomer material, and is housed ina pump housing (P). The rotor (G) is driven by a motor (M) via a coupling (T) and a shaft (A). The end of the shaft is slotted (K) so that, when inserted into the hole (F) in the rotor, the web (D) engages in the slot (K), thus enabling the rotor to be driven.
