Abstract (en)
The new form of mono pump (1) has a stator (2) containing a rotor (3) mounted on bearings. The rotor is connected to a moulded coupling rod (5). This is contained by the suction casing (4) connected to the stator. The rod joins a connecting shaft (8) in the suction casing, which leads to the drive shaft connection, through the sealed casing (6). The rotor, coupling rod and connecting shaft are made as an integral, one-piece component in thermoplastic material. Preferably, a glass fibre-reinforced plastics material is used, especially polyamide 66 (RTM) or polytetrafluoroethylene, optionally with graphite filling.
