The pump includes a stator (1,9) and rotor (2) supported within the stator by means of two roller bearings (6,8). At least one of these bearings (8) acts against a section of the stator in order to serve as an axial stop for the rotor (2). This bearing support is a flexing type support and not a shearing or cutting type support. The surface against which this bearing is supported may be a single circular surface, or may be a number of support bars which are able to flex. The pump assembly has a mass of 250g, including its rotor and has a nominal speed of 60,000 turns per minute. Axial vibratory resonance of the device is 30,000 turns per minute. |
