Abstract

1335069 Rotary pumps SNAM PROGETTI SpA 8 Oct 1971[8 Oct 1970] 47066/71 Heading F1F In a peristaltic pump comprising a rotor 9 having a number of rollers 12 engageable with a plurality of flexible tubes 24, each tube is located in a groove 27 formed in the arcuate inner face of a backing member 26, each member 26 being positioned independently relative to the rotor axis by one of a number of screw threaded pins 28 mounted in a further member 14 fixed to a base plate by bolts 15 and locking nuts 16. This enables the pump to operate with tubes of different diameters simultaneously and to compensate for wear in the tubes. Longitudinal movement of the tubes 24 is prevented by clamping them in apertures 22 or 23 formed between a fixed plate 18 and clamping blocks 19.
