Abstract

1,228,093. Peristaltic pumps. POLYMETRON CORP. Ltd. Oct.14, 1969 [March 21, 1969], No.50330/69. Heading F1F. In a peristaltic pump for conveying liquids in chemical apparatus in which a number of mechanicallyoperated plungers 10 operate in sequence to force the contents of one or more hoses 2 therealong from an inlet to an outlet, a layer 8 of flexible material, e.g., P.T.F.E. reinforced with glass-fibre is stretched in tension between the plungers and the hoses to lengthen the life of the hoses. The layer 8 is secured to the pump body 1 at one end by fixing means 9 and at the other end is secured to a spring 20.
