<p>A peristaltic pump is described in which a pumping tube is continuously and cyclically pressed against a wall of a pumping chamber by two rollers carried on a drive module driven by a drive shaft, characterised by the fact that the drive module consists of two half-arms, each of which carries one of the rollers at its end and at the other end is fitted with means for fixing it to the drive shaft, the arrangement being such that the half-arms are connected together and to the drive shaft for normal operation of the peristaltic pump while they can be separated from each other and the drive shaft for maintenance of the pump. <IMAGE></p> |
