Abstract
A peristaltic pump is disclosed having two identical hingedly connected housing sections defining mating surfaces substantially coplanar with the hinge axis and the longitudinal axis of the housing to facilitate easy opening of the housing sections for loading and manipulation of a flow tube looped internally of the housing and cooperable with rotatable displacement means to effect a peristaltic pumping action on the tube. Various pump mounting arrangements are disclosed which are particularly suitable for limited access areas and which maintain the pump sections in closed positions while facilitating quick release of the pumps for servicing and the like.
