Abstract

The pump is of the type in which rollers roll over the hose thereby compressing it, and thus moving the liquid which has been drawn-in by the resilient expansion of the hose behind each roller. The elliptical or diamond-section hose has its small diameter engaged by the rollers whilst its large diameter is arranged along the side walls of the pump housing. The hose may have a longitudinal rib running along one, and projections on the other, small diameter side. A number of hoses may be arranged parallel to one another. The hoses may be arranged symmetrically relative to the rotor carrying the rollers.
