Abstract

A hose or peristaltic pump comprises a hose (1) resting against an abutment (2) and at least three plungers arranged and driven substantially perpendicularly to the length of the hose. Two plungers (4, 5) are operated as valves and the third plunger (3), arranged between the two valve plungers, is operated as a conveying plunger whereby a substantially accurate dosing is accomplished, especially if the plungers do not completely squeeze the hose together and also do not completely relieve the hose from the plunger action on the return stroke. <IMAGE>
