ABSTRACT:
A peristaltic liquid pump in which a box-like housing encloses a rotatable head carrying a pair of rollers which engage a U-shaped portion of plastic tubing carrying liquid to be pumped. The housing has a light-transmissive cover member enabling the operator to view the tubing therein. A membrane is interposed between the rollers and the U-shaped portion of the plastic tubing, with the membrane having a relatively stiff surface for contacting the rollers and a relatively sticky surface for contacting the plastic tubing.
