Principle of Operation

Flexible tubing, which conveys fluid from source to destination, is squeezed inside the pump head by rotating rollers against a rigid, crescent-shaped occlusion wall. The rollers induce suction in a gently pulsing rhythm. The occlusion is adjustable to increase pressure, or to decrease pressure for extended tubing life.

Each pump comprises a front panel with controls, a pump head with adjustable occlusion wall, a safety cover, a motor, a rigid case with four rubber feet, and a handle. The handle is practical both to carry the pump and, when rotated beneath the pump, to serve as a base that lifts and angles the pump face, making the controls even more easily user-accessible.
