1. GENERAL INFORMATION
1.1 General
Aalborg’s TPU and TPV model peristaltic pumps are designed
for safety and long life. They are economical, easy to load,
sturdy, and compact for a small footprint. Designed for use
with liquids of widely diverse viscosity, they are suitable for
laboratory, processing and OEM applications, even fuel with
the appropriate tubing.
CAUTION:
PERISTALTIC PUMPS, INCLUDING
MODELS TPU AND TPV, ARE NOT SUITABLE FOR USE
WITH BLOOD. THE ROLLER TECHNOLOGY CAN CAUSE
HEMOLYSIS.
1.2 Principles 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 pulsing rhythm. The occlusion is
adjustable on TPU models for increased pressure, or
decreased pressure to extend tubing life.
Each pump is comprised of a front panel with controls, a pump
head, a motor, a rigid case with four rubber feet and a handle.
