TPU DP Adjustable RPM pump

Peristaltic pump designed to move liquids of low to high viscosity from source to destination at user-set speeds from 0 to 60 RPM. The easily accessible controls provide for Priming, dynamic Braking, setting RPM, and Reversing Flow direction. There is also a Power LED.The DP model has the added benefit of a programmable timer.

The timing device permits dispensing over a selected period of time as either a single volume of liquid dispensed every time the pump is activated according to the user’s settings, or via remote input through the “D” connector at the rear of the pump. Seven time periods are possible: 0.1 – 1 sec., 1 – 10 sec., 6 – 60 sec., 1 – 10 min., 6 – 60 min., 1 – 10 hr., or 10 – 100 hr.

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.
