The output is not adjustable and is determined by the rpm of the motor gears and the size of the pump tube. The motor’s output shaft rotates at a fixed rpm which drives the roller assembly within the pump head.

These pumps are ideal for slurries, abrasive, viscous and corrosive liquids because only the tubing is in contact with the solution.
