Stenner 45M4 Series single head adjustable output pump for low pressure (up to 25psi) applications.

Stenner Classic Series metering pumps are self-priming and the 3-point roller assembly provides a positive 2-point seal on the pump tube at all times. This eliminates the need for anti-siphoning valves and diaphragms. The patented mechanical feed rate control (adjustable models) allows the pump's output to be scaled from 5% to 100% with the simple turn of the dial.
