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. 45 Series pumps eliminate the need for anti-siphoning valves and diaphragms. Stenner's fixed output metering pumps are built with two detachable components: the motor and pump head. Outputs are dependent upon the rpm of the motor gears and the size of the peristaltic pump tube.
