Used but in excellent working condition. All pumps were taken apart, cleaned, and re-greased and work as new. Stenner 85MHP40 single head adjustable output pump for high pressure (up to 100psi) 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 allows the pump's output to be scaled from 5% to 100% with the simple turn of the dial.
