The attached photos represent a Stenner Single Head Adjustable Output Pump 85MHP40 being sold as is with the understanding that we sell quality products and equipment that operate as intended unless otherwise stated. Please review my feedback to see that I have a solid record.
Stenner Pumps 85MHP40 adjustable chemical feeder is built with three detachable components: the motor, feed rate control, and pump head. Outputs are dependent upon three factors: the rpm of the motor gears, the percentage setting on the feed rate control, and the size of the peristaltic pump tube. All of Stenner Pumps chemical feed pumps have a 3-point roller design in the pump head, which acts as a check valve to prevent back flow, siphoning, overdosing and loss of prime
The motor shaft rotates at a fixed rpm which drives the adjustable feed rate control to intermittently engage the roller assembly within the pump head. The chemical solution in the pump tube is captured between the rollers as they rotate and compress the tube. As the rollers advance, the squeezed tube section regains its original form and generates a vacuum, creating the self-priming feature that delivers a constant flow unaffected by the outlet pressure.
