100DM5, Stenner Peristaltic Pump, Stenner Chemical Feed Pump, Stenner Metering Pump
Stenner Pumps 100DM5 adjustable chemical feeder is built with four detachable components: the motor, feed rate control, and two pump heads. 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 Stenner 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 heads. 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.
