How It Works
Stenner pumps come as either adjustable or fixed output metering pumps. Each pump has detachable components: the motor and pump head is standard and
optionally a feed rate control on adjustable pumps. Outputs are dependent upon the rpm of the motor gears and the size of the peristaltic pump tube and
on adjustable models the percentage setting on the feed rate control. The fixed rate pump has no output adjustment. All Stenner metering 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.
Fixed Speed Pumps:
The motor's output shaft rotates at a fixed rpm which drives 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.
Adjustable Pumps: 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.0
