NOTICE: The Texas weather emergency in February, in addition to the ongoing demand increase for pool products from the Covid pandemic, have caused industry-wide shortages on many products that most vendors expect to last late into 2021/early 2022. We're allowing items to be purchased so that customers who choose to wait will have their order shipped when product arrives. Many times there are long shipping delays on the few products we do have in stock. Please contact us to ask about availability. Live Chat and email are the best. Please keep trying back via chat and email as we can't answer them as fast as they come in but we are here, so keep trying! We're currently 14+ days behind on returning email (email is the best way to get a reply when all chat associates are busy).

Single Head Adjustable Output Pump
How It Works
Stenner’s adjustable metering pump 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 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.
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.
