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.

The 85MHP5 Stenner Chemical Feed Pump Low Pres. (5 GPD) is available in 220v / 50 Hz or 250v / 50 Hz models.  The 250v / 50 Hz model pump / tank system can be found under model number S1G45MJL5D5S on our website.  The 220v / 50 Hz model would be a special order item so please call us if you would like to order one.

Are the Stenner pumps NSF approved?

Per the manufacturer, their adjustable pumps (not fixed rate) are NSF approved.   This would include the model 85MHP5 which is adjustable.

is the 26-100 psi the pressure of the treated water available at the output of the system for use? What is the 5 gal/day?
 Reply

Mike, The 26-100 PSI refers to the PSi that the injector check valve can handle as far as the source it is treated. The 5 gal/day refers to the max dosage of what you would like feeded into the body of water.
