Stenner Adjustable Feed Pump (10 GPD, 100psi, 120v)

Stenner's Single Head Adjustable Metering Pump is built with three detachable components: the motor, feed rate control, and pump head. 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.


  • Self-priming up to 25 feet and does not lose prime
  • Can pump off-gassing solutions
  • Can run dry without damage
  • Adjustable feed rate control from 5%-100% in 2.5% increments
  • Pump tubes accept a variety of chemicals
