Stenner S3N85MJH1A1S  is a single head adjustable pump system is perfect for accurate and repeat injection of chemicals or liquid. This pump is built with three detachable components: the motor, feed rate control and pump head. All Stenner pumps have a 3-point roller design in the pump head, which acts as check valve to prevent back flow or loss of prime. The motor 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. This system comes pre-assembled for quick and easy installation.
