Stenner 45M5 Classic Series Peristaltic Metering Pump - 120V - 1/4" - Fixed Head 45MFL5A1SUAA

Stenner 45MFL5A1SUAA Peristaltic Metering Pumps are based on a simple, well-engineered design that minimizes complexity and delivers reliable performance. The time-tested designed is renowned for consistent quality and ease of service, which increases dependability for users while reducing service time and expense.

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.
