PROGRAMMABLE PUMP 24-HOUR OR 7-DAY
Stenner’s adjustable 24-hour metering pump is built with a low rpm motor and a detachable pump head, universal to all Stenner pumps. The BDF pump has a fixed rpm motor which is activated by dip switches to inject scheduled daily doses of chemical. The pump can be programmed to activate hourly from 1 to 24 events per day. 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’s output shaft rotates at a fixed rpm which drives 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.
