Programmable 7-day Timer Metering Pump - 25BDF4-7 BDF SERIES From Stenner
Programmable 7-day Timer Metering Pump
How It Works
Stenners adjustable programmable 7-day 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 daily from 1 to 7 days per week. 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 motors 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.

A rotating assembly of rollers compresses a flexible tube within a housing to create a vacuum to lift a chemical solution. The self-priming peristaltic pump is also referred to a hose, tube or dosing pump.
