For over 50 years, Stenner's time-tested peristaltic chemical injection pump offers consistency.
Self-priming against maximum working pressure, foot valve not required
Can run dry and does not clog from dirt and debris
Can pump off-gassing solutions without losing prime
Reproducible outputs within 2%
Sub-assemblies fit together without tools; easy service or conversion to another model

The Classic Single Head Fixed Output pump works well with controllers.
This peristaltic metering pump injects solutions at a fixed rate. It can be activated by a water meter for proportional feed for drinking water disinfection for animal health or homeowners or installed with a controller for sanitizing a swimming pool. Great news for installers in the commercial pool industry, the Classic Series single head pump has been tested by ETL to conform to the ANSI/NSF standard 50 when used with ANSI/NSF 50 listed controllers. Additional applications include pH control, oxidation, corrosion and scale control and more.

How It Works
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 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.
Stenner's fixed output metering pump is built with two detachable components: the motor and pump head. Output is dependent upon the rpm of the motor gears and the size of the peristaltic pump tube. The fixed rate pump has no output adjustment. The motor's output shaft rotates at a fixed rpm which drives the roller assembly within the pump head.
The self-priming peristaltic pump is also referred to as a hose, tube or dosing pump.
