Product details

The Stenner 45MFL5A1SUAA is a Classic Series single head peristaltic metering pump with fixed output. It runs on 120 V, delivers up to 50 gallons per day against 25 PSI, and uses .25 inch tubing.

How it injects

A peristaltic pump moves solution by squeezing it along a flexible tube with a roller. The chemical never contacts the pump mechanism, which is what lets one pump handle aggressive solutions and makes servicing a matter of changing a tube rather than tearing down a head.

Where it is used

Fixed output means it doses at a set rate whenever it runs, so control comes from what switches it on. Wired to a water meter it feeds in proportion to flow, which suits drinking water disinfection and animal health work. Wired to a controller it feeds sanitizer to a swimming pool on demand.

Questions and answers

What people ask about this product, answered by our pool techs.

Is the output adjustable?
No. This is the fixed output model, so it injects at a set rate. Adjustable models are a different part number.
What are the ratings?
120 V, up to 50 gallons per day, against 25 PSI, using .25 inch tubing.
Can it be used on a swimming pool?
Yes. Installed with a controller it feeds sanitizer to a pool. It is also used with a water meter for proportional feed in drinking water disinfection and animal health applications.
How does a peristaltic pump work?
A roller squeezes the solution along a flexible tube. Because the chemical never leaves the tube, the pump body stays clear of it, and servicing usually means changing a tube rather than rebuilding the pump.
