Product Description

Stenner Model 85MHP17 Pump - Widely used for chlorine or soda ash injection and ideal for just about any chemical injection application, the peristaltic design of the Stenner pumps eliminates the hassle of priming. The 85MHP17 model is advertised here and is the most commonly used model, however, other the other 45MHP & 85MHP models shown below are available for the same cost if different output ranges are desired.

Adjustable Rate - An external dial ring allows for easy adjustment of the final output. 42 marked positions control the output, providing as little as 5% all the way up to 100% of maximum output. Add that to an incredible accuracy of +/- 2% finding just the right setting has never been easier!

Self-priming up to 25 ft. - Stenner pumps utilize a 3-point roller assembly to "squeeze" the chemical through the pump tube. At any given time 2 points of the roller are in contact with the tube, creating a 2 point seal. This 3-point roller design allows the Stenner pumps to prime themselves up to 25 ft. In addition, the seal created prevents back flow and siphoning that are a common problem with diaphragm pumps. Say goodbye to vapor lock and the hassle of manual priming with a new Stenner injection pump!

Snap-fit Components - The Stenner Pump consists of 3 main components - the motor, the feed rate control, and the pump head. All three components lock together with a simple twist, making maintenance a simple, tool-free task. By using interchangeable parts, changing out components is as easy as twist and change!

Versatile Pump Tube Design - Stenner pumps use an FDA approved pump tube made of Santoprene® to deliver the chemicals. This allows for use with a variety of chemicals and separates the rest of the pump components from the often damaging effects of the chemicals, extending pump life. In addition, the tube design makes changing easy and interchangeable tube sizes allow for easy modification of pump output capabilities.

Please note: Wells with variable speed pumps will need the proportional injection system for consistent dosing.


Typical installation:

For simple installation of these type of pumps, it will be powered by your water well power supply. This way it only turns on and pumps into your water line when your well pump is on.  To connect to well power supply, you will install an outlet box close to well pressure tank and injection pump installation location. You will run wire from your well pressure switch to the outlet so the outlet is only on when your well pump kicks on.  Then you plug the injection pump directly into that outlet.  Make sure to choose 120v or 220v depending on your power supply available to connect to.

Order of installation would be, well pressure tank, injection pump injecting into your water line, you can inject before or after the well pressure tank. Then after the injection pump and after your well pressure tank, you will want to use a mixing or retention tank to give you the proper contact time of chemical and your water. From the retention tank, you will then go into any backwashing filters you have, or carbon filters to remove excess chemical.
