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 models are available if different outputs are desired.

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.
