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.
Stenner 85MHP17 Chlorine Injector for Well Water
The Stenner 85MHP17 is an adjustable peristaltic chemical feed pump and the model most often used for chlorine injection on private wells. It doses chlorine, hydrogen peroxide, or soda ash into the water line only while the well pump runs, so the chemical feed tracks water use. Its peristaltic design keeps the chemical inside the pump tube: it self-primes up to 25 feet and won't vapor lock or lose prime. This NO TANK version is the pump on its own for buyers who already have a solution tank. See all injection pumps for complete packages and parts.

What Stenner Pumps Are Used to Inject
Stenner pumps handle chlorine injection for wells with iron, hydrogen sulfide or bacteria problems, hydrogen peroxide for sulfur odor, and soda ash for acidic, low-pH water. Snap-fit components make the pump easy to service, and the chemical compatibility chart below shows which chemicals suit the standard tube material.
Building a Complete Stenner Chemical Injection System
The pump is one of four parts in a Stenner chlorine injection system. Each part does a separate job, and skipping one is the most common reason a chlorination setup underperforms.
Solution Tank
The solution tank holds the diluted chemical the pump draws from. This NO TANK listing doesn't include one; if you need both, the Stenner Injection Pump 85MHP17 & 15 Gal. Solution Tank pairs them.
Mixing or Retention Tank
Chlorine needs contact time to react with iron, sulfur, and bacteria. A mixing or retention tank installed after the injection point provides that time before water reaches your filters.
Carbon Filter
After the retention tank, a backwashing filter or carbon filter removes the precipitated iron and the excess chemical. Whole house catalytic carbon systems are a common final stage for chlorinated well water.
Wiring to Your Well Pump Power
The simplest installation powers the pump from the well pump circuit, so it only runs when the well pump runs. Install an outlet near the pressure tank and injection point, wired from the well pressure switch so the outlet is live only when the well pump kicks on, then plug the pump in. Match the pump voltage, 110V or 220V, to the power available at the pressure switch.
You can inject before or after the pressure tank. The order then runs injection point, retention tank, then backwashing or carbon filters.
Wells with variable-speed pumps don't give a steady on/off signal, so dosing won't stay consistent this way. Those wells need the Stenner Proportional Injection System.
Maintenance: Pump Tubes and the Injector Check Valve
The pump tube and the injector check valve are the Stenner pump injector parts that wear with use. AFW stocks Stenner Replacement Tubes #2 - 2 pack, the Stenner injector check valve 1/4", and the Stenner HPACK-2 accessory kit with #2 tube, suction parts, and injector parts, so a worn part is a quick swap rather than a new pump.
