Online Auction Description
Stenner proprtional injection system provides reliable dosing for applications unable to connect directly to a well power supply.

Product Features

Proportional Injection

Provides injection based on water flow for applications unable to wire directly to the well pump.

Complete system

Flushable Prefilter
Water Meter
Pump Control Module
Fixed Output Pump
15 gallon solution tank

Pre-assembled Panel

Simplifies installation to inlet and outlet connections and provides a clean look.

Multiple Uses

Capable of injecting a wide range of solutions and can be used for numerous different applications - pH correction, bacteria treatment, and iron/manganese/hydrogen sulfide (rotten egg odor) oxidation.


Self-priming up to 25 feet and will not vapor lock or lose prime

Multiple configurations

Available with different flow rates, operating ranges, and pulse rates to fit every situation.


Comes with 110V power supply.

Product Description

Proportional Injection - Injection pumps are widely used for chlorine or soda ash injection and ideal for just about any chemical injection application. While stand alone pumps require direct wiring into the well switch, the proportional injection system can be used anywhere, expanding the treatment possibilities.

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 Stenner injection pump!

Pre-assembled panel - The proportional injection system has all major components pre-assembled and connected to a durable polyethylene panel for convenient wall mounting. The panel includes a section that contains the cords and wires, keeping everything neat and organized. NOTE: The included 15 gallon solution tank is not mounted.

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.

Configuration Help

REQUIRED INFORMATION To properly configure your injection system you will need the following information.

Maximum Flow rate - The maximum flow the system will be treating in gallons per minute. For proportional systems this will be the maximum demand the application may use. A simple way to test is to fill a bucket (5 gallon is a common size) at the install point and time how long it takes to fill up. If a direct reading from the install point is not possible, measure the largest spigot (such as a garden spigot) as close to the install point as possible. Divide the time it takes to fill the bucket (in seconds) by 60, then multiply by the size of the bucket (in gallons) to get your GPM. Example: If it takes 35 seconds to fill a 5 gallon bucket -
37.5/60=1.6br> 1.6*5=8
Your flow rate would be 8 GPM.

Solution strength in parts per million (ppm) - This is the concentration of solution you are injecting. This will depend on what you are using and the mixing ratio. Be sure to check your labels. A few examples:
CHLORINE - Standard Chlorox bleach is 5.25% sodium hypochlorate, providing a full strength solution of 52,500 ppm. If you use a solution that is 9 parts water and 1 part bleach, your final strength is 5,250 ppm.
HYDROGEN PEROXIDE - Readily available hydrogen peroxide is 7% strength, providing a full strength solution of 70,500 ppm. If you use a solution that is 9 parts water and 1 part bleach, your final strength is 7.000 ppm.
SODA ASH - 4 lbs of soda ash powder dissolved into 5 gallons of water provides a 10% solution, which is 100,000 ppm.

Dosage in parts per million (ppm) - This is the total ppm of solution you are wanting to inject in the water. This will depend on the water you are treating and what you are using. General guidelines:
CHLORINE - For each ppm of iron add 1 ppm to your dose, for each ppm of manganese add 2 ppm to your dose, and for each ppm of hydrogen sulfide add 3 ppm to your dose
HYDROGEN PEROXIDE - For each ppm of iron add 0.5 ppm to your dose, for each ppm of manganese add 1 ppm to your dose, and for each ppm of hydrogen sulfide add 1.5 ppm to your dose
SODA ASH - Dosage will vary depending on water chemistry, but usually falls in the 100-200 ppm range.


Pump Size - To calculate output requirement, multiply your maximum flow rate*dosage*1440, then divide by solution strength in ppm. For example, if your maximum flow rate is 8 GPM, using a 15ppm dosage of chlorine and a 5,250 ppm solution:
8*15*1440 = 172,800
172,800/5,250 = 32.9
Your required output would be 32.9 gallons per day, so you would get the next higher up pump, or the 40GPD in this case.

Meter Pulse Rate - Meter pulse rate per gallon is expressed as contacts per gallon (cpg) and is used to determine the operating time on the PCM. In general the 1 pulse per gallon is used for flows less than 5 GPM and the 2 pulses per gallon is used for more than 5 GPM, with 4 pulses per minute used in special applications.

PCM Operating Time - To calculate PCM operating time, first calculate you available dose time. Divide 60 by the maximum service flow rate, then divide the result by the contacts (or pulses) per gallon (cpg) of your meter. Multiply your available dose time by the pump output requirement, and then divide that result by the pumps maximum output. If you have a meter with 2 cpg, a flow rate of 8 GPM, a required output of 32.9 GPD and are using a 40 GPD pump:
7.5/2=3.75 available dose time
The pump operating time would be 3.08 seconds, so you would select any of the operating times that covered 3.08 seconds.
