The Single Head Adjustable Output Pump is ideal for treating problem water by injecting solutions for pH control, to oxidize iron, manganese or hydrogen sulfide for filtration removal. It is ideal for use in water conditioning applications, industrial processes, wastewater and water treatment, and in cooling towers and irrigation, where it can be used to prevent Legionella. Because it can be used for disinfection, pH control, corrosion and scale control, and oxidation, it is also ideally suited for horticultural use, in the metal finishing industry, for commercial pool use for maintaining equipment and sanitizing swimming water.
Stenner Single Head Fixed Output Pump

The Classic Series Single Head Fixed Pump injects solution at a fixed rate. In addition to pH control, oxidation, corrosion and scale control, it can also be used in proportional dosing applications for drinking water disinfection, and used in conjunction with a controller for swimming pool sanitation, as it conforms with ANSI/NSF standard 50 when used with ANSI/NSF 50 listed controllers.
Stenner Double Head Adjustable Output Pump

The Classic Series Double Head Adjustable Pump is similar in build to the single head adjustable pump, with the addition of a second pump head which doubles output. The pump can inject two compatible solutions at the same ratio with solutions such as polyphosphates, acid, sodium hypochlorite, and biocides for applications such as disinfection, pH control, corrosion and scale control, sanitation, and oxidation. Because they provide twice the output, they are ideal for commercial pool and aquatic facilities and municipal wastewater and water treatment plants.
Stenner Double Head Fixed Output Pump

The Classic Series Double Head Fixed Pump can inject two compatible liquids at the same ratio. It is commonly used on large commercial swimming pools, wastewater and water treatment plants. It runs at a 100% fixed flow rate output and can be installed to an ORP type controller to manage output.
Stenner Econ FP Pump

The Stenner Econ FP Pump is a compact flow activated peristaltic pump ideal for light duty applications. It is ideally suited for drinking water disinfection or pH adjustment in residential or farm private water wells, and in animal health applications such as poultry hatcheries.
The wall-mountable, enclosed housing carries cULus for indoor and outdoor use. Pump must be mounted vertically for outdoor and wet environments, and mounting accessories are also available.
There are three operating modes accessible through the control panel: Seconds, Flow Switch, and Auxiliary and their optional percentage settings. To prevent tampering, the six-button, backlit LCD window requires two button operation and locks after 60-seconds of idle time.
It operates at 30 gpd, 25 psi, at a set time or speed, and is activated by dry contact signal or 12-24 VAC/VDC signal. It is flow activated from a water meter, control valve, flow switch, or from any other control equipment that can respond to flow. The Econ FP can inject solutions into water or disinfect water lines with acids, chlorine dioxide, or chlorine.
Advantages:
*No contact between solution and moving parts
*No valves required, allowing for easy maintenance
*No foot valve required. Self-priming against max working pressure.
*No lose prime or vapor lock
*It pumps off-gassing solutions and can run dry
*Back pressure not affected by output volume.
