Electro-Mechanical | Classic Series | Double Head Adjustable Chemical Injection Pump
For over 60 years, Stenner's time-tested peristaltic pump offers consistency.
- Self-priming against maximum working pressure,
foot valve not required.
- Can run dry and does not clog from dirt and debris.
- Can pump off-gassing solutions without losing prime.
0.3 to 170 gpd up to 25 psi maximum
0.3 to 34 gpd up to 100 psi maximum
The Double Head Adjustable Output Pump is another variation to select from in the Classic Series, electro-mechanical pump line.
Similar to the other models in the Classic series, the Double Head Adjustable Output Pump will dose solutions such as sodium hypochlorite, acid, polyphosphates, biocides for common water treatment applications that include disinfection, pH control, corrosion and scale control, oxidation and sanitization. This pump series provides twice the output for large Commercial Pool and Aquatic Facilities or Water and Wastewater treatment plants. The pump can also inject two compatible solutions at the same ratio. The Classic Series double head adjustable output pump is built the same way as the single head adjustable with the addition of another pump head that doubles the output.
How the Double Head Adjustable Output Pump Works
The output is determined by three factors; the rpm of the motor gears, the setting on the feed rate control and the pump tubes in both heads. The feed rate control has an external dial ring that is labeled L to 10 offering an adjustable output of 5% to 100% in 2.5% increments.
Unique Stenner Features
- Interchangeable pump heads and tubes to convert one model to another; not necessary to purchase a new pump.
- Easy and fast tube replacement without tools with the QuickPro® pump head.
- The pump is built with four detachable components; the motor, feed rate control and two pump heads, that can be separated without tools.
The 100 and 170 models are two sub-series within the Classic Series Double Head Pumps (Adjustable and Fixed) and below is a summary of the primary differences in the Adjustable.
