Electro-Mechanical | Classic Series | Double Head Fixed 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.
6.0 to 170.0 gpd up to 25 psi
6.0 to 34.0 gpd up to 100 psi
The Double Head Fixed Output, another variation to select from in the Classic Series, electro-mechanical pump line.
If requiring more output than the Classic single head pump offers, especially with 25 psi installations for larger commercial swimming pools, then the double head pump may be your answer. Similar to the other models in the Classic series, the 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. Also utilized in water and wastewater treatment plants, the pump can inject two compatible liquids at the same ratio. The Classic Series double head fixed pump is built the same way as the single head fixed with the addition of another pump head that doubles the output. The pump runs at 100% fixed rate and can be installed to an ORP type controller to manage the output.
Unique Stenner Features
- Interchangeable pump heads and tubes to convert one model to another without having to purchase a new pump.
- Easy and fast tube replacement without tools with the QuickPro® pump head.
- The pump is built with three detachable components; the motor and two pump head that can be separated without tools.
How the Double Head Fixed Chemical Injection Pump Works
The fixed rate pump does not have an output adjustment. The output is determined by three factors; the rpm of the motor gears and the pump tubes in both heads. The motor’s output shaft rotates at a fixed rpm which drives the roller assembly within the pump head.
The 100 and 170 models are two sub-series within the Classic Series Double Head Pump (Adjustable and Fixed) and below is a summary of the primary differences in the Fixed.
