The electromechanical Classic Single Head Fixed Output Injection Pump works well with controllers.

The Single Head Fixed Output Injection Pump is one of four types in Stenner's Classic Series. This peristaltic metering pump injects solutions at a fixed rate and can be activated by a water meter for proportional feed for drinking water disinfection for animal health or homeowners. It can also be installed with a controller for sanitizing a swimming pool. Great news for installers in the commercial pool industry, the Classic Series single head fixed pump has been tested by ETL to conform to the ANSI/NSF standard 50 when used with ANSI/NSF 50 listed controllers. Additional applications include pH control, oxidation, corrosion and scale control and more.

The pump is also a component of Stenner’s pre-assembled panel system known as the Proportional Injection System. The Proportional Injection System doses solution that is proportional to a water system’s flow rate based on the water volume. A water meter sends a signal to Stenner’s PCM (Pump Control Module) which actuates the fixed output pump. The system is suited for constant pressure (variable speed) well pumps, poultry and livestock houses, irrigation and systems with demand based backup wells and any application with varying flow rates. If a pre-assembled system isn’t your preference, the pump, PCM and water meter are also available separately. Refer to the chemical resistance guide to determine the compatibility of the wetted components with the solution you want to pump or Contact Us.

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 two detachable components; the motor and the pump head that can be separated without tools.

How the Single Head Fixed Output Injection Pump Works

The output is not adjustable and is determined by the rpm of the motor gears and the size of the pump tube. The motor’s output shaft rotates at a fixed rpm which drives the roller assembly within the pump head.

Sub-series

The 45 and 85 models are two sub-series within the Classic Series Single Head Pumps (Adjustable and Fixed) and below is a summary of the primary differences in the Fixed models.

exclamationNOTICE: The information within this chart is solely intended for use as a guide. The output data is an approximation based on pumping water under a controlled testing environment. Many variables can affect the output of the pump. Stenner Pump Company recommends that all metering pumps undergo field calibration by means of analytical testing to confirm their outputs.
