Single Head Fixed
Electromechanical peristaltic metering pumps
For over 69 years, the versatile Classic Series remains a popular choice for installers. The pump is easy to install, service or convert to another model without purchasing another pump. Injection can be directly into the water line and can also be activated by a pressure switch or controller.

The Single Head Fixed Output pump is one of the varieties in the Classic line.
The fixed output pump is the same as the adjustable pump without the adjustability. The 45 models run at 26 RPM and the 85 models run at 44 RPM. The output is fixed and is controlled by the rpm of the motor gears and pump tube size. The motor output shaft rotates at a fixed rpm which drives the roller assembly within the pump head. The fixed output pump is compatible with controllers.
The pump is also a component of Stenner’s pre-assembled panel system the Proportional Injection System. The Proportional Injection System doses solution proportional to a water system’s flow rate based on the water volume. A water meter sends a signal to Stenner’s PCM 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.

Notice: The information within the charts above 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
