Proportional Dosing | Proportional Injection System
The Proportional Injection System is for applications with varying flow rates, variable speed well pumps, poultry and livestock houses, irrigation and installations with demand based back-up wells.
For metering applications with varying system flow rates, select the Stenner Proportional Injection System.
The Proportional Injection System doses solution that is proportional to the water system's flow rated based on water volume. The system is designed to provide the essential metering components in an all inclusive package where the products are mounted at the factory on a heavy duty panel to affix to a wall. Built in to the panel is a compartment that keeps the cords and wires hidden for an organized aesthetic appearance. PVC union connections are included allowing easy installation and system service.
The primary components are the Classic Series single head fixed output pump, the PCM and a 3/4" plastic, lead free, dry contact water meter. The water meter sends a signal to the PCM (pump controller) which actuates the metering pump. The 3/4" plastic water meter is certified by IAPMO to ANSI/NSF 372, low lead and is offered in 1, 2 or 4 pulses per gallon. The system is equipped with a spin down filter, 3/4" white suction and discharge line and a flow indicator. Stenner's flow indicator is installed in the discharge line to provide a visual reference your solution is pumping.

100 psi (6.9 bar) maximum
NOTE: Injection check valve included with pumps rated 100 psi (6.9 bar) maximum.
|NOTICE: 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.|
