PROPORTIONAL INJECTION SYSTEM

Stenner Proportional Injection System delivers a chemical dose precisely matched to the water system’s flow rate, ensuring accurate injection based on total water volume. Engineered as a complete, ready-to-install solution, this system includes all key metering components pre-mounted on a durable, factory-assembled panel for convenient wall installation.

At its core, the setup features the Classic Series single-head fixed output pump, a PCM (pump control module), and a 3/4″ plastic, lead-free, dry-contact water meter. The water meter transmits signals to the PCM, which in turn activates the metering pump to maintain accurate proportional dosing.
