PCM – Pump Control Module

PCM – Pump Control Module From Stenner

The PCM (Pump Control Module) is a time adjustable controller that powers a fixed output pump. It operates with a pulsing dry contact water meter that sends a signal to the PCM which actuates the pump to deliver the desired dose based upon water volume. It is one of the components in the Proportional Injection System that also includes the Classic series single head fixed output pump and a 3/4" plastic water meter pre-installed on a heavy duty panel. Purchasing the items separately offers flexibility with the water meter selection; available in plastic or Eco Brass with variety of sizes and pulse rates, to customize your own proportional feed installation.

Unique Stenner Features

The PCM operating time range is factory set according to the specific model selected, but it can be converted to any of the other available time ranges, so it is not necessary to purchase another model. The time range is converted by changing the position of the jumpers on the printed circuit board located under the PCM’s cover. The PCM Manual contains the instructions.
