The Stenner tank system utilizes the Econ FP proportional flow pump. The system ships pre-assembled. The pump is mounted vertically on the tank and includes a rain roof for extra protection from the elements. The included pump can inject up to 16 gallons per day of chemical into your collected rainwater. The system is highly configurable and dosing amounts are freely adjustable.
This is not a complete system. The Econ FP pump is a proportional flow pump that injects chemical into the rainwater based upon the amount of water flowing through it. Therefore, an additional control component that can monitor the flow of water is required for the system to be operational. In order to create a complete system you can add either a pulse water meter
or a flow switch. Either of these devices will monitor the flow of water and send a signal to the pump to add a dose of chemical based on the amount of water flowing through it.
