Aquatec's tank pressure switch is available to turn off the booster pump when the tank is full. It should be mounted in-line, as close to the tank as possible. The normally closed switch is pre-set at the factory for shutoff pressure of 40PSI. It comes with 2 John Guest half cartridges, for 1/4" tubing.
The switch also comes with a wiring harness for interconnection with your CDP6800 or CDP8800 pump and acessories.
Note: The pressure switch can be field modified to operate as a normally open switch by changing the wire terminal connector from the NC to the NO switch spade contact.
