Float Switches

The standard level control design for submersible pump installations. As the float is lifted by the medium a ball inside activates a microswitch that then activates the pumps. Also available on some pumps as a built in option where a single pump is being used. On twin pump systems a minimum of three individual switches are recommended and a fourth should be considered to act as a high level alarm. For this design the usable capacity of the pump chamber should be no less than 1,000 mm in depth.
