    I've got a 3 phase supply (380V), a vacuum pump+7hp. induction motor, a Float switch, and a 0.500kw. sintrifical pump, and a stop/start magnetic switch... The vacuum pump must run continuously but the sintrifical pump must run only when the float switch is activated. The whole system must be controlled from the stop/start switch. Please help

    How much electrical background do you have?

    Hey ET,
    Explain more, like what you are trying to accomplish, then these guys can help. Motors, makes, why. It all helps.

    This is pretty basic industrial electrical applications and manual start/stop and auto stop/start is performed via the motor starter equipment which also has to be sized correctly for the loads of the two motors.

    You really should find a qualified industrial electrician or engineer as there are lots of ways to do it wrong or dangerously and just a few ways to do it correctly. 3 phase AC industrial power is not a good place to start learning about electrical controls. ;)
