The MVSI-ACC series, deriving directly from the MVSI series, is characterised by the motor shaft projecting from one side or from both sides, allowing in-line coupling, using a coupling, between two or even more equal vibrators. The MVSI-ACC series is very useful for manufacturers of large screens and vibrating machines, or for plants that require very high centrifugal force values. With two vibrators of the MVSI-ACC series coupled in line, it is possible to arrive at a centrifugal force of 134000 lbs (600kN). Italvibrasusa technical staff can help the user in the choice of the coupling as well as in the application of the vibrators.
