The MVSI-ACC Series utilizes the continuous-duty MVSI platform design including IEC standards, but also includes the Extended Shaft option for shaft projections on one or both ends. This Series enables the coupling of an additional Vibrator(s) (same model & size) to generate the increased centrifugal force required for very large Vibratory Equipment, or large Bunkers or Silos. Our Technical Support Staff can assist with sizing Vibrators and selecting the coupling when connecting additional vibrators. These Vibrators are available: 3Ph Power; in 3600-RPM, 1800-RPM, 1200-RPM or 900-RPM @ 60-Hz / 3000-RPM, 1500-RPM, 1000-RPM or 750-RPM @ 50-Hz; Centrifugal Forge Range: 66 to 67,000 lbf.
