The VMK-Series models are Viber® Electric Power Units, which connect to standard flexible shafts and vibrating heads for use in concrete construction.  VMK Series power units utilize Universal-style 60Hz motors in 120V or 240V models.  These powerful motors are capable of producing extremely high revolutions per minute (rpm) and rely on the resistance from the vibrating head to reduce the vibration frequency to the desired level.  VMK Concrete Vibrators are available in three electric motor sizes to be compatible with a wide range of Vibrating Heads.

• VMK-1500 Models feature 120 Volt/10 Amp or 240 Volt/5 Amp motors and are compatible with small to medium Head sizes.
• VMK-2750 Models feature 120 Volt/15 Amp or 240 Volt/7.5 Amp motors and are compatible with medium to large Head sizes.
• VMK-3500 Models feature 120 Volt/20 Amp or 240 Volt/10 Amp motors and are compatible with medium to the largest Head sizes.
