RULMECAMotorized Pulleys - the perfect drive unit for corrosive chemicals and abrasive bulk materials: Copper & steel Coal Limestone Potash etc.
Hermetically Sealed – IP67

The pulley is driven directly by the internal gearbox, giving the Motorized Pulley an efficiency of:
Therefore, less energy is required. This makes Rulmeca Motorized Pulleys to one of the most economical conveyor drives.
95%
High Efficiency

Extra Thermal Protection All RULMECAMotorized Pulleys have 3 built-in thermal protection switches: Connect to normally closed control circuit
Designed to provide back up to plant current overload protection
