Compact!

• Hermetically Sealed
• Aesthetic design
• Space saving compact design
• Light weight
• Safer than conventional drives

Hermetically Sealed IP67

• RULMECA
• Motorized Pulleys - the perfect drive unit for
  corrosive chemicals and abrasive bulk materials
• Copper steel
• Coal
• Limestone
• Potash
• etc.

Easy to Maintain

• RULMECA
• Motorized Pulleys Low Maintenance Requirements
  (change oil every 10,000 operating hours)
• Remove magnetic oil plugs
• Wipe off sludge
• Drain oil
• Refill

10
High Efficiency

• The pulley is driven directly by the internal
  gearbox, giving the Motorized Pulley an
  efficiency of

95
Therefore, less energy is required. This makes
Rulmeca Motorized Pulleys to one of the most
economical conveyor drives.
11
Extra Thermal Protection

• All RULMECA
• Motorized Pulleys have 3 built-in thermal
  protection switches
• Connect to normally closed
  control circuit
• Designed to provide back up to plant
  current overload protection
