The All New Dura-Drive SPM Synchronous Permanent Magnet Pulley

Sparks Belting recently launched the all new synchronous permanent magnet pulley, the Dura Drive SPM. It is a compact and robust All-in-One drive component that can be used with all types of belt conveyor systems, including plastic modular belt systems. The Dura Drive SPM is highly energy efficient, exceeding IE4 efficiency limits, and is designed to meet IE5 requirements. The Dura Drive SPM delivers high torque and belt pull that remains constant over a wide range of operating speeds.
