Dura-Drive
Plus
The Dura-Drive Plus drum motor from Sparks Mol is a small yet powerful one-piece pulley system that’s guaranteed to power your belt conveyor for years without breakdown.
Compact, Safe &
Clean Operation
Unlike bulky conventional drive systems that fit externally on a conveyor, Dura-Drive Plus drum motor is actually part of the conveyor and much more compact. That means you can fit more conveyor into less floor or overhead space. Also, all moving parts are enclosed in the steel drum motor shell eliminating hazardous moving parts and pinch points along with the potential for electric shock from water on motors. Dura-Drive Plus is cleaner because there is no external grease or oil from chains, bearings, or couplings. As a result, you improve employee safety and more readily comply with OSHA standards.
What is a Drum Motor?
A drum motor is a motorized pulley in which the body rotates around a stationary shaft. The rotating outer “drum” becomes the traction surface which powers the conveyor belt. Electric power leads pass through the stationary shaft to motor terminals inside the pulley housing.
The entire internal mechanism, including the motor, gears, and bearings, is completely sealed and protected by the outer metal drum. The oil inside the drum continuously lubricates bearings and gears and removes heat from motor windings.
Conventional Belt Drive
Sparks offers the Dura-Drive Plus belt drive, which has a completely sealed internal mechanism that is safer and cleaner than a conventional belt drive. The conventional belt drive has a lot of external moving parts that could catch on different things and it is more prone to damage from surrounding elements.

Electric Motor
All Sparks Mol drum motors are tested to UL 1004 – 1:2012 standards with Class F insulation standard (Class H insulation available upon request). The motor is an asynchronous squirrel cage induction type. Class F motors are suitable for most applications with ambient temperatures of +100°F to -10°F. They have inverter duty motors and can therefore have a step-less speed control in combination with static frequency converters in the range from 30 to 70 Hz.
Protection Class
Protected to IP69k, in accordance with VDE 0470, and suitable for applications requiring high-pressure washdowns.
End Caps
Our drum motors come with press-fit or bolt-on end caps for easier servicing. The housings are manufactured from seawater-resistant aluminum or iron; 304 stainless steel is also available.
Simple Design
Because Dura-Drive Plus is a one-piece drum motor and not 10 or more separate components like a conventional drive, it can be easily specified into new systems and dramatically reduce design time. Changeover takes less than an hour per drive. Dura-Drive Plus drum motors can also be supplied with optional mounting brackets.
Cost Effective
Priced competitively with conventional systems and more energy efficient. A conventional system normally transfers only 60-75% of its mechanical efficiency (horsepower) to the belt. Dura-Drive Plus transfers 95% of its capacity to the belt–
a 20-35% increase. These savings can translate into a reduction of hundreds of dollars in energy costs per drive, per year. When you add in the reduced maintenance costs it’s easy to see how Sparks Mol motorized drum motors can quickly pay for themselves in a matter of months.
Quiet Operation
Dura-Drive Plus motorized pulley operates at a very quiet 57-64 decibels, compared to 76-80 decibels for a typical conventional drive. A quieter operation can help you meet OSHA noise regulations, eliminate the need for costly ear protective devices for workers, and improve your overall work environment.
