At Van der Graaf, we are committed to quality and efficiency, and this is reflected in our Extreme Duty drum motors designed specifically for harsh and abrasive environmental conditions of the mining and aggregate handling industry.
Extreme Duty drum motors, available from 50hp to 250hp, 20-32 inch diameter as standard, provides the mechanical efficiency and longevity for the high demand and harsh environment of aggregate and mining applications. The new mechanical seals are designed to protect all internal components from fine to course dust. The Extreme Duty drum motor is designed to provide years of continuous service with no downtime.
No scheduled maintenance is required other than an oil change every 50,000 hours of operation for most applications since all components of the drum motor is enclosed within the drum in an oil bath.
