VDG (Van der Graaf)
Shelby Township, MI 48315
Operating in USA and Canada for 35 years, VDG (Van der Graaf) is the premier manufacturer of drum motors for belt conveyors, providing innovative drive solutions to industry challenges in the food, processing, and material handling industries.
A one component conveyor drive with all moving components enclosed inside the drum.
Designing and manufacturing drum motors for belt conveyor applications for over 35 years, VDG (Van der Graaf) has adhered to a simple principle: providing reliable solutions to the material handling and food processing industries, through innovation, research & development, and precision manufacturing.
The innovative, streamlined VDG Drum Motor has all drive components including motor and gearbox enclosed inside the drum for a safer, more efficient, and space optimized belt conveyor drive solution. Reducing energy expenses by 30% per drive, all components of the VDG Drum Motor are designed for 80,000 hours of continuous operation before maintenance, minimizing downtime, reducing maintenance costs, and increasing production.
VDG Drum Motors with new patented IronGrip™ lagging extends the lifetime of the lagging, the belt, and the overall conveyor system by eliminating lagging delamination and reducing wear on the belt and lagging. Composed of steel bar reinforcements welded onto the drive shell with sectional rubber lagging inserts, this patented design transfers load forces more efficiently than standard rubber lagging, extending the lifespan of the overall conveyor system. With up to 40% more traction than standard SBR rubber lagging, the IronGrip™ allows for less pre-tensioning while providing higher belt-pull.
In food processing plants where sanitation is paramount, the all-316 stainless steel SSV Sanitary Series drum motor features an IP69K sealing system that withstands up to 3,000 psi washdown pressure. The USDA approved SSV drum motor has the belt profile machined directly onto the drum to drive modular, wire belt, and monolithic thermoplastic conveyor belts without the use of sprockets. This sprocketless design eliminates foreign material contamination and areas prone to food by-product buildup and bacterial harborage, cutting washdown time and water consumption by 50%, and further minimizing downtime.
The latest IntelliDrive™ drum motor with i-Controller features an integrated VFD (Variable Frequency Drive), which provides conveyor drive data feedback and controls belt speed either remotely or directly at the drum motor. The IntelliDrive™ simplifies belt speed selection without the loss of torque or belt-pull, substantially increasing the efficiency and the life of the electric motor.
All VDG Drum Motors are engineered and manufactured in-house in USA and Canada, using cutting-edge production technology and automation, ensuring quality control, fast delivery, and after sales service. With global representation and service centers throughout the USA, VDG offers customized solutions to a wide customer base. VDG drum motors are available from 0.25hp to 500hp, with a wide range of belt speeds and lagging options to suit all types of material handling and processing systems.
