Van der Graaf B.V. is manufacturer of drum motors.
Drum motors are used to drive conveyor belts.
The electric motor, gear drive and all moving parts of the drum motor are enclosed inside the drum. The motor and gears operate in a sealed oil bath enclosure, ensuring proper lubrication and cooling. The drum motor rotates a gear module which transmits power to the outer rotating drum. This concept ensures less maintenace and more reliability. The compact all-inclusive design makes engineering and installation easy.
