Savings Compared to ConventionalMENU

Drum Motor FeaturesLubricant/Cooling An oil bath ensures that heat is transferred through the lubricant, onto the drum, to dissipate on the belt.MENU

Drum Motor FeaturesHermetic Sealing Van der Graaf manufacturers and engineers seals that are specific to the industry to provide a leak proof environment.MENU

Drum Motor FeaturesHoned and Ground Gears Using alloy steel, gears are machined and honed to AGMA/DIN6 standards and exceed OSHA low-noise requirements.MENU

Electric MotorVan der Graaf designs Drum Motors specific to each environment. The drum motor can be supplied in all standard voltage or any nonstandard voltage and frequency for three phase or single phase applications.

Vacuum Pressure Impregnation(VPI)MENU

LaggingUrethane Utilizes a unique ribbon flow method of coating cylinders with high durometer urethane.Hot Bond A vulcanization process that adheres colandered rubber to the exterior of a drum motor shell. The result is a seamless, durable, and tear resistant finish.Ceramic Rubber lagging with ceramic tiles embedded improves traction and abrasion resistance. Typically used for larger HP drives that work in harsher environments.MENU

Tungsten Carbide InfusionAs an alternative to conventional lagging, Van der Graaf has developed a traction coating layer of infused tungsten particles embedded into the surface of the drum using a thermo spray system.MENU

Range of Drum MotorsAvailable in both standard material and stainless steel, Van der Graaf Drum Motors can be used in all applications in order to enhance any bulk or material handling system.
