Transcript of Van Der Graaf Presentation

  • Manufacturer of Heavy Duty High Precision Drum Motors

  • Modern manufacturing facilities in the US, Canada, and Holland utilizing the latest technology and expertise.

    Company ProfileMENU

  • What Is a Drum MotorThe Van der Graaf Drum Motor is a one componentconveyor drive in which the motor, gear drive, and allmoving parts are enclosed inside the drum.MENU

  • Design BenefitsMENU The Drum Motor Design:

    IncreasesVersatilitySpace utilizationDurabilityProductionSafety

    ReducesMaintenance DowntimeNoiseEnergy & Operating Costs

  • Drum Motor AssemblyMENU

  • Comparison to Conventional MENU The Drum Motor offers a much less complex and more efficient way to power your belt conveyor.

  • Comparison VideoMENU

  • 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.

    Varieties include:

    Diameter Sizes (4 36 inches)Various Belt Speeds (3 ft/min 1800 ft/min)Horsepower (0.10 250)


  • Sanitary Series Drum Motors(SSV)

    Ideal for the food industry Essential to conveyors requiring sanitary wash downSSV Labyrinth Sealing SystemPrevents contaminants from penetrating the sealing integrity of the unit.SSV drum motors are capable of handling 2000psi wash down pressure.MENU

  • Cross DriveThis design has all the benefits of the Drum Motor combined with the flexibility of an external electric motor for quick and easy installation.MENU

  • The Extreme Duty Mining Series Drum Motor is a robust unit for mining applications able to withstand heavy shock loads.Engineered for the harshest environments.Diameter: 20 36 inches

    Horsepower: 50 250 Extreme Duty MENU

  • IndustriesThe Van der Graaf Drum Motor is built to meet the requirements of any application. Our industries include:

    Airport Baggage HandlingPostal/ParcelFood Mining & Aggregate


  • ROI SummaryReduced maintenance and downtime only an oil change every 50,000 hoursEnhanced space utilization fit more lines into less floor or overhead spaceWith 96% mechanical efficiency, power savings of over 30% are possibleAGMA/DIN 6 gear standards reduce operating noiseEnhanced operator safety by eliminating external moving parts


  • PrincipleVan der Graaf adheres to one principle:

    Design a superior product to meetcustomer needs in a changing marketplace

    As a result VDG has been the premiere supplier of conveyor belt drives for over 60 years worldwide and continues to answer the demands of the material handling industry.

    Thank You
