Company record

Van der Graaf Inc. designs and manufactures motorized pulleys that meet the rigorous requirements of the bulk‑handling sector worldwide. Its drum‑motor solution integrates the motor, gear train and all moving components inside a single drum, creating a compact, self‑contained conveyor drive. The units are offered in mild‑steel or stainless‑steel construction, span diameters from 100 mm to 800 mm, and cover a power range of 0.10 hp to 180 hp, making them suitable for diverse environments such as ship loading, mining operations, airport baggage systems, power‑generation facilities, and food‑processing plants. Key engineering attributes include cast‑iron internal parts, an oil‑filled lubrication bath that removes heat, hermetically sealed housings to prevent leaks, honed and ground gear surfaces, and vacuum‑pressure impregnation. Customers can select lagging material from urethane, hot‑bond, ceramic, or tungsten‑carbide options to match specific service demands.
