In collaboration with Van Beek and CinchSeal, the new NVB heavy duty seal was developed for screw conveyors and mixers in the food, chemical, bulk and process industries.
The NVB Seal has rotating internals with a wide elastomer sealing off the drive shaft, protecting it against wear and driving two heavy duty Rotor Cups. These sealing discs are extremely robust, wear-resistant and form a large sealing surface against the housing of stainless steel and aluminum. The housing creates an internal compression that is supported by an air purge with which the NVB Seal is adjusted to the operational pressure in the application.
All NVB Seals allow up to 6 mm radial movement and up to 2° of shaft misalignment. Due to the bolt hole pattern according to the CEMA norm, standard flange bearings can be mounted directly against the NVB Seal.
The NVB Seal is an ideal and proven sealing solution for transporting and processing sugar, syrup, starch, soy, inulin, sodium carbonate, aluminum trihydrate, sand-lime brick and rubber. The maintenance and wear-free working method saves costs from day one and the elimination of product leaks plus 30% less energy consumption guarantee a positive return!
