Afla Laval decanters provide exceptional performance when separating solids from 1 to 2 liquid phases in one single continuous process. The Alfa Laval decanter centrifuges are to use in a range of duties including beverage and food processing, pharmaceutical production, and biofuels. The Alfa Laval centifuge is driven by it's own gearbox, and is factory equipped with lip seals. Those lip seals would hold up for about 6 months, then the gearbox would begin leaking lubrication. A customer of John Crane Sweden needed to find a better solution, in both run time, and costs savings.
The customer was introduced to Isomag bearing isolators through a John Crane engineer. The gearboxes are installed horizontally in the plant, and the housing is filled to the centerline of the shaft in an ISO 220 gear oil. Isomag bearing isolators are unique in that they are both a positive seal but also do not damage the shafts on the host equipment. The customer went from a MTBF of 6 months to more than 10 years without a hitch. Saving that hundreds of thousands in cost savings for a relatively small investment.
