GEA Westfalia Separator OTC 20-01-037

Machine Application

The GEA Westfalia OTC 20 centrifuge is equipped with a solid-wall bowl for clarification of liquids or purification of liquid mixtures with simultaneous removal of solids. The product enters the rotating bowl through the product feed and is separated in the disc stack. The separated and purified light and heavy liquid phases flow outwards over the separating disc and are discharged under pressure by the centripetal pumps. The separated solids collect in the solids holding space and must be removed by hand.

Separator Design

The separator of enclosed design is equipped with an oil level sight glass. The hood is hinged. The machine is driven by a 3-phase AC motor. Power is transferred to the bowl spindle via a flat belt. All bearings are splash-lubricated from a central oil bath.
