Small Diameter Hydrocyclone GTEK

2020-3-19  Description. GTEK Small Diameter Hydrocyclones are designed for very fine separations.In many applications Small Diameter Cyclones can be used in place of decanting centrifuges, providing the desired result at lower cost. The small hydrocyclones are limited on capacity so large numbers of these might have to be manifolded together in a close pack type vessels.
