    CUSTOMIZABLE SOLIDS CONTROL WITH COST-EFFECTIVE, SIMPLE DESIGN AND DURABLE PERFORMANCE

    Hydrocyclones are simple mechanical devices, without moving parts, designed to speed up the settling process of solids. Drilling fluid containing solids is fed into the body of the hydrocyclone, where the centrifugal force induced by the flow causes heavier solids to separate from the lighter solids. The heaviest solids are discharged out the bottom (underflow) of the hydrocyclone and the lightest solids exit the top (overflow). The separation of solids is dependent upon feed particle size, fluid viscosity, fluid feed pressure (as a function of fluid density) and hydrocyclone size. NOV offersthree (3) models of hydrocyclones:

    • Desanders (10-inch cones)

    • Desanders (12-inch cones)

    • Desilters (4-inch cones)

    Contact your NOV sales representative for more information, as well as to obtain proper sizing.
