    Description

    NOV Mission Supreme Shear™ pump features tungsten carbide chips adhered to the face of the impeller to give a rough surface that assists in the degradation of solids. This feature creates a high-wear resistant surface and imparts a mechanical action of shearing polymers into the fluid stream. By controlling the impeller size and speed, the Supreme Shear pump can incorporate both liquid and mechanical shear techniques to reduce the size of solids. The most common use for this application is shearing drill cuttings and injecting them behind the intermediate casing.
