• Mission TurboShear™

    NOV Mission TurboShear™ reduces the cost of mixing polymers and clays while improving mud properties.

    Shearing the polymers eliminates fish eyes and prevents polymer chaining (long strings), which cannot pass through the shaker screens. The TurboShear pump is available as a belt-driven or diesel-driven package including a hopper, mud gun, and transfer line orifice plate. A complete system with skid, tanks, and piping are also available.
