• HS-2172 Centrifuge

    BRANDT™ centrifuges are typically configured to meet the specifications demanded by the application. 

    The HS-2172L centrifuge is fed from the solids end of the conveyor. Mud is introduced into the feed chamber of the HS-2172L through a feed tube and, with the aid of a concave accelerator, exits through twelve (12) nozzles into the bowl.

     

    Description

    MAXIMIZING PERFORMANCE, EFFICIENCY AND OPERATIONAL SIMPLICITY WITH THE MOST INNOVATIVE DECANTING CENTRIFUGE AVAILABLE

    Centrifuges are used to process unweighted and weighted, water-based and oil-based drilling fluids (muds). The HS-2172L centrifuge uses high G-forces to separate fine solids from liquid.

    The HS-2172L centrifuge is fed from the solids end of the conveyor. Mud is introduced into the feed chamber of the HS-2172L through a feed tube and, with the aid of a concave accelerator, exits through twelve (12) nozzles into the bowl.

    The HS-2172L is equipped with variable frequency drive (VFD) control, which provides a controlled application of motor drive power to the centrifuge components (bowl, conveyor and feed pump). Customized hardware and software packages can be designed to meet specific installation and operational requirements. With a processing capacity of up to 550 gal/min (2082 L/min), the HS-2172 series centrifuge is able to quickly process high volumes of mud while allowing prescribed mud weights and separation efficiencies to be maintained. This enables the HS-2172 series centrifuge to produce fine cut points at higher flow rates, making it ideal for high-flow applications and critical-conditions solids control.
