• HS-3400 Centrifuge

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

    The HS-3400 series centrifuge uses high G-forces to separate fine solids from liquid.

    Four models are available:
    • HS 3400 FS
    • HS 3400 FVS
    • HS 3400 VSD
    • HS 3400 VS

    Description

    FUSING HIGH EFFICIENCY AND COMPACT DESIGN FOR MAXIMUM PERFORMANCE AND EFFORTLESS OPERATION


    Centrifuges are used to process unweighted and weighted, water-based and oil-based drilling fluids (muds). The HS-3400 series centrifuge uses high G-forces to separate fine solids from liquid. Four models are available:
    • HS 3400 FS
    • HS 3400 FVS
    • HS 3400 VSD
    • HS 3400 VS
    The HS-3400 series centrifuge is fed from the solids end of the conveyor. Mud is introduced into the feed chamber through a feed tube and exits into the bowl via four (4) nozzles. The HS-3400 FS is able to exert up to 2,275 G’s on the mud, while the HS-3400 VSD, HS-3400 FVS, and the HS-3400 VS are able to exert up to 2,100 G’s.
    The HS-3400 FS is a fixed speed drive unit, whereas the HS-3400 FVS and HS-3400 VS are 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.
    The HS-3400 VSD is a hydraulically-driven unit with a variable speed bowl drive. The HS-3400 FVS is electrically-driven, with both the bowl drive and conveyor equipped as variable speed. The HS-3400 VSD and HS-3400 FVS centrifuges offer increased operational flexibility in situations where conditions vary.
    With a processing capacity up to 200 gal/min (757 L/min), the HS-3400 series centrifuge offers outstanding performance over a wide range of drilling applications and conditions. Contact your NOV sales representative for more information.

    Features/Benefits

    FEATURES 

    BENEFITS 

    Up to 200 gal/min (757 L/min) maximum processing capacity

    Ample capacity for utilization in a variety of drilling applications and conditions (water)

    52:1 ratio planetary gearbox

    Provides for a reduced motor size

    Feed from solids end

    Provides a short feed tube with less vibration

    Variable frequency drive (VFD) control (HS-3400 FVS)

    Permits easy adjustment of bowl, conveyor and feed pump speeds for varying process conditions and also provide torque overload protection

    Bowl and heads manufactured of stainless steel

    Provides corrosion resistance for long life, smooth operation and low maintenance

    Stainless steel case

    Offers high strength and corrosion resistance

    Entire scroll fitted with sintered tungsten carbide tiles

    Offers abrasion resistance for maximum operational life and low maintenance

    Flush connections

    Aids in cleaning excess material from inside the case

    Case gaskets

    Retains process materials within the case to prevent spills or leaks.

    Vibration switch shut-off mechanism (HS-3400 FS, HS-3400 FVS)

    Automatically disables operation in situations of high vibration

    Case baffle gasket

    Keeps separated streams apart

    Torque overload mechanism (HS-3400 FS, HS-3400 VSD)

    Shuts down both the centrifuge and feed pump in overload situations due to blockage

    Roller and ball bearings

    Offers long life and low maintenance

    Sturdy WF-beam skid

    Supplies a solid foundation for smooth operation

    Eight (8) tungsten carbide solids discharge nozzles

    Offers an abrasion-resistant exit of solids from the bowl to discharge. These nozzles are also cost effective during refurbishment as they can simply be replaced rather needing costly repairs.

    Four (4) epicentric orifices

    Allows for high discharge flow rate and easy adjustment of the pond depth

    Chute style discharge for solid and liquid ends

    Allows for high-capacity processing
