A key component of the BOS product offering is our line of variable speed centrifuges which provide optimum solids removal from slurry waste, drilled solids, barite recovery and cuttings drying. BOS offers three styles of decanting centrifuges, the BOS 20, BOS 40 and BOS 60. Depending on the arrangement of the system, process rates range from 265 gpm (1000 lpm) to 1410 gpm (5350 lpm), with a solids rate removal of 5.5 Ton (5 Tonne) - 34 Ton (30.8 Tonne).

All of our centrifuges come complete with a variable frequency drive panel controlling the main drive motor, back drive motor, gearbox, overload protection, vibration switch and feed pump.
