Decanter Centrifuge

GNLW Decanter Centrifuge provides high-speed, variable-speed, big bowl and big volume centrifuges designed specifically to process drilling fluids/mud and drilling wastes to meet the highest environmental standards. High fluid recovery rates and efficient solids control are crucial to any drilling operations. By using GN decanter centrifuges, it will help drilling contractors dramatically reduce total drilling fluids cost and leave much less drilling waste for disposal.

GN Decanter Centrifuges are mainly utilized for the following devisions:

decanter centrifuge

Oilfield Decanter Centrifuges for oil & gas well drilling operations are designed with solid bowl diameters of 14 inch to 22 inch and bowl length of 50 inch to 71 inch. Most centrifuges are available in Fixed Speed (G/S marking) and Variable Speed (VFD marking).

GNLW363 are cost-effective, most durable, high speed centrifuge for drilling mud solids control.
GNLW553 are big bowl, big volume, high efficiency decanter centrifuge for drilling waste management.

Mining & Diamond Drilling Operations Mini Centrifuge , we specially designed small capacity, small footprint centrifuge for very fine solids separation.
