GN produced drilling fluids decanter centrifuge including high speed decanter centrifuge, low speed decanter centrifuge, middle speed decanter centrifuge and variable speed decanter centrifuge. For high gravity drilling mud, we recommend middle speed centrifuge. For low gravity drilling mud, we recommend high speed decanter centrifuge GNLW363G with 3200rpm rotary speed. If you bought our variable speed decanter centrifuge GNLW363VFD, you can adjust the speed by the PLC control panel. If you bought our rated speed decanter centrifuge, we can provide 3 sets of extra pulleys to change the high speed to middle speed or low speed decanter centrifuge.

For better performance of GN decanter centrifuge, you should pay attention to the following points:

1 Lubrication according to the lubrication chart we recommend, especially for the 2 bearing blocks, gear box, hydro-coupling.

2 Cleaning and flushing: the centrifuge bowl inside and outside should be flushing after every time start, to avoid the solids accumulated around the solids discharge port.

3 Proper feeding capacity to ensure there will not be too much solids accumulation.

4 Use proper speed for different drilling fluids, change the speed by change pulleys or by manually adjustment in the PLC control panel

5 Replace the spare parts in time once any wear parts are damaged

6 separate the big solids by shaker screens or hydrocyclones before feeding them to the decanter centrifuge
