GNMS series slurry separation plants have been GN Solids Control’s best seller products for non-oil and gas industries, for HDD, TBM, pipe jacking, water well drilling and other drillings. All GNMS series separation plants are divided into 2 groups: self-contained ones and the compact ones. Compact designs are called the D edition, which are quite popular because of the compact design and wide applications.

Recently GN Solids Control has manufactured several sets of such compact systems to an Asian client. This system is called GNMS-1500D, with a treating capacity up to 1500GPM. This machine contains following components:

1. Two sets of desanding cyclones, each with a 14 inch diameter. The desanding cyclones are used for 2nd step treatment of the slurry, for removing the sand particles larger than 40 microns.

2. One set of double deck shale shaker. This shale shaker is a quite big shaker with double layer deck with composite material shaker screens. The lower deck screens are more coarse than upper deck screens, and even more coarse than the desanding cyclones’cutting point. Normally, the lower deck screens are API 10 or API 20.

3. Feeding pump for the desanding cyclones is a centrifugal pump with a 75kw motor. Centrifugal pumps are widely used as desanding feeding pumps. GN is also good at making centrifugal pumps by using hard alloy as pump casing and impeller.

4. All 3 equipment mentioned above are based on one catch tank, the drilling fluids falls from shaker lower deck to the catch tank, then pumped to the cyclones for second step separation. After that the solids discharged from cyclones falls again to the catch tank via the upper deck screens.

In this way, the drilling fluids become clearer by cycling.
Besides GNMS-1500D, there are GNMS-1000D, GNMS-500D and GNMS-200D available.
