GN Solids Control delivered one batch of hydraulic decanter centrifuges and vacuum pumps to Africa, where all GN equipment will be used in an oil sludge treating plant. 
GN Solids Control has been building decanter centrifuges for many years, classified by the decanter centrifuge driven unit, GN Solids Control is able to provide fully hydraulic drive centrifuge and electrical drive centrifuge. As for this African client, GN Solids Control shipped 2 sets of fully hydraulic decanter centrifuges. 

GN Solids Control works with Viscotherm and Rotodiff from Switzerland to develop the fully hydraulic drive 14 inch bowl centrifuge GNLW363-FHD. Centrifuge rotating bowl as well as the screw propeller are both using Rotodiff hydraulic motor. 
By using hydraulic drive system, GN Solids Control centrifuge can work in high temperature with flexible rating speed when treat heavy PPG drill mud. GN professional engineers deign this fully hydraulic centrifuge in a compact lifting structure. 

With wear resistant rotating bowl of duplex stainless steel 2304 or 2205, SS304 screw propeller, GN decanter centrifuge can work in most harsh environment. Furthermore, GN Solids Control centrifuge is using tungsten carbide tiles to cover the edge of screw propeller. And the main two bearings are genuine SKF brand.  
Besides the decanter centrifuge, GN Solids Control also provides 2 sets vacuum pumps includes one 40 m3/h and one 20 m3/h. GN vacuum pump is especially designed to move high solids content sludge, in fact as long as the material is moveable, GN vacuum pump can have excellent working performance. 

GN Vacuum Pump is driven by air which demands an Air Compressor. All the components on the vacuum pump are either mechanical parts or air parts without any electrical parts, so GN vacuum pump can be used in any hazardous environment. 
GN Solids Control also build other solids and liquid separation and conveying equipment, please connect with GN sales reps for more info.
