GN Solids Control just shipped 4 packages of fully hydraulic drive decanter centrifuges to Middle East. As one the world famous decanter centrifuge manufactures, GN Solids Control has been manufacturing different sizes of decanter centrifuges for many years.

Now GN Solids Control is able to provide electrical driven and hydraulic driven decanter centrifuges, among them GN 14 inch and GN 18 inch bowl decanter centrifuges are largely equipment with hydraulic driven unit.

Due to the oil price going down and the double effect of COVID-19, the global oil and gas industry is very slow this year. But GN Solids Control succeeded to provide more solids control and waste management systems when customers try to find the most cost-effective equipment. Until now, GN Solids Control has been provided solids control equipment as well as drilling waste management systems to over 70 countries and regions. Word of mouth highly reputation bring more and more orders to GN Solids Control. GN Solids Control has provided hundreds of in Middle East. Usually, orders from Middle East are large orders with strict and high technical demands. With these years fast development, GN Solids Control is always able to provide the decanter centrifuges beyond customers’ expectation as GN wants to take the extra step.

The hydraulic bowl and scroll drive system drives both the conveyor and bowl of a decanter centrifuge from hydraulic pump unit by two hydraulic oil circuits.

The advantage of the full hydraulic drive centrifuge is for use in high temperature ambient for heavy mud with flexible bowl and differential speed. The compact one skid design makes it easier for rig up.

Bowl Size 360x1270mm
Bowl Speed 0-3400RPM (2328G)
Differential Speed 0-70RPM
Motor Power 45 KW
Driving System Switzerland Hydraulic Drive
Max Capacity 200GPM(45m3/h)
Max Torque 4163 N.M
Dimension(mm) 3000x2400x1860mm
Weight (KG) 3400KG

The full hydraulic system consists of A the Hydraulic Pump Unit, B the Bowl drive hydraulic motor, and C the Scroll drive.

The hydraulic pump unit A feeds hydraulic oil to the scroll drive C and the bowl drive B by means of two separate and individually independent operating circuits

An electric motor A1 drives the combined pumps A2 and A3. Each operating circuit is equipped with its own hydraulic pump and its own controls. The pump unit contains all setting devices and safety valves, as well as pressure gauges.

With this system, the bowl's rotational speed as well as the scroll's differential speed may be manually adjusted independently from one another, continuously and infinitely variable during the centrifuge’s operation.
