GN Solids Control takes pride in its position as a professional decanter centrifuge manufacturer. We uphold stringent standards for the selection of raw materials, opting for high-quality centrifugal casting or forging stainless steel materials. When it comes to wear-resistant components, we employ hard alloy protection, ensuring extended durability and peak performance. Our commitment to quality and durability is unwavering, reflecting our dedication to customer satisfaction.

GN has forged a fruitful collaboration with Viscotherm, a world-leading hydraulic system brand. This partnership has resulted in the development of the Full Hydraulic Drive Centrifuge, which meets the highest industry standards. The ROTODIFF hydraulic motor, a high-torque radial piston motor, controls the differential speed between the bowl and scroll, ensuring precise and efficient separation.

It’s worth noting that our centrifuges come equipped with a manual speed-adjustable feed pump. All components of these feed pumps are sourced from renowned German brands and assembled in China, enhancing their durability and reliability. Thanks to our partnership with NETZSCH, we can offer these pumps at a more cost-effective price compared to the official site.

Hydraulic Centrifuge and Screw Pump: A Match Made for Wastewater Treatment.

Hydraulic centrifuges and screw pumps are two types of equipment that are often used together in industrial applications. The hydraulic centrifuge is used to separate solids from liquids, while the screw pump is used as the feeding pump for the centrifuge.

GN Solids Control is a leading manufacturer of decanters centrifuges. We have partnered with Viscotherm and ROTODIFF®, leading brands of centrifuge hydraulic driving systems from Switzerland, to develop the Full Hydraulic Drive (FHD) Centrifuge. This centrifuge meets the highest standards and is designed for international clients. The FHD Centrifuge uses a hydraulic bowl and scroll drive system that is powered by a hydraulic pump unit. This system drives both the hydraulic motor ROTODIFF and the bowl of the centrifuge. The two hydraulic oil circuits allow for independent, stepless, and large-range speed regulation for the bowl and conveying. The FHD Centrifuge has several advantages. It can be used in high-temperature ambients, is designed for heavy mud, and has a flexible bowl and differential speed. The compact one-skid design makes it easy to rig up.

A screw pump is a progressive cavity pump that uses a rotating rotor with a series of helical blades to move fluids. The blades create a series of chambers that trap the fluid and move it along the pump. The pump is gentle on the fluid, so it does not shear or agitate it. It can handle high-viscosity fluids and hard-suspended particles for a mud system, and a good feeding pump for centrifuges. It is easy to maintain, better pumping than a centrifugal pump, and the only worn parts are the rotor and stator.

The combination of the centrifuge and the screw pump could be mounted with a skid:
