For this project, the client required a pumping solution capable of operating under harsh drilling conditions, handling abrasive fluids, and ensuring precise flow performance for downstream solids control equipment. GN’s engineering team selected the GNSB Series centrifugal pump as the core transfer unit. Built with a hardened, wear-resistant pump casing, high chrome alloy components, and a robust mechanical seal, the GNSB pump is well suited for continuous operation in challenging drilling mud environments.

One of the advantages emphasized by the European client is GN’s fully interchangeable design. The GNSB pump shares common dimensions with major global pump models, enabling convenient replacement of parts and seamless integration into existing mud systems. This compatibility minimizes spare parts inventory and reduces long-term maintenance cost — a non-negotiable requirement for many European drilling operators working under strict cost-efficiency guidelines.

Complementing the transfer pump, GN also supplied the GNJQB Series shear pump, which plays a critical role in drilling mud preparation. The shear pump is engineered to break down bentonite and polymers rapidly, significantly improving hydration and ensuring uniform mud properties. Unlike standard centrifugal pumps, the GN shear pump produces a powerful shearing effect that enhances fluid structure, stabilizes gel strength, and shortens mud mixing time.
For drilling contractors, optimized mud mixing directly translates into better wellbore stability, reduced chemical usage, and more consistent drilling performance. With environmental regulations tightening across Europe, the ability to reduce additives without compromising mud performance is a major operational advantage.

Before shipment, all equipment underwent GN’s comprehensive quality inspection, including:

As hydrovac excavation continues to expand across global markets, efficient slurry management has become a critical operational requirement. Hydrovac trucks generate large volumes of water-soil mixtures that must be processed, dewatered, and disposed of in a cost-effective and environmentally compliant manner. To help contractors reduce disposal costs, recover reusable water, and minimize downtime, GN Solids Control has delivered its GNLW454GT Mud Dewatering Centrifuge, designed specifically for hydrovac slurry treatment applications.

The GNLW454GT is a high-capacity, 18-inch bowl decanter centrifuge, engineered to handle fine solids separation while maintaining continuous and stable operation. Hydrovac waste typically consists of fine clay, silt, sand, and suspended solids with varying densities. These characteristics require a centrifuge with strong torque output, precise control of differential speed, and high G-force to achieve effective liquid-solids separation. The 454GT meets these challenges through its enhanced torque gearbox, wear-resistant bowl design, and optimized scroll geometry.

One of the major advantages of using the GNLW454GT in hydrovac slurry treatment is its ability to significantly reduce the volume of liquid waste, producing a drier solids discharge. The dryer the solids, the lower the disposal cost—and for many hydrovac contractors, disposal fees represent the largest operating expense. With the GN centrifuge, customers have reported substantial reductions in the number of truckloads sent to disposal sites, improving both operational efficiency and profitability.
In addition to solids reduction, the centrifuge produces clearer effluent water, which can be reused on site for hydrovac operations or discharged according to local environmental regulations. This not only minimizes fresh water consumption but also supports more sustainable jobsite practices.

The GNLW454GT is built with robust, industry-proven materials, including tungsten carbide wear protection on the scroll, tiles along the bowl inner surface, and an abrasion-resistant feeding system. All components are designed to withstand the highly erosive nature of hydrovac slurry, ensuring long service life and reduced maintenance frequency. The machine is available with either VFD control or fixed-speed operation, with the VFD package allowing operators to adjust bowl speed, differential speed, and feed rate in real time to achieve optimal performance under changing conditions.

For mobile jobsite requirements, GN also provides skid-mounted or containerized system options, integrating pumps, polymer dosing units, and control panels into a compact processing unit. This allows the GNLW454GT centrifuge to be deployed at transfer stations, hydrovac dumping facilities, recycling centers, or directly at project sites.
