GN Separation is proud to announce the successful shipment of one of our large model dewatering decanter centrifuges, the GNLW654-VFD, to an overseas client for industrial sludge treatment. This delivery highlights the increasing global demand for GN's high-performance separation equipment and showcases our technical expertise in providing efficient, reliable, and energy-saving solid-liquid separation solutions.

 

Powerful Performance for Demanding Applications

The GNLW654-VFD is part of GN’s T Series dewatering decanter centrifuges, engineered with an optimized beach angle of 8.5 degrees to enhance dewatering efficiency and discharge drier solids. This model is specifically designed to handle materials with large particle size, high solid-liquid density difference, high concentration, and low viscosity, making it ideal for municipal and industrial wastewater, oily sludge, drilling mud, chemical wastewater, sand washing water, and more.

Key Features of the GNLW654-VFD

• Large Bowl Design: With a 650 mm (25.6 inch) bowl diameter and 2730 mm (107.5 inch) length, the GNLW654 offers high throughput capacity and effective sludge dewatering performance.

• High G-Force: Operating at a max speed of 2873 RPM, this model generates a G-force up to 3000G, facilitating rapid and thorough separation.

• Premium Materials: The bowl and screw are made of duplex stainless steel (SUS2304 or SUS2205) through centrifugal casting, offering superior corrosion and wear resistance compared to conventional SS304 or SS316.

• Energy-Efficient & Low Noise: The design includes a deep liquid pool, optimized cone angle, and anti-turbulence structures, contributing to better clarity, reduced energy consumption, and quieter operation.

• Wear Protection: The solids discharge ports and screw flights are protected with tungsten carbide sleeves and replaceable wear-resistant tiles, ensuring long service life even under harsh working conditions.

• Smart Control: Equipped with a VFD+PLC+HMI control panel, the centrifuge allows real-time monitoring of vibration, temperature, torque, and lubrication status. Emergency protocols such as automatic plugging and shutdown procedures are in place for safe operation.

• Space-Saving Layout: Both motors are installed at one end of the unit for compact design and easier maintenance access.

Reliable Dewatering for a Wide Range of Materials

GN’s T Series decanter centrifuges are versatile and widely applied in industries such as:

• Municipal wastewater and sludge treatment

• Oilfield drilling fluids and oily sludge recovery

• Sand and mineral washing

• Steel-making and precision casting wastewater

• River and lake dredging

• Chemical, pharmaceutical, and food industry wastewater

• Salt and kaolin recovery

• Biomass, aquaculture, and more

For materials with fine particles, GN also recommends using flocculants to enhance solid aggregation before centrifugation, enabling more efficient separation.

Customized & Turnkey Solutions

In addition to standalone centrifuges, GN Separation offers complete dewatering process solutions by integrating our wide range of separation and conveying equipment. We support system customization based on project-specific requirements and deliver comprehensive support from equipment selection to on-site service.
