At GN Separation, our 3 Phase Decanter Centrifuge is built on over ten years of experience, designed specifically for solid-liquid-liquid separation. This high-performance machine operates continuously and smoothly, ensuring the efficiency and quality that industries rely on for 24/7 production. Here’s why GN’s 3 Phase Decanter Centrifuge is an industry leader:

Key Features and Design

Our centrifuge comprises a driving system, high-grade decanter bowl, screw conveyor, cover box, durable skid, and a VFD control panel. Every component is engineered for optimal performance and durability, with materials chosen to withstand high speeds and demanding operational conditions:

• Bowl Material: Made from SS2205 Duplex Stainless Steel, the bowl is highly resistant to wear and corrosion, ensuring long-term reliability.
• Solids Discharge Port: Reinforced with Tungsten Carbide inserts for prolonged wear resistance.
• Screw Conveyor Material: Also crafted from SS2205 Duplex Stainless Steel, with Tungsten Carbide tiles for extra wear protection, essential for high-solid content applications.
• Material Distribution Nozzle: Equipped with Tungsten Carbide inserts, reducing wear and extending the component’s lifespan.
• Bearings: High-quality bearings from SKF or Japan’s NSK ensure smooth operation and durability.

Enhanced Control for Optimal Separation

The GN 3 Phase Decanter Centrifuge features an adjustable impeller, allowing operators to modify the depth of the heavy liquid “pond” in real time. Adjustments to the impeller position allow for precise control of the separation line between the two liquid phases. This flexibility enables customization based on varying liquid densities and proportions, ensuring the best separation results across diverse applications.

Separation Process and Working Principle

Our 3 Phase Decanter Centrifuge operates on the principle of sedimentation. When the material enters the high-speed rotating drum, centrifugal force separates the components based on their densities. The solid particles, as the heaviest phase, move outward to form a solid layer, followed by the heavy liquid phase (like water) and finally the lighter liquid phase (like oil). Solids are discharged through a screw conveyor, while separated liquids exit through designated nozzles. This process delivers precise and efficient solid-liquid-liquid separation.

• Oil spill recovery and hazardous waste transfer

This pump is perfect for industries like oil and gas, mining, petrochemicals, agriculture, and more, where safe, efficient, and high-performance material handling is required.

Working Principle

The GN Solids Vacuum Pump operates by utilizing compressed air. When compressed air enters the pump, it creates a high vacuum in the tank, which pulls material in through the suction line. After filling the tank, the pump switches to positive pressure, pushing the material out through the discharge line.

The larger GNSP-40B can operate in both manual and automatic modes, while smaller models such as the GNSP-10B and GNSP-20B operate in automatic mode only. Since no electrical power is needed, these pumps are ideal for explosion-proof environments such as oil and gas and coal mining industries.

GN Industrial Vacuum Cleaner for Tough Jobs

In addition to the vacuum pump, GN Separation also offers the GN Mini Vacuum Cleaner for smaller-scale industrial clean-up tasks. This mobile and lightweight air-operated vacuum cleaner provides high suction power and can automatically switch between suction and discharge, making it perfect for tough industrial cleaning jobs.
