The 3QGB insulated screw pump is a positive displacement pump with significant advantages such as simple structure, compact size, and high-speed operation with smooth and reliable performance. It features minimal pressure pulsation, stable flow rate, low noise, and high efficiency. It operates based on the principle of screw meshing, where rotating screws intermesh within the pump casing, encapsulating the medium being transported within the meshing chamber and continuously pushing it along the screw's axial direction at a uniform speed, providing the system with stable pressure.

The 3QGB insulated screw pump is suitable for conveying various non-corrosive oils and similar liquids, with the viscosity of the conveyed fluid typically ranging from 3 to 760 mm/s. High-viscosity media can be transported after being heated to reduce viscosity, with the temperature generally not exceeding 350°C. The 3GB insulated screw pump is made of cast steel and is available in insulated and non-insulated versions. It is recommended to use a pump with an insulated structure for high-viscosity media. The pump's inlet and outlet directions are generally right in and left out as per the illustrated direction upon factory shipment. Special requirements from customers can also be accommodated with left in and right out configurations.

The 3QGB insulated screw pump is widely used in various industries including oil, chemical fiber, metallurgy, machinery, power, machine tools, ships, glass, highways, and more.

The 3QGB Insulated Screw Pump is suitable for transporting fuel oil, lubricating oil, hydraulic oil, heavy oil, asphalt, and other similar lubricating liquids.
