The 3QGB insulated screw pump is a positive displacement pump with notable advantages such as a simple structure, compact size, and the ability to operate smoothly and reliably at high speeds with minimal pressure pulsation, stable flow, low noise, and high efficiency. It operates based on the screw meshing principle, where rotating screws mesh within the pump casing, enclosing the medium being conveyed in the meshing chamber and pushing it along the screw axis at a continuous and uniform speed to the discharge outlet, providing stable pressure to the system.

The 3QGB insulated screw pump is suitable for transporting various non-corrosive oils and similar liquids, with the viscosity of the fluid typically ranging from 3 to 760 mm/s. High-viscosity media can be transported after heating 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 both insulated and uninsulated versions. It is recommended to use a pump with an insulated structure for high-viscosity media. The direction of the pump's inlet and outlet is generally as shown in the diagram, with the outlet on the right and the inlet on the left upon factory shipment. Special configurations, such as left inlet and right outlet, can also be made upon customer request.

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

The 3QGB insulated screw pump is suitable for transporting fuel oil, lubricating oil, hydraulic oil, heavy oil, asphalt, and other similar lubricating liquids.
