The 3QGB insulated screw pump is a positive displacement pump with notable advantages such as a simple structure and compact size. It allows for high-speed operation that is smooth and reliable, with minimal pressure pulsation, stable flow rate, low noise, and high efficiency. It operates based on the screw meshing principle, where rotating screws mesh within the pump casing, encapsulating the medium being conveyed in the meshing chamber and continuously and uniformly pushing it along the screw shaft to the discharge outlet, providing a stable pressure for the system.

The 3QGB insulated screw pump is suitable for transferring various non-corrosive oils and similar liquids, with the viscosity of the transferred liquid 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 insulated and non-insulated versions. It is recommended to use the insulated screw pump for high-viscosity media. The direction of the pump's inlet and outlet is usually as shown in the diagram, with right-in and left-out upon factory shipment. Special requirements can also be accommodated with left-in and right-out configurations.

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

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