The 3QGB Insulated Screw Pump is a容积式泵，boasting significant advantages such as simple structure, compact size, and the ability to operate smoothly and reliably at high speeds. It features minimal pressure pulsation, stable flow rate, low noise, and high efficiency. This is achieved by utilizing the screw meshing principle, where rotating screws mesh within the pump casing, sealing the medium to be conveyed within the meshing chamber and propelling it continuously and uniformly along the screw shaft to the discharge outlet, 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 liquid 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 direction of the pump's inlet and outlet is generally as shown in the drawings, with the outlet on the right and the inlet on the left upon factory shipment. Special requests for left-in/right-out configurations can also be accommodated.

3QGB Insulated Screw Pumps are widely used in various industries such as petrochemical, fiber, metallurgy, machinery, electricity, machine tools, ships, glass, and highways.

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