The 3QGB series three screw pump has good sealing performance and adopts mechanical seals. Different materials are selected for the friction parts of the mechanical seal according to the user's different media. For high viscosity media, hard alloy materials with high mechanical strength and good wear resistance are selected to ensure sealing performance at high temperatures.

The 3QGB series three screw pump is a positive displacement pump with significant advantages such as simple structure, small volume, smooth and reliable high-speed operation, low pressure pulsation, stable flow rate, low noise, and high efficiency. It is precisely by utilizing the principle of screw engagement, relying on the rotating screw to mesh with each other inside the pump sleeve, that the conveyed medium is enclosed in the engagement chamber and continuously and uniformly pushed along the axial direction of the screw to the discharge port, providing stable pressure for the system.
