The working principle of the 2GR twin-screw pump is to form a sealed space by rotating two screws in the pump body. As the screw rotates, the volume of these sealing spaces gradually increases and pushes the liquid from the suction end to the discharge end. Due to the rotation of the screw at equal speed, the flow of liquid outflow is uniform, ensuring the stability of the flow and the increase of pressure. It is suitable for a wide range of media, which can transport low viscosity or high viscosity media, and even media containing particles and corrosive substances. The twin-screw pump has self-priming ability and is suitable for various complex working conditions.
