G gear change screw pump

G gear change screw pump Product Overview: The single screw is a new type of pump that works according to the principle of twisting and meshing displacement. The main working parts are the eccentric screw (rotor) and the fixed bush (stator). Due to the special geometry of the two components, a separate sealed chamber is formed, the medium is uniformly pushed by the axial flow, the internal flow velocity is low, the volume is maintained constant, and the pressure is stable, so that vortex and agitation are not generated. Each stage of the pump output pressure is 0.6MPa, head 60m (clean water), self-priming height is generally 6m, suitable for transmission medium temperature below 80 °C (special requirements up to 150 °C).


Features

       Because the stator is made of a variety of elastomeric materials, this type of pump is characterized by the inability of a general pump to transport high-viscosity fluids and to transport hard-suspended particulate media or fiber-containing media. Its flow is proportional to the speed. The transmission can adopt the direct drive of the coupling, or use the speed-adjusting motor, the V-belt, the gearbox and other devices. This kind of pump has few parts, compact structure, small size and easy maintenance. The rotor and stator are the vulnerable parts of the pump. The structure is simple and easy to install and remove.

Product Usage

        Widely used in food and metallurgy, paper making, printing and dyeing, chemical, chemical fertilizer and other industrial sectors. Transmission can be coupled with direct drive transmission, or the use of high-speed motor, V-belt, gearbox and other devices speed.
