Description
1. Overview of KNKE Stainless Steel Screw Pumps
The KNKE Stainless Steel Screw Pump uses the meshing of the screw and casing to create volume changes. This movement generates suction and discharge for fluid transport. The pump consists of a stator (casing) with a double-helix cavity and a rotor (screw) that meshes with the stator. As the rotor rotates around the stator, it creates sealed chambers. These chambers move fluid from the suction side to the discharge side.
The stator’s inner surface features dual threads. The cross-section forms an elongated oval. The ends are semi-circular, with a radius (R) matching the screw’s cross-sectional radius. The rotor creates a series of sealed chambers inside the stator. As the rotor turns, the volume of each chamber increases, forming a vacuum. The pressure draws in fluid, and the rotor pushes it toward the discharge side. This process continues smoothly, ensuring stable fluid transport.
