Product Overview:

Sanitary screw pump is a new type of pump that works according to the principle of rotary meshing displacement. The main working components are eccentric screw (rotor) and fixed liner (stator).

Due to the special geometric shape of these two components, they form separate sealed chambers, and the medium flows uniformly in the axial direction. The internal flow velocity is low, the volume remains constant, and the pressure is stable, so there will be no vortex or agitation. The output pressure of each stage pump is 0.6MPa, the head is 60m (for clean water), and the self-priming height is generally 6m. It is suitable for conveying medium temperatures below 80 ℃ (special requirements can reach 150 ℃). Due to the selection of multiple elastic materials for the stator, this pump has characteristics that general pump types cannot handle for transporting high viscosity fluids and media containing hard suspended particles or fiber media. Its flow rate is proportional to the rotational speed. Transmission can be achieved directly through couplings, or through devices such as variable speed motors, V-belts, gearboxes, etc. This screw pump has few parts, compact structure, small volume, and easy maintenance. The rotor and stator are vulnerable parts of this pump, and the structure is simple and easy to assemble and disassemble. The working principle of a single screw pump is that when the screw pump is working, the liquid is sucked in and enters the sealed space surrounded by the threads and pump casing. When the active screw rotates, the sealing volume of the screw pump is increased by the compression of the screw teeth, and moves axially. Due to the constant rotation of the screw, the liquid outflow flow rate is also uniform. The characteristics of a single screw pump are: small losses and good economic performance. High and uniform pressure, uniform flow rate, high speed, capable of direct connection with the prime mover.

Selection of rubber sleeve for G-type single screw pump:

The selection of rubber sleeve for G-type screw pump. The sleeve of the screw pump is made of rubber and is also a vulnerable part of the single screw pump. The quality of its selection directly affects the life of the sleeve. Generally, the life of the sleeve is 6-12 months under normal circumstances. If not selected properly, the sleeve may fall off from the steel pipe or the rubber may fall off. So we are required to have an understanding of the basic characteristics of rubber and its adaptability to various media. Based on our experience, we have compiled the above characteristic table.
