- Product Description
G Series screw pump with continuously variable transmission is a new pump based on turning meshing volumetric principle, the main working parts of which are eccentric screw rod (rotor) and fixed bushing (the stator). Because of the special geometry of the two components, they form separate sealed cavities respectively, the medium flow uniformly along with the axial direction. The low internal flow rate, unchanged volume, and stable pressure, which result no eddy or stirring.The output pressure for each stage pump is 0.6MPa, and head is 60m(water). It is suitable for conveying the medium below the temperature 80 ℃ (up to 150 ℃for special requirements). Due to the stator made from a variety of flexible materials, it is applicable for the delivering of high-viscosity fluids, and the liquid with hard suspended particle or fiber, so that the pump has many characteristics which is lacked by other common pump. Its flow is proportional to therational speed. The transmission is fulfilled by coupling directly, or the speed is changed by the control motor, triangular belt, gearbox and other unit. The pump has many advantages, such as fewer parts, compact structure, small size, easy maintenance, and as the wearing parts of pump, the rotor and the stator have simple structures, and are easy to assemble and disassemble.
- Product Application
G Series screw pump with continuously variable transmission is particularly suitable for the following operating conditions:
- High-viscosity media conveyed;
- Media with solid particles or fibers conveyed;
- Requiring continuity, stability in pressure, and no cyclical pressure fluctuations;
- Requiring little stir, not to destroy the natural structure of the conveyed media;
- Low noise.
