product details

G-type single screw pump

Single screw is a new type of pump which works according to the principle of rotary meshing volume type. The main working parts are eccentric screw (rotor) and fixed bushing (stator).

Due to the special geometry of the two parts, separate sealing chambers are formed. The medium flows uniformly from the axial direction. The internal flow rate is low, the volume remains unchanged, and the pressure is stable. Therefore, there is no eddy current and agitation. The output pressure of each pump is 0.6MPa, the lift is 60m (clear water), and the self-priming height is generally 6m. It is suitable for conveying medium temperature below 80 ℃ (special requirements can reach 150 ℃).

Product overview

Single screw is a new type of pump which works according to the principle of rotary meshing volume type. The main working parts are eccentric screw (rotor) and fixed bushing (stator).

Due to the special geometry of the two parts, separate sealing chambers are formed. The medium flows uniformly from the axial direction. The internal flow rate is low, the volume remains unchanged, and the pressure is stable. Therefore, there is no eddy current and agitation. The output pressure of each pump is 0.6MPa, the lift is 60m (clear water), and the self-priming height is generally 6m. It is suitable for conveying medium temperature below 80 ℃ (special requirements can reach 150 ℃).

Because the stator is made of a variety of elastic materials, this kind of pump is not competent for the transportation of high viscosity fluid and medium containing hard suspended particles or fiber. The flow rate is proportional to the rotational speed.

Transmission can be directly driven by coupling, or speed control motor, V-belt, gearbox and other devices.

This kind of pump has the advantages of less parts, compact structure, small volume and easy maintenance. The rotor and stator are vulnerable parts of the pump, and the structure is simple and easy to assemble and disassemble.

The G-type screw pump has the advantages of compact structure, small volume and easy maintenance. It has strong adaptability to medium, stable flow rate, small pressure fluctuation and high self absorption ability. The working temperature can reach 120 ℃. If it is necessary to transport 120 ℃ - 350 ℃ high temperature medium, it can be customized. It is widely used in food, metallurgy, papermaking, printing and dyeing, chemical industry, chemical fertilizer, pharmaceutical and other industrial sectors.
