Overview of G-type explosion-proof single screw pump products

The G-type single screw pump has been widely used in developed countries, mostly referred to as the "Monopump" or "MONOPPS" in foreign countries, and as the "eccentric rotor pump" in Germany. Due to its excellent performance, its application scope in China has been rapidly expanding in recent years. Its major features are strong adaptability to the medium, stable flow rate, small pressure pulsation, and high self-priming ability, which cannot be replaced by any other pump type. We have conducted analysis and research on single screw pumps produced abroad (such as Germany, England, France, Japan, etc.) and products in the same industry domestically, drawing on the strengths of others and continuously reforming and innovating our own products. At present, our company's products have formed their own system, with pressures ranging from 0.4 to 1.2 MPa, which can meet the different needs of users for single screw pumps. The pumps produced by our unit have reliable quality, implement three guarantees, and relatively low prices, while ensuring the normal supply of spare parts. Our unit warmly serves our customers and accepts design and manufacturing tasks for single screw pumps with special requirements.

The significance of G-type explosion-proof single screw pump model

Application scope of G-type explosion-proof single screw pump

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, with a head of 60m (for clean water) and a self-priming height generally above 6m. 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. This pump has a compact structure, small volume, and easy maintenance. Strong adaptability to media, stable flow rate, small pressure pulsation, and high self-priming ability. The working temperature can reach 120 ℃. If you need to transport high-temperature media between 120 ℃ and 350 ℃, it can be customized. Widely used in industrial sectors such as food, metallurgy, papermaking, printing and dyeing, chemical industry, fertilizers, pharmaceuticals, etc.
