Overview of GF Stainless Steel Sanitary Single Screw Pump
Single screw pumps have been widely used in developed countries, with most foreign countries referring to them as "Monopumps" or "MONOPPS", and Germany referring to them as "eccentric rotor pumps". 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 GF stainless steel sanitary single screw pump model

Scope of use of GF stainless steel sanitary single screw pump
Generally speaking, a single screw pump can be used as a universal pump. The operating speed can be high or low, and the rated outlet pressure of the pump can increase with the number of pump stages. For each additional stage, the pressure increases by 0.6 MPa. Therefore, it has a wide range of applications: environmental protection, shipbuilding industry, petroleum industry, medicine, daily chemical industry, brewing industry, construction industry, mining industry, chemical industry, printing industry, and paper industry.
