Product details

Introduction to small stainless steel corrosion-resistant centrifugal pump:

The SFB series of small stainless steel corrosion-resistant centrifugal pumps and small stainless steel corrosion-resistant self-priming pumps are self-priming pumps and centrifugal pump products independently developed by our company. The impellers of the two sided three blade series pumps are sometimes in a semi open structure or a closed structure. In addition, the connection between the stainless steel centrifugal pump and the motor has two types: straight and bearing bracket. The shaft seals of all stainless steel corrosion-resistant centrifugal pumps adopt the advanced cantilever technology mechanical seals in West Germany. Due to the excellent structure, performance, and shape of our products, as well as the use of high-quality stainless steel materials for overcurrent components and connecting frames, the two series products have reliable corrosion resistance, easy use and maintenance, compact structure, and energy consumption. A series of advantages such as low cost and good sealing performance.

Main applications of small stainless steel centrifugal pumps
The small corrosion-resistant pump can transport liquids with small soft particles or fibrous materials, corrosive or hygienic requirements, with a temperature not exceeding 90 ℃ for direct connection or not exceeding 105 ℃ for bearing bracket type. The SFBX series pump also has self-priming performance. Both series pumps are widely used in industries such as food, beverage, medicine, sewage treatment, chemical industry, electroplating, bleaching and dyeing, and fine chemical industry.
