Application of KCB stainless steel gear pump as phosphoric a

Stainless steel gear pump varieties, according to its principle of action can be divided into vane pump, displacement pump, rotary pump.

According to the production process or product characteristics can be divided into high pressure methylamine pump, low temperature pump, phosphoric acid material pump, etc.

Phosphoric acid slurry pump basically realized domestic production

Phosphorus fertilizer production process needs transport platform main phosphate ore pulp, phosphoric acid slurry, various concentrated filtrate phosphoric acid dilute acid, concentrated sulfuric acid, sulfuric acid and fluorosilicic acid, pump is susceptible to medium corrosion and erosion corrosion or wear.

Phosphoric acid slurry pump is a general term of phosphate fertilizer production process pump, is a very representative strong corrosion and wear resistance pump.

In the early stage of the development of phosphate fertilizer industry, commonly used anti-chemical corrosion pump, some life is only a week, so at home and abroad to do a lot in the design of phosphate slurry pump, material test experts, sealing research and development.

In the design of the phosphate slurry pump, we first have to solve the problem of corrosion and erosion corrosion or wear.

Therefore, special consideration should be given to the structural design and the matching of the pump shell and impeller.

Foreign phosphoric acid feed pumps are based on metal materials in different series of media cases.

Domestic factories and scientific research units they also use a variety of materials corrosion and wear research resistance, to create their own ferritic stainless steel, dual-phase steel, austenitic stainless steel and other material series.

Many domestic phosphoric acid slurry pump professional manufacturers, but also the Chinese Academy of Sciences, universities, design institutes, research institutes and other participation in scientific research and development, localization problems of phosphoric acid slurry pump has been basically solved.

China has built large, medium and small phosphate compound fertilizer production projects, large and medium-sized devices related to all kinds of slurry pumps, in a small device, for all kinds of slurry pumps, according to each pump for 6 months the average life, the market space is relatively large.

In addition, there are some large domestic chemical fertilizer production enterprises just built or still in the progress of infrastructure, coupled with some small and medium-sized AP renovation and expansion projects, domestic chemical fertilizer provides a broad market space for pumps.
