GBY series submerged pump is a new concentrated sulfuric acid submerged pump which is produced according to the performance parameters of FY submerged pump and improved by material design. Compared with domestic traditional concentrated sulfuric acid pump, this pump has unique characteristics and low price. It is a good choice for the drying tower and the absorption tower circulating sulfuric acid pump in the production of sulfuric acid.

GBY type concentrated sulfuric acid submerged pump overview

      GBY series submerged pump is a new concentrated sulfuric acid submerged pump which is produced according to the performance parameters of FY submerged pump and improved by material design. Compared with domestic traditional concentrated sulfuric acid pump, this pump has unique characteristics and low price. It is a good choice for the drying tower and the absorption tower circulating sulfuric acid pump in the production of sulfuric acid.

GBY type concentrated sulfuric acid submerged pump features

1. The structure is reasonable.

2. The materials are selected from special cast iron and carbon steel, which are economical, practical and energy efficient.

3, the use of open impeller, for the transport of liquid containing particles, (particle diameter does not exceed 30% of the pump suction diameter is appropriate), stable operation, no blockage

      GBY-type concentrated sulfuric acid submerged pump special steel is widely used in 80-100% sulfuric acid, the temperature can reach 60-80 °C. Steel in this concentration and temperature range of sulfuric acid, the surface can produce a protective layer of ferric sulfate. Cast iron is not suitable for use in more than 100% fuming sulfuric acid, probably due to the reaction of sulfur trioxide with the silicon contained in iron to make the cast iron brittle. Carbon steel is not suitable for 100-102% fuming sulfuric acid, and more than 102% acid is suitable, and the temperature is limited to about 60 °C. Dilute sulfuric acid has a great corrosion to steel. When the acid concentration is about 47%, the corrosion rate reaches a high value. When the acid concentration is greater than 65%, the corrosion rate of steel is significantly lowered. However, in the concentration range of 65 to 80%, it is better not to use steel to make it safer to use lead or other dilute acid resistant materials.

Sulfuric acid concentration: 80% to 98% Special cast iron temperature: 25 to 50 degrees, special carbon steel temperature: 25 to 60 degrees.
