GBW Chemical centrifugal pump for concentrated sulfuric acid

GBW concentrated sulfuric acid pipeline centrifugal pump is designed and made on the basis of ISW horizontal pipeline centrifugal pump for the conveying of concentrated sulfuric acid. GBW centrifugal pump uses the special cast iron and carbon steel materials for concentrated sulfuric acid and excellent hydraulic model.

GBW concentrated sulfuric acid pipeline centrifugal pump is an ideal new generation of chemical pump. The pump shaft seal is made of high-quality mechanical seal with external mounting type, and the dynamic ring and static rings are made of new hard alloy or ceramics, which are wear-resistant, leak-free and have a long service life. It is widely used in the transportation of concentrated sulfuric acid medium in various chemical enterprises.

GBW concentrated sulfuric acid pump features:

1.smooth operation: pump shaft absolute concentricity and impeller excellent static and static balance ensure smooth operation, no vibration.

2. No leakage: the pump shaft seal adopts external high-quality mechanical seal, and the dynamic and static rings are made of new sic to sic, which is corrosion-resistant, wear-resistant, leak-free and has a long service life.

3. Low noise: the water pump supported by two low noise bearings can operate smoothly, and there is basically no noise except the weak sound of the motor.

4. Low failure rate: the structure is simple and reasonable, the key parts are matched with international quality, and the whole machine's trouble-free working time is greatly improved.

5, easy maintenance: replace the seal, bearing, simple and convenient.

6, small volume: the outlet can be left, right, up three directions, then the pipe layout installation, save space.

GBW type concentrated sulfuric acid centrifugal pump special steel used for sulfuric acid with consistency 80 to 100% and temperature up to 60 or 80℃. The special steel in this concentration and temperature range of sulfuric acid, the surface can produce a protective layer of iron sulfate film. Cast iron is not suitable for more than 100% fuming sulfuric acid, which may be due to the reaction of sulfur trioxide with the silicon contained in iron, resulting in the embrittlement of cast iron. Carbon steel is not suitable for 100 to 102% fuming sulfuric acid, more than 102% acid is applicable, the temperature limit is about 60℃. Dilute sulfuric acid has a great corrosion on steel, when the acid concentration is about 47%, the corrosion rate reaches the highest value. When the acid concentration is greater than 65%, the corrosion rate of steel is significantly reduced. So in the 65 to 80 percent range, lead or or other dilute acid resistant materials are used instead of steel material for the safe operation.

Sulfuric acid concentration: 80% to 98% special cast iron, service temperature: 25℃ to 50℃

Sulfuric acid concentration: 80% to 98% special carbon steel ,service temperature: 25℃ to 60℃.
