GBL type vertical concentrated sulfuric acid centrifugal pumpDetailed product description：

GBL concentrated sulfuric acid pump is optimized and designed based on the performance parameters of ISG centrifugal pump, using specialized cast iron and carbon steel materials for concentrated sulfuric acid and excellent hydraulic models. It is an ideal new generation chemical pump and is widely used in the transportation of concentrated sulfuric acid medium in major chemical enterprises.

Main Features
1. The pump is a vertical structure with the same inlet and outlet diameters and located on the same centerline. It can be installed in pipelines like a valve, with a compact and beautiful appearance, small footprint, and low construction investment. If a protective cover is added, it can be used outdoors.
2. The impeller is directly installed on the extended shaft of the motor, with a short axial dimension and compact structure. The pump and motor bearings are reasonably configured, which can effectively balance the radial and axial loads generated by the pump operation, ensuring smooth pump operation and low vibration noise.
3. The pump shaft seal adopts an external high-quality mechanical seal, and the dynamic and static rings are made of new hard alloy and ceramics, which are wear-resistant, leak free, and have a long service life.

Selection criteria
GBL type concentrated sulfuric acid centrifugal pump specialized steel is widely used for 80-100% sulfuric acid, with temperatures reaching 60-80 ℃. Steel in this concentration and temperature range of sulfuric acid can produce a protective iron sulfate film layer on its surface. Cast iron is not suitable for more than 100% fuming sulfuric acid, possibly due to the reaction between sulfur trioxide and the silicon contained in iron, which makes the cast iron brittle. Carbon steel is not suitable for 100-102% fuming sulfuric acid, and is suitable for acids exceeding 102%. The temperature limit is about 60 ℃. The corrosion of steel by dilute sulfuric acid is significant, and the corrosion rate reaches its highest value when the acid concentration is around 47%. When the acid concentration exceeds 65%, the corrosion rate of steel significantly decreases. But in the concentration range of 65-80%, it is better not to use steel, and it is safer to use lead or other acid resistant materials.
