Industrial Ceramic Desulfurization Pump Caliber: 900mm

We are a most trusted name among the topmost companies in this business, involved in manufacturing, exporting, offering and supplying of Industrial Ceramic Desulfurization Pump in Shenyang, Liaoning, China.

Ceramic Desulfurization Pump Details:

Advanced ceramic desulfurization is a large-flow, low-lift, cantilever single-stage centrifugal pump. Particularly suitable for conveying highly abrasive and corrosive media. Its core technology is based on the metal efficient hydraulic model, using CFD design means, using the solid-liquid two-phase flow hydraulic design method, unique "ceramic + metal" composite manufacturing process.

Ceramic material
Ceramic materials are professional and reliable. According to the characteristics of the conveying slurry, a ceramic material with high strength, wear resistance and corrosion resistance was developed. The unique injection molding technology was used to ensure the reliability of the combination of ceramic materials and metal components. The abrasion resistance test of the comparative material of the Institute of Casting and Wear-resistant Materials of Xi'an Jiaotong University shows that the wear resistance of silicon carbide ceramic material is 3.5 times higher than that of high chromium alloy (Cr30).

2.2 Ceramic pump lining
With optimized design and special manufacturing processing technology, silicon carbide ceramics are used for the pump housing and the pump cover lining. The external use of metal armor makes the pump highly reliable, safe, and easy to disassemble and install. The special ingredients and technology of ceramic materials ensure that the metal shell and the ceramic lining are integrated and tightly combined.

2.3 Ceramic impeller
The impeller is an in-line metal hub structure and the outer complex silicon carbide ceramic is manufactured as a whole. Fundamentally ensured the mechanical strength of the impeller and the wear and erosion of the crucible.
The impeller can be adjusted axially to maintain the impeller in a reasonable position in the pump chamber, thus ensuring that the pump operation is always in an efficient and stable state.

2.4 Shaft seal
The seal can move axially as a whole. The mechanical seal ring can move axially, and the mechanical seal static ring is fixed on the pump casing. It is better than the foreign product. The mechanical seal static ring is fixed on the front cover of the bearing chamber, which can avoid the radial runout of the mechanical seal after adjustment and lead to the mechanical seal. damage.

2.5 Pump Structure

The pump design uses a back-pull structure. When disassembling the impeller, mechanical seal and shaft assembly during maintenance, it is not necessary to disassemble the entire pump. The bearings are lubricated with oil to ensure stable operation. The bearing part is composed of a bearing bracket and a bearing body. The bearing body can be moved axially on the bearing bracket to facilitate adjustment of the clearance and position of the impeller.

1) Domestic initiative. Large-scale ceramic desulfurization pumps are a blank in China, and advanced ceramic desulfurization pumps are the first in China.

2) The performance is stable without attenuation. In the initial operation, the performance of the pump is comparable to that of other domestic manufacturers. However, the ceramic pump can be basically not worn during the entire life cycle, and it can ensure stable performance without attenuation.
