Invention Patent Carbon Fiber Chemical Acid Resistant Pumps for High Temperature Liquid
What is DCS
DCS is Carbon Fiber Composite Material, which can resistant to almost 99% of the chemical medium and working temperature can reach 150°C. This material is made of carbon fiber, silicon carbide, and chemically reacted with high-performance coupling agent at high temperature. SiC is the third superhard material with a Shore hardness of 9S (diamonds is 100). This synthetic material’s hardness is nearly same as diamond thanks to SiC.
Benifits of DCS Manufacture Technology
After studied the material properties, our company has found a special manufacturing process.
Thermal curing casting: The entire manufacturing process of DCS materials is carried out under vacuum and high temperature. The combination of coupling agent, tantalum carbide and carbon fiber is perfect. So far, we obtained four national invention patents for this material.
Cold-cure casting: Some pumps may have voids, and then repair materials are essential to repair it. The method is cold-cure casting, but the material properties are far less than thermal curing.

Advantage
Comparison to Other Material
A contrast test between carbon fiber composite material and material 2507: under the same condition, medium: F, CI>800ppm, containing 12%sulfuric acid and 30%solid content, and its temperature is 90℃
Features
1. Single-stage single suction horizontal centrifugal pump
2. Closed impeller, twisted blades, all heavy-duty design, with good hydraulic performance
3. The single-end mechanical seal adopts an external structure to ensure that all parts in contact with the liquid are non-metallic materials.
4. Special impeller positioning method can ensure the safety of the impeller, and It is very easy to assemble and disassemble
