Material selection for catalytic slurry pumps
Thread Content
Option 1: The pump body is made of 1Cr13 stainless steel, while the parts that are exposed to flow (such as the volute and impeller) are treated using the penetration of nanodiamond technology. The thickness of the coated layer can range from 0.3 mm to 3 mm, and its hardness can reach 45–65 HRC. This coating provides resistance to corrosion, erosion, and high temperatures (up to 600°C). The treatment process involves submerging all the components in a penetrant before placing them together in a furnace for heat treatment, thereby ensuring that all parts exposed to flow are coated. The expected service life is 3 to 5 times that of a regular lined pump. For situations where the pumped medium contains catalyst particles, taking into account the material’s corrosion resistance and erosion resistance, the nano-penetrated diamond technology is employed. Option 2: The entire pump body is made of 1Cr13 stainless steel, while the parts that are subject to flow (such as the volute and impeller) are treated using supersonic flame spraying with tungsten carbide; this method provides good corrosion resistance and strong adhesion, and an expected service life of 6 years can be achieved. Re-spraying can be carried out on-site after 6 years. Option 3: Materials for the main components of the slurry pump. Outer casing: ZG1Cr13Ni; Inner casing: KmTBCr15; Impeller: KmTBCr15; Shaft: 4Cr144mO. Which of these three options do you think is the best?
Whoever comes up with the idea is the one who creates it, right?:lol

I’m very curious to know whether you are a senior engineer or a graduate supervisor, and whether your proposal has undergone any validation or feasibility analysis Are you engaged in research or something similar, or are you preparing to write a paper or develop a patent? Even if you manage to produce it, are the market prospects, supply and demand dynamics, and price positioning clear?
