How To Choose The Right Material For Slurry Pump Parts

What are the materials for slurry pumps? How to choose wear-resistant or corrosion-resistant? According to the common saying in the industry, the materials of slurry pumps are metal and rubber. Metal and rubber materials can be divided into many categories. Different materials should be selected according to different working conditions. The common metal material is A05 and the rubber material is R55. What are the materials of slurry pumps Metal: A05, A07, A33, A49, Cr30, 304 stainless steel, 316 stainless steel, duplex stainless steel Rubber: R55, EPDM, Hypalon, Resin: Polyurethane, Polyether Ester The above categories are various materials commonly used in slurry pumps, among which A05, A49, and R55 are the most widely used. The characteristics of the slurry pump determine the choice of slurry pump material. The slurry pump is a centrifugal pump that transports slurry containing solid particles. Because it is not a pure liquid, it is generally required to have good wear resistance. Therefore, the first attribute of the above slurry pump material should be wear resistance. However, in many special working conditions, we have to give up a certain wear resistance and sacrifice wear resistance. Selection of slurry pumps for conveying corrosion-resistant media In many cases, the slurry we convey not only contains solid particles but also contains corrosive characteristics When selecting the material of the slurry pump, it must be based on the characteristics of the conveyed slurry. Expensive ones are not necessarily good, and suitable ones are good For example, if we use stainless steel to convey abrasive slurries, it is a waste and the effect is very poor; It is also undesirable for us to use A05 material slurry pumps to convey highly corrosive slurries. For example, nitrates, sulfuric acid, and strong alkaline slurries are very corrosive and are generally between PH0-3 and PH12-14. Because materials with good wear resistance may not necessarily have good corrosion resistance, we must give up materials such as A05 and R55 at this time, and choose more special and rare materials such as A49, Cr30, 304 stainless steel, 316 stainless steel, duplex stainless steel, EPDM rubber, and Hypalon with better corrosion resistance. The price of these materials is generally 1-3 times higher than that of ordinary materials, or even more. How to choose the material of slurry pump 1. Slurry with small acidity and alkalinity and sharp-angled particles: A05, A07, common in metal mines and coal washing, mainly used slurry pump models: ZJ slurry pump, AH slurry pump, ZGB slurry pump; 2. Slurry with small acidity and alkalinity and no sharp-angled particles: R55 rubber material, common in metal mines and coal washing, mainly used slurry pump model: AH slurry pump; 3. Slurry with high acidity and alkalinity and strong corrosiveness with more particles: A49, Cr30, common in power plant desulfurization industry; 4. Slurry with strong acidity and alkalinity, low temperature and certain abrasiveness: choose EPDM rubber and Hypalon rubber material, common nitrate transportation; 5. Slurry with strong acidity and alkalinity, low abrasiveness and not too high temperature: choose stainless steel material; The material selection of slurry pump is based on high cost performance and appropriateness!
