This series of pumps belongs to single-stage single suction cantilever centrifugal pumps, and the overcurrent components are made of steel lined ultra-high molecular weight polyethylene (UHMWPE). This material is currently the new generation of corrosion-resistant and wear-resistant engineering plastics for pumps internationally. Its most prominent advantages are its excellent wear resistance, impact resistance (especially with low-temperature impact), denaturation resistance (resistant to environmental stress cracking), and excellent corrosion resistance among all plastics. The significant feature of this pump is its versatility, which means that it can adapt to various working conditions, such as transporting acid, alkaline clear liquid or slurry; Various corrosive slurries in the smelting industry; Various dilute acids in the sulfuric acid industry; Various types of wastewater in the environmental protection industry. This pump is both corrosion-resistant and wear-resistant, and has a wide range of applications. The pump has been widely used in acid slurry and dilute acid positions in more than 30 large non-ferrous smelting and sulfuric acid enterprises, including Guixi Smelter in Jiangxi, Baiyin Company in Gansu, and Huludao Zinc Plant in Liaoning. Its corrosion resistance, wear resistance, sealing reliability, and service life have all received high praise.
