Submersible dredge pumps are also called submersible sand suction pumps, submersible dredging pumps, submersible slurry pumps, submersible mud pumps, etc. The listed various names are commonly called by customers according to different working conditions, that is, what environment or what kind of process is called. The original dredge pump type was specially designed by OCEAN PUMP technical team in the 1990s for sand pumping and dredging of the Yellow River. Later, after continuous technical improvement, it was suitable for use under a variety of working conditions. As a result, many manufacturers are competing to imitate, and there are many low-quality products. The so-called submersible dredge pumps of most manufacturers are almost unusable, or will soon be scrapped. In order to give users a comprehensive understanding, we will introduce in detail the comprehensive characteristics of the submersible sand pump, as well as the improved technology in various environments, so as to be suitable for applications in different working conditions.
OCEAN PUMP brand submersible dredge pump is mainly composed of three parts: pump head, electric motor, oil chamber, and combined seal. The water conservancy part is designed with advanced hydraulic models combined with modern computer technology systems. The motor and the water pump are coaxially submerged into the medium to work. The flow parts (including the pump body, guard plate, impeller, shaft sleeve, etc.) are made of wear-resistant alloy materials (CR28), and the technical requirements are reached through three heat treatment processes after casting. Only very few manufacturers can do this. The product has the characteristics of excellent material selection, advanced structure, wide flow channel, strong passing capacity, and large passing particle size. Submersible sand pumps are widely used in engineering projects such as metallurgy, chemical industry, mining, coal, electric power, building materials, municipal environmental protection, and dredging of rivers, lakes, reservoirs, and ports. It is used to transport liquids containing abrasive and strong abrasive solid particles such as sand, gravel, silt, cinder, tailings, etc.
