What are the common types of submersible pumps?

The development and use requirements of water pumps are combined with technological progress, and there are many types of water pumps. Submersible pumps can be divided into well submersible pumps, working surface submersible pumps, submersible sewage pumps, sand discharge submersible pumps, mine vertical pumps, etc.

1.Well submersible pump

Freshwater submersible pumps are multi-stage pumps, mainly used for pumping water from clay wells, earth wells or reservoirs, and are suitable for factory, mine or farmland irrigation. In 1928, the United States byron Jackson (Byron Jakson) company first developed a submersible electric pump. In the following 1930s, Germany, Britain, the United States, Japan and other countries began to produce "deep well submersible pumps".

2.Working surface submersible pump

The working surface submersible pump is a small submersible pump (single-stage pump). It is widely used in many places due to easy installation and convenient use. In 1948, Sweden Flygt (Sterbery-Flygt) developed the "working surface submersible pump" for the first time. In the 1960s, the United States, Britain, Germany, Japan, the Soviet Union and other countries also began mass production. China started to produce "working surface submersible pumps" in 1958. In the 1960s it developed into "QY submersible pumps (oil-filled)", in the 1970s it developed "QS submersible pumps (water-filled)" and in the 1980s it developed QX and DQX submersible pumps (dry type)". In the late 1980s, the "working surface submersible pump" developed rapidly, and gradually became larger and diversified. Large and medium-sized submersible pumps have been widely used in municipal, industrial and mining fields because of their outstanding advantages such as simplified pump structure and saving investment in pump station construction.

3.Submersible sewage pump

Submersible sewage pumps are mainly used to transport industrial wastewater and urban domestic sewage. Its biggest advantage is that it can discharge impurities such as paper pulp and long fibers. (So it is also called "non-clogging sewage pump"). Widely used in urban sewage treatment plants, rainwater basins, pumping stations, flood control, irrigation and drainage, etc. In 1956, Sweden's Sterbery-Flygt first developed the "submersible sewage pump", which reduced the cost of sewage stations by about half. In the late 1980s, China introduced and produced "submersible sewage pumps" from Germany, mainly including WQ, QW and AS series products. (According to statistics, the “submersible sewage pump” produced around 50,000 units in China around 1995.)

4.Sand pump

China's first "sand drainage submersible pump" was developed by Professor Wang Qingwu in 1989. The KGQ12-50 sand drainage submersible pump was developed in 1989. After years of development, the product currently produced is the fourth generation sand drainage submersible pump-mine Standing pump. The submersible sand pump is specially designed for the drainage environment rich in sediment and is a new product that fills the international gap. It has the characteristics of high head and wear resistance, and is suitable for drainage in mines, engineering excavation, emergency rescue and disaster relief, environmental protection and sand removal. Drainage in an environment rich in sediment, life expectancy is 5 to 10 times that of submersible sewage pumps and clean water submersible pumps.

5.Mine vertical pump

Mine vertical pump, the fourth generation of new submersible sand pump, is an integrated product of vertical pump and submersible pump. It can be used as a submersible pump or as a vertical pump. The concept of submersible pump is a veritable "amphibious pump". According to the development of submersible pumps, mine-use vertical pumps belong to the evolution product of submersible pumps "outlet landing ashore".
