The oil immersion type submersible pump is a portable shallow water drainage and irrigation equipment combining pumps and machines. Its feature is that the motor is filled with mechanical oil, which improves the working conditions of the mechanical seal, and the external water is less likely to enter the motor. The oil quickly conducts the heat coming from the motor and has a good cooling effect, which greatly reduces the temperature rise of the motor, thus increasing the overload capacity of the submersible electric pump. In addition, the bearings of oil-immersed submersible electric pumps are immersed in oil, and the lubrication and cooling are guaranteed, so the bearing life is longer than other types of submersible electric pumps.

During the daily use of the self-priming pump, there will be some more common problems. For example, the self-priming pump's non-pumping problem will be caused by many different reasons, so how do we deal with these problems is the key. The reasons why the self-priming pump does not pump water include the following aspects.
The hot water submersible pump is used for hot spring bathing, and can also be used for extracting groundwater from deep wells, and can also be used for water lifting projects such as rivers, reservoirs, and canals. It is mainly used for farmland irrigation and human and animal water in high mountain areas. It can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines, and construction site drainage. The general flow rate can reach 5~650m³/h, and the head can reach 10-550 meters.
Diaphragm pump is a new type of conveying machinery that can convey various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids. Diaphragm pump has four materials: plastic, aluminum alloy, cast iron, stainless steel.
