Deep well submersible pumps

Submersible series pump is vertically submerged under water and driven by electric. It connects pump body and motor in to a whole one. It is suitable for conveying liquid with slurry, solid particles of gravel, cinders, tailings and groundwater or hot water extraction for irrigation, municipal water use, etc. There many kinds of submersible pump for choose according to different situations for example, some special work may need submersible sewage pump. Inside the motor line packaged with oil-immersed, water immersion and dry-type, check the instructions first before use can not go wrong.

According to medium, submersible pump generally divided into four types: submersible clear water pump; submersible sewage pump; submersible sea water (corrosive water) pump; submersible sand slurry pump. The installation of submersible pump includes: vertical ----such as the general wells; inclined ----such as in the mine with inclination; horizontal ---- such as in the river or lake.

The submersible pumps used in installations are centrifugal pumps operating in a vertical position. Although their constructional and operational features underwent a continuous evolution over the years, their basic operational principle remained the same. Produced liquids, after being subjected to great centrifugal forces caused by the high rotational speed of the impeller, lose their kinetic energy in the diffuser where a conversion of kinetic to pressure energy takes place. The pump shaft is connected to the gas separator or the protector by a mechanical coupling at the bottom of the pump. An optional thrust bearing takes up part of the axial forces arising in the pump but most of those forces are absorbed by the protector’s thrust bearing.
