This pump can be completely submerged in the pumped liquid; therefore, it is applicable in conditions of limited spaces, very deep tanks and wells, etc. Alfa submersible pumps are also manufactured from these materials such as ductile iron or superalloys with high abrasion resistance, depending on industrial applications. Housings can be covered from the inside with anti-abrasive rubber. Submersible flow rate range pumps ranges from 100 l / min to about 4000 l / min, with head up to more than 30 m water column. They find application in situations where the well is very deep or is under the floor of the production area, or when there is little space for installation and subsequent maintenance of other types of pumps.
