We supply a wide range of well & borehole submersible pumps suitable for domestic, agricultural, industrial and horticultural applications. From a slim line 3" borehole pump up to 4", 6", 8", 10" or larger, for large diameter wells & boreholes.
Although deemed to be a modern type of pump, their history can be traced back to over 60 years. Of course nowadays we have a much wider choice of materials and designs. We at ECP Group only select pumps which meet our exacting standards. One of the reasons being that as we overhaul the pumps ourselves it is essential that they are service friendly resulting in a shorter down time for their repair.
Quick Crash Course on Borehole Submersible Pumps
Firstly a submersible pump is installed below the water level and comprises of two components; the electric motor and the pump end (wet end). Incredibly the motor is designed to work underwater quite often with water lubricated bearings. Modern motor windings are usually completely sealed with a welded stainless steel enclosure tube and in normal use it is impossible for water to enter the windings.
The wet end is comprised of a series of impellers stacked on top of each other. The impellers driven by the motor rotate allowing water to travel from one impeller to the next increasing the pressure (head) as it travels through the pump, finally pushing the water up through the rising main to ground level and then into the distribution system. End of crash course!
Quick Crash Course on Well Type Submersible Pumps
A well type submersible pump consists of a single unit usually enclosed within a stainless steel tube. Within this tube, the impellers are at the base with the motor coupled on top. This arrangement ensures that the motor is adequately cooled by the water as it passes over it. This type of pump relies on mechanical seals preventing water from entering the motor winding.
The impellers carry out the same function as with the borehole submersible pump and once installed it is virtually impossible to distinguish one from the other. The main advantages of the well type submersible are primarily cost and the fact that the intake of the pump being at the base allows a greater depth of water to be utilised in the well or tank. End of crash course!!!
All pumps are available in both 1ph and 3ph variants, there are pros and cons for both but that’s another story for another day.
Taking the above into consideration, we at ECP Group select suitably sized pumps to deliver the required flow and pressure to the tap or sprinkler, based upon the depth of the pumping water level including friction losses and required head. I know it all sounds rather confusing, don’t worry we have been doing this for over 40 years and that is why we are here to help.
