Electric Submersible Pumps
Electric submersible pumps are expensive for they are highly engineered. These
pumps are created to be reliable, strong and able to withstand operating under difficult environments. Many major
companies depend on electric submersible pumps despite the costs because of the high performance that these pumps
Electric Submersible Pumps Are Made With Durability In
People depend upon electric submersible pumps to pull water from the ground into their
households and to move the water for irrigation and livestock. Once put in place, these electrical submersible
pumps are expected to perform for long periods of time and not to be taken out for repairs. Extricating the system
from installation requires special equipment and the skill of professionals.
It is for this reason that companies manufacturing these pumps spend a lot on research to
produce pumps and parts that are durable and that can withstand wear and tear for years to come. These pumps and
parts must be able to withstand difficult environments. The pump has to be submerged in water hence its electrical
parts must be tightly sealed to prevent water from damaging the electrical parts and causing a burn out. The
electric submersible pumps are also subjected to different water pressures that may ordinarily hinder its
Components Of Electric Submersible Pumps System
The main parts of the electric submersible pumps system consists of the pump, motor, assembly, power supply and control, lightning
and surge protector, electrical drop cable, and motor cooling. If not bought as a package, you have to ensure
the pump rating must match that of the motor. If the motor and pump are not yet assembled when purchased, they
must be cleaned well and uneven paint fixed before mounting them together using the assembly.
Care is needed when mounting as a mistake in the position may put additional stress on the
brackets and shafts. The power supply and controls including the fuse, motor overload protection and circuit
breaker must also match the motor. The lightning and surge protection or lightning arrestors must be properly
grounded. Motors of smaller electrical submersible pumps have a built in lightning arrestor.
The electrical drop cable must conform to ground motor local regulations. Finally, the pumps system must be
provided with a motor cooling system.
Buying A Complete Electric Submersible Pumps System
All these safeguards and processes can be simplified by purchasing an entire electric
submersible pumps system for this will come complete with all the parts and at
the same time all parts are compatible and compliant with local regulations or codes.
Although the entire electric submersible pumps system can be installed by someone with
basic skills, there are still some “tips” or “trade tricks” that the experts have learnt through years of
tinkering with the system. That is, tips that would prolong pump life or maximize the power of the submersible
pumps. An example is setting the pump three meters above the bottom so that there will be sufficient space for
sediment build up. If the pump is set at the bottom, it will be embedded and buried in sediment after sometime.
Clogging and stuck ups will thus occur. Another example is setting the motor at a balance. An imbalance in
anchoring the motor may cause vibration or overload trip and thus will reduce its lifespan.
