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 render.

Electric Submersible Pumps Are Made With Durability In Mind

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 efficiency.

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.
