A submersible pump, electric or solar works fully submerged under
water. It is designed with a rust-proof metal body inside which is planted a
motor in a hermetically sealed cavity. This motor is connected closely to the
pump.
The way the pump works is through
conversion of energy, a process common in all pumps. Only in this case, its
rotary energy that the pump changes into kinetic energy and then finally to
pressure energy which helps it push the water up. This chain of conversion is
carried out with the help of water which it draws from its environment. This
water is then passed through the pump and pushed upward with the power of the
rotating impellers. Once through the integrated diffuser, the water hits the
surface and collects in the container put there for the purpose.
While the function is pretty
simple, it is highly effective and consistent. The greatest advantage however
is that a submersible pump needs no priming.
The pump, already being dunked in fluid requires no additional protection from
the outside.
Submersible pumps sell worldwide
and in large quantities chiefly because of their energy-saving nature. These
systems although surprisingly efficient do not require proportional energy. The
motor functions using the pressure of water itself, thus saving electricity in
the process. In case of a solar bore water pump, it’s solar energy it saves.
But fluid is not the only thing
these pumps are designed to pump. There are models that handle solids too, and
those that are water pumps dedicatedly handle fluids only. These pumps, unlike
aboveground models are not noisy. Under the water, they are very quiet. Also,
cavitation is well taken care of in these pumps. With uniform water flow, there
is never any difference in pressure.
Submersible pumps are designs for
a specific section of users, and therefore it’s no surprise that they don’t
work for everybody. If you are looking for a pump to use at home, pick a
single-stage model. These pumps are great for home uses as well as light
industrial uses. These models work as great as sum pumps, for sewage pumping
and for filtering aquariums. A multi-stage pump on the other hand is great for
all things underground. You can use these in wells to pull water, but also oil
wells to draw oil. These pumps work great with water and other thin liquids,
but they are also equipped to handle thicker fluids like sewage water, oil,
etc.
While using a submersible pump, you must make sure
that the machine remains fully submerged at all times. It is the fluid that it
is sunk in that helps keep the motor cool while running. Above water, the motor
tends to overheat and that is detrimental to the life and function of the pumps.
The market today has a huge
selection of submersible pumps, both electric and solar kinds. Talk to a sales
representative to find out which model would fit your precise applications
perfectly.
