Pumps are employed in numerous applications due to
its efficient design and increased lifespan. However, frequent
maintenance is required to maintain the performance and lifespan of the
pumps. There are different types of pumps available that varies mainly
in its working principle.
Some important pump types that are popular presently are listed below:
Centrifugal pumps:
These
pumps are used most often in industries to transfer liquids through a
piping system. These types of pumps are used for low pressure, high
volume flow applications in the industry. The output of this pump mainly
depends on the rotational speed of the driving source. It uses a
rotating impeller to increase the pressure and flow rate of the liquid.
Industrial pumps such as centrifugal pumps should be selected properly
after analyzing the design and fabrication of the pump because small
defects may prove to be very expensive in the future.
Rotary-gear pumps:
It
is the simplest form of rotary pumps that consists of two gears laid
out side-by-side with their teeth enmeshed. There are different types of
rotary gear pumps that vary slightly in the mode of operation. To
maintain a constant flow of water it is important to have many small
teeth, while the large teeth make the pump to discharge water in an
inconsistent basis.
Reciprocating-type pumps:
It is a type
of Industrial pump that is used commonly in both air compressor and
hydraulic applications operate on the reciprocating principle. To move
the liquid in positive direction this pump requires a system of suction
and discharge valves. These types of pumps were used for steam
propulsion in the earlier days. There are many more benefits offered by
this type of pump due to its effective design.
Hydromantic pumps:
This
pump is used for water treatment system. It is also employed in
industries to treat the waste waters that are produced as the byproduct
during cleaning processes. This type of water pump needs proper
maintenance, because problems such as contamination, rusting will occur
if not frequently maintained.
Velocity pumps:
This type of
pump is mainly used, when there is a need of high intensity flow of
liquid. It uses kinetic energy to enhance the flow velocity. These types
of pumps are found in industries, agricultural field and in large scale
applications.
Valveless pumps:
As
the name implies there are no valves in this pump to regulate the flow
direction. It is used most often in engineering and biomedical sectors.
Due
to continuous execution, industrial pumps are prone to frequent
repairs. However, Industrial pump repair should be performed only by a
well trained person, because repairing is not just resolving the present
problem, but it also involves inspecting the entire pump to prevent
frequent repairs. Moreover, leakage problems might occur in the water
pumps. This leakage problem can be resolved by using mechanical seals or
mechanical packing. Remember, you must choose the pumps after several
considerations, because low quality pumps might not be reliable and its
maintenance will be very expensive.
