Construction water pumps: These are important in any construction site

Water pumps have multiple uses in a construction site. It is mainly
used for clearing rainwater from a construction site or dewatering
a reservoir where some construction work will be processed. There
is no ideal construction water pump available that can suit in
every occasion, contractors or engineers use one or more water
pumps depending on the situation. These water pumps are evaluated
on the basis of their performance, buying price, maintenance cost,
and durability. Types of construction water pumps Scores of water
pumps are available. They possess different capacities and other
features. However, the water pumps used in construction works can
be broadly classified under two heads: Centrifugal water pumps
Positive displacement water pumps Centrifugal water pumps are
mainly used in construction sites while positive displacement water
pumps have a wide-ranging utility in different industries.
Centrifugal water pumps These are the most-used water pumps can be
used for displacing any kinds of thin liquids including water.
Centrifugal pumps are very helpful in removing low-density liquids
too. In this water pump, one or more rotating impellers are used
for driving water into the pump and discharge it under high
pressure. Centrifugal water pumps are available in the different
specification in the market; however, the following are the most
common types of water pumps in this genre: Axial Flow Pumps – In
this pump water enters and passes out without changing the
direction and the direction remains parallel to the rotating
impeller. These pumps do not create very high pressure inside to
discharge the water. Peripheral Pumps – These are also called
turbines. In the pump’s casing, a rim like channel is fixed around
which the impeller rotates. The impeller has blades on both sides
of the rim, as the water or liquid inside rotates repetitively, the
discharge pressure increases remarkably. Radial Flow Pumps – These
are the most used pumps in the construction industry. Water enters
the pump along the axial plane, it’s speed is enhanced by the
rotating impeller and exits at a higher pressure at the right angle
to the shaft. Radial Flow pumps function at higher pressures but
lower rates of discharge than axial Flow Pumps. Mixed Flow Pumps –
It is a combination of an axial flow pump and radial flow pump. It
exits the pump at an angle that may be anything in between 0 to 90
degrees. Jet Pumps - These pumps are normally used to extract water
from very deep reservoirs or wells. A jet pump possesses two parts,
one that is fixed under the ground for pumping water and another
above the ground for generating flow. Benefits of construction
water pumps These pumps can be used in building and bridge
construction works where water is needed constantly. A radial flow
pump or mixed flow pump is generally used if any usable reservoir
is available nearby. Otherwise, a peripheral or jet water pump may
be used to bring water from a distant place or collect it from the
underground natural water. The axial water pump is generally used
to drain water that is stored due to rain or flood on a
construction site.
