Water pumps are essential in a water supply network.
00:07
Put simply pumps,
00:08
add energy such as pressure to a fluid generating an increase in head.
00:14
Pumps are generally used for collection from boreholes
00:17
and wells or distribution from a source of
00:19
water like a reservoir tank or contact tank
00:22
or for boosting pressure within a network.
00:25
The most common type of pump and water distribution is a centrifugal pump
00:29
where spinning impellers create rotational kinetic energy
00:32
that is transferred to the liquid.
00:35
Pumps can be characterized by their flow slash head curve.
00:39
Their mechanical or electrical power efficiency
00:41
along this curve and their rotations
00:43
per minute and power drive which can be fixed or varied.
00:48
Pumps can be configured with various complex control schemes but
00:52
typically pumps target a flow outlet pressure or reservoir level.
00:58
A pump curve shows the head a pump generates at a given flow rate.
01:02
Mechanical efficiency can also be included in which
01:05
case it is referred to as a triplet.
01:08
The speed of the pump's ac motor is relative to the power frequency supplied to it.
01:13
By reducing the frequency.
01:15
The pump generates less head at a given flow rate.
01:19
This can be used to make the pump operate
01:21
more efficiently across a wider range of demands.
01:25
These are known as variable speed pumps and
01:27
are not mechanically different from fixed speed pumps.
01:30
With the exception of their power supply.
