Whatever type of plant is purchas-
ed it pays well to install it in a stable
manner and to house it we'll A good
masonry or concrete foundation
should be firmly bolted to it. The
pump should also be firmly set so
there is no slipping or vibration when
it is in motion. The centrifugal pump
should have a suction pipe that is
absolutely air tight and unless the (
pump is Immersed there should be .
a good positive acting foot valve on
the bottom. The lower end of the I
suction pipe should be placed low
enough so that it will be well under
the surface at low water and a screen /
or trash rack should be provided 50
that all debris and fine material viii
be kept out of the foot valve and out
Of the pump. The suction and dis
charge pipe should be comparative
ly large and as free from elbows and
sharp turns as possible in order to
cut down the FRACTIONAL resistance
as low as possible Where the dis
charge pipe is long one it should
be hade extra large for the same
reason. 1t is not SO necessary, how
ever to have it absolutely air tight
as the suction pipe The mere loss
of water from a leaking discharge
pine is the only objection while if
the suction pipe leaks the efficiency
will be lowered and the amount of
power required will be increased, and
! if the leak is excessive the pump will
lose its printing and the plant will
have to be shut down until the pump
is reprinted. 1t is always well to viii
en- the lower end of the suction pine
for about two feet on the end max
ing it funnel shape as the water en-
ters more easily and the saving i'm
power is sometimes very material.
The suction and discharge pipes
should be of such size that the vel
ocity of the water in them will not
exceed 10 feet per second. Wherever
the velocity exceeds this the friction
increases to such an extent that there
{ is considerable loss in power.
Water cannot be drawn economical
ly by suction over % feet. 1t is best
to have the pump as close to the
water as possible for water can be
pushed cheaper than pulled. Keep
the stuffing box on the shaft we'll oil
ed and be sure you run the pump 1T
> the same speed that the maker in
, tended it should be run for the heal
: you are pumping against. By observ-
ing the above rules and using much
5 care and ordinary precaution much
y trouble can be averted.
= Irrigation water is frequently vast
r ed shamefully and it is very seldom
4 put to it's best use. One reason fol
r this is because it is cheap and plenti

that under most gravity canals wher'

P the pump can be shut down and th'
