Deep-WeII Pumps.
Deep-well pumps are heavier and stronger than
those described above. They may be of the lift or
force type and the standard or working head Is
always directly over the well. The cylinder
should be near (within Is feet) or else below
water level which pumping and drought may Gre

Pumping by means of compressed air is very
old, but the systems used prior to 1909 required
the air supply to be turned on or shut OF accord
ing to whether or not the water was needed
Based on patent granted in that year q tWo-
cylinder airdisplacement pump submerged In the
wafer supply and controlled by the opening and
, closing Of the faucet was devised. The essen
ia! parts Of installation, besides such pump
are an air compressor, storage tank, engine or mo-
tor-with air and water pipes. and minor attach
ments. The pump operates only when water is
used. starting whenever faucet is opened and
continuing until all faucets are closed.
The chief advantage of air-dispacement pumps
is that water may be taken from ordinary defth
lateral distance. from several sources with
power outfit and delivered direct from the
well to the faucet. The power plant may he
located wherever convenient and as many pu.nus
may be used as there are sources of water. Both
hard and soft water may be delivered by using
two pumps and the necessary piping systems
Air-displacement pumps not adapted at pres
ent to lifts much over 125 feet or to wells :ess
than three inches in diameter, nor can they be
used where more water is required than the
well can supply within specified period. Air
pipes and air-displaccment pumps must be tight
and remain tight in service, and working parts
must be kept in good order.
Horsepower Needed.
Water may be raised by hand, windmill nv
draunc rams, steam, hot air, gas, internal cCm-
bustion engines. electric motors. Hand power
is unsuited to large supplies high lifts. Wind
mills are probably the most familiar type of me-
chanical power used, and often arranged to
start and stop automatically Gasoline and oil
engines are well adapted to farm pumping AMI
may be equipped to stop at any desired pressure
in supply tank. The of electricity for
pumping is increasing. The method is clean.
quiet, and convenient, and starting stopping a
teal wherever transmission lines are sufficiently
near.
The theoretical horsepower needed to raise
water Is found by multiplying the gallons pumped
in minute by the total lift. in feet incIuC ng
friction in both suction and discharge pipes. and
then dividing the product by 1000. The horse
power, computed, should be multiplied by from
two to four to overcome losses in pumping and
still allow for reserve of power. Ordinarily
one to two horsepower engines suficien: for
farm pumps. but it is always safest to determine
this point by computation.
An advantage to be derived from the weT1-fn-
stalled farm water system often overlooked is the
benefit it affords in the way of fire prevention
With relatively small expenditure, fixtures can be
added to pipe system, which give ready access
to the water supply for fighting flames. IN al
