Deep-We Pumps
Deep-well pumps are heavier and stronger than
those described above. They may be of the lift or
force type and the standard working head Is
always directly the WELL The cylinder

ing cylinder must be determined from the size,
depth and yielding power Of the we'll. the guam
tity of water required, and the available power.
Deep wells and hand Windmill outfits take
small cylinders.
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 off accord
ing to whether not the water was needed
Based a patent granted In that year, a two
cylinder ar-dsplacement pump submerged in the
water supply and controlled by the opening and
closing Of the faucet, was devised The essen

used, starting whenever faucet Is opened and
continuing until all faucets closed.
The chief advantage Of air-dsplacement pumps
is that water may be taken from ordinary depth
or lateral distance, from several sources with
one power outfit and delivered direct from che

must be kept In good order.
