are an air compressor storage tank engine or r,,n

used. starting whenever a faucet Is opened o,id
continuing until all faucets ARE closed
The chief advantage Of airdisplacenent nunrs
IS that water may be taken from ordinary darih
or lateral distance. or from several sources with
one power outfit and delivered direct from the
well to the faucet. The power plant may he

Air-displacement pumps are not adapted M nres

than three inches In diameter. nor can they be-
used where more water is required than the
well can supply within specified period Air

and remain tight In service and working pa-ts
must be kept In good order.
Horsepower Needed
