Water Lifted By Compressed Air
For Municipal, Manufacturing, Irrigation or Other Water Supply

Selection of an Air Compressor. The type of compressor best suited depends upon the conditions existing in the customer’s power plant. If there is available sufficient engine power which will always be running whenever it is neces- sary to operate the Air Lift, a belt-driven compressor can usually be installed most economically, especially for small and moderate quantities of water in manufacturing establishments where the engine in use is a Corliss or other highly economical type. But it does not pay to run a large engine especially to drive a small com- pressor for more than a very short time. If there is available cheap electric current and no spare steam or belt power we can furnish compressors built to be driven direct by an electric motor, the motor to be furnished either by our customer or by ourselves. Sometimes a water power may be used to operate either a belt-driven or direct-connected compressor. We can furnish ma- chines complete, connected to Pelton or turbine water wheels. For medium and large quantités of water it is usually best to put in complete steam-driven compressors having either Meyer cut-off or Corliss steam cylinders, often compounded, and in many cases run condensing, using in the condenser the water pumped by the com- pressor before passing it to its final uses. The size of the compressor depends on the quantity of water to be pumped and upon the lift and not upon the number of wells. The design of the steam end depends mostly upon the steam press- ure available and as to whether a condenser is to be used. The design of the air end and its size relative to the steam end depends upon the vertical lift to be met and the depth of submergence that will be available; in other words, upon the air pressure that will be required to give the best results. These points are all best left to us to determine, as our wide expe- rience has fitted us to make the best selection for the interests of our customers.
