Sullivan Standard Air Lift Pump and Umbrella Well Top, with casing flanges and
connections
of bronze, with an air passage, leading from the outside, ter-
minating in a perforated vertical tube below a Venturi or throat,
so that the air is broken up into small jets, insuring a perfect mixture,
or emulsion, of the air and water, and increasing the velocity in the
throat to produce an ejector effect. By having a large number of
holes in the mixing tube, a mixture containing more or less air,
depending upon the lift, is made automatically, without change in
the pump. An opening just below the mixing tube permits sand or
scale, lodging in the tube when pumping is stopped, to drop through
and not plug the perforations.
