Horizontal Centrifugal
(For Clear Liquids)
Single-Stage
Multi-Stage
Horizontal Centrifugal- Pumps are gener ally used for water supply, either with overhead tanks or directly into mains as boosters. They are also used for various other services, such as boiler feeding, hot water circulation, filter swimming pool circulation. They are truly general-
purpose pumps. The double-suction single-stage pumps
embody up-to-date hydraulic develop ments with exceedingly high efficiencies. Their mechanical design is unusually
rugged, so that they are fitted for con tinuous service. Specifications-are given
in Bulletin. No. 408. The high-pressure multistage horizontal
split-case pumps have one-piece bronze diaphragms which eliminate leakage be tween stages. A volute or spiral in every stage results in high-pump efficiency with
out the use of diffusion vanes. The thrust is eliminated with a hydraulic balancing device. See Bulletin No. 414 for'specifica
tions.

Non-Clogging Centrifugal Pumps
(For Pulpy Liquids)
Made in all sizes and capacities, both horizontal and vertical, for
pumping raw sewage, industrial wastes, paper pulp, food pulps,
etc. They are extensively used for ejection of sub-basement
drainage from buildings, in municipal sewage lift stations, and in
place of conveyors in industrial plants.
In addition to the pumps, we are in a position to furnish com
plete sewage pumping apparatus consisting of tanks, valves,
fittings, piping, electric motors, automatic control, etc., all
factory assembled and ready for erection. Our engineering
department is in an excellent position to assist in the layout of
such equipments,
whether for buildings
or municipalities.
Economy non
clogging pumps have
several important
patented features
which make for longer
life, lower main-
tainance cost. Write
