\ GREAT POWER PUMP.
1T WILL SUPPLY FIVE MILLION GALLONS
A DAY.

THE MOTIVE POWER IS WATER. NOT STEAM AT
BANGOR, Mn-DETAI1s OF ITS OPERATION.
The Deane Steam Pump Company. Of Holyoka
Mass. has just delivered to the city Of Bangor.
Me-. the largest power pump ever made in the
United States. 1t has a capacity Of 100000
gallons in twenty four hours. and is largo
enough to supply the water wants OF a city hav-
ing 10000 inhabitants. In describing the giant
machine. Charles l.. Newcomb. the superintend-
ent Of the company said: "a power pump differs
from steam pump nasmuch II derives its
motive power from water electricity and not
from steam. and this class Of pump is usually
employed in billy parts Of the country, because
the water power may be utilized there to good
advantage and at diminished cost. In Michigan
and Wisconsin these pumps are as popular as in
some parts Of the East.
The Bangor pump is a duplex, and its capac-
ity Of 100000 gallons is attained when its
crank shaft is run at the rate Of seventeen reyo-
lutons to the minute, and against total head
Of 375 feet. The intake pipe is ~ inches in
diameter. and the discharge pipe is lG inches in
diameter. The power that operates the pump Is
received by way Of a large pinion shaft. which
is connected to a turbine water wheel, which ha3
a capacity OF 100 horse power. The water wheel
supplies the power through the large pinion
shaft to plnion which in turn connects with
a monster gear with inserted wooden teeth II
inches in diameter and 30-inch width Of face.
This large gear is secured to a crank shaft
which is held in bearings AZ inches in diam
eter and - inches long. OF these being placed
at each end Of the gear To the end Of the
crank shaft disks feet 6 inches in diametei
are secured. and into these fitted large steel
pins having diameter Of inches. These crank
pins were put in place by means Of hydraulic
pressure, and are secured in position by giant,
keys. The connecting rods are made OF ham,
mered wrought iron scrap. and to each end ot
these fitted bronze boxes, in which the crank
pin and crosshead pin run. The crosshead, in
turn, is connected to a large punger which IS
II inches in diameter
when this IOnderOus machine is set in mo-
tion d stream Of water is conveyed throuc/
5000 feet OF lG-inch pipe at velocity OF 200
feet minute To speak Of this pump in terms
that will appeal 10 those who are not experts in
hydraulics. it may be said that If connected to a
fire system it will throw twenty large fire
streams loo feet high or equal ten Of the lars-
est fire engines working at their maximum ca
pacity 1t will throw 400 gallons OF water
every minute 100 feet high.
The pump was made. from drawings to final
finishing. at the works Of the company, and
when 1t was ready for delivery 1t weighed 2OO.-
900 pounds and took eight cars to transport it
to its destination. II will be erected in space
80 feet long and 40 feet wide"
A similar pump with a capacity Of 100000
gallons. was built by the same company in 1894
for Lewiston. Me. II has been in successful
operation ever since its erection and its success
leads the builders 70 look for similar good results
at Bangor.
