SPECIFICATION
CASING. The casing is of the volute type and
is designed to produce smooth flow with
gradual changes in velocity. The interstage
passage is cast integral with the lower half of
the casing and is carefully formed to eliminate
losses. The casing is split on the horizontal
centerline with the suction and discharge nozzles in the lower half. Access to the interior
of the pump for the purpose of inspection and
repairs is obtained by removing the upper
half of the casing. This may be done without
disturbing the pipe connection or pump alignment. The joint between the casing halves is
sealed by an especially prepared gasket.
IMPELLERS. Two single suction enclosed type
impellers are placed opposed on the shaft.
This results in a hydraulically balanced pump.
The impellers are firmly secured to the shaft
with keys. One renewable bronze bushing
ring is used on each impeller and maintains a
close running fit preventing excessive leakage.
Interstage leakage is prevented by a stage
piece which is so designed as to give a long
close clearance with the impeller hubs.
SHAFT. The shaft is made of heat-treated steel.
It is ground to accurate dimensions and is
polished to a smooth surface. Cast bronze
shaft sleeves protect the shaft in the stuffing
boxes. The sleeves are secured by external
nuts and the impeller key is extended into the
hub of the sleeves.
BEARINGS. The shaft is supported by two ball
bearings, one located on each side of the pump.
The outboard bearing is of the deep groove
thrust type and is water jacketed.
STUFFING BOXES. The stuffing boxes are of
extra depth to prevent leakage. The glands
are made of bronze and are secured with
special swing bolts. A water seal gland is
placed in the low pressure box and is connected to the pump discharge to provide liquid
under discharge pressure to prevent air leakage.
BEDPLATE. The standard bedplate is of rigid
construction and is provided with a raised lip.
The top of the bedplate is sloped to drain off
any leakage from the pump. The bedplate is
provided with lugs for foundation bolts.
COUPLING. A flexible coupling of the rubber
bushing and pin type is supplied with each
direct-connected unit.
EQUIPMENT. Each pump is equipped with the
necessary special wrenches, water seal piping,
air and water cocks and grease cups.
A bulletin giving complete instructions for installing and operating is supplied with each
pump.
