CASING:
Close-grained cast iron, horizontally split thru center of shaft for simple
removal of entire rotating assembly without disturbing suction and discharge
pipe connections. Both sections are bored and faced in one machine setting to
insure perfect alignment. Standard pumps, viewed from the drive end, have
suction on the right; the reverse can be specified when pump is ordered.
IMPELLER:
Double suction design insures perfect hydraulic balance. Impeller is machined
from single piece bronze casting, balanced and cut to meet exact conditions of
service required.
WEARING RINGS:
Bronze wearing rings are easily replaced; insure minimum slippage and high
efficiency.
SHAFT:
Turned and ground to insure maximum power transmission with minimum vibration or
deflection.
SHAFT SLEEVES:
Cast bronze sleeves extend through stuffing box; easily replaced; protect the
shaft from corrosion and wear.
BEARINGS:
Nationally recognized manufacture. Heavy duty ball bearings; grease lubricated.
STUFFING BOXES:
Ample depth for maximum pump working pressures. Lantern ring water-seal
available if required. Glands are bronze split type for simple packing
adjustment (mechanical shaft seals are available if preferred).
COUPLING:
Flexible type; sized for maximum power transmission.
BEDPLATE:
Cast iron drip-rim type with drain tapping and grouting opening. Fabricated
steel bedplates are also available.
DRIVERS:
Electric motor drive is standard. Gasoline or diesel engine and steam turbine
drivers are also available for special applications.
Type SSC - Two Stage
CASING:
Close-grained cast iron, horizontally split through center of shaft. Both
sections are bored and faced in one machine setting to insure perfect alignment.
IMPELLERS:
Single piece cast bronze, balanced and cut to meet exact conditions of service
specified. Keyed and locked to shaft. The two impellers are mounted with opposed
suction openings to provide for perfect hydraulic balance, eliminating thrust on
the bearings.
WEARING RINGS:
Bronze wearing rings are easily replaced; insure minimum slippage and high
efficiency.
SHAFT:
Turned and ground to insure maximum power transmission with minimum vibration or
deflection.
SHAFT SLEEVES:
Cast bronze sleeves extend through stuffing box; easily replaced.
BEARINGS:
Nationally recognized manufacture. Heavy duty ball bearings; grease lubricated.
STUFFING BOX:
Ample depth for maximum pump working pressures. Lantern ring water-seal
available on first stage stuffing box if required.
GLANDS:
Bronze glands allow for quick and easy packing adjustment. Drip pockets and drip
tappings are provided.
COUPLING:
Flexible type; sized for maximum power transmission.
BEDPLATE:
Cast iron drip-rim type, with drain tapping and grouting openings. Fabricated
steel bedplates are also available.

Suggested Specifications for Architects and
Engineers
Furnish and install as shown on plans a Type SC (or SSC) horizontally split
case, single stage (or two-stage), centrifugal pump, Model __________, as
manufactured by Federal Pump Corporation. Pump shall have a capacity of
__________G.P.M. against a Total Dynamic Head of __________feet, and shall be
flexibly-coupled to a __________H.P., __________Phase, __________cycles,
__________volts, __________R.P.M. drip-proof motor. Casing shall be of extra
heavy cast iron, the upper half of which shall be removable without
disconnecting suction or discharge piping.
Impeller(s) shall be enclosed, single-piece, cast bronze, of the double
suction type, (single suction mounted back-to-back for two-stage pumps).
Pump shall have renewable wearing rings. Shaft shall be of high grade alloy
steel protected by renewable bronze sleeves. Inboard and outboard bearings shall
be mounted in dust and moisture-proof housings.
Pumps shall have deep stuffing boxes with adjustable glands (or mechanical
shaft seals, if preferred). Entire unit shall be mounted on common extra heavy
cast iron drip-rim bedplate.
