1½" Discharge Sump Pumps
Bulletin
203A

FEATURES
MOTOR:
Standard NEMA frame sizes. Ball bearings are factory sealed and do not require
field lubrication. Drip-proof motors are standard. Totally enclosed and
explosion-proof motors also available. Single phase (115/230v.) motors have
built-in thermal overload protection. Three phase (208/220/ 440v.) motors should
be provided with magnetic starters.
FLOAT SWITCH:
Double break type in steel enclosure, actuated by copper float with brass rod
and stops.
COUPLING:
Single-piece type with adjustable set screws.
HANGAR PIPE:
Rigid steel pipe support insures accurate alignment.
SUSPENSION PLATE:
14" Diameter steel suspension plate is standard on Fig. 3 units. Split type
cast iron adjusting collar is available for field adjustment of length of pump
extension below suspension plate.
DISCHARGE PIPE:
Included on Fig. 3 units only. Discharge size is 1½".
STAINLESS STEEL SHAFT:
Diameter sized to operate at maximum speed with minimum vibration and
deflection.
BEARINGS:
Bronze guide bearings at pump casing and at intervals along shaft to prevent
radial deflection. Intermediate bearings are grease lubricated. Lower bearing is
self-lubricating and suitable for pumping hot or cold water.
IMPELLER:
Single-piece bronze impeller, machined and balanced; held firmly by key and lock
nut. Open, non-clog type.
CASING:
Cast iron, with 1½" discharge opening.
STRAINER:
Strainers on Fig. 1 units are perforated brass, forming part of the pump stand.
Strainers on Fig. 3 units are large area cast iron, fastened to bottom of
casing.
COVERS AND BASINS:
Steel covers are available for round, square, or rectangular pits and can be
furnished with grouting frames if desired. Steel or cast iron basins of all
diameters and depths are also available. Covers are fabricated to suit Fig. 3
pump suspension plates and include vent connection and manhole. Basin inlet size
and location are determined by job conditions.
MATERIALS OF CONSTRUCTION:
Standard pumps are of bronze fitted construction. All-iron, all-bronze, or
stainless steel pumps are also available.
SINGLE AND DUPLEX UNITS:
Figure 3 pumps are available as single or duplex units.
Single unit includes one pump and motor, one float switch, one magnetic starter
(if required), and one pit cover or basin.
Duplex unit includes two pumps and motors, two float switches,* two magnetic
starters (if required), and one pit cover or basin.
*One alternating float switch can be furnished on duplex units, instead of the
two standard float switches, to alternate the operation of the two pumps, and to
provide two-pump simultaneous operation if one pump cannot handle the in-flow.
