FEATURES
RECEIVING TANK:
Heavy steel construction, mounted on steel legs, and fitted
with thermometer and gauge glass.
MAKEUP
WATER VALVE:
All-bronze
float actuated valve, flange mounted in tank head, permits entry of makeup water, when
required, to replace system losses. Complete with strainer
on make-up water connection.
PUMP(S):
Close-coupled, bronze-fitted, centrifugal design,
with
leakless mechanical shaft seal.
MOTOR(S):
Drip-proof ball bearing type close-coupled to pump(s). Single phase motors in fractional H.P.
frame sizes have
built-in thermal overload protection. Single phase motors in integral H.P.
frame sizes, and all 3 phase motors, are furnished with magnetic starters in NEMA 1 general purpose
wallmounting
enclosures. Units are available with 1750 R.P.M. or 3450
R.P.M. motors (see Engineering Selection Table).
UNITS:
Unit is factory assembled on single steel base with pump suction piping complete. Simplex unit has one
receiving tank,
one makeup valve and one pump and motor. Duplex unit has one receiving tank, one makeup valve, and two
pumps and motors.
Triplex unit has one receiving tank, one makeup valve and three pumps and motors. Quadruplex unit
has one receiving
tank, one makeup valve and four pumps and motors.
OPERATION:
Boiler
feed pump(s) is controlled by a boiler water level controller mounted on the
boiler. These controllers are usually furnished with integral low water
cut-off and alarm switches. Boiler feed water is taken from the receiver, and
if condensate has been lost in the system, it is automatically replaced by the
makeup valve.
MODIFICATIONS
TO STANDARD UNITS
NON-STANDARD
TANK SIZES: Units can be furnished with tank capacities other than shown
in the selection table. Diameters and lengths of receivers can be modified where
required by space conditions. Return inlet height and location can be modified.
GALVANIZING
OF RECEIVER: Hot-dip galvanized inside and outside.
SPECIAL
RECEIVER COATINGS: Special interior and exterior coatings where job
conditions require extra corrosion resistance.
INTERIOR
TANK BAFFLES: Built into tank to prevent air or sludge from entering pump
suction.
SPECIAL
RECEIVER TAPPINGS: Special or additional tappings as required.
MANHOLE:
Manhole and bolted cover for clean-out and inspection.
DRAIN
VALVE: Tank drain connection can be fitted with bronze drain valve.
EXTERNAL
FLOAT CHAMBER MAKEUP VALVE: Mounted on end of receiver with 3-valve
by-pass piping to permit manual and automatic makeup water control. Has built-in
strainer.
SOLENOID
OPERATED MAKEUP VALVE: Furnished with reverse-acting float switch in
receiver to actuate the solenoid valve. Requires electric service for operation
and is furnished with makeup water strainer. Can be furnished with or without
air gap.
CORROSION
INHIBITOR BAR: Magnesium anode bar in the receiver to inhibit electrolytic
corrosion, with drip-hole to indicate when bar has been completely corroded and
requires replacement.
FEED
WATER HEATERS: Perforated brass steam injection pipe operated by
temperature regulating valve with sensor.
SPECIAL
THERMOMETER: Standard column type can be replaced by special thermometers
as specified.
PRESSURE
GAUGES: Pressure gauge available for each pump discharge.
NON-STANDARD
MOTOR ENCLOSURES: Standard enclosures are drip-proof. Totally enclosed and
explosion-proof enclosures are available.
TRANSFER
SWITCHES: To alternate pump operation or transfer pump-boiler relationship
in multiple-boiler installations.
CONTROL
PANELS: Control components can be mounted on factory-wired wallmounting
or floor-mounting panel, in lieu of individual wall-mounting enclosures.
NON-STANDARD
MOTOR CONTROLS: "Hand-off-Automatic" selector switch, pilot
light and control circuit transformer for motor starters; waterproof or
explosion-proof enclosures for starters; combination magnetic starters and
disconnect switches, plus combination magnetic starters and circuit breakers.
FLEXIBLY-COUPLED
PUMPS: Can be substituted for the standard close-coupled pumps.
LARGER
UNITS: For ratings in excess of 1000 Boiler H.P. and discharge pressures
up to 125 psi, consult ABC Electric Corp.
STRAINERS:
In pump suction lines or fitted to the return inlet connection of receiver.
CONDENSATION
RETURN UNITS: BFC Units can be furnished as condensation return units by
substituting a float switch in the receiver to operate each pump and removing
the make-up water valve.
SUCTION
GATE VALVE: Can be added in each pump suction line to isolate pump from
tank.
