Features
RECEIVING TANK: Heavy steel construction, mounted on steel saddles 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 makeup 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 wall-mounting enclosures. Units are available with 1750 R.P.M. or 3450 R.P.M. motors (see Engineering Selection Table).
UNITS: Unit is factory assembled. 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 List
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 boiled cover for clean-out and inspection.
DRAIN VALVE: Tank drain connection can be fitted and bronze drain valve.
EXTERNAL FLOAT CHAMBER MAKEUP VALVE: Mounted on end of receiver with 3-valve by-pass piping to permit manual an 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 funished 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 the 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: Pump discharge pressure gauge available.
NON-STANDARD MOTOR ENCLOSURES: Standard enclosures are drip-proof. Totally enclosed and explosion-proof enclosures are available.
TRANSFER SWITCHES: To alternate pump operation of transfer pump-boiler relationship in multiple-boiler installations.
CONTROL PANELS: Control components can be mounted on factory-wired wall-mounting 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, water-proof or explosion-proof enclosures for starters; combination magnetic starters and disconnect switches, plus combination magnetic starters and circuit breakers.
LARGER UNITS: For ratings in excess of 1000 Boiler H.P. and discharge pressures up to 125 psi, consult Factory or nearest Federal Pump representative.
STRAINER: Fitted to the return inlet connection of receiver.
CONDENSATION RETURN UNITS: BFV units can be furnished as condensation return units by substituting a float switch in the receiver to operate each pump and removing the makeup water valve.
SHUT-OFF VALVE FOR PUMP SUCTION: Units can be furnished with butterfly shut-off valve for each pump suction connection.
