Suggested Specifications for Architects and Engineers Furnish and install where indicated on plans, a Type BFC Simplex (or Duplex; Triplex; Quadruplex) Boiler Feed Unit, as manufactured by Federal Pump Corp., Unit No. BFC-_____ sized to provide feed water to _____boiler(s), (each) developing _____boiler H.P. (Each) pump shall deliver _____G.P.M. at a discharge pressure of _____PSIG at the pump(s). Unit shall be factory assembled by the pump manufacturer, including receiver and accessories plus pump(s) and motor(s) all mounted on a single steel base with pump suction piping complete. Pump(s) shall be close-coupled, end-suction, bronze-fitted, centrifugal type with balanced and enclosed impeller, leakless mechanical shaft seal and bronze shaft sleeve; driven by _____H. P., _____phase, _____cycles, _____volts, _____R.P.M. ball bearing, drip-proof (or totally enclosed; explosion-proof) motor(s). Single phase motors in fractional H.P. frame sizes shall have built-in thermal overload protection. Single phase motors in integral H.P. frame sizes and all three phase motors shall be provided with across-the-line type manual-reset magnetic starters in NEMA-1 general purpose (or NEMA-4 Water-tight; NEMA-7 Explosion-proof) wall-mounting enclosure(s). Receiver shall be of heavy steel construction, with anti-corrosion interior coating, gauge glass, thermometer, and connections for return, vent and drain. Makeup water valve, flange-mounted on tank head, shall be of all-bronze construction, float operated with makeup water strainer. Receiving tank capacity shall be _____gallons. Furnish and install on (each) boiler a boiler water level controller to automatically operate the pump(s), with low-water cut-off and alarm switch, plus alarm bell. Controller shall be equal to McDonnell-Miller No. 150 (for boiler pressures up to 150 P.S.I.) or No. 94 (for boiler pressures up to 250 P.S.I.). (Controllers not usually furnished by Federal).
