201D Suggested Specifications for Architects and Engineers Furnish and install as shown on plans a duplex VSP-_____ , vertical submerged sump pump unit as manufactured by Federal Pump Corporation. Each pump shall be rated _____G.P.M. at _____feet Total Dynamic Head, shall have a _____inch discharge and be built for a pit or basin _____deep. Shafts to be carbon steel, turned and ground; impellers to be bronze (or cast iron), hydraulically and dynamically balanced. Thrust ball bearing shall be fully enclosed in a dust- and moisture-proof housing mounted above the suspension plate. Pump casing shall include a renewable sleeve bearing with required means of lubrication. Renewable intermediate guide bearings shall be furnished where pit depth requires. Impellers shall be sized for the exact capacity and head specified and shall be fully non-overloading at the H.P. specified throughout the entire range of operation. Motors shall be _____H.P., _____phase, _____cycle, _____volts, _____R.P.M. open, drip-proof ball bearing type, flexibly coupled to pumps. Furnish a pedestal mounted alternating float switch to alternate the operation of the pumps and provide simultaneous operation when required. Furnish a pedestal mounted auxiliary float switch to turn on both pumps if the alternating float switch is inoperative. The float switches shall have copper floats, brass rods, adjustable stops, galvanized rod guides and shall be equal to Federal Type FS-4. Furnish a compression tube type high water alarm with integral horn, equal to Federal Type FS-5. Furnish for each motor a magnetic line voltage starter in wall-mounting general purpose enclosure providing overload and low voltage protection and with a Hand-Off-Automatic selector switch in the cover. Furnish a welded angle iron pit frame and heavy steel cover equal to Federal Type PF-1 for a concrete pit _____x_____x_____ deep. The cover and frame are to be treated with a corrosion resistant coating. Cover shall have required openings for pumps, controls, manhole and vent connection. ALTERNATE FOR BASIN: Furnish a cast iron (or fiberglass or steel) sump basin ___ diameter x ___ deep with an inlet connection as determined by job conditions. The basin shall have a steel cover with required openings for pumps, controls, manhole and vent connection and shall be treated with a corrosion resistant coating.
