Suggested Specifications for Architects and Engineers Furnish and install where shown on plans, Fed-Flush Type VSAF-_____, duplex, vertical, submerged strainer basket type sewage ejector unit as manufactured by Federal Pump Corporation. Each pump to be rated at _____G.P.M. against a total dynamic head of _____feet. Pumps to have _____inch discharge and be constructed for basin _____feet deep. The unit shall be so designed that sewage entering the pit shall be carried to the strainer baskets installed in pump discharge lines. Solids will be retained in the baskets and liquids will continue thru the casing into the basin. The strainer shall have a cast iron housing and a stainless steel basket, removable from the top of the housing. Solids shall be flushed into the discharge line during the discharge cycle. A control valve shall prevent back-up into the house line during discharge cycles and permit cut-off of either pump. Overflow fitting shall allow liquid to flow directly into basin during discharge cycles. Pump shaft shall be large diameter carbon steel; impeller to be cast iron, non-clog type; thrust bearing enclosed in moisture-proof housing, mounted above the suspension plate. Suspension plate shall be cast iron; suspension column shall be constructed of cast iron sections, with integral rabbetted end flanges. Bronze intermediate guide bearings shall be furnished for every four feet of shaft length. Cast iron pump casing shall have pressed-fit bronze bearing. Lubrication of guide bearings shall be by means of alemite grease fittings on suspension plate and flexible grease lines. Casing shall have bolt-on discharge elbow forming lower expansion joint housing. Discharge pipe to terminate above the suspension plate in a cast iron 45° elbow and top expansion joint housing, with 125# ASA integral flange. Motors to be _____H.P., _____R.P.M., _____ph., _____cy., _____volts, vertical, open, drip proof, ball bearing. Furnish a pedestal mounted alternating float switch, with brass rod and copper float, to provide alternate cycles of operation, plus simultaneous operation when required. Furnish a pedestal mounted auxiliary float switch with brass rod and copper float, for emergency 2-pump operation. Float control equal to Federal Type FS-4. Furnish a compression tube type high water alarm actuating switch with adjustable sensing tube and integral alarm horn, equal to Federal Type FS-5. Furnish each motor with a magnetic line voltage starter providing overload and low voltage protection, in NEMA-1 wall mounting enclosure, having "Hand-Off-Automatic" selector switch and reset button. Furnish a cast iron (or steel) sewage basin, _____diameter by _____deep, having internal rust resistant coating. Inlet connection shall be as required by job conditions. Cover shall be steel with all required openings, including those for pumps, controls, alarm actuator, vent connection, and manhole. Manhole opening provided with cast iron cover. ALTERNATE FOR CONCRETE PIT (substitute the following paragraph for the above cast iron basin paragraph) Furnish a Federal PF-1 type angle iron pit frame for a concrete pit _____x _____x _____deep. Pit to be constructed by general contractor. Plumbing contractor shall furnish the pit frame together with a heavy steel pit cover having all required openings, including those for pumps, controls, alarm actuator, vent connection and manhole. Manhole opening provided with cast iron cover. Cover and frame to be treated with a corrosion resistant coating and to be of castight bolted construction. Note: Inlet adaptor for mounting FED-FLUSH fittings must be installed when concrete pit is poured. (Advise inlet size and pit wall thickness when ordering adaptor.)
SUGGESTED
SPECIFICATION FURNISH AND INSTALL AS SHOWN ON PLANS, A FEDERAL PUMP CORPORATION TYPE VSAF FED-FLUSH DUPLEX SUBMERGED SEWAGE-PUMP UNIT. PUMPS SHALL BE RATED AS SHOWN IN THE PUMP SCHEDULE. THE UNIT SHALL BE DESIGNED SO THAT SEWAGE ENTERING THE PIT SHALL FLOW THROUGH STAINLESS STEEL STRAINER BASKETS IN THE PUMP DISCHARGE PIPES. SOLIDS WILL BE RETAINED IN THE BASKETS AND THE LIQUID WILL CONTINUE THROUGH THE PUMP CASINGS INTO THE BASIN. SOLIDS WILL BE FLUSHED INTO THE DISCHARGE LINE DURING THE DISCHARGE CYCLE AND A CONTROL VALVE SHALL PREVENT BACKUP INTO THE HOUSE LINE. AN OVERFLOW FITTING SHALL ALLOW LIQUID TO FLOW DIRECTLY INTO THE BASIN DURING DISCHARGE CYCLES, IF NECESSARY. EACH PUMP SHALL HAVE A CAST IRON, NON-CLOG, BALANCED IMPELLER, CARBON STEEL SHAFT, THRUST BALL BEARING MOUNTED ABOVE THE SUSPENSION PLATE, BRONZE PUMP BEARING, A BRONZE INTERMEDIATE BEARING FOR EACH FOUR FEET OF UNSUPPORTED SHAFT LENGTH, A PVC GREASE LINE FOR EACH BEARING, CAST IRON SUSPENSION PLATE, CAST IRON LEG SECTIONS WITH INTEGRAL END FLANGES, A STEEL DISCHARGE PIPE WITH AN EXPANSION JOINT AT EACH END, AND A 45-DEGREE DISCHARGE ELBOW. EACH PUMP SHALL BE DRIVEN THROUGH A FLEXIBLE COUPLING BY A VERTICAL MOUNTED STANDARD NEMA FRAME MOTOR IN AN OPEN, DRIP-PROOF HOUSING, AS RATED IN THE PUMP SCHEDULE. 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. EACH SWITCH SHALL HAVE A COPPER FLOAT AND BRASS ROD WITH ADJUSTABLE STOPS. FURNISH A COMPRESSION TUBE TYPE HIGH WATER ALARM ACTUATOR AND A 4" 110V ALARM BELL. FURNISH A MAGNETIC STARTER FOR EACH MOTOR IN A NEMA-1 GENERAL PURPOSE ENCLOSURE WITH OVERLOAD PROTECTION ON EACH PHASE AND A HANDOFF-AUTOMATIC SELECTOR SWITCH IN THE COVER. FURNISH A CAST IRON SEWAGE BASIN OF THE SIZE SHOWN IN THE PUMP SCHEDULE. THE BASIN SHALL HAVE A GAS-TIGHT STEEL COVER WITH OPENINGS FOR THE PUMPS, CONTROLS, MANHOLE WITH COVER, AND VENT CONNECTION. THE BASIN AND COVER SHALL HAVE A CORROSION-RESISTANT COATING. PUMP SCHEDULE: PUMPS: __________ GPM PER PUMP __________ FT. TDH MOTORS: __________ HP, __________ RPM __________ PHASE, 60 CYCLES, __________ VOLTS CAST IRON BASIN: __________ IN. DIA. x __________ IN. DEEP *
* MINIMUM DEPTH FROM BASIN TOP TO INLET CENTERLINE IS 2'0" MINIMUM DEPTH FROM INLET CENTERLINE TO BASIN BOTTOM IS 3'6"
