7 Specifications A. General: Provide submersible dewatering pumps suitable for continuous duty operation underwater without loss of watertight integrity to a depth of 6 feet. If mounted on a guide rail system, design shall be such that the pump will be automatically connected to the discharge piping when lowered into place on the discharge connection. The pump shall be easily removable for inspection or service, requiring no bolts, nuts, or other fasteners to be disconnected, or the need for personnel to enter the wet well. The motor and pump shall be designed, manufactured, and assembled by the same manufacturer. B. Manufacturer: Ebara International Corporation C. Pump Characteristics: Pumps shall conform to the following requirements: Number of units Design flow (gpm) Design TDH (ft) Minimum shut off head (ft) RPM 6 Maximum HP Minimum efficiency at design (%) Minimum power factor at design (%) Voltage/HZ 8/V, 6V / 6 Phase D. Pump Construction: All major parts of the pumping unit(s) including casing, impeller, motor frame and discharge elbow shall be manufactured from gray cast iron, ASTM A-8 Class. Castings shall have smooth surfaces devoid of blow holes or other casting irregularities. Casing design shall be centerline discharge with a large radius on the cut water to prevent clogging. Units up to and including HP with /'' and '' discharge sizes shall be furnished with a female NPT connection. Units HP and above with '' and larger discharge ports shall be furnished with a discharge elbow and lb. flat face ANSI flange. All exposed bolts and nuts shall be stainless steel. All mating surfaces of major components shall be machined and fitted with NBR O-rings where watertight sealing is required. Machining and fitting shall be such that sealing is accomplished by automatic compression of O-rings in two planes and O-ring contact is made on four surfaces without the requirement of specific torque limits. Units shall be provided with a galvanized strainer to prevent solids larger than the design will allow from entering the pump. Internal and external surfaces are prepared to SSPC-VIS--6 thencoated with a zinc-rich epoxy primer. The external surfaces are then coated with an H.B. Tneme-Tar 6- coal tar epoxy. Impeller shall be multi-vane open design, direct connected to the motor shaft with a slip fit, key driven, and secured with an impeller nut. Units / to HP shall be furnished with a replaceable SS wear plate. Units HP and larger shall have impellers with back pump out vanes and rear shroud operating with a replaceable SS wear ring as well as a replaceable cast iron suction cover. Suction covers on all models shall be designed such that they may be adjusted to maintain working clearances and hydraulic efficiencies. Double mechanical seals operating in an oil bath shall be provided on all units. The oil filled seal chamber shall be designed to prevent over-filling and include an anti-vortexing vane to insure proper lubrication of both seal faces. For applications under F; lower face materials shall be silicon carbide, upper faces carbon vs ceramic, NBR elastomers, and SS hardware. Applications greater than F shall include silicon carbide face materials for both upper and -9 (t) 8 7 (f) rev. /

8 Specifications E. Motor Construction: The pump motor shall be an air filled induction type with a squirrel cage rotor, shell type design, built to NEMA MG-, Design B specifications. Stator windings shall be copper, insulated with moisture resistant Class F (Class H for DSHU / & HP models) insulation, rated for F. The stator shall be dipped and baked three times in Class F varnish and heat shrunk fitted into the stator housing. Rotor bars and short circuit rings shall be manufactured of cast aluminum. Motor shaft shall be one piece SS AISI material, rotating on two permanently lubricated ball bearings designed for a minimum B- life of 6, hours. Model DSU motors shall be designed for continuous duty pumping at a maximum sump temperature of F and capable of up to starts per hour. Model DSHU motors shall be designed for up to starts per hour continuous duty pumping at a maximum sump temperature of 8 F for / and HP units, and 76 F for to HP units. Motor service factor shall be.. Voltage and frequency tolerances shall be a maximum %/% respectively. Junction area shall include a terminal board for power connections eliminating the need for wire nuts. Motor protection shall be provided by an auto-cut device located directly over the windings to provide protection from single phasing, low voltage, phase imbalance, locked rotor, and no load or run dry conditions. Motor shall be nonoverloading over the entire performance curve and be able to operate at full load intermittently while unsubmerged without damage to the unit. Power cable jacket shall be manufactured of an oil resistant chloroprene rubber material, designed for submerged applications. Cable shall be watertight to a depth of a least 6'. Cable entry shall be composed of a one piece, vulcanized, three way mechanical sealing system with a thick molded shoulder with increasing cable diameters to resist fatigue from bending forces. The molded shoulder, acts as the primary and secondary sealing points. This system shall also prevent leakage into the motor housing due to capillary action through the insulation if the cable is damaged or cut. Units / to 7 / HP shall utilize a metallic plate to clamp the entry system to the motor housing. Strain relief on these sizes shall be accomplished by clamping and attaching the cable with chain to the motor housing. Units larger than 7 / HP shall utilize a cast iron cable housing which is bolted to the top of the motor housing causing a compression fit between the molded shoulder and the top of the motor. Strain relief protection shall be provided by clamping the cable to the cable housing. F. Guide Rail system: Design shall include two () SS schedule guide rails sized to mount directly to the quick discharge connector, QDC, at the floor of the wetwell and to a guide rail bracket at the top of the wetwell below the hatch opening, (refer to project drawings). Units below one () HP shall utilize a single angle iron rail in lieu of two () Guide pipes. Intermediate guide brackets shall be supplied for rail lengths over feet. Guide rails are not part of the pump package and shall be supplied by others. The QDC shall be manufactured of cast iron, A8 Class. It shall be designed to adequately support the guide rails, discharge piping, and pumping unit under both static and dynamic loading conditions with support legs that are suitable for anchoring it to the wetwell floor. The face of the inlet QDC flange shall be perpendicular to the floor of the wetwell. The pump design shall include an integral self-aligning sliding bracket. Sealing of the pumping unit to the QDC shall be accomplished by a single, linear, downward motion of the pump. The entire weight of the pump unit shall be guided to and wedged tightly against the inlet flange of the QDC, making metal to metal contact with the pump discharge forming a seal without the use of bolts, gaskets or O-rings. Lifting chain, either galvanized or stainless steel, suitable for removing and installing the pump unit shall be provided (t) 8 7 (f) rev. /
