Characteristics for Diamond Creek Submersible Pump/Motor Assembly

General Requirements:

• Supply two (2) complete submersible pump and motor assemblies. Components must be mated together and be delivered ready to install.

• The complete assembly shall contain the following: one pump, one motor, one interconnector to mate pump and motor housing together, one adapter plate to mate motor housing to interconnector, one shaft coupler to mate pump and motor shafts, one stainless steel interconnector intake screen, and motor leads of at least 50 ft length.

• Pump/Motor assembly must be shipped with at least -30 degree anti-freeze installed in motor to permit storage in an unheated location prior to installation

• Pump/Motor assembly must be shipped secured to an appropriate pallet

• All components listed shall be supplied as brand name or equal; VENDORS MUST PROVIDE

MATERIAL SPECIFICATIONS, PERFORMANCE SPECIFICATIONS, AND

DIMENSIONED DRAWINGS WITH QUOTATION FOR EVALUATION PURPOSES.

Pump Assembly:

• Peerless 18HH complete single stage pump

• Pumping capacity of 5000 gpm at an elevation of 5412.00 feet and maximum head of 65 feet

• Pump shall contain a 7 vane, impeller material ASTM B148 OR ASTM B548 per original pump specifications. Note: The vendor may propose an alternate impeller design providing that all design dimensions and material specifications are provided to the government for evaluation.

• Pump shall contain an impeller shaft with a diameter of 2 3/16ths inch and be made of 416 stainless steel with a ½ inch square keyway

• Pump must contain a stationary C93200 bronze upthrust bearing to absorb momentary up thrust upon start up

• Pump mounting bolt pattern shall be a standard 14” schedule 30S pipe flange

• Note: Original equipment included sand lugs cast into the bowl to reduce wear, erosion, maintain efficiency and lengthen pump life. The vendor may propose a bowl design without sand lugs providing that all design dimensions and material specifications are provided to the government for evaluation.

Submersible Motor Assembly:

• Hitachi Submersible Motor

• Type VT1 (The type of indicator is manufacturer- specific info, reference Hitachi)

• Form KK (The form indicator is manufacturer-specific info, reference Hitachi)

• 10 inch outside diameter motor housing

• Motor shaft size 1.937” (1 15/16ths) with ½ square keyway

• 125 horsepower

• 3 phase

• 4 pole

• 460 volts

• 60Hz

• 175 full load amps

• 1750 rpm

• Service Factor 1.15

Diamond Creek Pump - Salient Characteristics dra ft

• Locked rotor code C or D

• Design C

• Time rating – continuous duty

• Full load efficiency at least 85.8

• Full load power factor at least 78.6

• Type of enclosure – water filled (shipped with -30 degrees anti-freeze in it)

• 10,000 pound capacity thrust bearing mounted on the lower end of the motor

• 50 feet of at least 2/0 submersible cable pigtailed to assembly

• Motor shell and shaft must be stainless steel to withstand water pH between 6.5 – 8 and sand content up to 50 ppm

• Single mechanical shaft seal

• Motor must function at ± 10% of rated voltage (460v) and frequency (60Hz)

• Due to the fact the initial hookup phase rotation may be wrong, the thrust bearing must be un-affected by rotational backspin

Submersible Splice Kit:

• Two (2) submersible splice kits, capable of splicing all electrical leads from the motor

Pump to Motor Interconnector

• Interconnector must be capable of connecting pump housing to motor housing

• Use of an adapter plate is acceptable

• One stainless steel interconnector intake screen, attached to interconnector

• Pump section interconnector must contain an extra-long C93200 bronze bearing with a minimum 5:1 length to shaft diameter ratio to prevent radial thrust loads from being transmitted to the motor

• Pump suction interconnector must contain a C92700 bronze sand collar over the bronze interconnector bearing to prevent abrasives from entering the bearing

Motor Coupler

• 416 stainless steel motor coupler (3.5” O.D X 6.00” L) to adapt motor shaft to pump shaft

• ½ inch square keyways

DELIVERY DATE:

The delivery date is 180 days or less from the date of award.
