1. GENERAL

1.1 Purpose

The intent of this specification is to define chemical/industrial type continuous duty centrifugal pumps for use in the F37 Pump Room for the Proton Improvement Plan II (PIP- II) Low Conductivity Water (LCW) system.

1.2 Application

The LCW system provides cooling water circulated via a closed loop where the temperatures range from 60°F to 120°F. The LCW system relies on these pumps to operate continuously. The centrifugal pumps described in this specification must be designed for reliable service life with minimal maintenance and low operation costs.

1.3 Design

The pumps for this project shall conform to the standard requirements of ASME/ANSI B73.1M [Ref. 7.1]. The pumps shall be axial end suction, single stage, horizontal axis, top centerline discharge, flexible coupled, back pullout, foot mounted type. All metal components having wetting surfaces shall utilize stainless steel as the material of construction.

1.4 Manufacturer and Model

Manufacturer: Flowserve Model #2K3x2-10ARV M3 ST

2. DESIGN CONDITIONS AND SIZING REQUIREMENTS

2.1 Fluid Service

The fluid service is clean filtered water (LCW) with a nominal temperature of 82°F (60°F min., 120°F max.).

2.2 Configuration

The pumping system is designed to have two identical (2) horizontal axis single stage centrifugal pumps operating in parallel, with one of the pumps in operation and the second pump in standby.

2.3 Pump Performance

• Rated operating point capacity should be a total developed head of 250ft at 400 gpm per pump

• Best efficiency must be greater than 65%

• Best efficiency point (BEP) flow must be such that the rated operating point (250 ft at 400 gpm) is between 80% and 100% BEP flow (80% BEP flow < rated operating point < 100% BEP flow)

• Net positive suction head required (NPSHR) should not be greater than 30 feet

• Head rise to shut off must be at least 10% of the head at rated capacity (due to parallel pump configuration)

• Minimum recommended flow less than 60 GPM

2.4 Motor Capacity

The motor should be sized to cover the full operating range of the rated impeller from shutoff to the end-of-curve without the use of a service factor. The end-of-curve power is defined as 120% BEP flow. Service factor on pump shall be 1.15.

3. PUMP CONSTRUCTION

3.1 General

All wetted parts must be type 316 stainless steel (D4/CF8M) and permanently marked with the material of construction. A nameplate shall be securely attached at a readily visible location on the pump and meet the ANSI requirements [p. 13, Ref. 7.1].

3.2 Casing

• The pump casing shall be designed to meet the requirements of ASME/ANSI B73.1M

[p. 1-6, Ref. 7.1]

• Castings shall be sound and generally free from porosity, hot tears, shrink holes, blow holes, cracks, scale, blisters, and similar injurious defects

• Casing shall have a bottom drain boss drilled, tapped, and plugged

• Suction and discharge neck shall be drilled and tapped with NPT connections for pressure gauges

• Casing shall incorporate integral mounting feet for support and be capable of accepting suction and discharge nozzle loading

• Rotational arrows shall be cast or securely attached to the pump

3.3 Impeller

• Impeller should be spin balanced to ISO 1940 Grade 6.3 criteria [Ref. 7.5].

• Impeller: 8.56” Dia.

3.4 Shaft

• The shaft should be solid with the deflection limited to a maximum of 0.002" at the face of the mechanical seal when subjected to the maximum dynamic hydraulic loads in the range of operations from shutoff to 120% BEP.

• To be furnished with grounded bearing

3.5 Bearings

• Anti-friction bearings must include an inboard radial bearing and an outboard double thrust bearing designed for minimum L10 life of 17,500 hours at maximum load

• Bearing shall be selected in accordance with ANSI/ABMA-9 [Ref. 7.3] and ANSI/ABMA- 11 [Ref. 7.4] load ratings and fatigue life for ball and roller bearings

• Lubrication method shall be oil bath

• Oil level within the bearing frame shall be monitored by sight glass Grounded bearings

3.6 Seals

The impeller shaft shall be fitted with a mechanical seal design for clean water with 316 stainless steel metal parts and viton O-rings. Crane, Chesterton, and Flowserve type of seals or equivalent are acceptable.

3.7 Coupling

The coupling shall be a flexible spacer type to permit disassembly and inspection without disturbing the case piping or driver.

3.8 Baseplate

Materials of construction shall be of formed steel, cast steel, or cast iron and conform to ASME/ANSI B73.1M [p. 4, Ref. 7.1] dimensional requirements. The baseplate shall have an opening that allows for the introduction of grout material to fix the assembly once the leveling nuts have been set.

3.9 Nozzles

• Openings for nozzles and other pressure-casing connections shall be standard nominal pipe sizes (NPS). Nozzles of 3-½, 5, 7, or 9 NPS shall not be used.

Suction: 8”, Discharge: 6”,

• Suction and discharge nozzle shall be 150# flanged and of equal rating

• Flanges shall conform to the requirements of ASME B16.5 [Ref. 7.6].

4. MOTOR SPECIFICATIONS

4.1 Operating Range

The motors furnished for these pumps shall be designed such that they will not overload for any portion of the operating region (i.e., shutoff to 120% BEP) without the use of a service factor.

4.2 Electrical Specifications

• TEFC (i.e., Totally Enclosed Fan Cooled) NEMA Premium [Ref. 7.2] efficiency type electric motors with a 1.15 service factor and Variable Frequency Drive ready, are to be used. 1800 RPM.

• Supply power must be 3 phase, 480 volt, and 60 Hz.

Motor horsepower not to exceed 50 BHP IEEE-841 motors

5. PERFORMANCE TEST REQUIREMENTS

Each of the pumps supplied must have performance test prior to shipping. A simple schematic showing the test setup shall be included. Plots of an adequate number of data points to show the hydraulic range of each pump shall be employed. Serial numbered characteristic curves and tabular data sheets must accompany each pump upon delivery.

The bid package must include the following:

• Pressure, discharge and suction, PSI

• Volumetric flow, GPM

• Net positive suction head required, feet of liquid

• Pump efficiency, %

• Brake Horsepower

If there is a charge for Fermilab personnel to be present at the performance testing include it in a separator quote.

6. INFORMATION REQUIRED WITH PROPOSAL

For a response to this request for proposal to be considered, it shall include the following:

• Pump curve showing Head, NPSHR, Brake Horsepower, and Efficiency versus volumetric flow

• Drawings showing the overall dimensions and the inlet/outlet connections

• Listing for the gross weight of the mounted pump and motor assembly

• Seal manufacturer and specifications

• Performance data sheet for the motor
