Part 2. Products

2.01 Pumps

A. Manufacturers

1. Pump(s) shall be the product of Fairbanks Morse Pump or acceptable

equivalent.

2. Manufacturers shall have installations of like or similar applications with a

minimum of 5 years’ service for this pump size.

B. Design

1. Rotation

a. The pump will be clockwise rotation when viewed from the driver end

looking at the pump.

2. Impeller

a. Impeller shall be of the balanced non-clogging type matched to its constant

velocity equalizing pressure volute and be made of close-grained cast iron

conforming to ASTM A48 CL30. It shall be of one-piece construction,

single suction, enclosed (bladeless)(two-vane), radial flow design with

well-rounded leading vanes and then tapered toward the trailing edge for

a circular flow pattern to prevent the accumulation of solids and stringy

material.

b. The clearance between the impeller outside diameter and cutwater shall

be capable of passing a 2” sphere.

c. The impeller is to be balanced and secured to the shaft by means of a bolt,

washer, and key. The arrangement shall be such that the impeller cannot

be loosened from torque in either forward or reverse rotation.

d. Wiper vanes on the back impeller shroud are not allowed.

e. Impellers shall be trimmed to specifically meet the conditions of operation.

3. Volute/Casing

a. Volute is to be cast with extra thick walls made of close-grained cast iron

conforming to ASTM A48, Class 30. It is to be one-piece, constant velocity

equalizing pressure with smooth fluid passages large enough to pass any

size solid that can pass through the impeller.

b. The volute shall have an integral tapered suction inlet area to direct flow

to the impeller eye and have a centerline-flanged discharge. Volute

discharge shall be minimum 4” diameter as measured on the inside

diameter of the discharge flange opening.

c. A sliding bracket assembly shall be a part of the pumping unit constructed

so that when lowered to the discharge base/elbow, the knifing action of

the vertical metal-to-metal seal provides a self-cleaning, non-clogging,

non-sparking UL Listed explosion-proof assembly.

IFB 26-541 | 4-Inch Submersible Solids Handling Pump | Issue Date: 06/04/2026

4. Wear Rings

a. Wear rings shall be provided on both the impeller and fronthead so that

clearances can be maintained throughout the life of the rings and minimize

recirculation.

b. Impellers wear rings shall be of the axial- or face-type.

c. Fronthead wear rings shall be of the axial- or face-type.

d. Wear rings shall be attached to the impeller and fronthead using an

interference fit and Loctite.

e. Wear rings shall be stainless steel, with the impeller wear ring

approximately 50 Brinell softer than the fronthead wear ring.

f. Wear ring clearance adjustment shall be attained through impeller

adjustment shims.

5. Motor

a. Pump(s) shall be driven by completely sealed, electric submersible

squirrel cage induction motors with a maximum NEMA nameplate rating

of 25 HP, 1.15 service factor, 1760 RPM, 460 volts, 3-phase, 60 Hertz.

b. Submersible equipment shall be UL Listed for Class I, Division 1, Groups

C and D explosion-proof hazardous locations as defined by the National

Electric Code. All electrical parts shall be housed in an air-filled (or oil-filled

in 210 frame construction) cast iron, watertight enclosure which is sealed

using O-rings and rabbeted joints with extra-large overlaps.

c. The stator winding and lead shall be insulated with moisture-resistant

Class F insulation for continuous duty in 40 degree C ambient. The motor

shall be designed for continuous duty capable of ten (10) starts per hour.

Automatic reset, normally closed thermal overloads shall be imbedded in

the motor windings to provide overheating protection. Motor winding

thermostats must be connected to an electric controller per local and state

codes and the National Electric Code.

d. Motor shaft shall be one-piece, 416 stainless steel. Carbon steel shafts or

shaft sleeves are not acceptable. Rotor is to be dynamically balanced to

meet NEMA vibration limits; all external hardware is to be stainless steel.

e. Cable leads are to enter at the top of the motor and are to allow the cable-

to-motor connection to be accomplished in the field without soldering. All

power and control lead wires are to be double sealed as they enter the

motor in such a manner that cable-wicking will not occur. This sealing

system shall consist of a rubber grommet followed by epoxy that is high in

adhesive qualities and has a low coefficient of expansion. Each cable wire

is to have a small section of insulation removed to establish a window area

of bare wire and each wire is to be untwisted and surrounded by epoxy

potting material. A cable strain relief mechanism shall be an integral part

of this sealing system. Cable sealing system shall be capable of

withstanding an external pressure test of 1200 PSI as well as a cable

assembly pull test as required by Underwriters Laboratories. mSingular

grommet or other similar sealing systems are not acceptable. Motor shall

be supplied with 40 feet of multi-conductor type “SOW-A” or “W” power

cable and control cable. Cable sizing shall conform to NEC specifications

and be UL Listed.

f. Power and control leads shall be terminated on a sealed terminal board.

The terminal board and its bronze lugs shall be O-ring sealed.
