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

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

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.

IFB 26-541 | 4-Inch Submersible Solids Handling Pump | Issue Date: 06/04/2026
6. Shaft Seal Arrangement
a. Pump(s) shall be provided with two separate tandem-mounted mechanical
seals to prevent the pumped liquid from entering the rotor/stator cavity
area to ensure reliability of operation. The upper and lower seals are
mounted to rotate in the same direction.
b. The lower mechanical seal mating surfaces are to be immersed in an oil
bath, sealing the pump volute chamber from the oil cavity. Oil in this cavity
shall also lubricate the upper mechanical seal faces. Seal faces of both
the upper and lower mechanical seals shall be held in contact by
independent polymeric elastomer bellows, which act as a spring
mechanism. Seals require neither maintenance nor adjustment but shall
be easily inspected and replaced. Pressure generated by the pump assists
in sealing the mating surfaces of the lower seal.
c. Component material for the upper seal shall consist of a composite
elastomer body, carbon steel snap ring, Buna-N O-ring, carbon rotating
face and ceramic stationary face. Lower seal component construction shall
include a composite elastomer body, stainless steel clamp and set screws,
Buna-N O-ring, silicon carbide rotating face and tungsten carbide
stationary face.
d. Two moisture detection probes shall be installed so that they will detect
moisture in either the seal or stator cavity measuring resistivity between
the probes. They shall be wired internally to the control cable connection
at the top of the motor. Float type devices located in the rotor/stator area
or single probe-to-ground moisture detectors measuring continuity are not
acceptable. O-ring sealed inspection plugs shall be provided in the
mechanical seal oil chamber for ease of inspection, draining and filling of
oil.
7. The pump shall rotate on a grease lubricated-for-life thrust bearing (oil
lubricated in 210 frame) and grease lubricated radial bearing (oil lubricated in
210 frame). Lower shaft bearings shall be locked in place to prevent shaft
movement and to take thrust loads.
8. Fits and Hardware
a. All machined bolts, nuts, and capscrews shall be 316L stainless steel and
be of the hex-head type and will not require the use of any special tools.
b. A heavy-duty 316L stainless steel lifting bail shall be included and be of
adequate strength to lift the entire pump and motor assembly.
9. Testing
a. A certified factory performance test shall be performed on each pumping
unit in accordance with Hydraulic Institute Standards, latest edition. Tests
shall be sufficient to determine the curves of head, input horsepower, and
efficiency relative to capacity from shutoff to 150% of design flow. A
minimum of six points, including shutoff, shall be taken for each test. At
least one point of the six shall be taken as near as possible to each
specified condition.
b. Results of the performance tests shall be certified by a Registered
Professional Engineer and submitted for approval before final shipment.
10. Pumps shall be manufactured by companies whose management system is
registered to ISO-9001:2000.
