4 SPECIFICATIONS
The City of Hot Springs, Arkansas, on behalf of the Engineering and Utilities Department, is accepting bids to
purchase one (1) Wet Well Mounted Sewer Pump Station with two (2) non-clog series pump sets for the Hot Springs
3 Lift Station located at 2344 Higdon Ferry Road. The Vendor shall furnish and setup a factory-built automatic
pumping station (all appurtenances, controls, etc.) manufactured by Smith and Loveless, Inc., Lenexa, Kansas, or
approved equivalent. The station shall be completed with all needed equipment, factory-installed on a welded steel
base with a fiberglass cover. Bidders can find the Smith and Loveless Drawing in the Attachment Tab. The following
specifications describe the minimum requirements.
The principal items of equipment shall include four vertical, close-coupled, motor-driven, vacuum primed, non-clog
pumps, valves, internal piping, central control panel with circuit breakers, motor starters, and automatic pumping
level controls, heater, ventilating blower, priming pumps with WaveStart™ pump prime detection system and
appurtenances, and all internal wiring.
The equipment bid shall be of a new, current design production model and available to the commercial market. The
bid shall include one (1) copy of the standard items manufacturer’s published specifications furnished unless
otherwise noted and warranty. The City reserves the right to review the manufacturer’s specifications and to choose
the materials deemed to be in the City’s best interest. Any and all freight charges, demurrage, fuel surcharges, or
special handing charges shall be price separately. Order will be accompanied by a City Purchase Order. The
equipment shall comply with all state and federal safety requirements. Any deviations to these specifications shall
be explained. The City of Hot Springs reserves the right to award within the budget available for the project.
1. Operating Conditions
Two (2) pumps running in parallel shall be capable of delivering 650 GPM of raw water or wastewater against
a total dynamic head of 150 ft. The minimum acceptable pump efficiency at this condition shall be 77 %. Due
to the energy conservation requirements, the minimum efficiency will be enforced. The maximum allowable
speed shall be 1,760 RPM. The minimum rated horsepower of each pump motor shall be 20 HP. The actual
static suction lift, measured from the station baseplate to the “off” level in the wet well, shall be 20 ft minimum.
The pump station utilizes Smith & Loveless Model 4C3B Pumps.
All openings and passages shall be large enough to permit the passage of a sphere 3'' in diameter.
The pump motors shall not be overloaded beyond their nameplate rating, at the design conditions, nor at any
head in their respective operating range.
2. Construction
The station shall be constructed in one (1) complete factory-built assembly. It shall be sized to rest on the top
of the wet well as detailed in the attached drawings. The supporting floor plate shall be a minimum of 1” thick
steel with reinforcing, as required, to prevent deflection, and ensure rigid support.
The pump station shall be enclosed by a two-piece hinged fiberglass cover. The cover shall have a suitable
drip-lip around the edge and shall be provided with means to allow the pump chamber to be locked with
padlocks.
Each cover shall be attached with a multi-segment stainless steel hinge, constructed of seven (7) gauge
(minimum) Type 304 stainless steel with a 3/8” diameter stainless steel pin and supporting at least 75% of the
width of one (1) end. Stainless steel bolts with tamperproof heads and a full width 3/8” thick anodized
aluminum backing plate shall anchor the hinge to the fiberglass cover.
Dual high-pressure gas struts shall be provided to counteract the dead weight of the cover assembly and limit
the maximum lifting force required for opening to less than 20 lbs. The cover shall be self-latching upon
opening, with a manually operated release for closing. Duplex heavy gauge safety chains shall be provided to
prevent over-extension. All hardware and components of the cover assembly that are exposed to the weather
shall be constructed of corrosion-resistant materials.

HS-24-029
A 1/4” thick sliding aluminum manway cover located exterior to the fiberglass pump chamber shall be
provided, complete with padlocking provisions. The manway shall be an integral part of the station floor plate
and provide access to the wet well.
The pump volutes and discharge piping shall be mounted in relation to the floor plate as detailed on the
drawings. Enclosures utilized to house the valve train and/or controls, which are defined under OSHA Article
29CFR, Part 1910 as a Confined Space, shall not be acceptable.
A stanchion with a lifting arm shall be provided to lift each pump. The lifting arm shall have a hook over the
center of the motor to support a hoist (provided by others) for the removal of the motors, impellers, and
pumps from the station.
3. Welding
All steel structural members shall be joined by electric arc welding with welds of adequate section for the joint
involved.
4. Protection Against Corrosion
All structural steel and cast iron surfaces shall be factory blasted with steel grit in an environmentally
controlled booth, to remove rust, mill scale, weld slag, etc. All weld spatter and surface roughness shall be
removed by grinding. Surface preparation and cleanliness shall comply with SSPC-SP6 specifications. The
surface profile shall be 2.0 mils (0.05 mm). Sandblasting is specifically prohibited. After blast cleaning, all
surface contaminants, such as grease or oil, shall be removed before coating.
Immediately following cleaning, a single 6 mil (0.15 mm) minimum dry film thickness coating of VERSAPOX®, a
self-priming Cycloaliphatic Amine Epoxy, shall be factory applied to the cleaned components.
After curing, a 2.5 mil (0.06 mm) minimum DFT top coating of semi-gloss XTRATHANE™, a moisture-cured
Aliphatic Polyurethane protective finish, for abrasion resistance and weather protection, shall be applied to
the exterior areas, including the pumps and piping and the top and sides of the base, if carbon steel. These
coatings shall be as formulated by Smith and Loveless specifically for this type of application and service.
Stainless steel, aluminum, and other corrosion-resistant surfaces shall not be coated. Carbon steel surfaces
not otherwise protected shall be coated with a suitable non-hardening rust-preventative compound. Auxiliary
components shall be furnished with the original manufacturer’s coating.
Finish coating shall be accomplished prior to shipment of the equipment from the factory and shall comply
fully with the intent of these specifications. A touch-up kit shall be provided by the pump station manufacturer
for the repair of any mars or scratches occurring during shipping and installation. This kit shall contain
detailed instructions for use.
5. Main Pumps
The pumps shall be 4” vertical, centrifugal non-clog type of heavy cast-iron construction, specially designed
for the use of mechanical seals, and vacuum priming. In order to minimize seal wear caused by linear
movement of the shaft, the shaft bearing nearest the pump impeller shall be locked in place, so that end play
is limited to the clearance within the bearing. To minimize seal wear resulting from shaft deflection caused by
the radial thrust of the pump, the shaft from the top of the impeller to the lower bearing supporting the
impeller shall have a minimum diameter of 1-7/8” for motor frame sizes two hundred thirteen (213) through
two hundred eighty-six (286) , 2-1/8” for motor frame sizes three hundred twenty-four (324) and three
hundred twenty-six (326), and 3” for frame three hundred sixty-four (364) and larger. The dimension from the
lowest bearing to the top of the impeller shall not exceed 6”.
The oversized shaft incorporating oversized bearings and heavier bearing frame construction provides for
extended mechanical seal, bearing, and overall pump/motor life.
Since the larger shaft with the specified minimum overhang is the key to heavier, more rigid construction
throughout, no deviation from the specified shaft diameter or tolerances will be allowed.
The bearing nearest the impeller shall be designed for the combined thrust and radial load. The upper
bearing shall be free to move in a linear direction with the thermal expansion of the shaft and shall carry only
radial loads.
