B. Operation and Maintenance Manuals

The Contractor shall furnish the Owner with five (5) copies of operation and maintenance instructions for the equipment furnished under this specification.


A. Testing and Materials Only materials specified and approved shall be used in construction of the facility. All

components of the pump station shall be given an operations test of all equipment at the factory to check for excessive vibration, for leaks in all piping or seals, and for correct operation of the control system and all auxiliary equipment.


11307- 2

The pump suction and discharge lines shall be coupled to a reservoir and the pump shall recirculate water under simulated service connections.

B. Pump Warranty The pump shall be guaranteed to be free from defects in materials and workmanship for a

period of one year from the date of acceptance. 1.7 DELIVERY, STORAGE, AND HANDLING All equipment incorporated into construction of the facility shall be delivered, stored, and handled

in accordance with the recommendation of the manufacturer for each piece of equipment. 1.8 PROJECT SITE CONDITIONS The Contractor shall visit the site to become familiar with the site conditions. Contractor is

responsible for performing any testing he deems necessary to satisfy himself of site conditions. PART 2 PRODUCTS 2.1 MANUFACTURERS The lift station pumps shall be manufactured by Flygt or preapproved equal. 2.2 MATERIALS AND/OR EQUIPMENT A. Wet well - Reinforced concrete pipe meeting ASTM C478, rubber gasket joints, with inside

diameter and depth as shown on the plans. The interior shall be coated with a 10 mil thickness of coal tar epoxy, Pittsburgh two (2) part "Coal Cat", component "A" is No. 97-640 and component "B" is No. 97-641; Tnemec two (2) part "Tneme-Tar", No. 46-413; or approved equal.

B. Pumps and Motor - Two submersible grinder pumps shall be installed in the wet well.. Each

pump shall have a capacity of 60.6 GPM at 24.5 TDH.. Pump motors shall be of the phase, voltage, and minimum horsepower shown on the plans. The actual horsepower of the pump used may be more than that shown on the plans depending on the manufacturer of the actual pump used.

The pump(s) shall be capable of handling domestic sewage. The 2” discharge connection

elbow shall be permanently installed in the wet well or basin along with the discharge piping. The pump(s) shall be automatically connected to the discharge connection elbow when lowered into place, and shall be easily removed for inspection or service. There shall be no need for personnel to enter pump well/basin for pump inspection. Sealing of the pumping unit to the discharge connection elbow shall be accomplished by a simple linear downward motion of the pump. A sliding guide bracket shall be an integral part of the pump unit. The entire weight of the pumping unit shall be guided by no less than two stainless steel guide rails and pressed tightly against the discharge connection elbow with metal-to-metal contact. Sealing of the discharge interface by means of a diaphragm, O-ring or other devices will not be acceptable. No portion of the pump shall bear directly on the floor of the sump. The pump, with its appurtenances and cable, shall be capable of continuous submergence underwater without loss of watertight integrity to a depth of 65 feet.


11307- 3

Major pump components shall be of gray cast iron, Class 30, with smooth surfaces devoid of blow holes and other irregularities. Where watertight sealing is required, O-rings made of nitrile rubber shall be used. All exposed nuts and bolts shall be of AISI type 304 stainless steel or brass construction. All surfaces, coming into contact with sewage, other than stainless steel or brass, shall be protected by an approved sewage resistant coating (choleric rubber paint finish). Impeller shall be sprayed with PVC epoxy primer.

All mating surfaces where watertight sealing is required shall be machined and fitted with

nitrile rubber O-rings. Fitting shall be such that sealing is accomplished by metal to metal contract between machined surfaces. This will result in controlled compression of nitrile rubber O-rings without the requirement of a specific torque limit. No secondary sealing compounds, rectangular gaskets, elliptical O-rings, grease or other devices shall be used.

The cable entry shall be an integral part of the stator casing. The cable entry shall be

comprised of a single cylindrical elastomer grommet flanked by stainless steel washers and a ferrule designed with close tolerance fit against the cable outside diameter and the entry inside diameter. This will provide a leak-proof, torque free seal at the cable entrance. Epoxies, silicones or other secondary sealing systems shall not be considered acceptable.

The pump motor shall be squirrel cage, induction, shell type design, housed in an air-filled,

watertight chamber. The stator winding and stator leads shall be insulated with moisture resistant Class F insulation which will resist a temperature of 155 degrees C (311 degrees F). The stator shall be dipped and baked three times in Class F varnish and shall be heat-shrink fitted into the stator housing. The use of bolts, pins or other fastening devices requiring penetration of the stator housing shall be rejected. The rotor bars and short circuit rings shall be aluminum. At the design point, the temperature in the windings shall not exceed 311 degrees F.

At the maximum rated power of this unit, thermal radiators (cooling fins) integral to the stator

housing, shall be adequate to provide the cooling required by the motor. A minimum of two thermal sensors shall be imbedded in the stator winding end coils. These sensors shall be wired to the control panel for use in conjunction with the external motor overload protection.

The pump shaft shall be of AISI type 240 stainless steel. Each pump shall be provided with a tandem mechanical shaft seal system. The upper of the

tandem set of seals shall operate in an oil chamber located just below the stator housing. This set shall contain one stationary carbon ring and one positively-driven rotating ceramic ring and function as an independent barrier between the pumped liquid and the stator housing. The lower of the tandem set of seals functions as the primary barrier between the pumped liquid and the stator housing. This set shall consist of a stationary ring and a positively driven rotating ring both of which shall be ceramic.

Each interface shall be held in contact by its own spring system. The seals shall require

neither maintenance nor adjustment, but shall be easily inspected and replaceable. The following seal types shall not be considered acceptable nor equal to the dual independent seal specified. Shaft seals without positively driven rotating members, or conventional double mechanical seals containing either a common single or double spring acting between the upper and lower units.

Manufacturers requiring moisture detection devices for warranty shall supply a lockout

device with a manual reset in the control panel.


11307- 4

The pump shaft shall rotate on two (2) permanently lubricated bearings. The upper bearing shall be a single row ball bearing and the lower bearing a two row angular contact ball bearing.
