<br />OF
<br />UMP STATION SPECIFICATION
<br />Contractor shall furnish and install as shown on these drawings and as described
<br />in these specifications one duplex submersible type sanitary sewer pumping station
<br />complete, including, pumps, motors, electrical controls, quick disconnect system, wet
<br />well and discharge piping.
<br />PUMP AND MOTOR CONSTRUCTION:
<br />Pumps shall be of the heavy duty non—clog type capable of pumping unscreened
<br />sewage consisting of water, heavy sludge and spherical solids up to 2-1/2 inches in
<br />diameter.
<br />Each pump shall have a capacity of 60 GPM O 30' TDH with 50% min. efficiency.
<br />Motors shall be 2 H.P., 1 phase 60 HZ, 240 volts. Both pumps and motors shall
<br />have the capability of running dry for extended periods without damage to motor seals.
<br />Pump volute, motor enclosure and seal housing shall be ASTM A-48 Class 30 cast
<br />iron or better. All fasteners exposed to the pumped liquid and the motor shaft
<br />on which the impeller is mounted shall be stainless steel. Impeller shall be single
<br />or mulitple port enclosed type. Impeller diameter shall be trimmed to meet
<br />specified system flow and head conditions. The inner seal shall operate in a sealed,
<br />oil—filled chamber containing moisture sensing probes capable of detecting any
<br />influx of conductive liquid past the outer seal. Pumps shall be "PACO", "FLYGT"
<br />or approved equal. Replacement parts must be locally available (within a 200
<br />mile radius).
<br />ELECTRICAL CONTROLS:
<br />All electrical controls for the pump station shall be mounted in a NEMA 3R
<br />double—door, dead—front enclosure with a padlock hasp. The controls for each
<br />pump shall include a thermal circuit breaker, a rotary hand—off automatic switch,
<br />a thermal magnetic motor starter with ambient compensated overload relays
<br />and quick trip heaters, running lights and elapsed time meter.
<br />Pump operation shall be controlled by four bulb—type liquid level sensors (Flygt
<br />Model ENP -10 or equivalent): one for lead pump turn—on, one for lag pump turn—on,
<br />one for both pumps turn—off, and one for high water alarm. The pumps shall operate
<br />singly or in parallel. An automatic alternator shall alternate the lead—standby duty on
<br />each succeeding pump cycle. A 0-10 minute adjustable delay timer shall be included in
<br />the lead pump activation circuit. The pumps shall be set
<br />to turn off 2.5 feet above the bottom of the wet well. The on—site alarm shall
<br />include a flashing red light and horn. The alarm circuit shall include 2 spare contacts
<br />for use in transmitting alarm to remote location.
<br />The design of the disconnect system shall permit the easy removal of pumping
<br />units for inspection or service. The pump when lowered into place, shall be
<br />automatically connected to the discharge piping. There shall be no need for
<br />personnel to enter the wet well to inspect or service the pump. Pump shall be
<br />securely attached to a sliding guide bracket. A minimum schedule 40 standard
<br />stainless steel pipe guide rail shall be furnished and installed by the contractor.
<br />The sliding guide bracket shall have non—sparking material at the point of contact
<br />with the guide rail to prevent spark ignition of explosive wet well gases during
<br />pump installation and removal. A cast iron discharge elbow, located on the floor
<br />of the wet well, will receive the pump discharge when the pump is lowered into
<br />place. The receiving edge of the discharge elbow shall be fitted with non—sparking
<br />material to prevent spark ignition of explosive wet well gases during pump
<br />installation and removal. The pump discharge shall be fitted with a resilient seal
<br />which provides a positive hydraulic seal for maximum pump system efficiency.
<br />The lower guide rail bracket shall be mounted by the pump manufacturer on a steel
<br />base plate, in alignment for proper operation of the disconnect system. The base
<br />assembly shall provide stable, three point support of the pumping unit during pump
<br />operation. The entire quick disconnect pumping system must be listed and labeled
<br />by underwriters laboratory (UL) as suitable for operation in Class 1, Group D,
<br />Division 1 located as defined in Section 501-8 of the National Electric Code.
<br />DISCHARGE PIPING:
<br />The discharge piping for each pump shall include cast iron discharge elbow,
<br />schedule 80 PVC and flanged fittings, 175 PSI flanged check valve with spring assist,
<br />especially designed to handle raw sewage, 125 PSI flanged gate valve and flexible coupling.
<br />WET LLTYEL
<br />The wet well shall be constructed of 6 feet diameter Class III reinforced concrete
<br />pipe (R.C.P.) with PCC base, fully lined with coal tar epoxy or reinforced fiberglass
<br />on a PCC base.
<br />TESTING:
<br />The entire installation shall be tested in the presence of the owner. Panel and circuits
<br />shall be tested for shorts and ground with mains and disconnect from feeders. Each
<br />individual circuit shall be tested at the panel with all equipment connected for proper
<br />operation. The actual flow rates shall be measured for all phases of operation. The
<br />actual flow rates shall be within 10% of the specified design. flow rates when tested
<br />at the design head.
<br />OPERATION AND MAINTENANCE:
<br />Contractor shall furnish the owner three (3) bound sets of 0 & M manuals
<br />including complete wiring diagram, exploded view of all electrical components, pump
<br />equipment and pump curve, all part numbers and one laminated wire schematic in
<br />pocket on panel door. He shall also provide the owner the name, address
<br />and phone number of the nearest local distributors for parts.
<br />WARRANTY:
<br />All material including pumps, valves, electrical controls, etc. shall be warranted for
<br />a minimum one—year period from the date of final acceptance by the Owner.
