Capacities to 450 GPM Heads to 65 Feet HP to 10 HP-1750 RPM Introduction Federal Pump MSC Sewage Pumps provide for the lifting and disposal of sewage and sewage related fluids from retaining basins or concrete pits and are pumped to city waste disposal lines where these fluids cannot drain under gravity conditions alone. Typically located below grade, sewage pumps provide building owners the ability to design and locate restroom or other facilities below ground that are serviced by these sewage lift stations. In addition to their use in buildings, Federal Pump MSC chopper pumps are used in municipalities, larger residential buildings, below ground parking structures, industrial waste facilities and other areas where these sewage and waste particulates are collected and pumped to other locations. MSC chopper pumps differ from industry standard centrifugal sewage pumps that pass solids thru the impeller by actually shredding and grinding these solids within the pump; not allowing larger solids the opportunity to clog the pump, piping or disposal system. Hardened tungsten carbide edged rotating impeller cutting and chopping against stationary chrome hardened suction plate reduce larger solids to mere particles and prevent any downstream clogging that may occur when larger solids are pumped thru the impeller and into the piping system. Supported by heavy duty industrial shafts, bearings and increased motor insulation, the MSC pumps provide 20 starts per hour on/off cycle time capabilities and are supported with Federal Pump s 3 Year Warranty. Supported by Federal Pump s SBS Simplex, Duplex and Triplex controls systems, the MSC sewage pump system supports 24 hour per day/7 days per week automatic operation for standard sewage pump services. Available in QD (Quick Disconnect Design) or free standing designs, the MSC product offering provides the end user with trouble free operation when designed, installed and maintained properly. 7/21/2015 2

Neoprene power cable sheath for temperatures to 80 degree C (170 degree F) Submersible air-filled motor copper wound-class B insulation (available in Class F for higher temperature requirements) Standard product provides 20 starts per hour. Double shielded permanently lubricated high temperature C3 ball bearings rated for B-10 bearing life of 60,000 hours. Double inside mechanical seals with silicon carbide faces for extended seal life with nitrile-buna elastomer. Stainless Steel exposed fasteners. Rugged cast iron pump case provides for metal to metal guide rail connections where pump and discharge mating connects are sealed tight for optimum performance. Innovative triple protection motor/cable ends sealed with epoxy resin or molded rubber with built-in power cord strain relief. All units include antiwicking block to eliminate water intrusion into the motor. Built-in thermal motor protection prevents motor failure due to overloading, single phasing (for three phase units) or accidental extended run-dry conditions. Oil bath seal housing provides optimum seal lubrication and extended seal life and keeps mechanical seal away from pumped media. (Optional) Seal failure protection senses water intrusion into seal area with auto pump shut down and alarm condition. Sintered tungsten carbide tipped cast iron impeller rotating against high chromium cast iron field replaceable and adjustable cutter- Brinell Hardness factor of 550- plate/suction cover reduce solids to shredded particles. 7/21/2015 3

The SBS control package will include a NEMA 4 junction box and mounting mechanism with float switch cable compression fittings to ensure float switches remain aligned along with (4) non-mercury type tilt level switches. The contractor shall set the level switches as shown in the plans and ensure the high water alarm is set at least 6 below the bottom of the invert. Basin/Pit Accessories The pumps will be installed as shown in the plans. The pump manufacturer will provide the appropriate sized aluminum gas tight cover assembly, spring loaded with hinged cover to allow the pumps to be lifted out of the pit for service and repair. Pump manufacturer will provide base elbows for mounting in basin bottom, guide gar brackets for mounting at upper basin position, stainless steel guide rails that connect to lower base mounted elbow and stainless steel lifting cable connected to lifting lugs provided in motor assembly. Sequence of Operation: Upon rise in liquid level to a predetermined point the lead float switch will initiate lead pump operation and complete the pumping cycle to a predetermined pumps off set point. If the influent conditions rise above a certain rate where the lead pump alone cannot satisfy demand, the lag pump will start at a predetermined set point and work in parallel with the lead pump to satisfy system conditions and pump down to pumps off level. The lead and lag pumps will alternate cycles every 24 hours for even pump loading. In the event a high water level condition occurs, the high water level alarm float switch will activate an alarm horn and light to signal the condition. In the event the lead or lag pump fails the alternate pump will maintain pump conditions until the level is reduced to pumps off set point. An alarm light will be activated along with the alarm horn should one of the pumps fail notifying the user of a failed pump condition. Start-Up Federal Pump s manufacturer representative will review the installation and be available for start-up. Start-up will include a minimum of (4) complete run cycles and simulated alarm conditions to ensure system operation is complete and to specification. 7/21/2015 26
