2 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

3 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

High level alarms or other alarm conditions. Guide rail or free standing type designed pumps. Fiberglass basins and accessories. Factory assembled and tested unit with basin, pumps, valves and controls-preassembled and wired. Notes: 1. Motors designed for 20 starts per hour. Level devices and pit depths should be designed to maintain starts per hours at maximum 104 degree F for typical sewage pump applications. 2. Float devices require 8-12 of water level differential from low float(off) to high float(on) position. Basins should be designed to accommodate float level differential. 3. High water alarm float (on level) should be designed to activate at 6 below bottom of invert to prevent any fluids backing into the supply lines. Float switch tilt travel of 12 should be considered. 4. For higher temperature applications (above 104 degree F) contact factory for special motor insulation, special float materials and special accessories that may be required to sustain operation in higher temperature settings. 5. Most fiberglass basins limit temperatures to less than 120 degree F. For temperatures in excess of 120 degree F where fiberglass basins are required, contact the factory for special assistance /21/2015 5

6 Fully automatic Quick Disconnect sewage pump system designed for ease in installation and future pump maintenance. Available in factory assembled systems or shipped loose for field assembly with fiberglass basins and gas tight covers. The MSC-QD provides a formidable sewage ejector system combining technological material advancements with grinding and shearing action reducing sewage waste to shredded particles. Guide rail QD system allows pumps to be installed or removed by guiding the pump up and down the installed guide rails and not requiring bolted connections to the discharge piping. Tungsten carbide edged impellers rotating against hardened chrome plates grind and shear sewage waste solids to particle sizes. Complete set of QD accessories including lifting chains, guide rails, covers, frames, basins and gas tight lids, floats and associated control panel or fully integrated packaged systems are available based upon system requirements and specifications. 7/21/2015 6

Motors Motors will be air-filled and provided with 20 feet of submersible power cable and shall be NEMA MG-1, design type B equivalent and rated at full load amps. Motor(s) shall have a 1.15 service factor and shall be rated for 20 starts per hour. Motor(s) shall be air filled, copper wound, class E or F insulated with built in thermal and over current protection for each winding.

The cable entrance shall incorporate built in strain relief and a combination three way mechanical compression sealing with a fatigue reducing/thermal expansion boot. The cable entrance assembly shall contain a antiwicking block to eliminate water incursion into the motor due to capillary wicking should the power cable be accidentally damaged. Motors will be provided with thermal overload protection and seal failure sensors. Controls Pump manufacturer shall provide a Federal Pump series SBS duplex level control system including duplex control panel (for wall mounting) and accessory alarms as detailed in this specification. Duplex Sewage Pump Controller shall include: individual circuit breakers with thru-the-door disconnect handles, across-the line type magnetic starters with overload protection, hoa selector switches, pilot run lights, control circuit transformer with fused secondary, automatic lead/lag alternator, high water alarm light, seal failure alarm light and common alarm horn with silence push button, control relays and numbered terminal strip.

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.
