Applications ... Fairbanks Morse submersible solids-handling pumps have over 40 years of proven experience in pumping of solids, slurries, sludge, pulp, trash, sewage and grit. These pump are specifically designed to pass solids, trash and long stringy materials.
Submersible solids-handling pumps can be found in sewage and raw water lift stations, many unattended, which require utmost reliability and freedom from clogging or other downtime maintenance. Plants demand pumps to provide sustained high performance, the best possible design to resist clogging, and minimum size driving motors and controls to reduce construction and operation costs. Sewage and wastewater treatment plants and industrial plants where solids handling service is required are other typical installations.
The successful application of submersible solids-handling pumps requires the consideration of many elements. In addition to knowing the capacity and discharge head requirements, other factors which need to be evaluated include:
- Net Positive Suction Head Available (NPSHA) and submergence
- Maximum operating pressure
- Capacity operating range
- Horsepower required throughout the pump's operating range
- System head curve
- Sump requirements
Other considerations include:
- Parameters of the liquid being pumped
- Allowable solid size
- Elevation
- Driver requirements
- Material of construction
Features... Parameters of submersible solids-handling pumps require the units to be available in configurations to meet user needs. Fairbanks Morse meets these demands by providing submersible solids-handling pumps in discharge sizes from 2" to IO" in diameter. Pumps can be of the pull-up type configuration allowing the user to quickly pull the unit out of the wet well for inspection. The discharge connection is made with the discharge elbow as the pump is lowered in place. Optional submersible configuration provides a pump which rests on the sump floor and is hard piped to discharge piping.
Pumps, motors and pull-up systems are UL Listed for operation in Class I, Division 1, Group C and D hazardous locations, and feature explosion-proof construction.
Impellers are single-suction, mixed-flow design with large passageways, vanes with blunt well-rounded leading edges and a thick hydrofoil shape preventing long stringy material from wrapping around the leading edge. Impellers are matched with thick-wall equalizing-pressure, constant-velocity volutes. This design channels the flow away from the impeller vanes into the circular flow area of the impeller passageways and casing, to ensure passage of large solids and long stringy materials, reduce turbulence and radial and bending shaft forces. Abrasive wear is minimized, bearing, mechanical seal and shaft life is lengthened, and mot important, maintenance and downtime costs are greatly reduced, resulting in true savings. An added advantage is a smooth, quite and trouble-free installation.
Material of construction include cast iron volutes, cast iron or bronze impellers and stainless steel shaft. Shafts are sealed by two separate tandem mounted mechanical seals to protect the motor from the pumped liquid.
Pump is driven by a UL Listed submersible motor with superior sealing features over other submersible motor designs to ensure a durable long life unit. In fact, Fairbanks Morse backs their submersible units with a five-year prorated warranty.
