Applications ... Fairbanks Morse submersible dry-pit angleflow 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 dry-pit angleflow 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 and specifically where there is a chance for station flooding. 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 dry-pit angleflow 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 dry-pit angleflow 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 IO" to 24" in diameter. Pumps are secured to the sump floor with the suction and discharge hard piped. The unit runs continuously non-submerged.

Pumps and motors are UL Listed for operation in Class 1, 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. This design assures passage of large solids and long stringy materials, and reduces turbulence and radial and bending shaft forces. Conservative bearing ratings and oversized shafts are designed for low radial stress to reduce shaft deflection and ensure years of reliable, trouble-free service under any load during abnormal conditions.

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 withafive-yearproratedwarranty. These run-dry motors are water jacketed utilizing a portion of the liquid being pumped to carry away motor heat. A unique, self-cleaning rotating flow-control disc prevents virtually any solids from entering and accumulating in the mechanical seal area and cooling waterjacket. A still tube located in the cooling water jacket allows air to escape as the cooling water enters.
