Hard Metal Submersible Dry-Pit Vortex Solids-Handling & Sludge Pumps 4330WD Series 

Capacities: 50 to 2,800 GPM
Heads: 5 to 210 feet

Applications ... Fairbanks Morse hard metal submersible dry-pit vortex solids-handling and sludge pumps have proven experience in pumping of solids, slurries, sludge, pulp, trash, sewage and grit. These pump are specifically designed to pass solids, sludge, grit, trash and long stringy materials.

Hard metal submersible dry-pit vortex solids-handling and sludge pumps can be found in sewage and raw water lift stations, many unattended, which require utmost reliability and freedom from clogging and resistance to wear 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, minimize wear, and minimum size driving motors and controls to reduce construction and operation costs. Sewage and wastewater treatment plants and industrial plants where solids handling and grit handling service is required are other typical installations.

The successful application of hard metal submersible dry-pit vortex solids-handling and sludge 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:

Other considerations include:

Features... Parameters of hard metal submersible dry-pit vortex solids-handling and sludge pumps require the units to be available in configurations to meet user needs. Fairbanks Morse meets these demands by providing submersible vortex solids-handling and sludge pumps in 4" and 6" diameter discharge sizes. Pumps are secured to the sump floor with the suction and discharge hard piped. The unit runs continuously non-submerged.

Impellers are semi-open statically balanced vortex design with repelling vanes on the back impeller shroud to reduce stuffing box pressure and balance axial loading. With the impeller recessed out of the fluid flow channel the design assures passage of large solids and long stringy materials. 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 Ni-hard or Hi Chrome volutes, impellers and wear plates, and stainless steel shaft. Shafts are sealed by two separate tandem mounted mechanical seals to protect the motor from the pumped liquid.

Hard metal submersible dry-pit vortex solids-handling and sludge pumps are 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. 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 water jacket. A still tube located in the cooling water jacket allows air to escape as the cooling water enters.
