Overview

FoxRock Properties owns and operates South Shore Medical Center, an 85,000sqft medical facility with 100 examination rooms and 70 medical offices in Norwell, MA. Sanitary waste and wipes are frequently flushed by staff, patients, and visitors and caused major damage to the sump pumps servicing the complex.

Dan Snyder, property manager for FoxRock, explained. “We experienced frequent failures as wipes blocked screens protecting the pumps and wrapped around impellers, clogging volutes, and eventually burning out the pumps’ submersible motors. Even with back-up pumps in place, the service interruptions and maintenance costs became unacceptable.”

Historically the average pump service life ran less than 1.5 years. Finally, after yet another 460-volt submersible pump failure Snyder decided to source a new solu

Solution

In-depth research yielded that most non-clog pumps on the market would still fail with the properties’ high-volume flushed wipe content. They ultimately found Industrial Flow Solutions™ BJM Pumps® dual-shredding SKG series, specifically designed high-volume solids-handling. SKG series pumps’ patented RAD-AX® technology (Radial+Axial) cuts, shreds, and shears solid waste to expedite flow.

A rotating cutter bar with serrated edges that trap and shred solids against sharp grooves in the radial cutting ring creates the radial shredding. As materials are processed through the radial shredding mechanism, the axial cutting components shear any remaining solids with multiple cutting bars. SKG series pumps prevent clogs in wastewater that includes up to 10% solids by volume.

Shredding elements are cast in hardened 440C stainless steel for maximum abrasion resistance and service life. Unlike the originally installed pumps, SKG series pumps do not require screens, eliminating the need to stop operations for manual clean-outs. Combined with the long service life and robust shredding technology, SKG series pumps turned out to be the perfect solids-handling solution for FoxRock Properties.
