SK Series Solids-Handling, Non-Clog Shredder Pumps

Advanced Solids Handling with Integrated Shredding Technology

The BJM Pumps SK Series is designed for solids-handling wastewater applications where clogging is a concern, featuring a high-performance shredding system that tears, breaks, and reduces solids for reliable pump operation.

Engineered for demanding municipal and industrial environments, the SK Series combines robust hydraulic performance with integrated cutting technology to handle difficult solids that would typically clog standard non-clog pumps.

Engineered for Tough Solids

The SK Series incorporates a wear-resistant shredding and cutting system designed to process solids before they pass through the pump. A tungsten carbide-tipped impeller works in combination with a hardened suction plate to tear and reduce debris, allowing the pump to maintain consistent flow.

This design enables handling of solids ranging from approximately 1.6 to 3.5 inches, depending on model.

Built for Durability and Reliability

SK pumps are constructed with cast iron hydraulics and a 304 stainless steel motor housing, providing strength and corrosion resistance in demanding environments. The double mechanical seal system operates within an oil-filled chamber, ensuring long service life and reliable sealing.

Embedded thermal protection and Seal Minder® moisture detection provide additional protection against overheating and seal failure.
