    • Wastewater transfer in classified and hazardous locations

    • Non-clog scroll duty on solids-bearing water

    • Stormwater, process pits and plant sumps

    Compatibility

    Fits the ShinMaywa CNWX explosion-proof submersible sewage pump at the 1.5 kW / 2 HP rating: 4CNWX41.5T3E (4 in. discharge, four-pole, three-phase 460V, explosion-proof) and 4CNWX41.5T. Both take the same seal stack. Running a different horsepower? The CNWX changes seal size with the rating, so use the links below rather than assuming one kit covers the range.
