S4T-2 (Ductile Iron Body)

S4TAL-2 (Aluminum Body)

4” (100 mm) Discharge

The S4T-2 and S4TAL-2 solids
handling pumps are designed to be
durable and lightweight yet able to
pump more abrasive liquids. These
pumps incorporate a larger silicon
carbide mechanical seal and
replaceable wear plates. The pump
body can be lined with wear resistant
ceramic or polyurethane coatings for
even more durability.
