Hayward S Series vertical seal-less immersible centrifugal pumps are designed for reliable transfer and circulation of aggressive fluids. The non-metallic, seal-less construction eliminates leaks and seal replacement while providing excellent chemical resistance. Precision-molded, dynamically balanced enclosed impellers allow pumping of abrasive solutions and safe operation against a closed discharge valve.
These pumps are available from 1/15 HP through 5 HP with pump heads in CPVC, glass-filled polypropylene (GFPP) or PVDF. A PTFE fume barrier protects the motor and bearings from corrosive vapors. Motors are matched to the pump for non-overloading, continuous-duty performance across the entire operating range.
