The Little Giant MD series features leakproof, seal-less magnetic drives and are designed for in-line, non-submersible
use. Volute and magnet housing are glass-filled polypropylene for excellent chemical resistance. Impeller is glass-filled
polypropylene and ceramagnet “A” (barium ferrite). Shaft and thrust washers are titanium for excellent wear and
trouble-free service. Pumping heads are easily rotated, cleaned or serviced with no special tools required. Spindle shaft
is supported at both ends to prevent impeller damage during start-up and stop of pump.
