The Little Giant 2-MD Series Magnetic Drive Pumps feature 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. The 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. The spindle shaft is supported at both ends to prevent impeller damage during the start and stop of the pump.
