The Little Giant 1.5-MDI-SC series features leakproof, seal-less magnetic drives and are designed for in-line,
non-submersible use. Volute, magnet housing and impeller are glass-lled polypropylene for excellent chemical
resistance. Ceramic shaft and thrust washers are 99.5% pure alumina 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.
