The Little Giant MD-HC series features leakproof, seal-less magnetic drives and are designed for in-line, nonsubmersible use. 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-up and stop of the pump. For use in the circulation of highly corrosive acids, alkalis, solvents, brine, plating solutions, sterile solutions, and other highly corrosive chemicals and solutions that are compatible with the pump's material of construction. The workhorse pump is for highly corrosive chemicals and solutions. Although the PVDF pumps do not have run dry capabilities, they handle the broadest range of highly corrosive chemicals with pH values to 11. These pumps have proven themselves to withstand running dry for up to 8 hours without damage.
