The Little Giant 4-MD series features leakproof, seal-less magnetic drives designed for in-line, non-submersible use. This series is known for its excellent wear and corrosion resistance in the circulation of mildly corrosive acids, alkalis, solvents, brine, plating solutions, sterile solutions, and other mildly corrosive chemicals and solutions compatible with the pump’s material of construction.
The 4-MD Series features a 1/12 horsepower open FC motor with 1/2″ FNPT inlet x 1/2″ MNPT outlet and maximum head of 23.7′ capabilities. Shaft and thrust washers are titanium for excellent wear resistance 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.
