About Little Giant Quarium Series Pumps

MDQ and MDQX aquarium pumps are non-submersible, magnetic drive pumps used for in-line filtration, recirculation, tank return and other applications which involve handling fresh and salt water. These pumps feature a thermally protected, UL listed and CSA certified magnetic drive motor which resists overheating caused by clogging of the impeller by sludge, seaweed and other media.
MDQ series have a higher head and lower flow rating, whereas MDQX has a lower head and higher flow.
Aquarium pumps are most commonly installed in the cabinet below the aquarium, which contains filtration and other equipment.

Quarium series pumps incorporate a glass-filled polypropylene volute, ceramic shaft and washers, ceramic coated impeller driven magnet and Nitrile O-rings.
