The Kweng Sealless Magnetic Drive Pump — Internal Gear employs the proven internal gearing (gear within gear) principles for pumping. It has a magnetic drive and a containment shell that hermetically seals the liquid inside the pump, giving it the highest level of liquid containment possible by getting rid of the traditional dynamic shaft seals that are usually used for dangerous, hard-to-seal, or expensive liquids.
Kweng Sealless Magnetic Drive Pumps — Internal Gear are categorized into:
MD-IGP: Designed to handle both thin and thick liquids, the MD-IGP Series Sealless Magnetic Drive Pumps can operate in either direction. They are also capable of operating under suction lift conditions.
