Magnetic drive (mag-drive) pumps utilize magnets to turn the impeller inside the housing, which transfers liquids through a system. The impeller and pumping fluid are sealed from the motor's drive shaft, making these pumps suited for handling corrosive liquids. Chemical-resistant magnetic-drive straight centrifugal pumps have an intake connection in-line with the impeller's eye and pump shaft. Pump heads for chemical-resistant magnetic-drive centrifugal pumps do not include a motor.
