The MG series magnet drive gear pumps are compact
precision performance pumps for high technology applications.
The magnet drive principle provides a totally sealed pump
chamber capable of handling a wide range of corrosive liquids
with a high degree of safety. The housing of the pump and the
internal metal parts are in AISI 316L stainless steel and the gears
are available in Peek™, Ceramic Peek™ or PTFE™.
In operation the MG series pumps are noiseless,
pulsation-free and able to handle relatively high temperature
fluids with low coefficient of expansion.
The principle of the magnetic drive compries an inner magnet
embodied in the pump and connected to the driving gear, and
an outer magnet connected to the motor shaft.
The pole-to-pole alignment of the two magnets provides the
driving motion to the pump. Decoupling will occur when the
pump load exceeds the maximum coupling torque provided by
the alignment of the two magnets.
