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 and bushings are available in PEEK™ or PTFE™. Other materials, as well as a range of driving magnets are available. NSF certified gear pumps for potable water or fluids for human consumption are also available. In operation the MG series pumps are noiseless, pulsation-free and able to handle relatively high temperature fluids up to 120°C (248°F) with low coefficient of expansion.
The pump is capable of a flow range from 20 to 250 l/h (5 to 66 GPH) and pressures to 15 bar (218 psi). The principle of the magnetic drive comprises 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 occurs when the pump load exceeds the maximum coupling torque provided by the alignment of the two magnets.
