DESCRIPTION The "MG 200" Series Magnet Drive Gear Pumps are compact precision performance products for high technology applications. The magnet drive principle provides a totally sealed pump chamber which is capable of handling a wide range of corrosive liquids with a high degree of safety. The housing of these gear pumps and the internal metal parts are in AISI 316 stainless steel. The standard gears are PEEK (PTFE and Ryton available, consult factory).
In operation, the MG 200 Series pumps are noiseless, pulsation-free and capable of handling relatively hot liquids, i.e., 120°C (248°F) at a low coefficient of expansion. The principle of the magnet drive comprises an inner magnet embodied in the pump, connected to the driving gear, and an outer magnet connected to the motor shaft. The pole-to-pole alignment of the magnets provides the driving motion to the pump. Decoupling occurs when the pump load exceeds the coupling torque between the magnets.
In/Out ports have 1/8 NPT female threads. A built-in relief valve is available upon request.
