Magnetic Hermetic Series



The mzr-4661 is the first pump of the new magnetic driven, hermetic MH series. Equipped with a powerful inner magnet system and an integrated speed control, it reaches a precise and pulse less volume flow from 4.8 ml/min up to 72 ml/min as well as a pressure of 6 bar. Especially, the compact dimensions have to be outlined. The pump has a diameter of 22 mm and a length of 69 mm. Applications for this magnetic hermetic pump are typically crystallizing, oxygen sensitive or outgassing liquids as well as fuel cells, AdBlue delivery or dialysis. All areas, where avoidance of leakage is an important criterion this new pump can be used and prove its superiority regarding to long service life.
