| A magnetic drive in combination with a liquid separating cup is used for pump technologies if safety requirements or liquids handling requirements demand a leak-free pump construction without a shaft seal.
This magnetic drive system is incorporated in the new magnetic driven, hermetic series (MH) of micro annular gear pumps. The mzr-4661 is equipped with a powerful inner magnet system and an integrated speed control. This first pump of the MH series gives a precise and pulseless volume flow up to 72 ml/min as well as a pressure of 6 bar. This new design is extremely compact, the pump has a diameter of 22 mm and a length of 69 mm.
The materials in contact with the pumped liquid are stainless steel, ceramics and coated NdFeB-magnets. A pump featuring biocompatible materials for use in medical applications is under development.
Applications for this magnetic hermetic pump are typically crystallizing, oxygen sensitve or outgassing liquids as well as fuel cells, AdBlue delivery or dialysis. Any application where avoidance of leakage is an important criterion, this new pump can be used and prove its superiority with it’s long service life.
