State-of-the-art magnetic technology provides a safe and reliable pump for difficult applications. A magnetic coupling consists of two magnet assemblies. One is the outer assembly (the drive magnet) and other is the inner assembly (the driven magnet). The outer assembly is connected to a motor and the inner assembly is directory attached to a pump impeller. When load is applied, the coupling effects angularly and magnets create a force which is used to transfer toque from the motor to impeller. This permanent magnet coupling creates neither slippage nor induction current during rotation. There is no energy loss in this permanent – permanent magnet coupling. ‘Micro-Mach' pumps have an inner magnet assembly which is directly moulded in to the impeller.
