SPX FLOW Lightnin MagMixer MBE magnetic mixer

SPX FLOW has announced the release of a magnetic mixer, the MagMixer MBE, from its Lightnin brand. The mixer has been designed for good operation and regulatory compliance in life science applications.

The unit has no shaft penetrating the tank and so requires no mechanical seals, which reduces the risk of leakage or microbial contamination. It provides high torque capacity with easy cleanability and, with bottom-mounted magnetic agitators, is suitable for low-viscosity blending, dissolving solids and solid suspension in sterile applications.

Engineered using computational fluid dynamics (CFD), it utilises Lightnin A281 three-blade hybrid axial/radial impellers in an open construction that maximises flow while facilitating easy cleaning and sterilisation (CIP and SIP). Alongside optimising product flow, the impellers contain strong magnets which produce high levels of torque capacity in a compact form.

The magnetic impeller removes the need for shaft and seals. Strong, oversized ceramic bearings reduce the risk of breakage, are product lubricated and produce good mixer stability and performance. The mixer further ensures low-maintenance overheads as the bearings can be easily replaced on-site and there is no need for a spare impeller. Magnetic lifting of the impeller reduces the load on the surface of the bearings and enables the mixer to continue to run until the mixing vessel is completely empty.

The product is controlled by a variable frequency drive (VFD). The series covers a wide power range from 0.09 to 7.5 kW (0.12 to 10 Hp), with operating speeds of between 200 and 1000 rpm. A range of options are available, including different bearings, O-rings, drive and body materials.
