Hygienic Magnetic Mixer

The MagMixer MBE Series from SPX Flow is a hygienic magnetic mixer that meets current operational standards and regulatory compliance and is suitable for low-viscosity blending, dissolving solids, and solid suspension in sterile applications.

The mixer has bottom-mounted magnetic agitators, is engineered using computational fluid dynamics, and uses Lightnin A281 3-blade hybrid axial/radial impellers in an open construction that facilitates improved cleaning and sterilization. Magnetic impellers remove the need for shaft and seals, which significantly reduces the risk of leakage or microbial contamination, according to the company. SPX Flow reports that, in addition to optimizing product flow, the impellers also produce high levels of torque capacity in a compact form.

Robust ceramic bearings reduce the risk of breakage, are product-lubricated, and enhance mixer stability, reliability, and performance, as stated by the company. The bearings can be easily replaced on-site with no need for a spare impeller.

The unit is controlled by a variable frequency drive and covers a power range from 0.09 to 7.5 kW (0.12Hp to 10Hp) with operating speeds between 200-1000 rpm.

According to SPX Flow, 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, improving formulation mixing. Range options include a variety of bearings, O-rings, drive, and body materials.
