Tank Weld Plate - Providing a Flexible Platform

By: Steridose  09-12-2011
Keywords: Stainless Steel, bearing

The weld plate is welded onto the tank bottom and is made out of AISI 316L stainless steel. Comparable SMA and SMO models fit into the same weld plate and bearing, making it easy to exchange impeller types.  Additionally, in most weld plate sizes, more than one size mixer can be installed, providing a flexible platform.

Overview of Sterimixer Magnetic Coupled Mixer

Steridose is continuing a long-term commitment to supply and support Sterimixer® products, together with its focus on manufacturing excellence and future product development. The impeller contains permanent magnets that create a magnetic coupling with the magnet rotor. Complies with all relevant pharmaceutical regulations. Sterimixer consists of the following components. For vessels from 5 liters - 30.000 liters.


Rotating Bearings for Impeller surface

This proven design provides a flat rotating surface that combined with the design of the magnetic coupling ensures rotational stability. The journal bearing design minimizes rotating elements and contact surfaces, therefore limiting particle generation. Ensures that the bearing is effectively cleaned during CIP/SIP. The bearing assembly consists of male and female bushings.


Designed with Easy cleaning - Impeller Options

SMO is an open design that exposes all surfaces to the cleaning solution just by means of directing flow from a spray ball to the impeller head. During cleaning, the flow channels force cleaning fluid through the bearing area, providing very effective and repeatable cleaning results. SMA generates very low shear forces, which makes it ideal for applications with shear sensitive products, such as mammalian cell cultures.


Magnetic Coupling - Radial Design for String Magnetic Coupling

The design of the magnetic coupling is key to a proper operation of the mixer unit, in particular of the bearing assembly. The Sterimixer coupling does not create any additional forces to the bearing while the impeller rotates. The magnetic coupling design is radial, which creates a very strong magnetic coupling. This allows Sterimixer to work with products with viscosities up to 1,000 cP.


Drive Unit - with angled Gearbox Option

Some models are equiped with bayonet coupling that facilitates installation/removal of the drive unit. Drive Units are offered in different types, such as AC, DC, Stainless Steel, Explosion Proof and AIR. It consists of the magnet rotor, gearbox and motor. The angled gearbox reduces the space requirement.
