NovAseptic® Mixers

 

The Merck NovAseptic magnetic mixer range meets the technical need to mix ultrapure fluids in sterile tanks, with no risk of contamination.

 

The principle is that there is no penetration through the tank wall. A magnetic, and therefore contactless, coupling connects an external drive to an impeller inside the tank.

 

This technology has been developed and refined by NovAseptic for more than 30 years.

 

The reputation of this range is confirmed by the number of systems installed at pharmaceutical, cosmetics and food-processing sites.

 

This equipment is manufactured in France and Sweden.

 

The NovaSeptic brand belongs to the Merck group.

 

MERCK NovAseptic® Magnetic Mixers: what a complete assembly includes

 

It is a modular system made up of four elements:

 

A tank flange: this is the element that supports the mixer in the tank. The flange can be welded, or removable from the top or from the bottom, depending on the option chosen.

 

A complete drive unit: it includes an AC or DC motor, a gear motor, a magnetic coupling core and a connection flange.

 

The impeller: this is the rotating propeller inside the tank.

 

The male bearing: this is the hub that holds the impeller in the tank. It can be made of ceramic (Ssic), zirconium, or diamond-coated (UNCD).

 

MERCK NovAseptic® Magnetic Mixers: certificates and technical standards

 

All product-contact parts are fully traceable:

 

For metal parts: 3.1 certificate with 2.2 roughness and electropolishing certificate

 

Standard: 316L 1.4435 BN2 Ra<0.38µm electropolished

 

Duplex and super-austenitic grades also available

 

For seals: FDA and USP Class VI certificate

 

For gaskets: FDA, USP, ADI Free, TSE/BSE certificate

 

Available options: ATEX, CFD simulation, special designs, pre-validation in a test tank.

 

 

The Novaseptic USM mixer range

 

The USM range is ideal for mixing powders or salts into liquids.

 

Designed to create a deep vortex that draws solid particles down towards the impeller.

 

The USM range combines high flow and high shear , a cost-effective alternative to the GMP range for products that are not shear-sensitive.
