Alfa Laval LeviMag® UltraPure Mixers

Introduction

The Alfa Laval LeviMag® UltraPure is an aseptic magnetic

mixer that uses a patented levitating impeller and advanced

design to mix down to the last drop and maximize product

yield.

Compact, energy-efficient and easy to maintain, it provides

dry-running capabilities and efficient mixing at low speeds,

which ensures gentle product treatment, as well as at high

speeds for high-intensity mixing. This provides greater

process flexibility to handle a wide range of fluid types and

mixing duties.

Its open design and low-speed rotation during cleaning

contribute to no dead zones, effective residue removal and

minimize contamination risks from wear particles. All this

contributes to fast return on investment and maximum

product yield in tanks ranging in size between 30 litres and

40.000 litres.

It is supplied with Alfa Laval Q-doc, a comprehensive

documentation package that provides full transparency of the

entire supply chain and helps make the validation process

easy.

Applications

Alfa Laval LeviMag UltraPure offers effective mixing for multiple

processes, such as those involving serums, vaccines, plasma

fractions, bacteria and cell cultures, and APIs, in the

biotechnology, pharmaceutical and other industries with

demanding sterile or high-purity applications.

Benefits

• Maximum process efficiency, minimal product loss

• Optimal flow with higher efficiency and less energy

consumption

• Mixing down to the last drop for maximum yield due to low

agitation and dry-running capability

• Optimized Cleaning-in-Place (CIP) due to full drainability

• Minimized downtime due to ease of maintenance

Standard design

The Alfa Laval LeviMag UltraPure consists of a detachable

drive unit, levitating impeller unit with radial blades, seals,

ceramic bearings and magnetic coupling, weld plate and

connections. It is available in five sizes, with mixing speeds

ranging from 10 rpm up to 800 rpm.

Working principle

An impeller with radial blades installed inside the tank rotates

due to the torque from the magnetic coupling. The rotation of

the impeller mixes the fluid inside the tank. The unique design

of the Alfa Laval magnetic coupling ensures the levitation of

the impeller at all times. This enables dry-running and

complete drainability of process fluids from the tank possible.

This ensures highly efficient mixing down to the last drop and,

subsequently, maximum yield. It also enables the free flow of

CIP liquid and steam around all parts of the mixer, thereby

ensuring thorough cleaning. Impeller levitation also eliminates

axial wear.
