Alfa Laval LeviMag® Aseptic Magnetic Mixers

Introduction

The Alfa Laval LeviMag® 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 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 / 8 US

gallons and US 10.567 gallons.

It is supplied with 2.2 certification as standard but can

optionally be supplied with Alfa Laval Q-doc, a comprehensive

documentation package that provides full transparency of the

entire supply chain.

Applications

Alfa Laval LeviMag magnetic mixer offers effective mixing for

multiple processes in the dairy, food, beverage, biotechnology,

pharmaceutical and other industries that have demanding

requirements for sterile or aseptic storage or processing.

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 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.
