Applications > Maintenance in suspension

The maintenance in suspension process precedes suspension. It involves mixing two bodies of different sizes (liquid/solid) in order to, thanks to the force of movement and the energy generated, raise all the bodies in the vessel and keep them moving. The fluid will thus drag the isolated solid particle in a regular movement somewhat different from its own.

The process of maintaining in suspension allows a solid/liquid mixture to be made so that this operation ensures the homogenisation of the solid parts in the liquid phase thanks to the movement created by stirring in a container (usually a tank) and the energy power it generates.


The objective of this process is therefore to homogeneously preserve all the solids in suspension in the solution present in the tank by means of a regular movement, while keeping the bottom clear.

Suspension maintenance operations are carried out using stirrers equipped with moving parts such as propellers, turbines or anchors, selected according to the type of products used, the quality and properties of the mixture to be obtained and the duration of the required suspension maintenance, generally until the tank or other type of tank is completely emptied.


Turbines for agitators with curved, straight or inclined blades are often used at the bottom of the tank to optimise their important centrifugal effect, to shear and keep solid products in suspension to avoid their sedimentation and settling, while maintaining the mixing effect and its homogenisation until the end of the operation. 


Maintenance in suspension is a process that responds to many applications in the chemical, pharmaceutical, cosmetic or food industries.
