Proven agitator for aqueous, low-viscosity applications.
The propeller agitator, also known as mixing propeller, is particularly suitable for stirring processes in aqueous and low-viscosity media. Areas of application of a propeller include homogenizing, dispersing and suspending liquid media. Propeller agitators require very little maintenance and are also suitable for continuous operation. Propeller stirrers are usually installed eccentrically on top of the tank and are also suitable for circulating media in large tanks and storage tanks, despite the small power input. In large storage tanks, propeller agitators are often installed laterally in the cylinder of the vessel to keep the medium in motion. The speed of a propeller agitator depends on the design. A high-speed mixer (without gear) reaches speeds of up to 1500 rpm. Propeller stirrers with geared motors are suitable for gentler stirring applications and their speed can be significantly reduced accordingly.

Versatile agitator for aqueous to medium viscosity applications.
The blade stirrer (also called cross blade agitator or paddle stirrer) is a multi-stage agitator system, since at least two blade elements are attached to the agitator shaft. The large blade diameter creates a high peripheral speed. A blade agitator is therefore always equipped with a gear motor that regulates the agitator speed to a two-digit or low three-digit value. The blade stirrer is installed eccentrically on top of the tank and therefore does not require any additional flow breakers. One advantage of the blade stirrer is the very wide range of applications, as it reliably mixes aqueous media but also gets along well with much more viscous media such as motor oil, syrup or low-viscosity paints. Blade stirrers are also well suited for the gentle circulation of large quantities.

Wall scraping slow-speed agitator for gentle mixing of highly viscous media
The homogenization of viscous media such as honey or glue places high demands on mixing technology. However, anchor agitators, also known as frame stirrers, are the optimal agitator options for such highly viscous media. Anchor agitators are characterized by the intensive renewal / mixing of the wall boundary layer, which results in good heat transfer. The main flow direction is tangential with vortex areas on the anchor bars. Small areas with relatively small flow speeds are formed between the anchor bars, which is why Behälter KG anchor stirrers are equipped with solid stainless-steel built-in parts in order to achieve maximum mixing. Centrally positioned on the top bottom of the tank and optionally equipped with Teflon wipers, the anchor mixer is the best choice for gentle stirring of highly viscous media.

Anchor agitator of the Behälter KG SDE-Flexmix product family
Behälter KG has designed a brand-new anchor agitator mixing tank, available in 550 and 1150 liters. It is called SDE-Flexmix. We also offer larger 800 – 20000 liter mixing tanks with anchor stirrer, that can be mounted on our FIT-Storemix (requires a custom-made design).
We also have a very large selection of used stainless steel tanks with anchor agitators always immediately available from stock.
State-of-the-art cone-shaped stirring elements for efficient and energy-saving agitation.
Cup stirrers, also known as visco-stirrers, are one of the most innovative and versatile agitator variants for aqueous to highly viscous media. The conical cup-shaped impeller is particularly well-proven for uniform mixing (homogenizing), for admixing additives and for stirring out air bubbles (degassing). Compared to other mixers, the cup stirrer also impresses with a shorter stirring process. In contrast to other stirrers, the cup stirrer enables optimal and gentle mixing by generating sufficient flow even at relatively low speeds. This enables a highly efficient and energy-saving stirring process despite a very low peripheral speed. This results in various process-related advantages such as the very low formation of drums, hardly any air entry and foam formation. The shear transferred into the medium is also very low with the cup agitator. For IBC containers and other containers with a small top opening, folding cup stirrers are a specifically well-suited option. A foldable cup stirrer opens automatically due to the centrifugal force during the mixing process. During the installation and the removal of the stirrer, the cup elements are folded and hence require little space.

Cup stirrer with 3 conical cups as impeller element
Behälter KG offers brand new cup stirrers as IBC-container agitators, tripod agitators, as well as installed in our mixing tanks SDE-Flexmix (550-1150 liters), AIT-Containermix (1000 liters) and FIT-Storemix (800-20,000 liters).
We also have selection of high quality second-hand stainless-steel tanks with cup stirrer immediately available from stock.
Proven agitator for aqueous to medium-viscosity media.
The oblique blade stirrer (also called cross blade or inclined blade stirrer) features a multi-bladed impeller, consisting of usually four (sometimes up to eight) stirrer blades, arranged at a 45 ° angle. This results in both axial and radial flow. The oblique blade stirrer convinces by a higher energy input and a more shear force than, for example, a propeller stirrer. This results in more turbulent mixing and a higher flow rate.

Strong agitator with high shear for dispersing.
The dissolver, also known as toothed disk stirrer, is mainly used in the paint and varnish industry for dispersion, emulsification, and wet grinding at high speed. The dissolver's toothed stirring disc generates high shear forces during the mixing process, which can break up the finest particles. Due to the special shape, the dissolver disc makes a high energy input. However, since this stirrer has a relatively low flow rate, other stirring tasks are only insufficiently solved. That is why Behälter KG is happy to offer you dissolver agitators in combination with other agitators, for example together with an anchor agitator and / or cup stirrer.

We also offer an extensive range of premium used stainless steel tanks with dissolver agitator, immediately available from stock.
Versatile agitator based on innovative rotor-stator technology.
The rotor-stator technology creates a strong axial beam that mixes the entire content of the vessel quickly and without any air intake. There is also no vortex formation and no sedimentation inside the vessel. The jet stream agitator can be installed centrally on the top bottom as well as laterally in the cylinder of the mixing tank.

For sterile applications in the low-viscosity range and for small batch sizes.
Magnetic stirrers are ideal for sterile and hygienic applications, especially in pharmaceutical applications. The torque transmission of a magnetic stirrer takes place through a magnetic field. This means that there is no need to provide a shaft feedthrough in the mixing tank, which offers great hygienic advantages. The magnetic stirrer is installed in the bottom of the vessel, so that the homogenization of the product is guaranteed even with at the smallest filling quantities. In addition, most magnetic agitators are optimally suitable for usage in vacuum or pressure vessels.
