The SDE Flexmix is suitable as mobile mixing tank for all industries and applications. Due to the two large hinged lids, the tank can always be easily serviced and cleaned. As the inside of the tank is mirror polished and has a very low surface roughness (Ra < 0,2 µm), the mixing tank has been designed for the highest hygienic standards.
Thanks to the versatile available stirring technology, the mixing tank can also be converted universally for different purposes. For every tank, we provide the respective CE marking, declaration of conformity, assembly and operating instructions. Proven Behälter KG quality since 1965.
The container can be moved flexibly with the forklift or pallet truck
Thermoplate double jacket on the cylinder of the container
How is the heating / cooling jacket operated?
The optional Thermoplate double jacket of the SDE Flexmix is welded onto the cylinder of the tank. The jacket has an operating pressure of +5 bar and is equipped with two R1“ connections for the inlet and outlet of the temperature control medium. The tank is designed for cooling with ice water or glycol or for heating with warm water or thermal oil (max. 80 °C). Please note that the Thermoplate jacket must be connected to an on-site heating / cooling source that is not included in the scope of delivery. Alternatively, we also offer an electric heating jacket for the SDE Flexmix, contact our sales department for additional information.
Which agitator technology can be installed on the SDE Flexmix?
We offer you the appropriate agitator technology for all stirring tasks and viscosity levels. For the SDE Flexmix, we recommend the following agitator types, which we usually offer directly from stock:
High-speed propeller agitator: With the high-speed propeller agitator, low-viscosity media can be homogenized turbulently. The speed ranges up to 1500 rpm but can be reduced through the integrated frequency inverter. Inexpensive design, as no gearbox is built in. Designed for media up to 600 mPas.
Slow-running propeller agitator: With a slow-running propeller agitator, low-viscosity media can be gently homogenized, e.g. dairy products. The lower speed is made possible by a high-quality gearbox. The speed ranges up to 250 rpm but can be variably reduced through the integrated frequency inverter. Designed for media up to 1000 mPas.
Blade agitator: With the blade agitator, both aqueous and medium-viscosity media can be mixed efficiently and gently, at a variable speed of up to 62 rpm. The two eccentrically positioned blade elements ensure a high circumferential speed due to the large diameter. Designed for media up to 5000 mPas.
Cup stirrer: The cone-shaped cup stirrer is ideally suited for gentle homogenization and degassing of demanding media. Centrally positioned on the flat traverse lid, the cup stirrer ensures gentle and efficient mixing even at low speeds of up to 190 rpm by generating enough flow. This leads to an energy-saving stirring process despite a very low circumferential speed. Several process-related advantages are the result: a very low vortex formation, no air-intake into the product and no foam formation. The shear forces transferred into the medium are also very low with a cup stirrer. Proven areas of application for the cup stirrer include uniform mixing (homogenizing), admixing of additives as well as eliminating air bubbles inside the product (degassing). Designed for media up to 3000 mPas.
Dissolver: The dissolver is our most powerful standard agitator and is therefore supplied with a 4.0 kW motor. At a high speed of 1400 rpm, it can be used for dispersion, emulsification, solid and wet grinding. The dissolver's toothed stirring disc generates high shear forces during the mixing process, which can break up the finest particles. Due to its specific shape, the dissolver disc makes generates a substantial energy input into the product. The dissolver agitator is not equipped with a frequency converter as standard but can be offered with an external converter upon request. Designed for media up to 3000 mPas.
Anchor agitator (grid agitator / cream mixer): Viscous media such as honey or glue can be gently mixed with the anchor agitator. Installed centrally on the flat traverse lid, the massive anchor agitator element ensures a high circumferential speed at a variable speed of 0 - 12 rpm. Due to the continuous stirring process very near to the bottom and cylindrical part of the tank, the anchor stirrer is also ideal for efficient heat transfer. Teflon wipers can be optionally installed for the anchor agitator. Designed for media up to 10000 mPas.
Jet-stream mixer: At a high speed of 1400 rpm, the jet-stream mixer enables efficient mixing with a short stirring time thanks to its innovative rotor-stator technology. Additional advantages are the elimination of sedimentation and air-bubbles inside the product. Designed for media up to 800 mPas.

Can the SDE tank also be used without agitator?
Due to its functional and mobile design, the SDE Flexmix stainless steel tank can be used as an inexpensive production and storage tank also without agitator technology. Equipped with a flat traverse cover including two large hinged lids, an economical slip-lid or simply as an open storage vessel without a cover, the SDE tank can be used in a variety of ways.
Simply choose your preferred stand form: either our forklift-ready polyethylene base (tested and proven for many years) or, alternatively at an additional cost, positioned on two fixed and two guided wheels. Of course, we also have suitable outlet fittings for the DN50 DIN11851 outlet, that we can supply you with.
Can also be purchased as an open tank with a slip lid
Delivered ready to plug in, with contact switches for the two hinged covers
