What are propeller agitators?

Propeller agitators are advanced mixing systems that use rotating propellers to move liquids. These agitators are particularly suitable for applications requiring high mixing speeds at low to medium viscosities. They operate with an axial flow that ensures uniform distribution of liquids and allows for highly effective mixing of media.

Stainless steel propeller agitators offer numerous advantages, making them indispensable in industries such as chemicals, pharmaceuticals, food production, or water treatment. For a comparison with other common types of agitators, we recommend this article, in which we provide an overview of all common agitator systems.

Advantages of stainless steel propeller agitators

• High mixing efficiency: Thanks to their design and high recirculation rate, propeller agitators achieve uniform distribution of liquids in the tank.
• Low power consumption: Propeller agitators require less energy than other types of agitators, helping reduce operating costs.
• Continuous operation possible: Propeller agitators are suitable for continuous operation, provided regular maintenance is performed.
• Versatile use: Our propeller agitators are suitable for a wide range of applications, from intensive mixing to transporting liquids over long distances.
• Cost-effective to purchase: High-speed propeller agitators with direct drive and approx. 1500 rpm are inexpensive to purchase because no costly geared motor is required.
• Easy maintenance and cleaning: Stainless steel agitators are particularly easy to clean and maintain, which is especially beneficial in the food and pharmaceutical industries.

Technical features of propeller agitators

Most propeller agitators are equipped with modern rotor blade designs that guarantee high thrust and efficient energy use. Typical features include:

• Rotor diameter and blade angle: Adapted to the specific requirements of the mixing task for optimal mixing and low energy input.
• Material selection: Stainless steel AISI 304 or AISI 316, depending on the application and corrosion resistance requirements.
• Mounting options: Direct mounting on a mixing tank, mounting on a bridge or on a lifting stand.
• Rotational speeds: Adjustable speeds (e.g. 300 - 1500 rpm) to control the mixing speed depending on the medium's viscosity.

Propeller agitators for various mixing tasks

Propeller mixers are ideal for processing liquid media with low viscosity levels, e.g. up to 600 mPas. In this range, propeller agitators can handle a variety of mixing tasks. They are particularly effective at mixing:

• Liquids with low viscosity
• Suspensions
• Homogenizing mixtures

Buy new and used propeller agitators from stock

At Behaelter KG we offer both new and used propeller agitators that we can ship directly from stock without lead times. Used propeller agitators and mixing tanks with propeller mixers are significantly cheaper to purchase than comparable new tanks and are therefore an attractive alternative to new construction with longer delivery times. What we offer:

• Wide range: We offer a large selection of propeller agitators perfectly tailored to your individual needs.
• Consulting and expertise: Our many years of experience in mixing technology and tank construction allow us to provide customized solutions.
• Quality and reliability: We only carry high-quality products designed to meet the needs of the most demanding industries.

Our sales team is happy to help you find the perfect solution for your production processes – whether for industrial applications in the food, pharmaceutical or chemical sectors, or for pilot applications in research and development.
