The wastewater industry plays a crucial role in maintaining the health and well-being of our environment. Having reliable and efficient systems to manage and treat wastewater is more important than ever. Having the right mixer and agitator drives are key to that.
SEW-EURODRIVE agitator and mixer drives are vital in these critical day-to-day practices. They provide highly versatile and optimised solutions to ensure consistent and effective mixing of substances. SEW-EURODRIVE agitator and mixer drives are suitable for a wide variety of industries. They include biotechnology, pharmaceutical, chemical, food and beverage, environmental technology, paper and cellulose, and the wastewater industry.
SEW-EURODRIVE offers three standard gear unit series. Each has a unique agitator design, making it highly versatile and easily optimised for different applications.
The RM.. series, available as a variant for mixer and agitator applications, has long been in use.
New additions to SEW-EURODRIVE’s agitator drive variants
There are two new additions to the portfolio.
The first is the FM/FAM series, which is available as parallel-shaft helical gear units.
The second is the KM/KAM series, available as helical-bevel gear units.
These gear variants allow for more efficient use of space. The agitator shafts with mixing elements can be inserted directly into the hollow drive shafts. That eliminates the need for additional bearings in many cases.
The permissible overhung loads range from 25,000 N to 176,500 N, with motors suitable for sizes ranging from 0.12 kW to 90 kW. The maximum gear unit output torque is from 820 Nm to 18,000 Nm. The agitator design offers options such as double oil seals for protection against leaks, reinforced bearings, grease nipples, and a dry well design with a leak sensor to prevent contamination.
The agitator design has several advantages, including safe operation due to high permitted overhung loads, no additional bearing required for the agitator shaft, versatile combination options, flexibility for your agitator, and 24/7 service availability through SEW-EURODRIVE Service.
For those Major Jobs:
The X series agitator drives from SEW-EURODRIVE are perfect for applications that require high performance for stirring and mixing large amounts of liquid or paste-like substances. The chemical, food, wastewater treatment, and mining industries would find the most common use for the X series agitator drives.
For light loads, a model featuring universal housing and helical or bevel-helical gear units (2 to 4 stages) is available with a torque range of 6.8 to 475 kNm. Two models are available for medium to heavy loads with a torque range of 22 to 90 kNm. Both models feature increased bearing distances and a rolling bearing design. These drives are suitable for use in ATEX environments. They can be paired with standard options such as drywell seals, pressure/bath lubrication, flange coupling, fan cooling, and foot or flange mounting.
The first model, exclusively available as a 3-stage helical gear unit, has an enhanced thermal rating thanks to its optimised vertical housing with cooling fins and axial fans. The second model combines universal housing with a reinforced bearing design. It is offered as 2 to 4-stage helical or bevel-helical gear units.
