Advantages of the agitator design

Safe and reliable operation
as a result of high permitted overhung loads

No additional bearing requirements for the agitator shaft,
which means a simpler design and a more economical end result

Versatile combination options,
as shaft and flange dimensions are compatible with standard market dimensions

Also flexible for your agitator,
with many options and design variants available for the gear unit

Available 24/7,
because the global SEW‑EURODRIVE service team is never far away

Easily optimized – extremely versatile

SEW-EURODRIVE covers virtually every application in a wide variety of industries with the special agitator design used in three highly successful standard gear unit series. The RM.. series of helical gear units from SEW‑EURODRIVE has long been available as an option for mixer and agitator applications.

NEW to the portfolio are the FM../FAM.. series of parallel-shaft helical gear units and the KM../KAM.. series of helical-bevel gear units – the two types of gear unit often used for such applications. On the one hand, these variants enable better use to be made of the available space, while on the other, agitator shafts with a mixing element can be inserted directly into the hollow gear unit shafts in the portfolio. Additional bearings can be dispensed with in many cases.

The permissible overhung loads range from 25 000 N to 176 500 N and the motors corresponding with the relevant sizes vary in power from 0.12 kW to 200 kW. The maximum permitted gear unit output torque ranges from 820 Nm to 20 000 Nm.

More information about gearmotors in agitator designs can be found here.

The following options are available for the agitator design:

  • Double oil seal on the output side for additional protection against leaks
  • Reinforced bearings, also opposite the output side, to increase the permitted overhung load, particularly in the case of high output speeds and low gear ratios
  • Grease nipple for relubrication of output shaft bearings
  • Drywell design with leak sensor to prevent the product from being contaminated by leaking lubricant

Compatible motors

It goes without saying that SEW‑EURODRIVE also offers motors in energy efficiency classes IE1 to IE3 that are compatible with these gear unit designs.

X agitator drives with extended bearing distance

The X agitator drives from SEW‑EURODRIVE can be used wherever a high level of performance is required for stirring and mixing large quantities of liquid or paste-type substances, for example in the chemical industry, the food industry, wastewater treatment or mining.

X series agitator drives have been designed for application-specific loads:

  • For light loads :
    A model with a universal housing for helical gear units and helical-bevel gear units (2- to 4-stage) is available for the torque range between 6.8 and 475 kNm.
  • For medium and heavy loads :
    Two models featuring a rolling bearing design with increased bearing distances are available in the 22 to 90 kNm torque range. It goes without saying that all of our drives are suitable for use in ATEX scenarios and can be combined with the standard options of drywell sealing, pressure lubrication / bath lubrication, flange coupling, fan cooling and foot or flange mounting.
    • The first model is available exclusively as a 3-stage helical gear unit. The maximum thermal rating of this model has been significantly increased thanks to the use of an optimized vertical housing with cooling fins and axial fans.
    • The second model is available as 2- to 4-stage helical gear units and bevel-helical gear units. It is based on the combination of a universal housing and a reinforced bearing design.
