Agitators for the pharmaceutical and food industries often require a hermetic sealing solution to ensure that valuable and sensitive products remain safely within the system, and, in particular, to protect them against contamination from the outside. The cleanability of the tank is another 6 primary design focus.

The challenge for magnetic couplings used to seal top entry arrangements is the shaft bearing, as there is no medium available to lubricate the bearings. This means Product variants / operating rangeSMAK © EagleBurgmannItem Description that slide bearings cannot be used, and roller bearing have SMAK4-75-4/40 1.1 Inner rotor lots of gaps and dead spaces that are difficult to clean Max. torque 16 Nm 1.2 Outer rotor without special tools.

4 Cleaning / sterilization After the production process, the entire agitator is generally cleaned. The bearing area, and inside of the SMAK are not directly accessible, but can easily be cleaned, or sterilized via the purging connection.

From the connection (1), the fluid enters the annular duct (2), and from there it passes through the holes (3) into the space between outer magnetic rotor and can. The Flow of cleaning fluid then flows through the bearing area (4), cleaning fluid emerging into the agitator tank.

SMAK Spülung © EagleBurgmann Important note All the technical specifications are based on extensive tests and our many years of experience. However, the diversity of possible applications means that they can serve as guide values only.

It should be noted that the extremal values of each operating parameter cannot be applied at the same time because of their interaction. Furthermore, the operating range of each specific product depends on the respective shaft diameter, materials used, mode of operation and on the medium to be sealed.

A guarantee can only be given in the individual case if the exact conditions of application are known and these are confirmed in a special agreement. When critical conditions of operation are involved, we recommend consulting with our specialist engineers. Subject to change.
