The plug-in shaft connection.
The plug-in connection between the shaft seal and the drive
unit or drive casing makes maintenance work much easier.
For example when
•
replacing rotor and joint parts
•
replacing the plug-in shaft in the sealing area
•
changing from gland packing to mechanical seal
•
replacement of mechanical seals or mechanical seal parts
Faster conversion and replacement
All rotating parts that come into contact with the product
can be dismantled as a single unit. It is simply a matter of push -
ing the splash ring forward on the plug-in shaft, which is
designed as a shaft protection sleeve, and pressing out the
plug-in shaft pin.
The time-consuming dismantling of the complete drive casing
is thereby avoided. The assembly of a new rotating unit is also
fast and easy, thanks to the plug-in connection.
Key advantages
•
Shorter maintenance work due to fast exchange of
rotating parts
•
Higher productivity due to fewer downtimes
