Points to observe during maintenance:
l
Clean all accessible seal grooves before assembling
l
All accessible surfaces, threads and dismantled components shall be cleaned with a suitable cleaning
agent
l
Clean the thread in the shaft and on the locking nut before installing the lock nut again, to prevent
the build-up of microorganisms in the area of the thread (for example, use a small brush and / or
compressed air or pressurised water / cleaning fluid for the blind hole)
l
Check elastomer parts for elasticity and changes in characteristics (e.g. stickiness, roughness,
discolouring, substantial deformation)
l
To assemble elastomer parts in food and beverage applications, use only NSF H1 listed lubricants that
are compatible with the elastomer material. Use as little lubricant as possible.
9.17 Cleaning the pump
Handle substances and materials used correctly, especially when working on lubricating systems and
when cleaning with solvents. For information on cleaning the parts in contact with the pumped fluid, see
See Cleaning and sterilisation on page 22.
9.18 Faults
If an operating fault occurs, switch off the machine and secure it against unintentional start-up.
