Weight classes
Buckets are sorted by weight. The weight class is embossed into the side of the groove, see illustration:
e.g.. "_60" (the last 2 digits in grammes if the empty bucket weighs 260 g, for example).
Then place all buckets on a scale, consecutively if possible, and check for deviations.
In this example "60", the weight must be between 260 g and 260.9 g with empty and cleaned
rectangular buckets A-4-44.
Opposing buckets in the rotor must be of the same weight class.
Note: a mixed arrangement of 2 opposing MTP carriers with 2 rectangular buckets or 2 Flex
buckets is permitted only on swing-bucket rotor A-4-81
Use with only two buckets inserted is prohibited for all swing-bucket rotors!
Supplementary information for MTP/DWP/Flex buckets
Are the side walls bent as a result of too many plates or the wrong, non-approved plates having been
inserted? The cause may also be a plate inserted carelessly at the edge of the bucket.
Under no circumstances continue using buckets with bent side walls.
Watch out for deformation.
If the baseplate is damaged or cracked or the screws are oxidized as a result of aggressive chemicals or
inadequate cleaning, then replace them. In the process, replace plastic baseplates on all buckets with
rubber baseplates.
Information: to replace the rubber baseplate: undo screws, remove baseplate and clean bucket. Ensure
that the new rubber baseplate is located centrally. Do not use any adhesive such as Loctite or similar;
gently tighten new screws alternately to 0.6 Nm so that no unnecessary deformation is caused.
Fixed-angle rotors
Examine the bores of the fixed-angle rotor. Are there any cracks, changes inside or underneath the
rotor? Perform the examination using the torch (or endoscope, if appropriate). Any residues of chemicals
or the like will have to be removed for this purpose. Is there visible efflorescence/are there visible
material changes at the edge of the rotor under the seal?
This is often caused by the customer not taking adequate care of the rotor.
