4 Transportation and Storage
Transportation
 Use suitable lifting gear to transport rotary joints weighing more than 25 kg.
Storage

Maier rotary joints are not suited for storage in the original package for more than 6
months.
 For periods of extended shutdown or storage of the rotary joints, it is recommended to
use a suitable corrosion protection sheet as provided, for example, by Cortec Corp.
(www.CortecVCI.com).

The storage room must be free from dust, sufficiently ventilated and not subject to ma-
jor temperature changes (relative humidity below 65%, temperature between 15°C and
30°C).

After a storage time of more than 2 years or when the package has been damaged or
the unit has been subjected to shocks, the rotary joint must be checked in the factory or
the nearest service center!
 If you want to preserve complete system components with the rotary joint attached,
make sure the corrosion protection measures are compatible with the materials and
sealing elements used. Otherwise there is the risk of chemical reactions and deposits at
sealing and bearing elements.
5 Information on Mounting and Operation
The following has to be observed to ensure fast and reliable mounting, commissioning, and
safe operation of the rotary joint otherwise any warranty claims will be void:

Never operate the rotary joint outside of the specified application and performance lim-
its.
 Smooth operation of the rotary joint is only possible if roller and intermediate flange are
concentric and do not wobble!

The information on the admissible mounting position of the rotary joint provided in the
section "Specifications and Spare Parts" must be adhered to.

Use flexible hoses to connect pipelines with the rotary joint housing. This compensates
for heat expansion and vibrations.

Never apply torsional, tensile or pressure loads to metal hoses. Observe the minimum
bending radii specified by the manufacturer – if in doubt, contact your hose vendor.
Section 6.2 provides examples of possible hose routings and installations.
Never use axial compensators.

Use flat packings made of pure graphite to securely seal flange connections.
 Only operate the rotary joint with a sufficiently dimensioned anti-rotation device at-
tached to the housing. The anti-rotation device must allow for axial and radial move-
ments of the housing. Please refer to chapter 6.3.1 for additional information.
