2 Product Description
2.1 Intended Use
Maier Rotary Joints are only permitted to be used as fittings to connect pressurized pipes to rotating pressurized
systems. Typical examples of such rotating pressurized systems are rollers which are heated or cooled by means
of liquid, gas, or steam flowing through them. Please refer to the section "Specifications and Spare Parts" for
details on approved media, their grades and specifications. These specifications must be observed in the
application. Other media may be possible; please consult the manufacturer.
Never modify the rotary joint as this can cause hazards. Install, operate and maintain the rotary joint only as
described in these operating instructions. Company Maier will not be liable for any damages and operational
disruptions resulting from failure to read and/or observe the operating instructions.
These operating instructions do not contain all the information which is crucial for safe operation. In addition,
you are required to observe all national and local laws and regulations concerning the prevention of accidents,
applicable at the place of installation.
For repairs, use only genuine Maier spare parts or standardized components explicitly approved by Maier. Using
any other components can have adverse effects on the safety of the unit.
2.2 Reasonably Foreseeable Misuse
In case of reasonably foreseeable misuse of the product, the manufacturer's warranty will be void and the
operator will be fully responsible for the consequences.
Reasonably foreseeable misuse includes:
 failure to observe the application data
 failure to observe the medium specifications
 failure to observe the maintenance intervals
 failure to replace wearing parts
 failure to perform maintenance work
 faulty maintenance work
 additional components mounted and conversions carried out without written approval
 use of non-genuine spare parts
