7.2.1
Operating fluid: oil
In case of orders without performance data the filling quantity is not entered. In these cases, for operation
with oil the filling quantity for the respective coupling size can be obtained from the filling quantity tables
in section 10, item 10.9 and item 10.10 independently of the speed and output to be transmitted
(and possibly the motor output).
The filling quantity tables in section 10 apply solely to oil fillings.
HL or HLP hydraulic oils to DIN 51524 Part 1 and Part 2 of the VG 22 or VG 32 ISO viscosity classes must
be used as operating fluid.
The oil quality and purity determine the useful life of FLUDEX bearings and
shaft-sealing rings.

Observe manufacturer's instructions when handling the operating fluid.
7.2.2
Operating fluid: water or water emulsion
The coupling must be protected against freezing during standstill.
Observe manufacturer's instructions when handling the operating fluid.
Not every FLUDEX coupling is suitable for use with water or water emulsion as an
operating fluid.
FLUDEX couplings designed for water fillings are marked as follows in the area of the
filling plug (153): "
If water or water emulsion is used as operating fluid, only fusible safety plugs with
a maximum fusing temperature of 110 °C are permitted. At a higher fusing temperature
excessive strain is put on the coupling housing by the operating fluid vapour pressure.
