Other parameters of the medium:
Partially desalinated water with conductivity >80 μs, silicates <10 mg/l, pH-value >9, heating wa-
ter with conductivity <850 μs, silicates <10 mg/l, solids content <10 mg/l, cooling brine, inorganic;
pH-value >7.5, inhibited, water with oil pollution, cooling water with antifreezer (pH-value: 7.5-10; no
galvanised components), water-glycol mix (20%-40% glycol)
Use of solvents is not admissible, as the elastomers of the seals may be attacked. This may
result in uncontrolled leakage!
CAUTION! The self-heating of the seal material combination used adds up to about 35 °C
during normal operation at maximum permissible ambient temperatures of 40 °C.
The specified rotating unions are designed for hazardous areas.
The rotating unions of the series 54, 55 and 57 can be used as one-way or two-way version depending
on the type of connection.
