Rotary union (steam, hot oil)
DN 50 - 300, PN 40 | DA series
MAIER
* Inexpensive design, since there are not bearings.
* Available in large sizes, up to DN 300 mm. Nominal bore.
* Seal rings are resistant to fraction, even at high pressures.
* The design A2 for rotating inner pipe has a seal between inlet and outlet.
* Maintenance free - no lubrication necessary.
# Housing made of cast iron with spheroidal graphite, diameters DN 80 and above made of steel.
# Rotor made of chrome steel, rotor pipe for diameters DN 65 and above made of steel; sealing surface made of chrome steel.
# Cover, flange cover, butting ring, adjustment ring and compression springs made of chrome steel.
# Sealing elements made of highly wear-resistant, metal-impregnated artificial carbon. Sealing ring is pressure-loaded.
# The seal requires little maintenance. Wear indicator for sealing ring on rotor. Wear of second ring is determined by means of measurement gauge.
# Connection to rotating pressure system by means of:
- K flange with conical inner ring.
