Universal rotary joint for rotating inside ring up to 3500 U/min, up to PN 50

Suitable: Rotary joint for combined supply and drainage. The inner tube can be tightly bound to the drum which the medium is being supplied and when rotating can take over the drainage of the supplied medium. The stand pipe is inserted in a H7-fit in the rotary joint, which guarantees the rotational function.These rotary joints are suited for use of non-contaminated water, heat transfer oil and saturated steam (intermittent). Alternatively, the units can be equipped with a special seal for aggressive, abrasive media and contaminated water.
Advantages: The springs are external to the media flow in order to minimise the loss of pressure and avoid turbulence.
Materials: Housing: Brass, optional: stainless steel, seal: Carbon graphite / Tungsten carbide
Temperature range: Water up to max. +175°C, saturated steam up to max. +140°C, heat-transfer oil up to max. +200°C
Operating pressure: Water: G 3/8" to G 1 1/2" max. 50 bar, G 2" max. 40 bar Saturated steam: max. 3 bar, heat transfer oil: max. 6.5 bar
Optional: Version in stainless steel -ES, seal package for abrasive media or unclean water -AB
Warning: Maximum pressure and speed values may not occur simultaneously. If in doubt, please ask us for confirmation. A fluid pressure of over 8 bar is only permitted when used with cooling water and a maximum temperature of +50°C. For heat transfer oil with temperatures over +175°C, the speed may not exceed 300 rpm. For reverse operation, shafts with flanges are to be used.
Warning: Take note of left and right-handed threads. Left-handed thread for feeding into clockwise rotating drums. Right-handed thread for feeding into counter-clockwise rotating drums.
