ROTOFLUX® Universal series rotary unions, single flow
Product N° S
Helpful information:
Universal series rotary unions are available with two different types of seals (balanced and micro-lapped):
- N (normal seals) graphite vs. tungsten carbide for applications with filtered water, intermittent steam and diathermic oil.
- D (harder seals) tungsten carbide versus tungsten carbide for applications with dirty water and abrasive liquids.
Pressures above 8 BAR are only allowed with water at a maximum temperature of 50°C.
For applications with diathermic oil above 175°C the max. allowed speed is 300 RPM.
Do not use rotary unions in the maximum operating conditions without consulting us.
