Leakage current
A complex, inverse hydrostatic gap regulator
ensures that even at high pressures, the gap
between stationary and rotating parts are kept at
few μm, so that returning leakage is very low. Due
to its design for stress, the Rotostat N is insensi-
tive to temperature variations, dirt and pressure
impacts.
Models
Rotostat N is available in two models:

n
Emulsions and non-lubricating fluids
4.6 Rotokombi (option)
The Rotokombi design makes it possible to com-
bine the devices with all the manufacturer's other
media feedthroughs. The devices can be com-
bined with additional components for gas, water,
grease and oil for transferring electrical currents
and air. The optimal sealing technology is used for
each medium.
