4.4 Rotostat E
Brief description
Rotostat E are rotary feedthrough with gap seals
for the transfer of fluids during medium pressures
and medium speeds.
The sealing between the stationary and rotating
parts is done via a patented, hydro-static con-
trolled "Floating sleeve". These "Floating sleeves"
are movable arranged. The hydro-static forces
centre the "Floating sleeve" on the rotating shaft.
Even during high speeds and pressures, only vis-
cose friction occurs and therefore only a small, cal-
culated heat formation. The heat is dissipated via
the inherent occurring leak. The leakage losses
are in a small, pre-calculable limits.

4.5 Rotostat N
Brief description
Rotostat N are rotary feedthrough with gap seals
for the transfer of fluids during medium pressures
and high speeds.
The seals in-between stationary and rotating parts
is done via the seal gap, which are kept at their
default value via a patented hydro-static control
mechanism that allows a tumble and irregular run-
ning of the shaft.
Even during high speeds and pressures, only vis-
cose friction occurs and therefore only a small, cal-
culated heat formation. The heat is dissipated via
the inherent occurring leak. The leakage losses
are in a small, pre-calculable limits.
Rotostat N is not subject to temperature fluctua-
tions and pressure impacts due to its design.
