For systems with sealing pressure, constant circulation of sealing fluid must be ensured to
provide safe and reliable operation. The sealing fluid must flow through the sealing space
from bottom to top. We recommend placing the outlet of the sealing medium at the highest
point on the SKS (catchment chamber system).
Laying lines for the SKS with sealing pressure
When laying pipelines and hoses make certain no high points are created. The connection
lines to the pump must always be laid rising to ensure self venting of the line.
Our connections for sealing fluid have IG R1/4"
The pressure in the catchment chamber must always be 1-2 bar higher than the pressure
in the pump so that the two seals only have to seal off the neutral sealing fluid. We
recommend installing a pressure gauge to monitor pressure. The flow rate must be
regulated so that the temperature of the sealing medium at the outlet is less than 60°C. The
temperature difference between the intake and outlet must not exceed 15°C. The
temperature of the sealing medium must never exceed the boiling temperature of the
sealing fluid. We recommend monitoring the temperature of the sealing fluid.
The resulting flow rate can be determined by volumetric measurement. Under normal
conditions a continuous rate of at least 3 l/min should be set.
If the stated operating limit data are observed and the instructions given in the manual are
followed, the SKS (catchment chamber system) should operate with no problems.
