Description of the Product
SKS (catchment chamber system) requires a sealing medium to retain proper function.
The purpose of the sealing medium is to divert heat that is generated and to prevent the
medium being sealed off (on the pump side) to a great extent from entering into the sealing
gap. The sealing medium completely fills up the space between the product and
atmosphere-side GLRD.
7.5
System with sealing pressure (SK)
Commissioning and safe operation
In this SKS (catchment chamber system) the arrangement of the GLRD (mechanical seal)
is "Back to Back". The function of this double-action GLRD is only ensured if the catchment
chamber is completely filled with clean sealing medium.

Caution!
Before commissioning the pump unit, make certain the catchment chamber is
filled with clean sealing medium.
Caution!
The pump unit was delivered with the catchment chamber empty. Due to the
factory approval, however, the inside surfaces of the catchment chamber are
wetted with oil. If the sealing medium is not compatible with mineral oil, the
catchment chamber should be rinsed with a solvent before filling.
