Filling the seal chamber of the evacuation pump
The seal chamber of the evacuation pump must be filled with the
sealing medium ISO VG 10 … ISO VG 100 before the first
commissioning.
For topping off, use the medium to be purified having a viscosity of ISO
VG 10 … VG 100.
This is needed in order to prevent dry running of the shaft seals.
Dry running of the pump would result in premature wear and tear and
impermissible heating at the sealing lip or dust lip.
This also prevents the ingress of air into the fluid.
Check the fill level of the reservoir (1) at least 1x week and top off as
needed.
