Running-in time of the floating ring seal
The sealing surfaces of the floating ring seal are lubricated by the pumped medium, so that a cer-
tain leakage flow is always to be expected which exits the floating ring seal.
After commissioning the pump for the first time or when a new floating ring seal has been installed,
a certain running-in period is required before the leakage rate drops to an acceptable level. The
required running-in period depends on the operating conditions. This means that every time the
operating conditions change, a new running-in period begins.
Under normal operating conditions, the leakage fluid evaporates. Therefore, the leakage is not

Prior to this, the pump must be installed and
the system filled. The system pressure must be
applied. Then proceed as follows:
1. Loosen the union piece of the capillary
tubes from the suction and pressure con-
nection, but do not remove it completely.
2. Wait until the medium flows out continuous-
ly.
3. Retighten the union piece manually.
