●
If necessary, loosen the hexagonal nuts of the gland follower and re-
tighten until hand-tight.
●
Allow the device start without or with a low pressure load (jog mode).
○
Flow should have developed after 30 s at the latest.
○
Monitor the gland packing temperature.
●
Run the device for a few minutes depressurised or with low pressure.
●
Vent the system at the highest possible point.
●
Gradually increase the pressure load up to the desired operating pres-
sure.
●
Adjust the gland packing step by step until the required amount of leak-
age is obtained.
●
Operate the system for so long until the final operating state is achieved.
●
Check the operating data such as:
○
Discharge flow
○
Amount of leakage
○
Operating pressure (as close as possible to device)
○
Fluid temperature (as close as possible to device)
○
Device temperature (in particular in the area of the bearing points)
The temperatures determined on the device surface should be a
maximum of 20 °C above the media temperature.
○
...
●
Document the operating data of the initial start-up for later comparison.
●
Check the level of the operating medium in the system.
●
Check the filling level of the liquid seal (if existing).
●
Check the device for leaks.
●
Check all threaded connections for leaks and retighten if necessary.
In order to ensure a constant and reliable function of the device, an initial
maintenance of the device is recommended after several hours warm-up
time (max. 24 h). Faults can thus be identified at an early stage.
