Startup; Liquid Filling: H ≤ 1M - Biral ComBo easy Serie Montage- Und Betriebsanleitung

6 Startup

A visual inspection for damage must be performed on all components before
commissioning, especially on the pressure vessel with a membrane lining.
Do not start the pumps until they have been filled with liquid.
When pumping hot liquids, make sure that persons cannot accidentally come
into contact with hot surfaces.
Safety valve:
If the maximum permissible operating pressure is exceeded, steam/liquid esca-
pes via the safety valve.
6.1 Liquid filling: H ≤ 1m
1. Close the isolating valve on the discharge side of the pump.
2. Open the isolating valve in the suction pipe completely before starting the pump.
3. Remove the filling plug.
4. Fill the pump housing and the suction pipe completely with liquid until a steady stream
of liquid runs out of the filling hole.
5. Fit and tighten the filling plug.
6. Slowly open the discharge isolating valve while the pump is running. This ensures venting
and pressure build-up during start-up.
Caution
The discharge valve must be opened immediately after start-up of the pump.
Otherwise the temperature of the pumped liquid may become too high and cause
material damage.
