5.13 Prime the pump with an ejector

On suction lift installations, you can prime the pump using an ejector to remove air from the casing and
suction line. The ejector can be operated by steam, compressed air, or water under pressure.
1. Connect the ejector to the tapped opening in the top of the pump casing.
2. Close the discharge gate valve and open valve E in the steam, air, or water pressure supply line.
3. Open valve S in the suction pipe of the ejector connected to the pump casing.
Air will be evacuated and liquid will be drawn up into the suction pipe and pump casing.
4. When all air is evacuated, do the following:
a) Start the pump.
b) Close valve S and valve E.
c) Open the discharge gate valve.
