8.8
Installation of SIHIdry Vacuum Pump into Pipework
The pump must be aligned with the pipework. Remove the caps from the flanges only shortly before
connecting the pipelines to avoid ingress of foreign material. The pipework must be laid in such a way
that thermal expansion in the pipe system does not generate additional forces on the pump flanges The
suction line has to be connected carefully (vacuum-tight – any leakages on the vacuum side will reduce
suction capacity performance).
8.9
Electrical Connection
Provide cables with adequate protection [local regulations and safety codes must be applied] to avoid
any danger of mechanical damage. When laying outdoors use weather-resistant cables.
8.10 Final Checklist
The following final checks must be carried out:
1. Check the pump set is leak tight.
2.
Check the supply of sealing and instrument gas and the coolant.
3.
Check the tightness of the flange connections.
4. Check the electrical connections.
8.11 Vacuum Pressure Test
When subjecting the piping system to a vacuum pressure test it must be ensured that the pump is
isolated from the system. There must not be any liquid in the pump or flowing through the pump. The
leak test of the SIHIdry
has to be carried out under vacuum.
