3.9 Connect the pump-outlet
We recommend that you use an exhaust extraction-system suitable for use with all of the process
gases you will pump. Ensure that the exhaust-extraction system cannot become blocked or
obstructed when the pump is operating.
Use standard NW fittings to connect the pump-outlet to the exhaust-extraction system: refer to
Section 2.1 for the outlet sizes.
Note that the ESDP12 pump is supplied with the flange face of the outlet (Figure 1, item 10)
towards the front of the pump. If required, you can turn the outlet through a maximum of 90
o
towards each side of the pump. If you want to reorientate the outlet, use the following
procedure:
1. Refer to detail A. Loosen the locknut (13).
2. Turn the outlet (10) to the required orientation.
3. Tighten the locknut (13).
3.10 Leak test the pump installation
Leak test the pump installation and seal any leaks found to prevent the leakage of dangerous
substances from the system and the leakage of air into the system. When supplied, the leak
tightness of the pump is less than 1 x 10
