Take note of the following information when you connect the pump to your vacuum system.
z
To minimise noise and exhaust emissions, it is recommended that the primary pump backing the XDS100B is
connected to an exhaust line or a silencer (refer to
z
For optimum pumping speeds, ensure that the pipeline connected to the pump inlet is as short as possible
and has a suitable internal diameter. Also ensure a suitable backing pump is used, such as the XDS35i or
XDS46i, and the connection between booster and backing pump is as short as possible with a suitable internal
diameter.
z
Support the vacuum pipeline to prevent loading of the coupling joints. If necessary, incorporate flexible
bellows in your system pipelines to reduce the transmission of vibration and to prevent loading of the
coupling joints.
z
If the booster and its backing pump are operated with the exhaust line blocked, a pressure of 5.5 bar(a) may
be generated in the exhaust pipework. Foreline pressure may reach 1.45 bar(a). Connect the pump using
appropriate pipework and fittings.
z
Incorporate an inlet isolation valve in the pipeline from the vacuum system to the booster pump and to the
primary pump. These will enable the vacuum system, so that you can isolate the vacuum system from the
pump when it is switched off and prevent the suckback of process gases and debris into the vacuum system.
z
Ensure that the sealing surfaces are clean and scratch-free.
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.
3.7
Leak test the system
After you have installed the XDS pump, leak test the system and seal any leaks found.
