4.8 Connect the pump inlet
Take note of the following informaon when connecng the pump to the vacuum
system. Refer to Accessories on page 46 for details of the accessories menoned below.
▪ For opmum pumping speeds, ensure that the pipeline connected to the inlet-port
is as short as possible and has an internal diameter not less than the inlet-port
diameter.
▪
Support the vacuum pipelines to prevent loading of the coupling-joints.
▪
If necessary, incorporate exible bellows in the system pipelines to reduce the
transmission of vibraon and to prevent loading of coupling-joints. If you are using
exible bellows, ensure that bellows are used which have a maximum pressure
rang which is greater than the highest pressure that can be generated in the
system. It is recommended that manufacturers exible bellows are used.
▪
Use a suitable inlet catchpot if pumping condensible vapours or if using the pump
for very dusty applicaons.
▪
Ensure that sealing surfaces are clean and scratch-free.
Connect the vacuum system to the inlet-port (Figure: General view of the pump on page
11). To make this connecon:
▪ Connect to the NW25 ange supplied: use the NW25 centring-ring and O-ring
supplied.
▪
Remove the NW25 ange and connect to the 1 inch BSP threaded hole.
▪
Use an NW25 to 28 mm bore tube adaptor available as an oponal accessory, refer
to Pump inlet adaptor on page 48.
