DN 40 ISO KF for NS 0070-0160 C
In the case of long exhaust lines the line cross-section should be larger
than the exhaust flange to prevent a drop in the performance of the
vacuum pump. If you have any doubts, contact your Busch
representative.
A silencer (SI) (optional accessory) can be fitted to the pump discharge
to avoid pulsation and sound transmission into the exhaust line.
Cooling water connection
The cooling water is generally connected with a hose.
Connection diameter:
–
cooling water inlet: 3/8'' NPT
–
cooling water outlet: 3/8'' NPT
Nitrogen connection
Connection diameter: 1/4'' NPT
