Vacuum connection (inlet)
Inlet: Small flange connection KF DN 25 with clamping
ring and centring ring.
Connect the vacuum line (e.g., metal hose (stainless steel)
KF DN 25) at the inlet of the pump.
• Reduce the transmission of vibration. Pre-
vent mechanical load due to rigid pipelines.
Insert elastic hoses or flexible elements
as couplings between the pump and rigid
pipes.
Note: Flexible elements will compress or
flatten when evacuated if not designed for
use under vacuum.
• Hose connections at the pump inlet must al-
ways be gas tight.
Use a suitable adapter to connect a vacuum
hose (caoutchouc) 15 mm ID (see “Accesso-
ries / Spare parts”, pg. 92), if necessary.
inlet
Use connecting hoses with large diameter and
keep them as short as possible to avoid flow
losses. Locate the pump as closely as possi-
ble to the application.
Secure hose connections at the pump ap-
propriately, e.g., with hose clamps, to protect
against accidental detachment.
