• 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.
MD 1C + AK + EK:
Assembling the hose nozzle with union nut:
➨
Take the hose nozzle with attached com-
pression ferrule and union nut out of the
catchpot and put onto inlet connection.
➨
Tighten the union nut by hand until you can
feel the stop. Then tighten an additional 1/4
rotation with an open-ended wrench (size
17mm) for final installation.
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.
NOTICE
✘
✔
Secure hose connections at the pump ap-
propriately, e.g., with hose clamps, to protect
against accidental detachment.
NOTICE
+
Particles and dust must not be aspirated. If necessary,
you must install appropriate filters. You must ensure
their suitability concerning gas flow, chemical resis-
tance and resistance to clogging prior to use.
