• 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.
In case, install a small flange connection KF
DN 16 (thread G1/8”) instead, see „Accesso-
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.

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.
• A power failure may cause accidental ventilation of the
pump. If this constitutes a potential source of danger,
take appropriate safety measures.
