When
operating the pump as a compres-
sor, check that the system which you are
going to pressurize is mechanically stable.
Check that the maximum generated over-
pressure is compatible with the mechanical
stability of the pressure vessel. Do not gen-
erate overpressure in vessels other than in
those designed for that purpose.
Risk of
bursting!
Install an additional overpressure safety re-
lief device in the pressure system, if neces-
sary.

Especially when using the pump as vacu-
um pump provide a free and pressureless
exhaust outlet to avoid damage to pump
valves and risk of bursting.
• Reduce the transmission of vibration. Prevent mechan-
ical load due to rigid pipelines. Insert elastic hoses or
flexible elements as couplings between the pump and
rigid pipes.
Secure hose connections at the pump ap-
propriately, e.g., with hose clamps, to protect
against accidental detachment.
To reduce pump noise emanating from the pump
exhaust port (ME 4R NT / MD 4S NT), connect
an exhaust hose or use a silencer (see “Acces-
