Gas sampling and gas conditioning technology 6-1.1.7-ME
11.3 PNEUMATICAL CONNECTION

Remove the protection plug from the gas connection thread (thread size G1/4”).

Accessories such as tube connections are screwed into the connection thread by means of a
sealing tape (when using the screw fitting from M&C, no sealing tape is necessary).

Connect the suction and pressure line.

Mount the suction and pressure lines in a way to avoid condensate flowing into the pump.
N O T E !
The diaphragm pump is only to be used under the special conditions
specified in the technical data. Do not place the diaphragm pump near
to heat sources and provide sufficient aeration in order to avoid heat
accumulation.
When mounting the pump outside, it must be installed in a protecting
housing that is frost-protected in winter and sufficiently aerated in
summer. Direct solar radiation must be avoided.
12 SUPPLY CONNECTIONS
12.1 HOSE CONNECTIONS
The connection is made on top of the pump. There are standard connections with G1/4” inside
threads.
N O T E !
Do not twist the valve body when mounting the hose connections be-
cause it can influence the sampling capacity of the pump. Do not inter-
change the hose connections for the sample gas inlet and outlet. The
connections are identified accordingly. After all lines being connected,
check whether the connection is tight.
The tightness of the connection can only be guaranteed if the border of
the connection hose is straight (use a hose cutter).
When connecting the hoses to the hose connection fittings to be supplied as option, please note the
following:

Loosen the sleeve nut of the clamping-ring threaded joint by turning to the left. Take care that
the nut is removed carefully from the body of the threaded joint to avoid losing the clamping
ring which is placed loose in the nut.

Push the sleeve nut over the connection hose/tube.

Push the clamping ring onto the connection hose/tube with the thicker bulge pointing to the
nut.

Push the hose/tube onto the supporting nipple in the threaded joint. Tighten the sleeve nut by
hand.
The hose/tube is now mounted in such a way that it cannot slip and is resistant to pressure.
Connection fittings for DN 4/6 or DN 6/8 are optionally available from M&C.
