Gas sampling and gas conditioning technology 6-1.1.15-ME
11.3 PNEUMATIC
N O T E !
Components connected to the pump must be designed according to the
pneumatic performance of the pump (see technical data).
The pump must only be used in the conditions specified in the technical
data.
 Remove the protection plugs from the port threads (thread size G1/4”).

Accessories like temperature resistant hose connections are screwed into the port threads by
sealing tape.

Connect the suction and pressure heated lines.
12 SUPPLY LINE CONNECTIONS
12.1 HOSE-/TUBE CONNECTIONS
The gas inlet and outlet hoses/tubes are connected on the top of the pump. Standard G 1/4" threaded
joints are available for the connection of the gas sample lines.
N O T E !
The valve body must be fixed while mounting the fittings because moving
may change the pump capacity.
Do not confuse hose-/tube connections for sample gas inlet and outlet; the
connections are labelled accordingly !
Check for tightness of all sample lines after connection!
The tightness of the connections can only be guaranteed if the end section
of the connection hose/tube is flat (use a hose-cutter)!
When connecting the sample gas supply hoses or tubes to the corresponding threaded connections,
pay attention to the following points:

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 mounted 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 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.
The appropriate tube or hose threaded joint connections are available optionally from M&C.
