M&C recommends to mechanically decouple the pump from the piping system, e.g., by using
flexible tubes or hoses. In this way, possible vibrations and noise from the pump can be avoided
being transmitted to the system.
12.4.1 CONNECTING THE PUMP
The pneumatic connection to the diaphragm pump is located on the top of the pump head. Standard
connections with G1/4" female thread are available for this purpose.
A marking on the pump head indicates the flow direction.

Caution
Mixing up the suction and pressure sides can lead to breakage of con-
nected components on the suction and pressure sides.
1. Remove the protection plugs from the port threads (thread size G 1/4” female).
2. Connect the suction and pressure lines.
Note
Accessories such as tube fittings are screwed into the connection
threads with sealing tape (no sealing tape is required when using M&C
fittings).
3. Lay the suction and discharge lines in a downward slope so that no condensate can get into
the pump.
12.4.2 OPTIONAL TUBE FITTINGS
Note
Do not mix up tube connections for sample gas inlet and outlet; the
connections are marked accordingly. After connecting all lines, check
for leaks.
The tightness of the connection can only be guaranteed if the connec-
tion hose has a straight end edge (use a hose cutter).
