Application
The bellows pump MP-F is suitable for 100 % oil-free operation of corrosive gases. The construction
and performance of the pump is especially tailored to the requirements of the analysis technique. The
pump is gas tight and its operation is maintenance-free.
All sample contacting parts of the bellows pump MP-F are corrosion resistant. To connect the pump
head to the tubing, the upper part of the pump head is also available in stainless steel (optional).
The pump operates absolutely lubricant free, this prevents the sample gases from any contamination.
Due to a special bellows and valve system, the pump operates maintenance-free and has a long serv-
ice life. The straightforward valve design ensures low maintenance costs.
The pump is available in 230 V or 115 V and in two different pump capacities:
MP-F05 pump capacity 5 Nl/min (approx. 320 Nl/h)
MP-F10 pump capacity 10 Nl/min (approx. 600 Nl/h)
Liter capacity with a counter pressure of -/+ 50 mbar on the vacuum and pressure side.
Option: integrated needle valve to adjust the flow rate in the pump head of the MP F.../R
and/or
Option: stainless steel pump head with NPT thread.
The sample gas line can be connected to the top or the side of the pump head. The pump head also
can be rotated and mounted in 90° steps.
7.1 MP-F05/R and MP-F10/R with integrated needle
To ensure that the needle valve works properly, the output of the pump needs to be operated with at
least 0.1 bar counter pressure.
To adjust the pump capacity, a needle valve used as an internal pump bypass is integrated into the
pump head. The optimized shape of the needle valve, makes it possible to adjust the pump capacity
over a wide range. All parts of the valve, which are in contact with the sample gas, are made out of
PTFE and PVDF. There are no O-rings in the needle valve.

After adjusting the needle valve, the locknut (see position ) needs to be fastening hand-tight with a
wrench. This ensures that the needle valve is gas tight, and avoids accidental misalignment of the valve.
Warning
Bellows pumps series MP-F are not suitable for liquids or particles.
These pumps only operate dry and particle-free gases.
