Wrong operation
Warning
Please make sure to install and operate the pump for the in-
tended use described in this instruction manual only.
Warning
The pump can only be operated within the parameters stated in
the technical data of chapter ‘8 Technical data’.
Warning
The pump is not designed for liquids or particles.
It is prohibited to operate the pump with condensate.
The pump head can be electrostatically charged by particles,
liquids and drops of condensate.
Condensate accumulated inside the pump head destroys the
pump.
If it is likely that humidity or condensation occurs, the pump
head needs to be rotated 180° facing downwards. With the
pump head facing downwards, the condensate can leave the
pump head.
Warning
The materials of the pump, which are in contact with the sample
gas, need to be suitable for the used sample gas.
Warning
In order to operate the pump, it needs to be securely installed.
Warning
Install the pump only in protected areas, sheltered from rain
and moisture.
Please make sure to provide sufficient ventilation.
Warning
Do not exeed the permitted maximum pressure within the pump
(gauge pressure).
Do not close the sample gas output. A sufficient sample gas
flow needs to be provided to prevent the pump pressure from
exceeding the permitted maximum pressure value.
A sufficient sample gas flow also prevents the temperature of
the pump head to increase over the permitted temperature
range.
Warning
If components downstream from the pump can block or reduce
the sample gas flow, appropriate measure, e.g. a pressure
valve, needs to be installed to prevent the process pressure
from exceeding the maximum permitted pressure value.

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.
To open the needle valve completely, turn out the valve until it stays at 35 mm (lowest pump capacity).
To close the needle valve completely, turn in the valve, until it stays at 25 mm (highest pump capacity)
After adjusting the needle valve, the locknut (see position ①) 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.

•To connect the suction and pressure line, please loosen the union nut of the compression ring
fitting counter clockwise. Be sure to remove the union nut carefully from the fitting. There is a
loose clamp ring inside the union nut.
•Slide the nut over the connecting tube.
•Slide the clamp ring with the thicker bulge facing the nut, over the connecting tube.
•Slide the connecting tube on the support nipple of the fitting.
•Hand-tighten the nut. The connecting tube is now slip-proof and pressure-tight mounted to the
tube connection fitting.
•Suction and pressure lines need to be installed in such a way that the pump is protected against
ingress of condensate or dust.
Note
Because of compression of sample gases, it is possible that condensate
builds up in the pressure line. This pressure must be reduced.
For example, reduce the pressure with a valve in the pressure line upstream
of the pump or with the integrated needle valve.
Start up
Before commissioning, be sure to comply with all applicable facility- and process-specific safety
measures.
Make sure to operate the pump for the intended use described in chapter 5 only.
Before commissioning, be sure to comply with all applicable safety regulations and measures of the
involved sample gases. The materials of the pump, which are in contact with the sample gas, need to
be suitable for the used sample gas. Before operating the pump, make sure that the materials of the
pump head, bellows and valves (for pump materials: see chapter ‘8 Technical data’) are suitable for the
used sample gas.
Follow these instructions before initial start-up:
•Ensure that the pump is securely tightened to the surface.
•Only sample gas which withstands the pressure and temperature within the pump and does not
built-up condensate is suitable for operation.
•Make sure that the pump does not start-up against pressure or vacuum.
•Before start-up and restarting, atmospheric pressure must be present in the suction and pressure
lines. Even when the power has been cut off for only a short period, the suction and pressure
lines need to have atmospheric pressure. After a pump standstill, the pressure in the sample gas
lines needs to be set back to atmospheric pressure.
•Never exceed the maximum permitted operating pressure pressure (for details see chapter ‘8
Technical data’).
•Only insert a sample gas flow controller or restriction device into the suction line. This protects
the pump bellows from damages, and prevents the pressure from exceeding the maximum per-
mitted operating value.
•Monitor the pressure, when a sample gas flow controller or restriction device is inserted in the
suction line. This prevents the pressure to exceed the maximum permitted operating pressure.
•Monitor the pressure if necessary.
