6 INTRODUCTION
Due to the implementation of resistant materials the pump type MP06/12 can be used in a wide range
of applications with aggressive and corrosive gases.
7 DESCRIPTION
The pump head and all wetted parts of the diaphragm pumps type MP06/12 are made of PTFE respec-
tively FKM. This grants a high resistance against aggressive and corrosive components in the sample.
The pumps work 100 % lubricant free which means that the sample remains analytical unaffected.
The special diaphragm and valve system guarantees a high level of reliability and a minimum of mainte-
nance.
The pumps are available in 230 V 50 Hz.
The maximum flow capacity of the MP06 is 5.5 l/min. For higher flow up to maximum 11 l/min we rec-
ommend the pump type MP12.
The range of the sample temperature during operation is between –20 °C [-4 °F] and maximum +80 °C
[176 °F].
NOTE!
The diaphragm pumps series MP06/12 are not allowed for liquid medium. Max-
imum temperature for medium during operating: -20 °C [-4 °F] .... +80 °C
[176 °F]. Before use please check the compatibility of the material.

NOTE!
Attention must be paid to the requirements of IEC 364 (DIN VDE
0100) when setting high-power electrical units with nominal volt-
ages of up to 1000 V, together with the associated standards and
stipulations.
Check the details on the type plate to ensure that the equipment is
connected up to the correct mains voltage. A main switch and
matching fuse must be provided externally! (EN 60335-1)
A protective motor switch is not necessary because the pump is
equipped with a thermal switch.
For electrical details see technical data.
•In case the standard mains cable with plug should not be used, a wiring plan is in the cover of the
junction box.
•The pump must be installed so that contact with live parts (connections, possibly windings) is impos-
sible.
10.3 PNEUMATIC INSTALLATION
•Remove the protection plugs from the connection threads (thread size G1/8”i).
•Accessories like hose connections are screwed into the connection threads by sealing tape (using
M&C connectors sealing tape is not necessary).
•Connect the suction and pressure lines.
•Arrange the suction and pressure lines so that condensate cannot run into the pump.
NOTE!
The pump must only be used in the conditions specified in the technical data.
The pump should not be close to heat sources and freely ventilated to prevent
any accumulation of heat.
For outdoor installation, the pump must be installed in a housing protected
from frost in the winter and sufficiently ventilated in summer. Exposure to di-
rect sunlight must be avoided.
11 SUPPLY LINE CONNECTIONS
11.1 HOSE-/TUBE CONNECTIONS
The gas inlet and outlet hoses/tubes are connected on the top of the pump. Standard G 1/8" threaded
joints are available for the connection of the gas sample lines.
NOTE!
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!
When connecting the sample gas supply hoses or tubes to the corresponding threaded connections,
pay attention to the following items:

www.mc-techgroup.com MP06, MP12 | 1.00.02 13
NOTE!
The tightness of the connections can only be guaranteed if the end section of
the connection hose/tube is flat (use a hose-cutter) !
•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 loosely into 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 can not slip and is resistant to pressure.
The appropriate tube or hose threaded joint connections are available optionally from M&C.
12 STARTING
Specific safety instructions for media being handled must be observed.
Before pumping a medium, the compatibility of materials of pump head, diaphragm and valves with the
medium must be checked (for pump materials: see technical data).
The following steps should be carried out before initial start-up:
•The pump must not start against pressure or vacuum. When it is switched on, the pressure in the
suction and pressure lines must be atmospheric. This must be so even when the pump restarts after
the power has been cut off for a short period.
•The maximum permissible operating pressure (see technical date) must not be exceeded, even when
the flow is restricted.
•To prevent the maximum permissible operating pressure being exceeded, restriction or control of the
air or gas flow should only be carried out in the suction line.
•If restriction or control of the air or gas flow is made on the pressure side, ensure that the maximum
permissible operating pressure is not exceeded.
•When the pump is at a standstill, the inlet and exhaust must be at normal atmospheric pressure.
•Diaphragm and valve plates are the only parts subject to wear. Wear is usually indicated by a drastic
reduction in the pneumatic performance. When replacing parts, proceed as described in section 9.
•Ambient conditions: see technical data section 3.

13 CLOSING DOWN
If the pump is putting out of action for a short time, no particular measures need to be taken.
If the pump is out of action for a longer time, please purge it with Nitrogen.
NOTE!
The area in which the pump is situated when not in use must be kept
free of frost at all times!
WARNING!
Aggressive medium is possible.
Wear protective glasses and proper protective clothing during dis-
assembly, repair or cleaning!
14 MAINTENANCE
Before maintenance is carried out, it is necessary that the specific safety procedures pertaining to the
system and operational process are observed!
WARNING!
Dangerous voltage.
It is necessary to take the pump off the mains before any assembly,
maintenance or repair work is carried out!
Diaphragm and valve plates are the only parts of the pump subject to wear. They are simple to change.

15 TROUBLE SHOOTING
Before working on the pump, disconnect the pump from the power supply, ensure and check that it is
voltage free. The following troubleshooting instructions are hierarchical, i.e. practical to use in the order
given.
Problem/indication
Possible cause
Action/Check
Pump does not op-
erate
No main supply.
Check power supply. Check plug for correct fit.
Connections or lines are
blocked.
Remove blockade.
An external valve is closed
or a filter is blocked.
Open valve or clean blocked/dirty filter.
Liquid (condensate) has col-
lected in the pump head.
Let the pump for a few minutes pumping air.
Flow, pressure or
vacuum too low
Diaphragm or valves are
worn out.
Change worn out diaphragm or/and valves.
First compare the achieved
pump capacity with the tech-
nical data in chapter 1.2 or
the data sheet..
The pump is not designed for this condition.
There is pressure on the
pressure side and at the
same time vacuum or a
pressure above atmospheric
on the suction side.
The pump is not designed for this condition.
The cross-sections of pneu-
matic lines or connected
components are too small,
or they are restricted.
To measure the capacity values, disconnect the
pump from the system; even a tube with a too
small cross-section or, for example, a valve in-
stalled in the system can change the measured
value considerably.
Leaks at the connections,
the lines or at the pump
head. Diaphragms or valve
plates are defective or head
parts dirty.
Seal leaks,
tighten the screw connections,
replace defective parts,
clean or replace dirty parts.
NOTE!
If you are unable to find any of the defects listed although the pump is not
working properly, return the pump to M&C for inspection.
If you send your diaphragm pump to M&C Customer Service for repair,
please indicate the pumped medium.
In particular, our workshop must be informed about aggressive pumped me-
dia. If you have pumped dangerous or highly aggressive gases with the
pump, clean your pump before shipping.
