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 respectively 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 maintenance.
The pumps are available in 230V 50Hz.
The maximum flow capacity of the MP06 is 5,5 l/min. For higher flow up to maximum 11 l/min we

assembly, repair or cleaning!
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 dras-
tic 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.

WAR N ING !
It is necessary to take the pump off the mains before any assembly,
maintenance or repair work is carried out!
WAR N ING !
Aggressive medium is possible.
Wear protective glasses and proper protective clothing during
disassembly, repair or cleaning!
NOTE!
Always change valve plates, diaphragm and sealing rings at the
same time.
14 MAINTENANCE
Before maintenance is carried out, it is necessary that the specific safety procedures pertaining to the
system and operational process are observed!
