5 USED TERMS AND SIGNAL INDICATIONS
6 INTRODUCTION
The diaphragm pump MP47-Z-BPR150 is suitable for the 100 % oil-free delivery of corrosive gases
with changing pressure conditions. The capacity and construction of the pump is especially designed
Gas sampling and gas conditioning technology 6-1.1.7-ME
7
NOTE!
The diaphragm pumps of the series MP47 must not deliver liquids.
for the problems in the analyze technique. The pump is gas-tight and operates without any maintenance.
7 RANGE OF APPLICATION
All sample contacting parts of the diaphragm pump MP47-Z-BPR150 are made of PTFE, PVDF and
Viton or Kalrez. The lifted gas remains analytically pure due to the fact that the pump works absolutely
without any lubricant. A special diaphragm and valve system guaranties a long life time and no maintenance is necessary. The pump is available for 230V or 115V.
One problem in the analyze technique, when lifting gases via filters, is that the filters are clogged after
a longer period of time. This causes an increasing differential pressure above the filter and subsequently, a higher suction pressure for the pump is necessary. This, however, results in a decrease of
the adjusted pump capacity.
In order to avoid this negative influence, the M&C diaphragm pump MP47-Z-BPR150 is equipped with
a fully adequate bypass admission pressure regulator inside the pump head. Independent from the
changing entry pressure, the bypass admission pressure regulator keeps the pressure at the pump
outlet constant, so that the adjusted pump capacity resulting thereof remains constant as well.
For example, the entry pressure may vary from 0,46 bar abs. to 1,1 bar abs. for a pump capacity of
250Nl/h.
The outlet pressure is adjusted at works to 200mbar overpressure (adjustable up to 300mbar).
• Delivery of gases and vapors with a temperature of - 30 °C to + 80 °C.
• Maximum admissible operating overpressure, final vacuum, pump capacity: see technical data.
• Before using the pump in unknown mediums, check the compatibility of the pump head and valve
materials with the respective medium.
8 AMBIANCE
Please keep the following ambient conditions during operation:
Range of ambient temperature during operation: -10 °C to + 40 °C.
The pumps must be protected against water and dust effects.
During operation, a sufficient supply of cooling air must be provided.
8.1 SAFETY
The pumps MP47-Z-BPR150 are executed according to protection IP20 and do not provide any protection against touching and foreign bodies.

* Maximum operating pressure for a constant outlet pressure and as a result a constant flow rate of the mea-
suring gas.
** The minimum operating pressure that still guarantees a constant pump capacity is changing according to the
necessary gas volume flow adjusted behind the pump and to the outlet pressure adjusted on the pressure
regulator. The lower the necessary gas volume flow and the outlet pressure, the lower is the minimal possible operating pressure that still guarantees a constant outlet pressure and therefore a constant sample gas
volume flow.

It must also be taken care to protect the pump against penetration
of foreign bodies.
NOTE!
Pumps have mechanical moving parts that can induce vibrations.
To prevent damages at the pump or at peripheral components /
facilities as well as minimizing noise development an appropriate
vibration decoupling is necessary. For this M&C can deliver e.g.
anti-vibration pads.
This explicit is also valid for the connection of the sample lines at
the pump head.
• Check the goods for any damage incurred during transport and, if necessary, inform your trans-
port insurer of any damage.

NOTE!
The diaphragm pump is only to be used under the special conditions
specified in the technical data. Do not place the diaphragm pump near
to heat sources and provide sufficient aeration in order to avoid heat
accumulation.
When mounting the pump outside, it must be installed in a protecting
housing that is frost-protected in winter and sufficiently aerated in
summer. Direct solar radiation must be avoided.
NOTE!
Do not twist the valve body when mounting the hose connections because it can influence the sampling capacity of the pump. Do not interchange the hose connections for the sample gas inlet and outlet. The
connections are identified accordingly. After all lines being connected,
check whether the connection is tight.
The tightness of the connection can only be guaranteed if the border of
the connection hose is straight (use a hose cutter).
11.3 PNEUMATICAL CONNECTION
Remove the protection plug from the gas connection thread (thread size G1/4”).
Accessories such as tube connections are screwed into the connection thread by means of a
sealing tape (when using the screw fitting from M&C, no sealing tape is necessary).
Connect the suction and pressure line.
Mount the suction and pressure lines in a way to avoid condensate flowing into the pump.
12 SUPPLY CONNECTIONS
12.1 HOSE CONNECTIONS
The connection is made on top of the pump. There are standard connections with G1/4” inside
threads.
When connecting the hoses to the hose connection fittings to be supplied as option, please note the
following:
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 placed loose in 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

NOTE!
The location where the pump is installed must be free of frost also
when it is not in use.
WARN IN G!
Aggressive condensate possible.
Wear safety glasses and appropriate protection clothes when
dismounting, repairing or cleaning the pump!
13 START UP
Before starting up, please observe the safety measures related to the installation and the process!
Also respect the respective safety prescriptions and measures related to the sampled gases. Before
pumping the medium, please check the compatibility of the gas with the materials of pump head,
diaphragm and valves (for pump materials: see technical data).
The following steps have to be executed for the initial start up:
The pump must not start against pressure or vacuum.
When switching on the pump, the pressure in the lines must be atmospheric. The same is
valid when the pump is restarted after a power cut off for a short period.
The maximum permissible operating pressure (see technical data, chapter 9) must not be ex-
ceeded.
To prevent the maximum permissible operating pressure being exceeded, restriction or control
of the gas flow should only be carried out in the suction line.
If restriction or control of 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 lines must have got the 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 chapter 15.
