6INTRODUCTION
This diaphragm pump MP47 ... is suitable for corrosive gases. It is constructed especially for problems in the anal-
ysis technique.
7DESCRIPTION
The pump MP47 has a PTFE-head. All sample contacting parts are out of PTFE. The pump works absolutely lubri-
cant free, so gases remain analytically unchanged. Due to a special diaphragm and valve system, the pump oper-
ates maintenance-free.
The MP47 ... is available in 230 V or 115 V and can be equipped with an Ex motor for applications in hazardous
areas as well.
The standard MP47 ... is designed for normal applications at a maximum gas flow of 6 Nl/min. Up to flow rates of
17 Nl/min we recommend the type MP47-Z.
With the option MP .../R a needle valve is build into the pump-head to adjust the flow rate (see data sheet 10.2).
M&C provides for the series MP47 ... pump as option a diaphragm breakage monitoring. MP47 .../D is equipped
with a special double-membrane safety system (see data sheet 10.3).
•Maximum temperature for medium during operating: -30 to +80 °C [-22 to 176 °C].
•The pump must be protected from the effects of dust and water.
•Before use please check the compatibility of the material.

8AMBIENT CONDITIONS
When the pump is operating the following ambient conditions must be maintained:
• Ambient temperature during operating: -10 to + 40 °C [14 to 104 °F].
• The pump must be protected from the effects of dust and water.
• During operating an adequate supply of air for cooling must be provided.
8.1 SAFETY
The protection class of the pumps MP47/MP47-Z is IP20 and so offer no protection against contact or foreign
bodies.
Warning
It is therefore essential to provide protection for persons against contact
with live parts (e.g. electrical connections, motor windings) and moving
parts (e.g. fan). Protection against the entry of foreign bodies must also be
provided.
The pumps have no protection against water. In this case too, as far as is relevant, measures to protect the pump
must be taken before start-up.
Warning
Aggressive medium is possible.
Wear protective glasses and proper protective clothing during dis-as-
sembly, repair or cleaning!
The pumps may only be used for their intended purpose.
Note
Components connected to the pump must be designed according to the
pneumatic performance of the pump (see technical data).
Take care that safety regulations are observed when connecting the pump
to the power supply. Specific safety instructions concerning sample must
be observed.

14 INSTALLATION INSTRUCTIONS
When installing the pump make certain that accident prevention regulations and safety instructions including
those for subsequent operation are observed. The safety instructions in chapter 8.1 Safety must be observed.
Note
The pump must only be used in the conditions specified in the technical
data. The pump should be installed away from heat sources and freely ven-
tilated 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 direct sunlight must be
avoided.
The protection class of the pumps MP47, MP47-Z, MP47/R, MP47-Z/R, MP47D is IP20 and so offer no protection
against contact or foreign bodies.
Warning
It is therefore essential to provide protection for persons against contact
with live
parts (e.g. electrical connections, motor windings) and moving
parts (e.g. fan). Protection against the entry of foreign bodies must also be
provided.
Note
Pumps have mechanical moving parts that can induce vibrations. To pre-
vent 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.

14.1 MECHANICAL
•The dimensions of the mountings are given in figure 7 and figure 8.
•The pump is provided for assembly and therefore it has to be fastened with screws.
•Install the pump so that the fan can draw in sufficient cooling air.
•Install the pump so that accidental finger contact with the fan is impossible.
•Mounting the pump at the highest place in system and/or with pump head downside so that conden-
sate cannot be assembled inside the head - this increases the operating time.
Figure 7 Dimensions (mm) pump MP47..
14.2 ELECTRICAL
When making the electrical installation the safety regulations must be observed. In particular make sure that the
electricity supply is isolated before trying to connect the pump.
The diaphragm pumps type MP47, MP47/R, MP47-Z

14.3 PNEUMATIC
•Remove the protection plugs from the port threads (thread size G 1/4”).
•Accessories like hose connections are screwed into the port 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 be installed away from 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 direct sunlight must
be avoided.
15 SUPPLY LINE CONNECTIONS
15.1 HOSE-/TUBE CONNECTIONS
The gas inlet and outlet hoses/tubes are connected on the top of the pump. Standard G 1/4" threaded joints are
available for the connection of the gas sample lines.
Note
The valve body must be fixed while mounting the fittings
because moving may
change the pump capacity. Do not confuse hose-/tube connections for sample gas in-
let and outlet; the connections are labeled accordingly! Check for tightness of all sam-
ple lines after connection!
The tightness of the connections can only be guaranteed if the end section of the con-
nection hose/tube is flat (use a hose-cutter)!
When connecting the sample gas supply hoses or tubes to the corresponding threaded connections, pay attention
to the following points:
•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
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 nut.

www.mc-techgroup.com MP47 | 1.01.02 19
•Push the hose/tube onto the supporting nipple in the threaded joint.
•Tighten the sleeve nut by hand.
The tube is now mounted in a non-slip and pressure-resistant manner.
Connection fittings for DN 4/6 or DN 6/8 are optionally available from M&C.
16 START UP
Before commissioning, the plant- and process-specific safety measures must be observed!
The relevant safety regulations and measures must be observed for the media to be pumped. Before using a me-
dium, the compatibility of the materials of the pump head, diaphragm and valves with the medium must be
checked (for pump materials: see technical data). The following steps must be carried out during initial commis-
sioning:
•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
have 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 per-
missible operating pressure is not exceeded.
•When the pump is at a standstill the inlet and outlet must be at normal atmospheric pressure.
•Diaphragm and valve plates are the only parts subject to wear. Wear is usually indicated by a drastic re-
duction in the pneumatic performance. When replacing parts proceed as described in chapter 18.
•Ambient conditions: see technical data.
17 CLOSING DOWN
Note
The area in which the pump is situated when not in use must be kept free of
frost at all times!
No further special measures need to be taken when decommissioning.

20 MP47 | 1.01.02 www.mc-techgroup.com
Warning
Aggressive medium is possible.
Wear protective glasses and proper protective clothing during disassembly,
repair or cleaning!
18 MAINTENANCE
Before the maintenance work is carried out, it is necessary that the specific safety procedures pertaining to the
system and operational process are observed!
Warning
It is necessary to take the pump off the mains before any assembly, mainte-
nance 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.
Warning
Aggressive medium is possible.
Wear protective glasses and proper protective clothing during disassem-
bly, repair or cleaning!
