6 INTRODUCTION
The MP48-R diaphragm pump is suitable for 100% oil-free delivery of corrosive gases. Its perfor-
mance and design are specially adapted to the requirements of the analysis technology. The pump is
gas-tight and operates maintenance-free.
PROPER USE
The MP48-R is exclusively intended for transferring gases and vapors.
Install and operate the pumps only under the operating parameters and conditions described in chapter
9.
The pumps may only be operated when fully assembled.
Ensure that the installation site is dry and that the pump is protected from the sun, rain, spray, splash
water, pot water and other contaminants.
Regularly check the tightness of the connections between the piping of the application and the pump (or
the casing of the pump), leaking connections may release dangerous gases and vapors from the pump-
ing system.
Before pumping a medium, check whether the medium can be pumped without danger in the specific
application.
Before using a medium, check the compatibility of the materials of the pump head, diaphragm and valves
with the medium.

The elastic diaphragm (Figure 4/4) is moved up and down by the eccentric (Figure 4/5) and the connec-
tion rod (Figure 4/6). In the downward stroke it aspirates the gas to be transferred via the inlet valve
(Figure 4/2). In the upward stroke, the diaphragm presses the medium out of the pump head via the
outlet valve (Figure 4/1). The transfer chamber (Figure 4/3) is hermetically separated from the pump
drive (Figure 4/7) by the diaphragm.

16 MP48-R | 1.00.00 www.mc-techgroup.com
12 INSTALLATION INSTRUCTIONS
When installing the pump make certain that accident prevention regulations and safety instructions in-
cluding those for subsequent operation are observed. The safety instructions in chapter 3 must be ob-
served.
Note
Observe the relevant safety regulations for the pumped media.
To avoid disturbing heat accumulation, the pump should be installed away
from heat sources and freely ventilated.
When installed outdoors, the pump must be installed in a protective hous-
ing, frost-free in winter and sufficiently ventilated in summer. Direct sun-
light should be avoided.
T
Note
Pumps contain mechanical moving parts that can cause vibrations. In or-
der to avoid damage to the pump and peripheral components/equipment,
as well as to limit the acoustic noise development to a minimum, a suitable
vibration decoupling must be provided. M&C can supply anti-vibration pad
for this purpose.
This also applies explicitly to the connection of the sample gas lines to the
pump head.
MOUNTING THE PUMP
Only install and operate the pumps under the pneumatic operating parameters and conditions described
in chapter 9. Observe the safety instructions in chapter 3.
Note
Before installation, store the pump at the installation location to bring it
up to ambient temperature.
Refer to Figure 5 for mounting dimensions.
Warning
Danger of burns from hot surfaces
Hot surfaces may be caused by overheating of thepump.
Install the pump so that the motor fan can intake sufficient cooling
air.
Mount the pumps in such a way that their fan blade can draw in sufficient cooling air.
Mount the pumps at the highest point in the system and/or with the pump head facing downward to
prevent condensate from accumulating in the pump head - this will increase the operating time.
When installing, make sure that there are no combustible or thermally malleable objects placed in the
immediate ambient of the hot pump parts (head, motor).
Make sure that the installation location is dry, and the pump is protected against sun, rain, splash,
hose and drip water as well as other pollutions.

www.mc-techgroup.com MP48-R | 1.00.00 17
Make sure, that the installation location is accessible for maintenance and service.
The IP protection class of the pump motor is indicated on the type plate.
Warning
Condensate accumulated inside the pump head destroys the pump.
Condensate can form, for example, if the pressure dew point is ex-
ceeded or if there is a malfunction in the sampling process. If conden-
sate is to be expected, then the following measures must be taken:
Turn the pump head downwards so that the gas connections point
downwards.
Mount the pump at the highest point in the system. If this is not
possible, route the outlet tubing away from the pump at an incline.
These measures allow condensate formed in the pump outlet to flow
out of the pump head and be safely drained.
Protect the pump from dust.
Protect the pump from vibrations and jolts.
Warning
Personal injury and/or damage to property because of vibration
In conjunction with adjacent components, vibration of the pump may re-
sult in crushing and/or damage to these components.
Make sure that vibrations of the pump do not result in hazards as-
sociated with adjacent components.
Protect the pump against contact and intrusion of foreign matter.

If the pump is used to transfer moist gases, condensation may form in the pump head during operation.
Among other things, this reduces the pump capacity.

www.mc-techgroup.com MP48-R | 1.00.00 19
To ensure optimum suction performance, it is advisable to align the pump head downwards so that the
condensation can simply run out of the pump head. To do this, the compressor housing and pump head
(depending on the installation situation) can be rotated and assembled in 90° increments.
