Basic Safety Instructions
2 Basic Safety Instructions
2.1 General Information
Warning notices must be observed. Disregarding them may lead to damage to health and
property.
The diaphragm pumps must be operated by personnel who can detect impending dangers
and take action to prevent them from materialising.
The manufacturer or authorized authorised workshops will only service or maintain the dia-
phragm pump if it is accompanied by a fully completed damage report. Precise information
about the contamination (also negative information if necessary) and thorough cleaning of
the diaphragm pump are legally binding parts of the contract.
Contaminated diaphragm pumps and their individual parts must be disposed of in accor-
dance with the legal regulations.
The local regulations apply in foreign countries.
2.2 Electricity
The diaphragm pumps of operation mode S1 are supplied. When the location of operation
mode S1 devices is changed, please note that the testing must be repeated in accordance
with DIN EN 0105, DIN EN 0702 and BGV A2.
The local regulations apply in foreign countries.
Please note the following when connecting the plug to the electrical power supply system:
• The electrical power supply system must have a protective connector according to DIN
VDE 0100-410 (IEC 60364-4-41).
• The protective connector must not have any breaks.
• The connecting cable must not be damaged.
2.3 Mechanical Systems
Improper use can lead to injuries or material damage. Observe the following instructions:
• Only operate the diaphragm pumps with hoses of the specified dimensions.
• The maximum permissible pressure of 1 bar at the suction connection must not be ex-
ceeded.
• Solid particles in the pumping medium impair the pumping action and can lead to dam-
age. Prevent solid particles penetrating into the pump.
• Hazardous substances must be separated out as far as this is technically possible before
they reach the pump.
• External mechanical stresses and vibrations must not be transmitted to the pump. Only
use flexible NW 8 laboratory hoses for connecting diaphragm pumps.
• The overpressure generated at the pressure port must not exceed 1 bar.
• The pump must not be used to suck up fluids. Lay the exhaust pipe so that it slopes
downwards, so allowing condensate to flow out of the pump. Collect the condensate and
dispose of it in an environmentally compatible manner.
• Prevent dyes exuding.
• Maintain a space of least 20 cm between the pump and adjacent parts in order to enable
the pump to cool.

Basic Safety Instructions
2.4 Hazardous Substances
The operating company bears the responsibility for the use of the diaphragm pump.
Hazardous substances in the gases to be pumped can cause personal injuries and property
damage. Pay attention to the warning notices for handling hazardous substances.
The local regulations apply in foreign countries.
Combustible Gases
Examine before switching on whether that can form gas combustible gas/air mixtures which
can be promoted! Consider the regulations of the guideline 1999/ 92 EEC.
Aggressive gases
The MPC series is designed for extracting aggressive gases.
The use of diaphragm pumps of the series MP of ILMVAC GmbH cannot be recommended
for such cases of application!
Poisonous gases
Use a separator when pumping poisonous or harmful gases. Prevent such substances from
leaking out of the appliance or pump. Treat these substances according to the applicable
environmental protection regulations.
Test the strength and leak-tightness of the connecting lines and the connected apparatus.
Prevent environmental poisons, e.g. mercury, getting into the diaphragm pumps. Fulfil the
requirements, for example:
• German Hazardous Substances Regulation (GefStoffV) of 15 November 1999
• Regulations 67/548 EEC and 88/379 EEC (classification, packaging, and identification of
substances),
• 11th GSGV explosion protection regulation (regulation of 12 December 1996 covering
putting devices and protective systems on to the market which are intended for areas at
risk of explosion)
• Manufacturer's safety data sheets on hazardous substances.
2.5 High Temperatures
The diaphragm pump may heat up as a result of the temperature of the gas being pumped
and through compression heat. Thermal tests at the limiting temperatures listed below
measured surface temperatures of 115 °C at the pressure port. Prevent the following maxi-
mum permissible temperatures from being exceeded.
• + 40 °C for the environment, and
• + 60 °C for the gas to be pumped.
The motor for single phase alternating current is protected against overload by an integrated
motor protection switch

Description
3 Description
3.1 Design
The diaphragm pump consists of a pump housing
and a drive motor.
The pump casing contains the drive unit and two
four pump heads. Each pump head contains a dia-
phragm and the work valves. Two pairs of pump
heads are arranged opposite each other. 1 to 4
stage pumps are supplied, depending upon the cir-
cuitry of the pump heads.
The pump heads are driven via an eccentric shaft
with a connecting rod.
Fig. 1 Diaphragm pump MPC 901 Zp
3.2 Areas of Application
ILMVAC Diaphragm Pumps are intended for:
• Pumping and compressing neutral and aggressive gases and vapours.
• Generating a vacuum down to an ultimate pressure < 1 mbar.
• Use in physical and chemical laboratories in trade and industry.
• Use for vacuum filtration, vacuum distillation and vacuum drying, and other vacuum tech-
nology applications.
3.3 Principle of Operation
Motor, eccentric shaft and connecting rod set the diaphragms in stroke movement. This
changes the size of the space between the diaphragms and pump head (pump chamber).
Increasing the size of the pump chamber opens the inlet valve while the outlet valve is
closed (intake process).
Decreasing the size of the pump chamber ejects the gas through the outlet valve.
The valves are actuated by the gas being pumped. A large proportion of fluid in the dia-
phragm pump minimizes the pumping efficiency.

Description
3.5 Gas ballast
When condensable vapours are pumped, they may be compressed above the saturated va-
pour pressure and condense.
Opening the gas ballast valve (1) in the
suction line of the last pump stage allows
air to flow into the pump chamber. This
prevents condensation and flushes the
pump clear.
Operation leads to:
- Increasing the ultimate pressure and
- Increasing the operating temperature.

The gas ballast valve is only provided as standard for MPC type diaphragm pumps. The fit-
ting into other pump types is an option or must be specified in the supply contract.
