1. Safety Precautions
Obey all relevant safety requirements (regulations and guide-
lines) and adopt suitable safety measures.
☞Read and follow all the instructions in this manual.
☞Inform yourself regarding:
- Hazards which can be caused by the pump;
- Hazards which can arise in your system;
- Hazards which can be caused by the medium being
pumped.
Use the equipment for the intended use only (for generation
of vacuum).
☞Avoid exposing any part of the body to vacuum.
☞Obey notes on correct vacuum and electrical connections,
see section ”Use and operation”.
☞Make sure that the individual components are only
connected, combined and operated according to their
design and as indicated in the instructions for use.
☞Observe all safety and accident prevention regulations.
☞Check regularly that all safety requirements are being
complied with.
☞Do not carry out any unauthorised conversions or
modifications on the pump.
☞Check that mains voltage and current conform with the
equipment (see rating plate).
☞Adopt suitable measures to prevent any danger arising
from the formation of hot surfaces or electric sparks.
☞When returning the pump to us please note the shipping
instructions in Section 7.
Page Page
Modifications reserved
Adopt suitable measures to prevent dangers arising from
dangerous or explosive gases and ensure that the materials
of the wetted parts are compatible, see section “Technical
data”.
☞Adopt suitable measures to prevent the release of
dangerous, explosive, corrosive or polluting fluids.
☞Take adequate precautions to protect people from the
effects of dangerous substances, wear appropriate safety-
clothing.
☞Obey applicable regulations when disposing of chemicals.
Take into consideration that chemicals may be polluted.
Adopt suitable measures to prevent dangers arising from the
formation of explosive fluids or explosive or flammable mixtu-
res.
☞Use inert gas for gas ballast if necessary.
☞The user must take suitable precautions to prevent any
formation of explosive mixtures in the expansion chamber.
In case of a diaphragm crack, mechanically generated
sparks, hot surfaces or static electricity may ignite these
mixtures.

1.1. For Your Orientation
Instructions in the text
➡Operating instructions: Here you have to do something!
Symbols used
The following symbols are used throughout in the
illustrations:
Vacuum flange
Exhaust flange
Gas ballast valve
Power supply connection
Position numbers
Identical components and accessories parts have the same
position numbers in all illustrations.
V
Danger of damage to the pump or system.
Danger of personal injury.
Pictogram Definitions
Danger of burns from touching hot parts.
Due to the residual leak rate of the equipment, there may be
an exchange of gas, albeit extremely slight, between the envi-
ronment and the vacuum system.
☞Adopt suitable measures to prevent contamination of the
pumped substances or the environment.
Electronic equipment is never 100% fail-safe. This may lead to
an indefinite status of the equipment. Provide protective mea-
sures against misfunction and failure.
☞Stand still of the pump or operating a valve must not lead
to a critical dangerous situation under any circumstances.
Ensure that in case of failure the pump and the vacuum
system always will turn into a safe status.
☞In case of diaphragm cracks or leaks in the manifold pum-
ped substances mighty be re-leased into the environment
or into the pump housing.
☞Obey especially notes on operation and use and
maintenance.
Use only genuine spare parts and accessories.
☞Otherwise safety and performance of the equipment as
well as the electromagnetic compatibility of the equipment
might be reduced.
Ensure that maintenance is done only by suitable trained and
supervised technicians.
Ensure that the maintenance technician is familiar with the
safety procedures which relate to the product processed by
the vacuum system and that the equipment, if necessary, is
appropriately decontaminated before starting maintenance.
Obey local and national safety regulations.
Before starting maintenance vent the system, isolate the
pump and other components from the vacuum system and the
electrical supply and allow sufficient cooling of the pump.
In order to comply with law (occupational, health and safety
regulations, safety at work law and regulations for
environmental protection) vacuum pumps, components and
measuring instruments returned to the manufacturer can be
repaired only when certain procedures (see section “Notes
on return to the factory“) are followed. Danger of an electric shock.

Proper use
– The Diaphragm Pump MVP 020 may only be used for the
purpose of generating vacuum.
– Do not pump corrosive or explosive gases.
– Do not pump liquids.
– Do not operate the pump in locations where there is an
explosion hazard.
– Accessories other than those named in this manual may
not be used without the agreement of PFEIFFER.
– Do not use the connecting line between the two
membrane heads as a handle.
– The Diaphragm Pump MVP 020 may not be used for the
purpose of generating pressure.

3. Installation
3.1. Setting Up The Pump And Location
Obey national safety regulations and safety requirements
concerning the use of vacuum and electrical equipment.
➡Remove all packing material, remove the product from its
packing-box, remove the protective covers from the inlet
and outlet ports and keep, inspect the equipment.
➡If the equipment is damaged, notify the supplier and the
carrier in writing within three days; state the item number
of the product together with the order number and the sup-
plier’s invoice number. Retain all packing material for
inspection.
➡Do not use the equipment if it is damaged.
➡If the equipment is not used immediately, replace the
protective covers. Store the equipment in suitable conditi-
ons.
➡Read and obey this manual before installing or operating
the equipment.
➡Transport the pump at the provided handles.
➡If the equipment is brought from cold environment into a
room for operation, allow the equipment to warm up (pay
attention to water condensation on cold surfaces).
➡Make sure ventilation is adequate if pump is installed in a
housing or if ambient temperature is elevated.
➡Provide a firm level platform for the equipment and check
that the system to evacuated is mechanically stable and
that all fittings are secure.
Attention: Flexible elements tend to shrink when
evacuated.
To the best of our knowledge the equipment is in compliance
with the requirements of the applicable EC-directives and
harmonized standards (see “Declaration of conformity”) with
regard to design, type and model, especially directive
IEC 1010. This directive gives in detail conditions, under which
the equipment can be operated safely (see also IP degree of
protection).
➡Adopt suitable measures in case of differences, e. g. using
the equipment outdoors, installation in altitudes of more
than 1000 m above mean sea level, conductive pollution or
dewiness.
➡Anchor the pump if it is to be erected in a stationary positi-
on.
➡Anchoring is not necessary if the pump is not erected in a
stationary position.
➡Ambient temperature range + 12 ... +40 °C.
➡Where rack installation is involved, ensure adequate venti-
lation.
3.2. Connecting The Vacuum Side
➡Remove locking cap on intake connection.
➡Make connection between the vacuum system and pump
as short as possible.
➡Connect pump with intake connection to the apparatus.
➡Obey maximum permitted pressures and pressure differen-
ces, see section ”Technical data”. Do not operate the
pump with overpressure at the inlet.
➡If liquid - which would generate vapours - is present in the
system to be evacuated, a condensate trap must be fitted
upstream of the pump.
3.3. Connecting The Exhaust Side
Pressure can rise to dangerous levels in exhaust
lines. Therefore, lay exhaust side lines without
shut-off units. Do not connect the exhaust side
with a closed system on account of the danger
of bursting.
In certain applications, exhaust gases and vapours can be
very hot and represent a health and/or environment hazard.
➡Lay lines from the pump sloping downwards so that
condensate cannot run back into the pump, otherwise fit a
separator.
➡Due to the high compression ratio of the pumps, pressure
at the outlet port might be generated being higher than the
max. permitted pressure compatible with the mechanical
stability of the system.
➡Do not permit any uncontrolled pressurizing (e. g. make
sure that the exhaust pipeline cannot become blocked). If
you have an exhaust-isolation valve, make sure that you
cannot operate the equipment with the valve closed. Risk
of bursting!
➡Ensure that the system design does not allow the exhaust
pipeline to become blocked.
➡Avoid overpressure of more than 0.2 bar in case inert gas
is connected.
➡The diameter of the inlet and outlet pipeline should be at
the least as large as the diameter of the pump connection
pipelines.
