►Instructions to avoid the danger situation
WARNING
Potential pending danger
Indicates a pending danger that could result in death or serious injury if not observed.
►Instructions to avoid the danger situation
CAUTION
Potential pending danger
Indicates a pending danger that could result in minor injuries if not observed.
►Instructions to avoid the danger situation
NOTICE
Danger of damage to property
Is used to highlight actions that are not associated with personal injury.
►Instructions to avoid damage to property
Notes, tips or examples indicate important information about the product or about this docu-
ment.
2.2 Safety instructions
All safety instructions in this document are based on the results of the risk assessment carried out in
accordance with Machinery Directive 2006/42/EC Annex I and EN ISO 12100 Section 5. As far as appli-
cable, all unit life cycle phases have been considered.
Risks during transport
WARNING
Danger of serious injury due to falling objects
Due to falling objects there is a risk of injuries to limbs through to broken bones.
►Take particular care and pay special attention when transporting products manually.
►Do not stack the products.
►Wear protective equipment, e.g. safety shoes.
Safety
10/58

Risks during installation
DANGER
Danger to life from electric shock
Touching exposed and voltage-bearing elements causes an electric shock. Improper connection of
the mains supply leads to the risk of touchable live housing parts. There is a risk to life.
►Before the installation, check that the connection leads are voltage-free.
►Make sure that electrical installations are only carried out by qualified electricians.
►Provide adequate grounding for the device.
►After connection work, carry out an earthed conductor check.
CAUTION
Danger of injury from bursting as a result of high pressure in the exhaust line
Faulty or inadequate exhaust pipes lead to dangerous situations, e.g. increased exhaust pressure.
There is a danger of bursting. Injuries caused by flying fragments, the escaping of high pressure, and
damage to the unit cannot be excluded.
►Route the exhaust line without shut-off units.
►Observe the permissible pressures and pressure differentials for the product.
►Check the function of the exhaust line on a regular basis.
CAUTION
Danger of burns on hot surfaces
Depending on the operating and ambient conditions, the surface temperature of the vacuum pump
can increase to above 70 °C. If access to the vacuum pump is unrestricted, there is a danger of burns
due to contact with hot surfaces.
►Install suitable touch protection if the vacuum pump is unrestrictedly accessible.
►Allow the vacuum pump to cool down before carrying out any work.
►Contact Pfeiffer Vacuum for suitable touch protection in system solutions.
CAUTION
Health hazard from increased noise emission
Operation without silencer leads to higher noise emissions. Remaining in the close proximity of the
vacuum pump for a sustained period of time may cause hearing damage.
►Install a suitable exhaust line.
►Wear hearing protection.
Risks during operation
WARNING
Health hazard through poisoning from toxic contaminated components or devices
Toxic process media result in contamination of devices or parts of them. During maintenance work,
there is a risk to health from contact with these poisonous substances. Illegal disposal of toxic sub-
stances causes environmental damage.
►Take suitable safety precautions and prevent health hazards or environmental pollution by toxic
process media.
►Decontaminate affected parts before carrying out maintenance work.
►Wear protective equipment.
Safety
11/58

WARNING
Danger of poisoning due to toxic process media escaping from the exhaust pipe
During operation with no exhaust line, the vacuum pump allows exhaust gases and vapors to escape
freely into the air. There is a risk of injury and fatality due to poisoning in processes with toxic process
media.
►Observe the pertinent regulations for handling toxic process media.
►Safely purge toxic process media via an exhaust line.
►Use appropriate filter equipment to separate toxic process media.
WARNING
Explosion hazard from reactive, potentially explosive or other hazardous gas/air mixtures
Uncontrolled inlet of gas at the gas ballast valve leads to sparks generated mechanically following
diaphragm rupture, hot surfaces or to potentially explosive gas/air mixtures in the vacuum system
caused by static electricity.
►If necessary, use inert gas for supplying the flushing gas in order to avoid a potential ignition.
WARNING
Risk of poisoning due to toxic process gases escaping
For intake pressures > 500 hPa, process gas may escape from the open gas ballast valve. There is a
risk of injury and fatality due to poisoning in processes with toxic process media.
►If necessary, use inert gas to avoid potential contamination.
►If necessary, use an extraction line.
CAUTION
Danger of burns on hot surfaces
Depending on the operating and ambient conditions, the surface temperature of the vacuum pump
can increase to above 70 °C. If access to the vacuum pump is unrestricted, there is a danger of burns
due to contact with hot surfaces.
►Install suitable touch protection if the vacuum pump is unrestrictedly accessible.
►Allow the vacuum pump to cool down before carrying out any work.
►Contact Pfeiffer Vacuum for suitable touch protection in system solutions.
CAUTION
Danger of injury from moving parts
After a power failure or a standstill as a result of overheating, the motor restarts automatically. There
is a risk of injury to fingers and hands if they enter the operating range of rotating parts.
►Safely disconnect motor from the mains.
►Secure the motor against reactivation.
►Dismantle the vacuum pump for inspection, away from the system if necessary.
CAUTION
Danger of burns on hot surfaces
In the event of a fault, the surface temperature of the vacuum pump can increase to above 105 °C.
►Allow the vacuum pump to cool down before carrying out any work.
►Wear personal protective equipment if necessary.
Safety
12/58

Risks during maintenance, decommissioning and in the event of malfunctions
WARNING
Danger to life from electric shock during maintenance and service work
The vacuum pump is only completely de-energized when the mains plug has been disconnected.
There is a danger to life from electric shock when making contact with live components.
►Before performing all work, switch off the mains switch.
►Disconnect mains cable from mains plug.
►Wait 2 minutes until the capacitors have discharged.
►Secure the vacuum pump against unintentional re-start.
WARNING
Health hazard through poisoning from toxic contaminated components or devices
Toxic process media result in contamination of devices or parts of them. During maintenance work,
there is a risk to health from contact with these poisonous substances. Illegal disposal of toxic sub-
stances causes environmental damage.
►Take suitable safety precautions and prevent health hazards or environmental pollution by toxic
process media.
►Decontaminate affected parts before carrying out maintenance work.
►Wear protective equipment.
CAUTION
Danger of burns on hot surfaces
In the event of a fault, the surface temperature of the vacuum pump can increase to above 105 °C.
►Allow the vacuum pump to cool down before carrying out any work.
►Wear personal protective equipment if necessary.
Risks during disposal
WARNING
Health hazard through poisoning from toxic contaminated components or devices
Toxic process media result in contamination of devices or parts of them. During maintenance work,
there is a risk to health from contact with these poisonous substances. Illegal disposal of toxic sub-
stances causes environmental damage.

3 Product description
3.1 Function
Diaphragm pumps are dry compressing displacement pumps. The movement of diaphragms generates
a periodic change of the suction chamber volume. The gas flow causes the valves to open and close
automatically. The pump unit is directly connected to the drive motor.

3.1.1 Drive
The drive motor is an alternating current motor with
●reversible voltage range on the voltage selector switch,
●thermal protection switch,
●mains switch and
●rubber connector
In event of excess temperature (> 95 °C), the thermic protection switch interrupts the motor current, but
does not offer a permanent shut-down of the motor. Once the motor has cooled down, the vacuum
pump restarts automatically.
3.1.2 Pumping system
Diaphragm pump MVP 040-2 has 2 pumping stages.
Diaphragm pump MVP 070-3 (C) has 4 pumping stages.
3.1.3 Cooling
The diaphragm pump is convection-cooled. The drive motor has its own fan.
3.1.4 Gas ballast
An integrated gas ballast system serves the controlled supply of ambient air or inert gas into the suction
chamber. Gas ballast supports the reduction of condensate accumulating in the pumping system.
