►Do not stack the products.
►Wear protective equipment, e.g. safety shoes.
Safety
11/62

Risks during installation
DANGER
Danger to life from electric shock
Power supply packs that are not specified or are not approved will lead to severe injury to death.
►Make sure that the power supply pack meets the requirements for double isolation between
mains input voltage and output voltage, in accordance with IEC 61010-1 IEC 60950-1 and
IEC 62368-1.
►Make sure that the power supply pack meets the requirements in accordance with IEC 61010-1
IEC 60950-1 and IEC 62368-1.
►Where possible, use original power supply packs or only power supply packs that correspond
with the applicable safety regulations.
DANGER
Danger to life from electric shock
When establishing the voltages that exceed the specified safety extra-low voltage (according to IEC
60449 and VDE 0100), the insulating measures will be destroyed. There is a danger to life from elec-
tric shock at the communication interfaces.
►Connect only suitable devices to the bus system.
WARNING
Risk of injury due to incorrect installation
Dangerous situations may arise from unsafe or incorrect installation.
►Do not carry out your own conversions or modifications on the unit.
►Ensure the integration into an Emergency Off safety circuit.
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 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.
Risks during operation
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.
Safety
12/62

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.
►Provide suitable touch protection.
Risks during maintenance, decommissioning and in the event of malfunctions
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 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.

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.

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 Actuator
The diaphragm pump forms a compact unit with the electronic drive unit. The integrated electronic drive
unit permits the control and monitoring of pumping functions via the “remote” interface using a Pfeiff-
er Vacuum control unit.
3.1.2 Pumping system
The diaphragm pump has 2 diaphragm heads and 2 pumping stages.
3.1.3 Cooling
The diaphragm pump is convection-cooled and does not have 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.
3.1.5 Pressure sensor
The retrofittable RPT 010 digital pressure sensor with piezo/Pirani sensor measures the intake pressure
and extends the functionality of the vacuum pump.

pressure losses.
Condensate separator
Pfeiffer Vacuum recommends the installation of a condensate separator in case vapors are
formed from moisture during evacuation.
Procedure
1. Remove the blind plug from the vacuum connection.
2. Establish the shortest possible connection between vacuum pump and vacuum chamber.
3. Choose a minimum vacuum line diameter equal to the nominal diameter of the vacuum connec-
tion.
4. Depending on the pump type, use PVC or metallic hoses with flange connections from the Pfeiff-
er Vacuum component shop.
5. Connect the vacuum pump to the vacuum system using the vacuum connection.
5.3 Connect exhaust side
WARNING
Danger to life from poisoning where toxic process gases leak with no exhaust line
During normal operation, the vacuum pump expels exhaust gases and vapors freely into the air. In
processes involving toxic media, there is a risk of injury and danger to life due to poisoning.
►Observe the relevant regulations for handling toxic substances.
►Safely purge toxic process gases via an exhaust line.
