According to the ordering configuration:
●1 mains supply cable
4.1.2 Differences between pump versions
The multi-stage Roots pump technology in the ACP series meets the requirements of applications
where a clean and dry vacuum is needed.
SD standard version
The pump is designed for clean (dust-free) and non-corrosive gas pumping applications. Standard
pumps are equipped with a gas ballast device to improve pumping of light gases and avoid vapor con-
densation inside the pump.
G version
The pump is compatible with traces of corrosive gases. A purge gas stream protects low- and high-
pressure ball bearings and dilutes trace amounts of corrosive gases.
CV version
The pump is specially designed to prevent vapor condensation inside the pumping module with:
●A high gas ballast flow to warm up the pump and dilute condensable gases.
●An external drainable silencer to remove liquid from the pump exhaust.
●A gas purge to protect lip seals and ball bearings from condensable vapors.
CV versions extend the pure water vapor pumping capacity.
CP version
The pump design is based on a standard pump. It is specially made to recirculate gas or to recover
chemically inert gas. This refers to helium isotopes or rare gases, which are costly. The pump has a
pumping device on the housing but does not have a gas ballast or purge to prevent incorrect use.
LG version
The pump design is based on a standard pump. It is designed for pumping light gases (for example: He,
H) for ultimate pressures < 10 hPa. It has an ON/OFF manual gas ballast and a permanent air injection
line with a reduced flow. It can be used for fore pumping a turbomolecular pump used in high-vacuum
processes.
SH version
The pump design is based on a standard pump. It is used in applications where the backstreaming of
fluorine is critical, in particular those installations that use NEG (Non-Evaporable Getter pump) ion
pumps. The lubricants and seals used do not contain fluorine compounds.
Please contact Pfeiffer Vacuum for more detailed information on specific applications.

Ventilation
To guarantee the characteristics and performances of the pump within the boundaries of the operating
conditions:
●Do not obstruct the air vents.
●Keep the pump away from fixed walls, at a minimum using the value indicated on the diagram be-
low.
5.2 Connecting to the pumping line
The user and/or product integrator is ultimately responsible for the equipment and must apply the spe-
cific safety instructions, in accordance with local regulations.
WARNING
Risk of crushing or cutting in case of contact with moving parts
The pump inlet flange is large enough for body parts (fingers or hands) to the inserted into it, present-
ing a risk of crushing due to contact with moving parts. The inlet and exhaust ports should be sealed
with blanking plates before connection.
►Wait for the pumping line to be connected before removing the blanking plates.
►Wait for the pump to be connected before powering on.
General instructions for installing the pump in the pumping line in accordance with industry
best practices
The inlet and exhaust connections must not put undue strain on the pumping line that could cause leak-
age.
1. Only use accessories on the inlet and exhaust lines with materials and sealing properties that are
compatible with the gases being pumped. Refer to the connection accessories catalog available at
the Pfeiffer-Vacuum website.
2. When assembling the pumping line, include accessories for isolating the pump from the pumping
line and making maintenance easier to carry out (pump inlet and exhaust isolation valves, purge
valves, etc.).
3. The O-rings located under the blanking plates are not compatible with all applications. Product
users or integrators are responsible for installing O-rings that are compatible with their ap-
plications.
Installation
19/56

4. Remove the blanking plates used to seal the inlet and exhaust ports.
5. Keep the blanking plates, screws and washers for reuse when transporting the pump.
6. Ensure that no screws, washers or other objects are dropped into the pump inlet.
7. Fit flexible tubes in the pumping line to reduce the transmission of vibration.
8. Perform a leak test on the entire pumping line after installation.
5.2.1 Connection on the pump inlet side
Make sure that the parts or chambers connected to the inlet of our products can
withstand a negative pressure of 1·10-3 hPa relative to atmospheric pressure.
To achieve the optimum pumping speed, make the pumping line as short and straight as possible
and ensure that its inside diameter is not narrower than the pump inlet flange inside diameter.
The product is not designed to withstand loads on its inlet flange which may compromise stability.
●Mechanically attach the vacuum chamber separately from the pump.
●Use only dry parts and clean, grease-free, dust-free pipelines.
●It may be necessary to install an inlet filter (particle filter or condensable filter).
●If necessary, install an isolation valve on the inlet which closes when the pump stops.
5.2.2 Connection on the pump exhaust side
DANGER
Risk of poisoning in case of contact with toxic substances and by-products generated by the
process
The vacuum pump, pumping line components and operating fluids may potentially be contaminat-
ed with toxic, corrosive, reactive and/or radioactive substances related to the process and harmful to
health.
►Always connect the pump exhaust to an exhaust extraction system.
Ensure that all components in the exhaust line have a maximum pressure rating
that exceeds the highest pressure the pump can generate.
Pump exhaust is equipped with an anti-noise device.
