2.2. Design

The single stage UNO 005 A/2.5 A and two stage
DUO 2.5 A/AC Rotary Vane Vacuum Pumps are oil-immersed.
The pump stages and motor are mounted on a support stand.
Bearings and pumping chamber are supplied continuously
with pump fluid which both seals and lubricates. Pump fluid,
together with dirt and other particles, is expelled via the
pump valve and returned to the pump fluid reservoir. Foreign
matter and dirt particles are deposited on the floor of the
casing so that only clean pump fluid flows into the pump
circulation system. Intake ports, exhaust ports and gas
ballast valve are located on the support stand. The direct
drive, broad range voltage motor drives the pump via a
coupling. A built-in, thermal protection switch protects the
motor and the pump against overloading.
A hydraulically controlled high vacuum safety valve is
located between the vacuum connection and the pumping
system. The valve closes off the vacuum equipment without
delay when the pump is at a standstill and vents the pump.
The Rotary Vane Vacuum Pumps are in two versions
available:

Standard versions: UNO 005 A,

UNO/DUO 2.5 A

Version for Corrosive Gas Processes: DUO 2.5 AC

With regard to the Rotary Vane Pump DUO 2.5 AC please note
the following divergences compared with the standard versi­on:

- Corrosive gas type pumps are equipped with special
materials.

- Corrosive gas type pumps are equipped with a special gas
ballast valve (see section 4.5)

- Corrosive gas type pumps are operated with the synthetic
pump fluid F5 as standard.

The Rotary Vane Vacuum Pumps are suitable for the generati­on of rough and medium vacuum in the laboratory and for all
operations where small volume flow rates suffice. They can
also be used as backing pumps for small diffusion or turbo
molecular pumps.

Proper Use

– Rotary Vane Vacuum Pumps may only be used to generate

vacuum.

– Do not pump corrosive or explosive gases (a special versi-

on for these operations is available on request).

– Do not operate the pumps where explosive processes are

involved. This is only permitted with the "explosive" version
of the pump.

– Using accessories not named in this manual is not permit-

ted without authorisation from PFEIFFER.
Improper use will cause any rights regarding liability and
guarantees to be forfeited.

3.1. Preparations For Installation

Fill up with operating fluid before operating the
first time (included in a separate pack in the
delivery consignment).
When transporting, use only the handle

provided for the purpose. When filled with
operating fluid, do not tilt the pump otherwise operating fluid
could escape via the vacuum and exhaust flanges.

3.2. Pump Set-Up And Location

➡ Where stationary installation is involved, anchor the pump

on site.

➡ Sight glass 5 on the front side must be visible and the gas

ballast valve readily accessible.

➡ When installing the pump in a closed housing, ensure

there is sufficient air circulation.

Maximum angle of inclination to each side 10°
Maximum erection height 2000 m N.N
Maximum and minimum ambient temperature 40 °C
and 12 °C respectively
Maximum relative humidity 85%

3. Installation

3.3. Connections, Vacuum Side

➡ Keep the connection between the vacuum chamber and

pump as short as possible.

➡ Remove all scaling and loose particles from welded lines

prior to assembly.

– To protect the pump, separators, filters and cooling traps

etc. (see Section 9. Accessories) can be fitted upstream of
the pump. However, this does mean that owing to the
conductance value of the accessory, there is a reduction
in volume flow rate.

– For the intake lines, metal or PVC hoses with small flanges

are available for laboratory work.

3.4. Connecting The Exhaust Side

Pressure can rise to dangerous levels in exhaust
lines. Therefore exhaust lines should not be
fitted with shut-off units.
If, for internal works reasons, shut-off devices

are fitted, or if there is a risk of a build up of
excess pressure in the lines, observe all official accident
prevention safety regulations.

- Lay minimum diameter exhaust lines of DN 10.

- If the exhaust gases are being extracted, the pressure of

the exhaust must not fall below 200 mbar.

- Lay lines from the pump sloping downward so that no

condensate can flow back into the pump. Otherwise fit a
separator.

- Forces from the piping system may not be allowed to act

on rotary vane pumps which are anchored.
All piping to the pump must be suspended or supported.

Exhaust gases and vapours can be detrimental
to health and/or can pollute the environment.
For this reason, when working with toxic
substances it is essential to ensure compliance

with the applicable regulations. Only officially
approved filter systems may be used to separate out these
substances. This is also applicable to operations involving
poisonous, chemically unstable, polymerising or peroxide
forming gases (see Section 9 Accessories).

3.5. Connecting To The Mains Power Supply

Power connections must comply with local
regulations. Voltage and frequency information
given on the rating plate must correspond to the
mains voltage and frequency values.

– Voltage and frequency information given on the rating

plate must correspond to the mains voltage and frequency
values.

– The single phase drive motors of the UNO 005 A/2.5 A and

the DUO 2.5 A/AC are fitted with a built-in thermal
protection switch. A cable with connecting plug is fitted to

the motor for mains connection purposes.
– Motors can be supplied with or without ON/OFF switch.
– As standard drive motors two single phase motors for the

following tensions are suitlable:

230 V ± 15 % 50 Hz, and

208 V ± 10 % 60Hz or

100 V ± 10 % 50 Hz, and

110 V ± 15 % 60 Hz.

4. Operations

4.1. Filling Up And Checking The Operating
Fluid

Standard version pumps are tested with opera­ting fluid P3. Guarantees relating to attainment
of final pressures and trouble free functioning
apply only providing this operating fluid is used.

The delivery consignment contains sufficient operating fluid
for one filling.
Pumps for special applications (e.g. for pumping corrosive
gases) can be operated with special operating fluids such as
F5, C100 and other Pfeiffer operating fluids. The use of such
operating fluids requires prior authorisation from the
manufacturer.
P3 must be disposed of in accordance with local waste dispo­sal regulations.

➡ Remove operating fluid filler screw 3.
➡ Fill up with operating fluid so that the level is between the

two markings on the sight glass or on the casing (for
pumps with replaceable sight glass ; also refer to rating
plate for correct quantity.
– The minimum level is the lower marking on sight glass 5.

➡ Replace operating fluid filler screw 3; be careful with

O-ring 48.

➡ Check operating fluid level only when the pump is warm

and running and vacuum connection 1 and gas ballast
valve 7 and operating fluid filler screw are closed.

ACHTUNG

– In non-stop operations check operating fluid daily,

otherwise whenever the pump is switched on;
topping up pump fluid is possible when the pump is in
final vacuum operations.

If there is a noticeable loss of pump fluid, the
casing and the radial shaft seals should be
checked for leaks (see Service Instructions).

4.2. Switching The Pump ON And OFF

The pump can be switched ON and OFF in any pressure
range. Maximum exhaust pressure 1.5 bar (absolute). Lowest
start-up temperature, in compliance with German Industrial
Standard DIN 28 426: +12°C.
On switching OFF (intake pressure < 750 mbar) the built-in
high vacuum safety valve to the vacuum chamber closes
automatically and the pump is vented.

The Working Of The High Vacuum Safety Valve

The automatically operating high vacuum safety valve 20 is
open when the equipment is vented. When the pump is
switched on, air intake is shut off via hydraulic pump 53
integrated in the pumping system and the safety valve
remains in the open position owing to the action of the
pressure spring.
At intentional or unintentional pump standstills, hydraulic
valve 23 opens the air intake owing to absence of hydraulic
pressure and presses valve head 24 against the vacuum side
by virtue of the air streaming in. The system closes vacuum
tight and simultaneously the pump is vented.
When the vacuum pump is switched on again, the intake of
air is shut off by hydraulic valve 23 and the inner area of the
high vacuum safety valve is evacuated. If the pressure in the
valve has fallen far enough that the force of spring 27 is suffi­cient to press valve head 24 against the pressure prevailing in
the system, the valve opens.

4.3. Pumping Dry Gases And Vapours

No special measures are necessary providing the correct
pump version is being operated (selection of operating fluid,
materials etc.).

4.5. Gas Ballast Valve (For Corrosive Gas
Processes)

Gas ballast valve 7 is equipped with a dosing unit 7.3 and a
flushing gas connection 7.4.
The dosing unit is closed when turned fully clockwise and
open when turned fully anti-clockwise. The amount of gas
can be set at any required rate from maximum to minimum
with a flow meter.

Gas ballast valve 7,
Standard version

Position: Closed Position: Open

Please note:

Flushing gas must be connected when operating corrosive
gas model pumps. The gas ballast valve must be open.
Flushing gas pressure may not exceed 1.5 bar. The type of
flushing gas is dependent on the medium being pumped. Our
specialists would be pleased to give advice regarding the
type and volume of flushing gas required.

When working with synthetic pump fluid, the
manufacturer´s directions for use must be
observed. If F5 is heated to over 250°C,
poisonous gases damaging to the respiratory

system are produced. F5 must not be allowed to
come into contact with tobacco products. When handling
chemicals, the relevant manufacturer´s instructions must be
followed. Pump fluid which have been enriched with toxic or
corrosive substances must be specially handled and all perti­nent regulations must be observed.

4.6. Silencer

Silencer 40 is a nozzle inside the pump housing and cannot be
altered; when dirty it should either be cleaned or replaced
(see Service Instructions).

4.4. Gas Ballast Valve (Standard Version)

To avoid the condensation of vapours in the pump, air is peri­odically fed into the working chamber at the beginning of the
compression phase via the gas ballast valve.

– Gas ballast valve 7 is shut when turning to the right to posi-

tion 0–0 and open when turning to the left to position 1–1.

Intermediate settings are not possible.
If the pumping process requires the connection of flushing
gas, an adapter connection G 1/8 can be provided for the gas
ballast valve (available on request).

To avoid condensation in the pump, vapours
should only be pumped off when the pump is
warm and with gas ballast valve open. Note
pump water vapour compatibility levels under

Section 8. Technical Data. When the process
has been completed, allow the pump to continue running for
about 30 minutes with open gas ballast valve for operating
fluid regeneration purposes.

5. What To Do In The Case Of Breakdowns?

Problem Possible Cause Remedy

Pump doesn't attain final pressure • Pump dirty • Clean the pump

• Operating fluid dirty • Operate pump for a longer period with open gas
ballast valve or change operating fluid

• Leak in system • Repair leak

Unusual operating noises • Silencer dirty • Clean the silencer (see Service Instructions).

• Pump system damage • Request repair by PFEIFFER Service

Pump doesn't start • Mains power missing • Check mains voltage and motor switch

• Ambient temperature <12 °C • Warm up pump

• Dirty pump stages • Request cleaning by PFEIFFER Service

• Damaged pump system • Request repair by PFEIFFER Service

6. Maintenance

When carrying out servicing work, take the following
precautions:

Always ensure the pump cannot be switched
on when carrying out any work on the pump. If
necessary, remove the pump from the system to
carry out inspection work.

➡ Only dismantle the pump as far as is necessary in order to

repair defects.

➡ Dispose of used operating fluid in compliance with local

regulations.

➡ When working with synthetic operating media, toxic

substances and substances contaminated with corrosive
gases, the relevant instructions governing their use must
be observed.

➡ Only use benzine or similar agents for cleaning pump

parts. Do not use soluble cleaning agents.

6.1. Replacing The Operating Fluid

The rate of deterioration of the operating fluid depends on the
pump applications.
➡ The level of deterioration of organic operating fluids (for

example P3) can be read off from the colour scale in
accordance with DIN 51578 on the supplementary sheet
PK 800 219 BN/B, on request.
– The colour scale enables precise colour determination.

➡ Fill a specimen in a test tube or some similar vessel and

test by holding against the light.

➡ Where the discolouration is dark yellow to red brown

(equivalent to 4 ... 5 on the scale) change operating fluid.

Where organic operating fluids, for example P3,

are involved, the operating fluid should be
changed at least once a year!

Replacing The Operating Fluid

➡ Switch off the pump.
➡ Unscrew operating fluid drain screw 4 and drain operating

fluid.

The operating fluid temperature can be as high
as 80 °C. During maintenance and repair work,
process related toxic gases and vapours can
escape from the operating fluid which may

become contaminated with harmful substances
(radioactive, chemical etc.).
Disposal of used operating fluid is subject to the relevant
regulations.

➡ Screw in operating fluid drain screw 4.
➡ Allow pump to run for about 10 seconds with open vacuum

flange.

➡ Drain off remaining operating fluid.
➡ In the case of serious contamination, the operating fluid

will have to be changed several times.

➡ Screw in operating fluid drain screw 4 with O-ring 49.
➡ Fill in fresh operating fluid and check level as per

section 4.1.

Operating fluid can contain substances from

the medium pumped. Operating fluid must be

disposed of in accordance with the local

respective regulations.

Please request safety instruction data sheets for operating
fluids from PFEIFFER or download from the INTRANET/
INTERNET.

Any other repairs may only be carried out by qualified personnel in conjunction with the service instructions.

9

➡ Fill up pump with fresh operating fluid: filling level - upper

end of sight glass 5.
If this amount of operating fluid is filled in, the level is
extremely high but this is necessary to protect all parts of the
pump against corrosion.

Before operating, the operating fluid must be
reduced to its normal level.

6.2. Shutting Down For Longer Periods

Should the pump have to be shut down for an longer period,
the complete pumping system must be adequately protected
against corrosion.

➡ Switch off pump.
➡ Unscrew operating fluid drain screw 4 and drain operating

fluid as per Section 6.1.

➡ Screw in operating fluid drain screw 4; keep an eye on the

position of the O-ring 49.

➡ Allow pump to run for about 10 seconds with open vacuum

flange .

➡ Drain off remaining operating fluid.
