tion.

2.2 Proper use

• The vacuum pump may only be used to generate a vacuum.

• Installation, operating and maintenance regulations must be complied with.

• Using accessories not mentioned in this manual is not permitted without autho-

risation from Pfeiffer Vacuum.

Improper use will cause all claims for liability and guarantees to be forfeited. Im-

proper use is deemed to be all use for purposes deviating from those mentioned

above, especially:

• Pumping of corrosive gases.

• Pumping of explosive media.

• Operation of the pump in potentially explosive areas.

• Pumping of gases containing impurities such as particles, dusts and condensate;

note the vapour compatibility levels of the pump.

pump must read and observe the safety-related parts of these operating instructions.

ÎAbsolute observe the safety information for vacuum pumps (PT 0300 BN) !

ÎThe operator is obligated to make operating personnel aware of dangers originating

from the vacuum pump, the pumped medium and the entire system.

NOTE

CE conformity

The manufacturer's declaration of conformity becomes invalid if the operator modifies

the original product or installs additional components.

ÎFollowing installation into a plant and before commissioning, the operator must

check the entire system for compliance with the valid EU directives and reassess it

accordingly.

Transport and storage

3 Transport and storage

3.1 Transport

Transport instructions

ÎRemove the locking cap from the vacuum flange immediately before connec-

ting!

– Check the protective strainer, paying attention to the o-ring.

ÎUse only the crane eye sideways at the operating fluid separator to lift the pump.

Fig. 1: Transporting the pump

3.2 Storage

ÎCheck that all the openings on the pump are securely closed.

ÎStore the pump in a cool, dry place; preferably at room temperature (approx.

20°C).

– For a longer period of storage, seal the pump in a PE bag with drying agents

enclosed.

– For a period of storage longer than one year, it is recommended to carry out

maintenance and change the operating fluid.

Product description

4.2 Function

The UnoLine™ series pumps are oil-sealed, single stage operating rotary vane

pumps with air cooling and circulatory lubrication. A vacuum safety valve in the

intake flange closes the intake line automatically and prevents operating fluid back-

streaming when the pump is switched off. The outlet is via an operating fluid sep-

arator (ONF) with integrated oil mist filter. In addition there is an oil filter in the op-

erating fluid separator cleans the operating fluid (dependent on the pump model).

The pumps are appropriate for operations in process technology in the food pro-

cessing, and packing industries and the metallurgical field.

The pumps can also be used for the purpose of generating centralized vacuum in

hospitals. The standard UnoLine™ pumps have been designed for non-stop or in-

termittent operations.

5 Installation

5.1 Setting up the pump

Installation location Observe the following requirements when setting up the pump:

• Note the load-bearing capacity of the mounting surface.

• Maximum installation altitude 2000 m (above mean sea level)

• Permissible ambient temperature: +12 ... +40°C

• Maximum relative humidity 85%

ÎFill up with operating fluid before operating the first time (see p. 14, chap. 5.5).

– Amount and type according to rating plate

ÎAlways place the pump on a firm, even surface.

– Where stationary installation is involved, anchor the pump on site.

Installation

ÎWhen installing the pump in a closed housing, ensure there is sufficient air cir-

culation.

– Sightglass and gas ballast valve must be visible and readily accessible.

– Voltage and frequency information given on the motor rating plate must be

visible.

5.2 Connecting the vacuum side

ÎBefore attaching the piping at the vacuum flange remove locking cap and insert

protective strainer with the respective O-ring.

ÎThe connection between the pump and the recipient should be kept as short as

possible.

– Depending on the pump type, use metallic hoses or PVC hoses with flange

connections.

– Separators, filters etc. may be installed upstream to protect the pump (see ac-

cessories). However, please observe the loss of pumping capacity due to the

conductivity of the accessories.

5.3 Connecting the exhaust side

ÎChoose the cross-section of the exhaust line to be at least the size of the nominal

connection diameter of the vacuum pump's exhaust connection.

ÎPiping to the pump must be suspended or supported.

– Forces from the piping system must not be allowed to act on vacuum pumps.

ÎLay piping from the pump, sloping downward so that no condensate can flow

back into the pump; otherwise fit a condensate separator.

– If an air trap is created in the system then a device for draining condensation

water must be provided at the lowest point.

CAUTION

High pressure in the exhaust line!

Danger of damage to the seals and danger of the pump bursting.

ÎInstall the line without shut-off valves on the exhaust side.

ÎIf there is danger of a build-up of excess pressure (> 1500 mbar abs.) in the lines,

observe all official accident prevention safety regulations.

ÎIf the exhaust gases are being extracted, the exhaust pressure must be at least

250 mbar greater than the pressure at the intake side.

WARNING

Emission of toxic substances from the exhaust!

Danger of poisoning from emitted gases or vapours, which can be detrimental to

health and/or can pollute the environment, depending on the particular application.

ÎComply with the applicable regulations when working with toxic substances.

ÎOnly officially approved filter systems may be used to separate out these

substances.
