1 Safety and compliance

1.1 Denition of Warnings and Cautions

NOTICE:

For safe operation from the start, read these instructions carefully before you install or

commission the equipment and keep them safe for future use.

Read all the safety instructions in this section and the rest of this manual carefully

and make sure that you obey these instructions. The equipment must only be

operated and maintained by trained personnel in the proper condition and as

described in this instruction manual.

Obey local and state requirements and regulations. If you have any questions about

safety, operation or maintenance of the device, please contact our nearest subsidiary.

Important safety information is highlighted as warning and caution

instructions. Obey these instructions.

WARNING:

If you do not obey a warning, there is a risk of injury or death. Different symbols are

used according to the type of hazard.

2 Important safety information

WARNING: HAZARDOUS VOLTAGES

Risk of electric shock. Disconnect the unit from the power supply before starting any

work. Take appropriate precautions to make sure that the pump will not start.

WARNING: HAZARDOUS GASES

Risk of injury or damage to the equipment. If the pump has pumped hazardous

gases, it will be absolutely necessary to determine the nature of the hazard involved

and take the appropriate safety precautions. Observe all safety regulations. Take

adequate safety precautions prior to opening the intake or exhaust port.

WARNING: TRANSPORTATION SAFETY

Risk of injury or damage to the equipment. The pump must be packaged in such a

way that it will not be damaged during shipping, and so that no harmful substances

can escape from the package.

CAUTION: OPERATION SAFETY

Risk of damage to the equipment. Do not open the pump to condensable vapours

until it has reached the operating temperature. Pumping process gas with a cold

pump results in vapours condensing in the oil.

CAUTION: INTERNAL CONDENSATION

Risk of corrosion. When vapour are pumped, do not switch off the pump immediately

after the completion of the process because the condensate dissolved in the pump

oil may cause changes or corrosion. To prevent this, continue to operate the pump

with open gas ballast valve and closed intake port until the oil is free of condensate.

We recommend you to operate the pump in this mode for at least 30 minutes after

completion of the process.

For processes with a high proportion of condensable vapours, the intake line

must be opened slowly only after the pump has reached the operating

temperature.

One sign of condensation of vapours in the pump is a rise of the oil level

during the operation of the pump. During pumping, vapour may dissolve in

the oil.

In cyclic operation, do not switch off the pump between the cycles and

continue to run with the gas ballast valve open and intake port closed (if

possible, through a valve). The power consumption is minimal when the

pump is operating at ultimate pressure.

If all vapour are pumped off from a process (for example, during drying), the

gas ballast valve can be closed to improve the ultimate pressure.

3 Description

3.1 Design and function

The pumps are single-stage, oil-sealed rotary vane vacuum pumps. The

anti-suckback valve, gas ballast valve (optional), exhaust lter,oil return

circuit and oil cooling oil are integrated functional elements. The pumps are

driven by a directly anged motor.

The rotor is eccentrically installed in the pump cylinder (stator) and has three

vanes which divide the pump chamber into several compartments. The

volume of these chambers varies with the rotation of the rotor.

As the rotor rotates, the intake portion of the pumping chamber expands

and sucks gas through the intake port. The gas passes through the dirt trap

and open anti-suckback valve and enters the pump chamber. As the rotor

rotates, the vane separates part of the pump chamber from the intake port.

This part of the pump chamber is reduced and the gas is compressed.

Slightly above atmospheric pressure the gas is expelled from the chamber

through the exhaust valve.

The oil injected into the pump chamber seal, lubricate and cool the pump.

The oil and the compressed gas is coarsely trapped in the oil case by

deection. Fine ltering of the oil in the exhaust lter element is done, this

reduces the proportion of oil in the exhaust gas below the visibility threshold

(over 99.9% entrapment rate).

Oil trapped in the exhaust lters is returned to the inlet chamber through the

oil return line. To prevent the gas ow at the atmospheric pressure from the

oil reservoir into the intake port, the oil return line is controlled by a oat

valve.

The oil cycle is maintained by the pressure difference existing between the

oil case (pressure above or equal to atmospheric pressure) and the intake

port (pressure below atmospheric pressure).

A fan running on the pump shaft generates the necessary cooling air. The oil

cools down through a radiator.

Water cooled pumps with an oil-water heat exchanger are also available (as

specic variants).

By opening the gas ballast valve, a controlled amount of air (gas ballast)

enters into the pump chamber. This gas ballast prevents condensation (up

to the limit of water vapour tolerance specied in the Technical data on

page 11) when pumping the condensable gases or vapour.

There are different types of gas ballast :

▪Standard gas ballast (7 m3/h). This gas ballast corresponds to the

most important part of applications.

▪Large gas ballast (18 m3/h) as a variant or accessory is intended for

the applications where more vapours of condensable gases could

come into the pump.

▪Gas ballast with electromagnetic valve (6 m3/h). This kit is intended for

being mounted on pumps on which the gas ballast can be driven by

an electromagnetic valve applied at 24 V d.c. Refer to Pumping of

condensable gases and vapour through gas ballast on page 26.

The gas ballast ows are indicative and valid at ultimate pressure.

Description

Anti-suckback valve prevents the unintentional venting of the vacuum

chamber and an oil suckback when shutting down the pump. In applications

where an oil suckback must be avoided by all means, it is recommended to

install a safety inlet valve.

The pump is supplied with drive motor in ready-to-use condition. It is

supplied with lled in oil. PFPE versions are delivered empty.

Specic variants of the pump are delivered with different oils. The oil type is

indicated on the pump. Do not use another oil than specied, no warranty

claims would be accepted if use with different oil. The connection ports are

blanked off by plastic protective caps. Take these caps away before turning

on the pump.

3.2 Range of use

The pump is designed for pumping the inert gases in the range of vacuum,

between atmospheric pressure and ultimate pressure of the pump.

The pump are not designed for pumping of aggressive, corrosive, ammable

or explosive gases. In the presence of aggressive, ammable, corrosive or

explosive gases, contact us.

The pumps are not designed for working in ammable or explosive

environment.

The pumps are not suitable for pumping liquids or media which contain

dust. Protective measures must be introduced.

Before pumping oxygen at concentrations exceeding the concentration in

the atmosphere (> 20% the pump must be modied, degreased and a

special oil (such as PFPE) must be used. Contact us for information.
