Using and principle of
pumping units
Drytel 1025 Series pumping units are a combination of vacuum
pumps:
- a hybrid or simple turbomolecular secondary pump.
- and a multi-stage diaphragm pump.
They allow the reduction of pressure of the vessel from atmospheric
pressure until low vacuum.
The inlet gases are compressed and exhausted at atmospheric
pressure.
Drytel 1025 Series pumping units are designed for pumping of gases
or of vapors and mustn’t be used for the liquid pumping.
However vapors emanated from liquids or solids can be pumped with
dilution by inert gases.
They are not designed for working as a compressor.
They are not designed for pumping gases at inlet pressure over
atmospheric pressure.


The Drytel 1025 Series are designed for various gases and can be
adapted to the application with accessories. For applications, see
section A 30.

Automatic air ballast
operating principle
Drytel Series
Powering up the solenoid valve opens it and introduces a calibrated
quantity of air via a nozzle parallel to the pumped gas.
Sintered metal disks protect the nozzle from dust or foreign bodies
carried by the gas or from the atmosphere.
The air inlet filter protects against dust or foreign bodies from the
atmosphere.
In case of accident or if the pump stops, a valve closes this inlet and
keeps the system anti-suckback.
For more efficiency, it is possible to use a dry neutral gas as a purge
gas.
See section B 30 Connecting the automatic gas ballast (option).
See section C 40 Using the automatic gas ballast (option).
When these condensable gases are pumped, depending on the
nature of the pumped gases, pressure and temperature conditions,
they may condense in the dead volumes of the primary pump.
When the pumping unit is at low pressure, the roughing pump is
at its ultimate pressure. The gases no longer pass through, its check
valves no longer open and the condensates remain inside the pump.
These condensates mix with dust and create a destructive abrasive
for the pump diaphragm.
The introduction of gas at the last stage of the pump has various
effects:
the dilution of the pumped gas and the reduction of the partial
vapor pressure of the residual gas in the pump.
it increases the compression of the pump and heats it, reducing
the risk of condensation by increasing of the temperature of the
internal pump.
it reduces in the last stage the partial pressure of the pumped
gas and it stops its condensation when the gas reaches the
atmospheric pressure.
in case of pumping at low pressure, when there is no flow, it
gives the possibility to open the valves and evacuate the dropless
and residual gases.

Gas and vapor
pumped
The chemical and standard Drytel 1025 are designed for various
gases and can be adapted to the application with accessories.
The gases pumped can be identify as follow:
1 - neutral or inert, air, nitrogen, CO2, rare gases or permanent
non reactive gases,
2 - gas containing condensable vapor, gases able to condense them
selves, gases able to polymerize,
3 - reactive and / or corrosive gases with : air, moisture or together
with material of the pumping line depending on the conditions...,
4 - oxidizing, reactive, in particular with hydrocarboned compounds
hydro-carbonés O2,O3 ,CO ,NO , NO3...,
5 - flammable or explosive, in mixture with a combustive
including oxygen like air.
This is the user and/or the OEM’s responsibility to avoid any explosive
mixture.
6 - toxic and / or asphyxiating,
7 - any possible combinations of them.
See page 3 , the chart «equipment choice depending on
application».
Use of the pumping
units
Drytel 1025 The standard Drytel 1025 are designed for pumping of neutral, inert
(air, nitrogen...) and permanent gases . The purges are not included.
However, if the pumped gaseous composition contains condensable
vapors, the gas ballast optional use of the group (unit pumping) may
be required.
The chemical Drytel 1025C are designed for pumping at low pressure
corrosive internal parts of the pump, as condensable vapors.
The high vacuum pump is equipped itself with a purge to protect the
mechanical part and its motor.
The roughing pump AMD4C may is equipped with a gas ballast (op-
tion) or a purge on line eshaust (customer’s furniture)
Warning, some gases can damage the pumping unit ( ex: NH4OH
damages FPM elastomer, some fluorine damage the Teflon...).

Precautions of use
The use of specific accessories allows the pumping of different vapors
and gases.
The purges decrease the reactivity of different gases and vapors.
They reduce the concentration of the pumped gases.
The gas ballast generates the thermodynamic conditions (tempera-
ture and concentration) necessary to avoid condensation or deposits
inside the pump.
During some applications, it is not possible to know what is really
pumped.
The vacuum outgassing of pumping line materials can generate
reactive gases (solvent, acid) which may change the nature of the
pumped gas mixture.
The gases or vapors at low pressure have a poor concentration and
are not very reactive. When the pressure is closer to atmosphere,
they can occur the saturation. Their reactivity can become important.
Listed below are different pumping cases, and recommended
technical solutions. (This list is not exhaustive).
The Drytel 1025C version are made to pump on corrosive gas traces.
The user and /or OEM are ultimately responsible for operating the equipment
in a safe manner. The manufacturer has no control over the types of gases
exposed to this pump. This is the user and/or the OEM’s responsibility to
follow the necessary safety requirements.
Frequently process gases are toxic, flammable, corrosive, explosive and/or
otherwise reactive.
Toxic gases can cause serious injury or death. Operators and users must
take the appropriate safety recommendations to prevent injury. Consult the
responsible department for instructions and safety information.
Hazardous gases through the pump can cause serious injury or death.
It’s mandatory by regulations to connect the pump’s exhaust to a facility
hazardous gas exhaust system which incorporates appropriate filters,
scrubbers, etc. This system must meet all air and water regulations. Check
that pump is correctly connected to the equipment ( B 60).
