Using and principle of
pumping units
Drytel 1025 pumping units are a combination of vacuum pumps:
- an hybrid or simple turbomolecular secondary pump.
- an a multi-stage diaphragm pump.
They allow to reduce the pressur of the vessel from atmospheric
pressure until low vaccum.
The inlet gases are compressed and rejected at atmospheric pressure.
Drytel 1025 pumping units are designed for the pumping gases or
vapors and must not be use for the liquid pumping.
Howener vapors emanated from liquids or solids can be pumped when
diluting them with inert gases.
• They are not designed for working as compressor.
• They are not designed for pumping gases at inlet pressure higher
than atmospheric pressure.

Description
Automatic air ballast
operating principle
Principle diagram
Powering up the solenoid valve opens it and introduces a calibrated
quantity of air via a nozzle parallel to the pumped gas.
The sintered metal PORAL 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 pump anti-suck back.
For more efficiency, it is possible to use a dry neutral gas as a purge
gas.
See sheet B 30 Connecting the automatic air ballast (option)
See sheet C 40 Using the automatic air ballast (option)
When 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 primary pump is at
the limit vacuum. The gases no longer pass through, its check valves
no longer open and the condensates remain inside.
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:
ythe dilution of the pumped gas and the reduction of the partial
vapor pressure of the residual gas in the pump.
yit increases the compression of the pump and heats it, reducing the
risk of condensation by increasing of the temperature of the
internal pump.
yit reduces in the last stage the partial pressure if the pumped
gas and it stops its condensation when the gas reaches the
atmospheric pressure.
yin case of pumping at low pressure, when there is no flow, it gives
the possibility to open the valves and evacuate the residual gases.

Before powering up, the user must study the manual and follow
the safety instructions.
Our products are designed to comply with current EEC regulations.
Any modification of the product is liable to result in non-compliance
with regulations, or affect the EMC (Electromagnetic compatibility)
performances and safety of the product.
Alcatel declines responsibility for consequences resulting from such
an intervention.
Products’ EMC performances are subject to the installation being
carried out in compliance with the applicable EMC regulations.
Particularly in environments subject to interference, it is essential to:
- use shielded links and connections for interfaces,
- stabilise the power supply line with a mesh from the power supply
source up to a distance to 3 m with respect to the product input.
The pumping units must be connected to an electrical installation in
compliance with decree 88 - 1056 of 14th November 1988.
Decontamination – product dismantling
According to the regulations 2002/96/CE about Waste of electrical
and electronical equipments, and 2002/95/CE about Restriction of
Hazardous substances, the manufacturer provides a recycling paid
service for the end-of-life of waste electrical and electronic equipment.
Any obligation of the manufacturer to take back such equipment shall
apply only to complete not amended or modified equipment, using
Alcatel original spare parts, delivered by Alcatel, containing i.e. all its
components and sub-assemblies.
This obligation will not cover the shipping cost to an Alcatel take back
facility.
Before returning the product, fill in the safety questionnaire, attach it to

GB 00877 - Edition 02 - January 2007
Before any maintenance operation on a product performed by a
maintenance operator not qualified on safety regulations (EMC,
electrical safety, chemical pollution, etc.), shut off the product from its
different power sources (electricity, compressed air, etc.).
It is dangerous to access the rotor of a turbomolecular pump on
which the intake is not connected.
Even if the pump is not powered, it may be driven by another pump
in operation.
Severe cuts may be caused on contact.
Before working on the pumping unit, it is recommended to:
- stop the pumping unit (main switch set 0),
- wait for all the components to stop,
- disconnect the mains power supply cable.
The performances and operating safety of this product can only be
guaranteed if it is used in compliance with its normal use.
Make sure that the chambers or confinements connected to the
pumping unit inlet can withstand a negative pressure of 1 bar with
reference to atmospheric pressure.
Check that the pumping unit is connected correctly to the equipment.
Do not move or induce a shock on a pump in operation. This could
result in a risk of crash.
When the main switch is set to 0, some electrical connections may
still be live.
Electrical shocks may cause severe injuries.
Before working on the pumping unit, it is recommended to
disconnect the mains power supply cable.

The pumping units are designed so as to prevent thermal risks for
the user’s safety.
However, particular operating conditions may induce temperatures
justifying particular caution on the part of the user (outer surfaces >
70 °C on exhaust connections).
Burns may be caused on contact.
Wear protective gloves before repair work.
Before executing maintenance operations, it is necessary to verify the
pumping conditions: toxicity, corrosion of the pumping gases.
The tightness of the product is guaranteed, when leaving the factory,
for normal operating conditions.
If hazardous or corrosive gases are pumped, the user is responsible
for ensuring the quality of tightness of the installation. This installa-
tion must prevent an over pressure in the pumping circuit.
The manufactor has no control over the types of gases passing
through this pump. Frequently, process gases are toxic, flamma-
ble, corrosive, explosive or otherwise reactive. Since these gases
can cause serious injury or death, it is very important to plumb the
exhaust of the pump to the facility’s hazardous gas exhaust system
which incorporates appropriate filters, scrubbers, etc., to insure that
the exhaust meets all air regulations.
Check that pump is correctly connected to the equipment.
Always connect the AMD4C pump exhaust to an exhaust extraction
system.
When powering up an item of equipment containing capacitors
loaded at over 60 VDC or 25 VAC, precautions must be taken at the
connector pin access.
Electrical shocks may cause severe injuries.
Before working on the pumping unit, it is recommended to wait 1
minute after setting the main switch to 0.

The pumping units must be used only in the industrial aera, in
comptiance with the standard EN din 294 table 4 for persons over
14 years.
The pumping unit can pump air with steam. It must not pump water,
other liquids, fumes, corrisive flammable gases. The pumpin unit
must not be operate in the aeras where then is a exploision risk.
Contact center service to adapt the pumping unit.
For safety reasons, any accessories connected to the inlet and ex-
haust must be made of materials compatible with pumped gases.
Ensure that the gases being used are compatible with pump’s mate-
rials. See sheet A 20
When the diaphragm pump is new, or has been in storage for a
shutdown period of 2 months or more, we recommend to switch on
the diaphragm pump for approximately 5 min. at atmospheric pres-
sure, then 10 min. at limit pressure.
This will evacuate potential moisture built up in the pump.
