IMPORTANT SAFETY CONSIDERATIONS 

The Leybold EcoDry M, oil-free vacuum pump is designed for safe and efficient operation when used properly and in
accordance with this manual. It is the responsibility of the user to carefully read and strictly observe all safety precau-
tions described in this section and throughout the manual. This product must be operated and maintained by trained
personnel only. Consult local, state, and national agencies regarding specific requirements and regulations. Address
any further safety, operation and/or maintenance questions to your nearest Leybold Vacuum office.

Warning   

Failure to observe the following precautions could result in serious personal injury:

• Before beginning with any maintenance or service work on the EcoDry M, disconnect the pump from

all power supplies.

• Do not operate the pump with any of the covers removed. Serious injury may result.

• If exhaust gases must be collected or contained, do not allow the exhaust line to become pressurised.

• Make sure that the gas flow from the exhaust port is not blocked or restricted in any way.

• The standard version of the EcoDry M is not suited for operation in explosion hazard areas. Contact us

before planning to use the pump under such circumstances.

• Before starting up for the first time, the motor circuit (3 phase) must be equipped with a suitable pro-

tective motor switch. Please take note of the information in these Operating Instructions or on the elec-
tric motor (wiring diagram).

• The EcoDry M is not suited for pumping of:

- combustible and explosive gases or vapours
- radioactive and toxic substances
- pyrophorous substances.

• The EcoDry M must be integrated in the system control arrangement so that the pump can not run-up

automatically after it has been shut down by the temperature switches in the motor. This applies equal-
ly to emergency shut-down arrangements. After having determined the fault cause, the pump should
be switched on manually again.

• Avoid exposing any part of the human body to the vacuum.

• Never operate the EcoDry M without a connected intake line or blank flange.

• The location at which the EcoDry M (including its accessories) is operated should be such that angles

over 10° from the vertical are avoided.

• The location of the EcoDry M should be such that all controls are easily accessible.

• Under certain ambient conditions the EcoDry M may attain a temperature of over 80 °C (176 °F). There

then exists the danger of receiving burns.
Note the symbols on the pump pointing to the hazards, and in the case of a hot pump wear the requi-
red protective clothing.

• The noise level produced by the EcoDry M without gas ballast is < 59 dB(A) with silencer or connec-

ted exhaust line.
Make sure that suitable protection measures are taken to protect the hearing.

• Before operating the EcoDry M with atmospheric gas ballast check first compatibility with the pumped

media so as to avoid hazardous conditions during operation right from the start.

• Before commissioning the EcoDry M, make sure that the media which are to be pumped are compa-

tible with each other so as to avoid hazardous situations.
All relevant safety standards and regulations must be observed.

Warning

GA 01.701/5.02 -07/01

• It is recommended to always operate the EcoDry M with a suitable exhaust line which is properly

connected. It must slope down and away from the pump.

• When moving the EcoDry M always use the allowed means.

A lifting eye is provided as standard on the pump.

Failure to observe the following precautions could result in damage to the pump:

• Do  not  allow the ingestion of small objects (screws, nuts, washers, pieces of wire, etc.)

through the inlet port. Always use the screen which is supplied with every pump.

• Do  not  use the pump for applications that produce abrasive or adhesive powders or 

condensable vapours that can leave adhesive or high viscosity deposits. Please contact Leybold Sales
or Service to select a suitable separator. Also please contact Leybold Sales or Service when planning
to pump vapours other than water vapour.

• This pump is suited for pumping water vapour within the specified water vapour tolerance limits.

• Avoid vapours that can condense into liquids upon compression inside the pump, if these substances

exceed the vapour tolerance of the pump (> 25 mbar for water vapour).

• Before pumping vapours, the EcoDry M should have attained its operating temperature, and the gas

ballast should be set to position I - III (position 0 = closed, position 3 = max. water vapour tolerance, 25
mbar).
The pump will have attained its operating temperature about 30 minutes after starting the pump. During
this time the pump should be separated from the process, by a valve in the intake line, for example.

• Be sure that the lines (exhaust and intake lines) and other vacuum connections are clean and free of

oil. This applies in particular if oil sealed pumps were used before. The conditions must be checked
before commissioning, and in the case of deviations you should contact your nearest Leybold Service
office.

• In the case of wet processes we recommend the installation of liquid separators upstream and down-

stream of the pump as well as the use of the gas ballast.

• The exhaust line should be laid so that it slopes down and away from the pump so as to prevent con-

densate from backstreaming into the pump.

• In order to prevent the transfer of vibrations from the EcoDry M to other parts of the system we recom-

mend the use of corrugated hoses or compensators on both the intake and the exhaust sides. In case
you need any further information please get in touch with Leybold.

• Operate the EcoDry M only in the orientations detailed in the dimensional drawings (see page 8). For

the purpose of reducing the transfer of vibrations to the building we also recommend the use of vibra-
tion absorbers (see accessories for the EcoDry M).

This information will help the operator to obtain the best performance from the equipment:

• Normal amounts of humidity within the range of the pump’s vapour tolerance will not significantly affect 

pump performance when the gas ballast is active.

• With the pump switched off, the pressure in the pump will rise very slowly to the level of the exhaust

pressure (normally atmospheric pressure). The EcoDry M is not equipped with any vacuum protec-
tion means. Thus you must install a valve in the intake line which automatically seals off the intake port
of the EcoDry M when at standstill.

Introduction

GA 01.701/5.02 - 07/01

1 Introduction

EcoDry M pump provides a clean, absolutely oil-free
means of evacuation without the risk of hydrocarbon
contamination. The gas compression stages achieve
pressures as low as 2·10

-2

mbar (15 mTorr, 2 Pa). The

very low friction coating on the cylinders and on the
pistons allows maintenance-free continuous operation
for up to 2 years depending on the kind of application.
Please note the recommendations as to the applications
provided in these Operating Instructions.

1.1 Principles of Operation

1.1.1 Stages of Compression

The EcoDry M is equipped with three (M 15) or two (M
20) compression stages which are formed by three
pistons.

The gas to be pumped reaches the compression space
of the cylinder by means of slots formed in the walls of
the cylinders. These slots are uncovered by the piston at
bottom dead center and then covered again as the piston
ascends. The gas is compressed while the piston
ascends and exits the compression chamber through
large valves.

1.1.2 Sealing

At initially high pressures, gases may leak past the
piston from the compression chamber and into the drive-
unit housing (called ”blow-by”). However, the EcoDry M
drive-unit housing is designed such that blow-by gases
are drawn back into the cylinders and exhausted.

Moreover, the entire sealing system of the EcoDry M is
so designed that a low leak rate in the order of
< 1·10

-4

mbar · l · s

-1

is attained. The static seals made

of Viton and the PTFE radial shaft seals which are lubri-
cated with a grease which is free of hydrocarbons and
which are highly media compatible, reliably prevent the
exchange of gas between the EcoDry M and the 
surrounding atmosphere.

To avoid internal leakage reducing the pump perform-
ance, the cylinder and piston are manufactured to very
close tolerances, leaving almost no gap between them.
Additional sealing collars are provided towards the drive-
unit housing. Towards the outside the chamber of the
shaft is sealed off by a radial shaft seal.

1.1.3 Lubrication

The pistons are covered with a low-friction material. The
low friction coefficient of the PTFE lets it serve as a bea-
ring and seal without additional liquid lubricants.

Moreover, all rolling bearings are lubricated with a grea-
se which is free of hydrocarbons and they are separated
by a dry seal from the vacuum chamber within the pump.

1.1.4 Friction and Cooling

Due to the selection of the pump materials, the friction
(and therefore the heat generated) is kept very low. No
additional cooling is needed in normal applications.

When installing the pump in an enclosure
make sure that there is an adequate flow of
cooling air.

1.1.5 Eliminating Hydrocarbon 

Contamination

The risk of contamination by hydrocarbons is a major
concern with mechanical oil-sealed pumps because
liquid lubricants can stream back into the chamber to be
evacuated. The EcoDry M achieves high compression
ratios by using dry multiple-stage compression instead
of oil sealing, and absolutely no liquid lubricants are
used in the compression chambers.

• Refuse the shipment.

• Notify Leybold Vacuum immediately.

2.1.2 Unpacking the Pump

1. Open the top of the shipping crate.

2. Remove any packing materials.

3. The pump is equipped with a lifting eye, and should

only be lifted with this device.

2.1.3 Inspecting the Pump

Inspect the pump for damage.

If damaged:

• Notify Leybold Vacuum immediately.

• Retain the original shipping and packing materials.

• Wait for return authorisation from Leybold Vacuum.

• Return the pump in the original package via the 

original shipper.

2.1.4 Supplied Equipment

The EcoDry M is supplied with the following basic items:

• Pump with motor

• Separate dirt collecting sieve (dirt trap)

• Operating Instructions

• “Declaration of Contamination” form

The connection ports are sealed off before shipping with
sealing caps.

EcoDry M pumps equipped with a single phase AC
motor have a 1.8 m long mains cord and may be connec-
ted to the mains direct via the plug.

The AC motors are equipped with a built-in thermal
motor overload circuit breaker and a mains cord (1.8 m
long).

Country specific plugs USA, Japan, Euro are included. In
the case of the three-phase motors suitable motor over-
load protection and the connection to the mains power
supply must be installed resp. provided by the customer.

2.2 Installation

The EcoDry M pump is installed upright or horizontally
on the anti-vibration mounts provided.

Make sure that there is a clearance of at least 100 mm
to other components or pumps at every side to allow an
adequate air flow for cooling.

The EcoDry M pump is a complete unit. Listed below are
several optional accessories that will lead to more effi-
cient operation and prolong the useful life of the pump.

• Dust filter, liquid separator for the inlet

• Vibration absorbers

• Exhaust silencer

• Inert gas connection

2.2.1 Suggested Installation Procedure

The EcoDry M must only be operated in
such orientations where the axis of the
pump (crankshaft) runs horizontally.

Please accurately observe the following
safety information given in these Operating
Instructions.

1. Install in an open area with an ambient temperature

below 50°C (122 °F). If the pump must be installed in
an enclosed area, air-circulating fans may be neces-
sary to ensure adequate cooling.

2. Before connecting the EcoDry M to the intake and

exhaust lines please remove the shipping seals on the
pump’s intake and exhaust flanges. Connect the
chamber to be evacuated to the inlet flange of the
EcoDry M pump.

3. Use flexible stainless steel bellows in the piping to

reduce transmission of vibrations during operation.

4. Make sure pipe lines are adequately supported to

reduce stress on joints.

5. Install a vacuum gauge in the inlet line with a

vacuum-quality valve upstream of the gauge. This
allows the pump to be isolated from the system to 
monitor its proper performance.

GA 01.701/5.02 -07/01

6. Install the stainless steel screen (dirt trap) provided

over the inlet port to prevent the ingestion of small
objects that can damage the pump. The flow rate may
be somewhat reduced by the screen, but the protec-
tion it provides will prolong the life of the pump.

7. Make sure that the exhaust port is clean and

unobstructed.

Roughing lines and other vacuum connec-
tions must be clean, especially if previously
evacuated by oil-sealed mechanical pumps.

Make sure that the gas flow at the exhaust
port is not blocked or restricted in any way.

If the exhaust gases must be contained or
collected, do not allow the exhaust line to
become pressurised.

2.3 Operation of the Pump

Please note the safety information given on

page 4 and the subsequent pages.

The pump must only be started up after
having fully assembled it.

The exhaust line should be laid so that it
slopes down and away from the pump in
order to prevent condensed vapours from
flowing back into the pump.

During operation, the exhaust side must
always be open. Check any valves which
may be present in the exhaust line.
The max. exhaust backpressure must never
exceed 1200 mbar abs.

2.4 Electrical Connection

Make sure that the mains supply is turned
off when cables are connected.
The electrical connection should only be
performed by staff qualified in accordance
with VDE 0105 and following the guidelines
of VDE 0100.

The EcoDry M pump can be connected to different
mains supply voltages and frequencies (see Section 1.2,
Specifications) as well as page 12.

If necessary, change the jumper configuration in the
motor terminal box (3ph) to adjust the pump to the avai-
lable supply voltage.

Connect the pump to mains via a suitable protective
motor switch (see name plate), but do not turn on the
pump until all electrical and vacuum lines are connected.

2.4.1 EcoDry M with Single-Phase Motor

The EcoDry M may be connected directly to the mains
supply via the plug.

The cross section of the mains power sup-
ply cables should amount to at least 1.5
mm

2

.

In the case of the single phase AC motors
the direction of rotation is fixed and will the-
refore not need to be checked separately.

2.4.2 EcoDry M with Three-Phase Motor

Because of the principle of operation employed by the
pump the direction of rotation is not relevant.

If the thermal motor overload circuit breaker
of the pump has responded, the motor will
switch itself on automatically after the tem-
perature has dropped back to permissible
levels.

Application  Notes

3.3 Condensable Vapours &

Liquids

The EcoDry M pump is not suited for pro-
longed pumping of condensable vapours
above the specified water vapour tolerance.
Pumping of liquids is to be avoided and will
damage the pump.

• Normal amounts of water vapour in atmospheric air 

will not affect pump performance.

3.4 Use on Wet Processes

Do not allow direct ingestion of liquids into
the pump.
Note the vapour tolerance levels which
apply to this pump. In case of any questions
in this matter do not hesitate to get in touch
with Leybold Vacuum.

Generally the following applies:

• The lines connected to the pump should be so rated 

that no liquids can suddenly enter the pump.

• The chambers should only contain liquids having a 

low vapour pressure.

• Note the safety information provided in these

Operating Instructions.

13

GA 01.701/5.02 -07/01

Please also note the information provided
on potential hazards given on pages 4, 5
and the subsequent pages.

3.1 General Application

The EcoDry M is ideal for applications that require the
achievement of pressures as low as 2·10

-2

mbar 

(2 Pa, 15 mTorr ) without the risk of contamination from
liquid lubricants. The pump may be operated intermit-
tently as needed, or continuously for as long as 2 years
without maintenance. Owing to its freedom from hydro-
carbons and no compromise in performance, the EcoDry
M replaces single-stage oil-sealed rotary pumps in many
applications.

Do  not  use the pump for applications that
produce abrasive or adhesive substances
or condensable vapours that can leave
adhesive or high viscosity deposits.
Also the formation of thicker deposits
should be avoided since these too may form
adhesive or high viscosity deposits.

4 Maintenance

Under the operating conditions detailed, the EcoDry M is
capable of operating continuously for a period of two
years without any maintenance.

Since no operating means other than electric power are
required for operation of the EcoDry M, any maintenan-
ce regarding operating agents and consumption is not
required.

If in spite of this any unexpected maintenance becomes
necessary within this period, please get in touch with the
local Leybold Service.

When returning equipment to our Service please fill in
completely the “Declaration of Contamination” form.

If no such declaration is available to the
Service, any processing will not be possible
and the pump will possibly be returned to
the sender.

The EcoDry M must be packaged in such a
way that the pump can not be damaged
during shipping and so that no hazardous
substances may escape from the package.
