• Only perform work on the motor during down-
time.
• Disconnect the motor from the compressed air
during all assembly and maintenance work.
• After completing all the work on the motor,
remount the safety devices in accordance with
specications.
2.2 Proper use
A compressed air driven drum and container pump
comprises motor and pump tube to suit the particu-
lar application. Application of the compressed air
motors MD1xL and MD2xL in explosive hazard areas
orforpumpingammableliquidsisonlyallowed
in combination with a pump tube approved for
category 1/2 G.
• Motor may only be operated with pump tube.
• The motor must not be immersed in the liquid
being pumped.
• The motor can be used in the following environ-
ment:
- temporarily outdoors without protection from
weathereects
- on roofed surfaces
- in open and closed rooms
- in explosive hazard areas

If the product and supplied accessories are used for
other purposes than the intended purpose, it is the
responsibility of the user to check the suitability and
admissibility.Productusenotconrmedinwriting
by the manufacturer absolves the manufacturer of
any liability.
The manufacturer is not liable for consequences of
incorrect treatment, use, maintenance, servicing
and operation of the appliance, as well as normal
wear and tear. The same applies if faults arise from
modicationsorcongurationsonthepartofthe
user not authorized by the manufacturer.
Prevention of obvious
misapplication (examples)
• Motor may only be operated with correctly
mounted pump tube.
• Motor may only be used in permissible explo-
sion hazard area
• Use suitable compressed air supply
• Do not connect the compressed air supply
while the engine is switched on
• Do not immerse the motor in the liquid being
pumped
• Do not drive inadmissible devices with the
motor
• Do not allow the motor to be operated by
children or people in need of protection
• Do not use improper accessories
• Do not use improper or inadmissible spare
parts
• Observe maintenance intervals
2.3 Specic danger
Explosion hazard area
!DANGER
Danger of explosion from use in an explosion
hazard area!
Whenpumpingammableliquids,theoperational
safety regulation and the following points have to
be observed:
• Compressed air motors are non-electrical oper-
atingappliancesnotrequiringocialapproval
when used in zone 1.
• The motors are therefore suitable for driving
explosion proof Lutz drum- and container pumps
Class I, Group D and C.
• Application restrictions are depending on the
respective pump tube (→operating instructions
pumptube).
• Only authorized for mobile use.
• Connect equipotential bonding (→chapter9).
• Useconductivepressurehosesonly(→operating
instructionspumptube).
• The pump motor must remain outside the drum
or container.
• Operating pressure must not exceed 72,5 psi
(5bar).
• The temperature of the compressed air supplied
must not exceed the max. permissible ambient
temperature.
• Motor and pump tube operation must be con-
trolled.
• Donotoperatethemotorwithammablegases.
• Prescribed inspection periods: Grooved ball
bearing and vane, both have to be exchanged
at latest after 1.000 operating hours.
• The presence of strong charge-generating
processes, in particular the arrangement within
transported dust and within a distance of 1 m
from high-voltage electrodes, must be excluded.

4. Starting up
4.1 Compressed air connection
!WARNING
Danger of injury due to uncontrolled restarting of the motor!
►Switchingothemotorbeforeconnectingthecompressedair.
Fig. 1
Function and service life largely depend on the condition and pressure of the compressed air supplied.
Excessive moisture or dirt particles in the compressed air will destroy the motor. A high percentage of
condensateinthecompressedairwillcauseaslightrustdepositinthemotorandtheairoutletmuer
will get covered by ice during air expansion.
Therefore, when starting the compressed air motor, observe the following items (→Fig.1):
• Before connecting the motor to the compressed air supply, clean the compressed air line and the hose
by blowing out with low pressure to remove any dirt particles from the line. Wear safety goggles, hold
thelinetightanddonotstandintheareaoftheairow.
• Mainairlines(6)requireaslightinclinationofatleast1%inthedirectionofowsothatcondensation
watermaybedrainedthroughavalve(7)atthelowestpoint(manuallyorautomatically).
• Branchpipesshouldbeconnectedpointingupwards(5)inthecaseofahorizontalmainline(6)-and
inthecaseofaverticalmainline(4)notatthelowestpoint.Thus,anycondensationwatercollectedin
themainlinewillbepreventedfromowingintothebranch.

• Usemaintenanceunits(3)consistingofairlter
and oiler. The oiler is not necessary for motors
MD1xL and MD2xL, but is recommended for
longerservicelife.Themotorpoweris10-20%
lower with non lubricated air than with lubricated
air.
• Install the maintenance unit with an air connec-
tion of at least G 1/4 in the immediate vicinity of
thecompressedairmotor(1).Usearesin-free
and acid-free mineral oil with a viscosity of 20 to
30cSt(20to30mm²/s)intheoiler(3).Theoil
consumption should be 1 drop per minute as a
minimum.
• Theair lter(3)requiresregularmaintenance
during which the trapped condensation water
isdrainedandthelteriscleaned.
• The compressed air motor will achieve maximum
performanceat87psi(6bar).Thepressurein
thepneumaticsystemexceeding87psi(6bar),
apressureregulator(3)mustbeinstalled.Ad-
justmentofthepressureregulator(3)mustbe
eectedwiththemotorrunning.
• Installanairhose(2)of1/2”(13mm)inside
diameter between maintenance unit and com-
pressed air motor to minimize the pressure
losses.
• Use a stop valve in the pressure line in order
to connect and disconnect the motor without
pressure.
• Note the resulting pressure loss when using
quick-action couplings.
Recommendation for compressed air supply
• Theclassicationofthecompressedairquality
can be taken from ISO 8573-1: 2010.
• Standard values of compressed air quality are
e.g. to be found in VDMA 15390-1: 2014-12.
• For lubricated air, a minimum compressed air
quality by ISO 8573-1: 2010 [-: 4: 4] is recom-
mended.
• For non lubricated air, a minimum compressed
air quality by ISO 8573-1: 2010 [6 3: 3] is recom-
mended.
• Excessive water contentin the compressedair can
cause freezing of the water particles. This may be
the cause for damaging the vanes or clogging the
muer,whichmayaecttheperformanceofthe
motor.
4.2 Assembly of pump tube to the
motor
3Motorisswitchedo
►Connect the motor with the pump tube.
►Turn the motor slightly to ensure that the
driver (→Fig.2,Item1)engagesinthe
coupling
(→Fig.2,Item2).
►Firmly connect the motor and pump tube by
meansofthehandwheel(right-handthread)
(→Fig.2).

5. Operation
!WARNING
Danger of rolling-up and pulling-in of objects!
►Do not put any objects in the opening for the
coupling control (→Fig.4).
►Donotworkonthemotorwiththinandloose-t-
ting gloves.
!WARNING
Danger of injury due to uncontrolled restarting
of the motor!
►The pump must not be left unattended while in
operation.
►If the power supply fails, the motor must be
switchedo.
5.1 Controlling compressed air
motor MD1xL
►Forswitching-on/othemotor,insertacheck
valve in the compressed air line (e.g. ball valve
fromLutzaccessories).
5.2 Controlling compressed air
