General
Thank yo u for choosing a high quality pump from Eu rolube Equipment AB Swe den. The 10:1 oil pu mp featu res an unique air
motor for q uiet an d quick servi ceability. Recomme nded fo r heavy duty un its and l arge pipe inst allations. Pl ease re fer to the s ales
catalogue for detail s on accessor ies. O r visit our websi te, ww w.eurolube.com.
The pump is suitable for s imult aneou s fluid distribution to multipl e dispe nse poi nts, or for pumping to distance s of up to 90 m
(30 0 ft) .
The air motor features a precision air va lve mechanism with dua l valve ports fo r improve d high sp eed br eathing. It als o conta ins a
positi ve trip de tent spool mec hanis m that eli minate s stalling (b lowing a ir) by preventing t he pump f rom stop ping be tween strokes.
It has a sim ple yet du rable construction with all internal par ts lub ricated at the fa ctor y using a life-te sted syn thetic grease.
The pumping as sembl y features a sta inles s pump ro d for superior wear and c orrosion resista nce. Th e pump’s exte rior is
constructed from aircraf t grade extru ded alu minum for an outstanding stre ngth and relia bilit y. The pump a lso has h igh qua lity
seals a nd is des igned f or long -term du rabil ity and ease of s ervice. The pump is also equipped with internal pr essure relie f to
protec t the system from therma l expansion.
A pump’s ability to deliver grease is b ased on the pressure ( bar/psi) a nd quan tity of a ir supp lied to th e air- motor a nd the am ount of
materi al disc harge ( back ) pres sure to be overcom e within the syste m.
WARNING! Do NOT use so lvent s or othe r explo sive flu ids. A n explo sion can res ult in th e pump wh en alumini um and z ink pa rts
come in c ontac ts with c ertain solvents . Never p oint a co ntrol valve at a ny por tion of yo ur bod y or anot her pe rson . Accid entia l

PUMP INSTALLATION
WARNING: Attach a proper ground wire to
the pump grounding lug (item 52, p.10) before
!
starting the pump.
NOTE: Pump performance will be degraded
by air or uid threaded connections which are
!
not air-tight. Use Teon™ tape or other suitable
means to achieve a complete thread seal.
PUMP OPERATION
CAUTION: Read all limitations which apply
to selection of uids which may be pumped by
!
this product. Do not pump a uid which is not
specied to be compatible.
CAUTION: Always read and follow fluid
manufacturers' recommendations regarding
!
proper use of protective eye wear, clothing
and respirators.
Provide a d rop-te e fitting, 3/4” size or lar ger, in the ne arby ai r suppl y pipeline. From that tee, install the following pump air line assembly:
pipe bushing or a dapter (to bring the line drop size to 3/4” male)•
1/2” pip e drop to pu mp level•
1/2” pip e elbow•
1/2” air F-R-L•
1/2” air s hutof f ball valve (having an air relief vent when close d)•
1/2” to 3/8” reducer a nd a 3/ 8” x 3 ft. a ir hose•
3/8” air line c ouple r and nip ple.•
Attach the air nipple to the air inlet port of the pump. During assembly of the air supply line, be sure to clean out all foreign materials
before making connection to the pump. Eurolube recommends that an air line lubricator be used with turbine oil (viscosity 150-170 SSU @
37°F) and set at a maximum oil feed rate of 1 drop every 2 hours of pump operatio n. The pump air motor has been coated internally with a
special synthetic grease at initial as sembly and does not require additional grease except during rea ssembly af ter a repair.
TO START PUMP:
Immer se the pump’s suctio n tube or fl uid inlet into the fl uid to be pu mped.1.
Connect the air coupler to the pump and turn the air regulator to the minimum s etting.2.
Direc t pump ou tlet hose into an approved waste oil c ontainer.3.
Slowly adjust th e air reg ulator until the p ump is pr imed and running smoothly. Be sure all air h as bee n purge d from th e 4.
system. T he pump s hould p rime in less tha n 30 sec onds.
Use the ai r regul ator to control th e pump’s spe ed and cycle rate. Always use the lowe st pres sure re quire d to obtain the 5.
desired flow rate. This will incre ase pump and se al life.
Never all ow a pump to be run dr y of the fluid being pumped. A dry pump quic kly speeds up, w hich co uld dam age the 6.
air motor and fluid seals. If the pum p sudde nly spe eds up, cut off th e air sup ply as so on as possibl e, refill the system
fluid res ervo ir and re prime t he pump.
If the pump will be un atten ded for a ny peri od of time, or to shut off the system at the end of a work shif t, always follow 7.
the Pres sure Re lief Pro cedure on page 5 of this manual.
If the pump will be un atten ded for a ny peri od of time, or to shut off the system at the end of a work shif t, always relieve 8.
the pump’s pressur e.
