GENERAL DESCRIPTION
The ARO Di phr gm Pump offers high volume delivery even t low ir
pressure nd bro d r nge of m teri l comp tibility options v il ble.
Refer to the model nd option ch rt. ARO pumps fe ture st ll resist nt
design, modul r ir motor / fluid sections.
Air oper ted double di phr gm pumps utilize pressure differenti l in
the ir ch mbers to ltern tely cre te suction nd positive fluid pressure in
the fluid ch mbers, b ll checks insure positive flow of fluid.
Pump cycling will begin s ir pressure is pplied nd it will continue to
pump nd keep up with the dem nd. It will build nd m int in line presĆ
sure nd will stop cycling once m ximum line pressure is re ched (disĆ
pensing device closed) nd will resume pumping s needed.

OPERATING AND SAFETY PRECAUTIONS
READ, UNDERSTAND, AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
EXCESSIVE AIR PRESSURE
STATIC SPARK
HAZARDOUS MATERIALS
HAZARDOUS PRESSURE
WARNING EXCESSIVE AIR PRESSURE. Can ause personĆ
al injury, pump damage or property damage.
SDo not ex eed the maximum inlet air pressure as stated on the
pump model plate.
SBe sure material hoses and other omponents are able to withĆ
stand fluid pressures developed by this pump. Che k all
hoses for damage or wear. Be ertain dispensing devi e is
lean and in proper working ondition.
WARNING STATIC SPARK. Can ause explosion resulting
in severe injury or death. Ground pump and pumping system.
SUse the pump grounding s rew terminal provided. Use Aro
Part No. 66885Ć1 Ground Kit or onne t a suitable ground wire
(12 ga. min.) to a good earth ground sour e.
SSe ure pump, onne tions and all onta t points to avoid
vibration and generation of onta t or stati spark.
SConsult lo al building odes and ele tri al odes for spe ifi
grounding requirements.
SAfter grounding, periodi ally verify ontinuity of ele tri al
path to ground. Test with an ohmmeter from ea h omponent
(e.g., hoses, pump, lamps, ontainer, spray gun, et .) to
ground to insure ontinuity. Ohmmeter should show 100
ohms or less.
SSubmerse the outlet hose end, dispensing valve or devi e in
the material being dispensed if possible. (Avoid free streamĆ
ing of material being dispensed.)
SUse hoses in orporating a stati wire.
SUse proper ventilation.
SKeep inflammables away from heat, open flames and sparks.
SKeep ontainers losed when not in use.
WARNING Pump exhaust may ontain ontaminants. Can
ause severe injury. Pipe exhaust away from work area and
personnel.
SIn the event of a diaphragm rupture material an be for ed out
of the air exhaust muffler.
SPipe the exhaust to a safe remote lo ation when pumping hazĆ
ardous or inflammable materials.
SUse a grounded 1" min. i.d. hose between the pump and the
muffler.
WARNING HAZARDOUS PRESSURE. Can result in serious
injury or property damage. Do not servi e or lean pump,
hoses or dispensing valve while the system is pressurized.
SDis onne t air supply line and relieve pressure from the sysĆ
tem by opening dispensing valve or devi e and / or arefully
and slowly loosening and removing outlet hose or piping from
pump.
WARNING HAZARDOUS MATERIALS. Can ause serious
injury or property damage. Do not attempt to return a pump to
the fa tory or servi e enter that ontains hazardous material.
Safe handling pra ti es must omply with lo al and national
laws and safety ode requirements.
SObtain Material Safety Data Sheets on all materials from the
supplier for proper handling instru tions.
WARNING EXPLOSION HAZARD. Models ontaining aluĆ
minum wetted parts annot be used with III.ĆTri hloroethane,
Methylene Chloride or other Halogenated Hydro arbon solĆ
vents whi h may rea t and explode.
SChe k pump motor se tion, fluid aps, manifolds and all
wetted parts to assure ompatibility before using with solĆ
vents of this type.
WARNING MISAPPLICATION HAZARD. Do not use models
ontaining aluminum wetted parts with food produ ts for huĆ
man onsumption. Plated parts an ontain tra e amounts of
lead.
CAUTION Verify the hemi al ompatibility of the pump
wetted parts and the substan e being pumped, flushed or reĆ
ir ulated. Chemi al ompatibility may hange with temperaĆ
ture and on entration of the hemi al(s) within the
substan es being pumped, flushed or ir ulated. For spe ifi
fluid ompatibility, onsult the hemi al manufa turer.
CAUTION Maximum temperatures are based on me haniĆ
al stress only. Certain hemi als will signifi antly redu e
maximum safe operating temperature. Consult the hemi al
manufa turer for hemi al ompatibility and temperature limĆ
its. Refer to PUMP DATA on page 1 of this manual.
CAUTION Be ertain all operators of this equipment have
been trained for safe working pra ti es, understand it's limitaĆ
tions, and wear safety goggles / equipment when required.
CAUTION Do not use the pump for the stru tural support of
the piping system. Be ertain the system omponents are
properly supported to prevent stress on the pump parts.
SSu tion and dis harge onne tions should be flexible onĆ
ne tions (su h as hose), not rigid piped, and should be omĆ
patible with the substan e being pumped.
CAUTION Prevent unne essary damage to the pump. Do
not allow pump to operate when out of material for long periĆ
ods of time.
SDis onne t air line from pump when system sits idle for long
periods of time.
CAUTION Use only genuine ARO repla ement parts to asĆ
sure ompatible pressure rating and longest servi e life.
