y

grounded when it is pumping,  ushing, recirculating or
spraying  ammable materials such as paints, solvents,
lacquers, etc. or used in a location where surrounding
atmosphere is conducive to spontaneous combustion.
Ground the dispensing valve or device, containers, hos­es and any object to which material is being pumped.
Secure pump, connections and all contact points to

y

avoid vibration and generation of contact or static spark.
Consult local building codes and electrical codes for

y

speci c grounding requirements.
After grounding, periodically verify continuity of

y

electrical path to ground. Test with an ohmmeter
from each component (e.g., hoses, pump, clamps, con­tainer, spray gun, etc.) to ground to insure continuity.
Ohmmeter should show 0.1 ohms or less.
Submerse the outlet hose end, dispensing valve or

y

device in the material being dispensed if possible.
(Avoid free streaming of material being dispensed.)
Use hoses incorporating a static wire.

Check pump motor section,  uid caps, manifolds and

y

all wetted parts to assure compatibility before using
with solvents of this type.

CAUTION

Verify the chemical compatibility of the
pump wetted parts and the substance being pumped,
flushed or recirculated. Chemical compatibility may
change with temperature and concentration of the
chemical(s) within the substances being pumped,
 ushed or circulated. For speci c  uid compatibility,
consult the chemical manufacturer.

CAUTION

GENERAL DESCRIPTION

MAINTENANCE

The ARO diaphragm pump offers high volume delivery even
at low air pressure and a broad range of material compatibility
options available. Refer to the model and option chart. ARO
pumps feature stall resistant design, modular air motor /  uid
sections.
Air operated double diaphragm pumps utilize a pressure dif­ferential in the air chambers to alternately create suction and
positive  uid pressure in the  uid chambers, ball checks insure
a positive  ow of  uid.
Pump cycling will begin as air pressure is applied and it will
continue to pump and keep up with the demand. It will build
and maintain line pressure and will stop cycling once maxi­mum line pressure is reached (dispensing device closed) and
will resume pumping as needed.

AIR AND LUBE REQUIREMENTS

WARNING

applied during assembly or repair.
When lubricated air is necessary, supply the air lubricator

y

with a good grade of SAE 90 wt. non-detergent oil and
set the lubricator to a rate not to exceed one drop per
minute.

OPERATING INSTRUCTIONS

Always  ush the pump with a solvent compatible with the

y

material being pumped if the material being pumped is
subject to setting up” when not in use for a period of time.
Disconnect the air supply from the pump if it is to be inactive

y

for a few hours.
The outlet material volume is governed not only by the air

y

supply but also by the material supply available at the inlet.
The material supply tubing should not be too small or restric­tive. Be sure not to use hose which might collapse.
When the diaphragm pump is used in a forced-feed ( ooded

y

inlet) situation, it is recommended that a “Check Valve” be
installed at the air inlet.
Secure the diaphragm pump legs to a suitable surface to in-

y

sure against damage by vibration.

Refer to the part views and descriptions as provided on page 4
through 7 for parts identi cation and Service Kit information.

Certain ARO “Smart Parts” are indicated which should be

y

available for fast repair and reduction of down time.
Service kits are divided to service two separate dia-

y

phragm pump functions: 1. AIR SECTION, 2. FLUID SEC­TION. The FLUID SECTION is divided further to match
typical part MATERIAL OPTIONS.
Provide a clean work surface to protect sensitive internal

y

moving parts from contamination from dirt and foreign
matter during service disassembly and reassembly.
Keep good records of service activity and include pump

y

in preventive maintenance program.
