OPERATING AND SAFETY PRECAUTIONS

READ, UNDERSTAND AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.

EXCESSIVE AIR PRESSURE
STATIC SPARK

WARNING

injury, pump damage or property damage.
Do not exceed the maximum inlet air pressure as stated on

y

the pump model plate.
Be sure material hoses and other components are able to

y

withstand  uid pressures developed by this pump. Check
all hoses for damage or wear. Be certain dispensing device
is clean and in proper working condition.

WARNING

severe injury or death. Ground pump and pumping system.
Use the pump grounding screw terminal provided. Use ARO®

y

part no. 66885-1 ground kit or connect a suitable ground wire
(12 ga. min.) to a good earth ground source.
Secure pump, connections and all contact points to avoid

y

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

y

ci c grounding requirements.
After grounding, periodically verify continuity of electrical

y

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 device

y

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

y

Use proper ventilation.

y

Keep inflammables away from heat, open flames and

y

sparks.
Keep containers closed when not in use.

y

WARNING

cause severe injury. Pipe exhaust away from work area and
personnel.
In the event of a diaphragm rupture, material can be forced

y

out of the air exhaust mu er.
Pipe the exhaust to a safe remote location when pumping

y

hazardous or in ammable materials.
Use a grounded 1” minimum i.d. hose between the pump

y

and the mu er.

WARNING

injury or property damage. Do not service or clean pump,
hoses or dispensing valve while the system is pressurized.
Disconnect air supply line and relieve pressure from the

y

system by opening dispensing valve or device and / or
carefully and slowly loosening and removing outlet hose or
piping from pump.

WARNING

jury or property damage. Do not attempt to return a pump
to the factory or service center that contains hazardous
material. Safe handling practices must comply with local
and national laws and safety code requirements.

GENERAL DESCRIPTION

PARTS AND SERVICE KITS

The ARO diaphragm pump o ers high volume delivery even at low
air pressure and a broad range of material compatibility options are
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 di eren­tial in the air chambers to alternately create suction and a positive
 uid pressure in the  uid chambers, valve checks insure a positive
 ow of  uid.
Pump cycling will begin as air pressure is applied and 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

age, personal injury or property damage.

A  lter capable of  ltering out particles larger than 50 microns

y

should be used on the air supply. There is no lubrication re-

quired other than the “O” ring lubricant which is applied during

assembly or repair.

If lubricated air is present, make sure that it is compatible with

y

the “O” rings and seals in the air motor section of the pump.

EXCESSIVE AIR PRESSURE. Can cause pump dam-

OPERATING INSTRUCTIONS

Always  ush the pump with a solvent compatible with the ma-

y

terial 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 sup-

y

ply, 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 in-

stalled at the air inlet.

Secure the diaphragm pump legs to a suitable surface to insure

y

against damage by vibration.

Refer to the part views and descriptions as provided on pages 4
through 7 for parts identi cation and service kit information.

Certain ARO “Smart Parts” are indicated which should be avail-

y

able for fast repair and reduction of down time.
Service kits are divided to service two separate diaphragm

y

pump functions: 1. AIR SECTION, 2. FLUID SECTION. The Fluid
Section is divided further to match typical part Material Op­tions.

MAINTENANCE

Provide a clean work surface to protect sensitive internal mov-

y

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

y

preventive maintenance program.
Before disassembling, empty captured material in the outlet

y

manifold by turning the pump upside down to drain material
from the pump.

FLUID SECTION DISASSEMBLY

Remove (61) outlet manifold and (60) inlet manifold.

1.
Remove (22) balls, (19) “O” rings (if applicable) and (21) seats.

2.
Remove (15)  uid caps.

3.

NOTE: Only PTFE diaphragm models use a primary diaphragm (7)
and a backup diaphragm (8). Refer to the auxiliary view in the Fluid
Section illustration.

4. Remove the (6) diaphragm washer, (7) or 7 / 8) diaphragms and
(5) backup washer.

NOTE: Do not scratch or mar the surface of (1) diaphragm rod.

FLUID SECTION REASSEMBLY

SERVICE NOTE: ARO pn 204214-T diaphragm assembly tool is rec­ommended for use when reassembling the pump.

Reassemble in reverse order. Refer to the torque requirements

y

on page 5.
Clean and inspect all parts. Replace worn or damaged parts

y

with new parts as required.
Lubricate (1) diaphragm rod and (144) “U” cups with Lubriplate®

y

FML-2 grease (94276 grease packet is included in service kit).
For models with PTFE diaphragms: Item (8) Santoprene dia-

y

phragm is installed with the side marked “AIR SIDE” towards the
pump center body. Install the (7) PTFE diaphragm with the side
marked “FLUID SIDE” towards the (15)  uid cap.
Re-check torque settings after the pump has been re-started

y

and run a while.
