GENERAL DESCRIPTION

The 1" metallic diaphragm pump offers high volume delivery even at low

air pressures, easy self priming, the ability to pump various viscosity ma-

terials and the ability to pass solids (as stated in the chart above). The

pump is offered with optional wetted parts configurations to satisfy a va-

riety of application requirements. Refer to the "Model Description Chart".

AIR AND LUBE REQUIREMENTS

WARNING EXCESSIVE AIR PRESSURE. Can cause person-

al injury, pump damage or property damage. Do not exceed

maximum inlet air pressure as stated on pump.

A filter capable of filtering out particles larger than 50 microns should

be used on the air supply. There is no lubrication required 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 the "O"

rings and seals in the air motor section of the pump.

TRANSPORT AND STORAGE

Store in a dry place, do not remove product from box during storage.

Do not remove protection caps from inlet and outlet prior to installa-

tion.

Do not drop or damage box, handle with care.

INSTALLATION

Secure the diaphragm pump legs to a suitable surface to ensure

against damage by excessive vibration.

Pump cycle rate and operating pressure should be controlled by us-

ing an air regulator on the air supply.

The outlet material volume is governed not only by the air 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.

Use flexible connections (such as hose) at the suction and dis-

charge, these connections should not be rigid piped and must be

compatible with the material being pumped.

Install a ground wire where applicable.

OPERATING INSTRUCTIONS

NOTICE

Check the tightness of the (29) tie rod nuts after

first run in period due to possible compression set of the dia-

phragm. If retorquing is required, be sure all pressure has been re-

lieved from the pump and supply lines. Loosen (26) cap screws.

Retorque (29) flange nuts to 280 - 300 in. lbs (31.6 - 33.9 Nm). Tight-

en (26) cap screws to 120 - 140 in. lbs (13.6 - 15.8 Nm).

Always flush the pump with a solvent compatible with the 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 for a few

hours.

START-UP

1. Turn pressure control knob until motor starts to cycle.

2. Allow pump to cycle slowly until it is primed and all air is purged from

the fluid hose or dispensing valve.

3. Turn off dispensing valve and allow pump to stall - check all fittings

for leakage.

4. Adjust the regulator as required to obtain desired operating pres-

sure and flow.

SHUTDOWN

It is good practice to periodically flush entire pump system with a sol-

vent that is compatible with the material being pumped, especially if

the material being pumped is subject to "settling-out" when not in

use for a period of time.

Disconnect the air supply from the pump if it is to be inactive for a few

hours.

SERVICE

Certain ARO "Smart Parts" are indicated which should be available

for fast repair and reduction of down time.

Provide a clean work surface to protect sensitive internal moving

parts from contamination from dirt and foreign matter during service

disassembly and reassembly.

Keep good records of service activity and include pump in preven-

tive maintenance program.

USE ONLY GENUINE ARO REPLACEMENT PARTS TO ASSURE

PERFORMANCE AND PRESSURE RATING.

Contact your local authorized ARO Service Center for parts and

customer service information.

Service Kits are available to service two separate Diaphragm Pump

functions: 1. AIR SECTION, 2. FLUID SECTION. The Fluid Section

is divided further to match typical active MATERIAL OPTIONS.

FLUID SECTION SERVICE

GENERAL SERVICE NOTES:

Clean and inspect each part thoroughly upon disassembly, look for

deep scratches on metallic surfaces and nicks, cuts or flat spots on

"O" rings. Replace any of the parts that are of questionable condi-

tion.

Upon disassembly, look for any remnants of "O" rings in the air motor

valve areas.

Tools required: 3/16" Allen wrench, 3/8" Allen wrench, 4 mm Allen

wrench, 6 mm Allen wrench, 7/16" wrench / socket, 1/2" wrench, 3/4"

wrench / socket, 7/8" wrench / socket, 2-1/2" wrench, 13 mm wrench

/ socket, "O" ring pick, plastic mallet and spanner wrench.
