GENERAL DESCRIPTION

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 / fluid sections.

Air operated double diaphragm pumps utilize a pressure differential in the air chambers to alternately create suction and positive fluid pressure in the fluid chambers, ball checks insure a positive flow of fluid.

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 pres- sure and will stop cycling once maximum line pressure is reached (dis- pensing device closed) and will resume pumping as needed.

AIR AND LUBE REQUIREMENTS

WARNING EXCESSIVE AIR PRESSURE. Can cause pump damage, personal injury or property damage.

SA 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.

SIf lubricated air is present, make sure that it is compatible with the Nitrile “O” rings in the air motor section of the pump.

OPERATING INSTRUCTIONS

SAlways 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.

SDisconnect the air supply from the pump if it is to be inactive for a few hours.

SThe 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.

SWhen the diaphragm pump is used in a forced-feed (flooded inlet) situation, it is recommended that a “Check Valve” be installed at the

air inlet.

SSecure the diaphragm pump legs to a suitable surface to insure against damage by vibration.

MAINTENANCE

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

SCertain ARO “Smart Parts” are indicated which should be available

for fast repair and reduction of down time.

SService kits are divided to service two separate diaphragm pump functions: 1. AIR SECTION, 2. FLUID SECTION. The FLUID SEC-

TION is divided further to match typical part MATERIAL OPTIONS.

SProvide a clean work surface to protect sensitive internal moving parts from contamination from dirt and foreign matter during service

disassembly and reassembly.

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

tive maintenance program.

SBefore disassembling, empty captured material in the outlet man- ifold by turning the pump upside down to drain material from the pump.

FLUID SECTION DISASSEMBLY

1.Remove top manifold(s).

2.Remove (22) balls, (19) “O” rings, (21) seats.

3.Remove (15) fluid caps.

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

4.Remove the (6) nut, (7) or (7 / 8) diaphragms and (5) washers.

5.Remove (3) “O” rings.

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

FLUID SECTION REASSEMBLY

SReassemble in reverse order.

SClean and inspect all parts. Replace worn or damaged parts with

new parts as required.

SLubricate (1) diaphragm rod and (2) “O” ring with Key-LubeRgrease. S Use ARO pn / 98931-T bullet (installation tool) to aid in installation of

(2) “O” ring on (1) diaphragm rod.

SBe certain (7) or (7 / 8) diaphragm(s) align properly with (15) fluid caps before making final torque adjustments on bolt and nuts to

avoid twisting the diaphragm.

SFor models with PTFE diaphragms: Item (8) Santoprene diaphragm is installed with the side marked “AIR SIDE” towards the pump cen-

ter body. Install the PTFE diaphragm with the side marked “FLUID SIDE” towards the fluid cap.

SRe-check torque settings after pump has been re-started and run a while.
