GENERAL DESCRIPTION
MAINTENANCE
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.
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

TROUBLE SHOOTING
Check for kinked (restrictive) outlet material hose.
y
Check for kinked (restrictive) or collapsed inlet material hose.
y
Check for pump cavitation - suction pipe should be sized at
y
least as large as the inlet thread diameter of the pump for
proper ow if high viscosity uids are being pumped. Suction
hose must be a non-collapsing type, capable of pulling a high
volume.
Check all joints on the inlet manifolds and suction connections.
y
These must be air tight.
Inspect the pump for solid objects lodged in the diaphragm
y
chamber or the seat area.
