Pipe exhaust away to a safe location. Use a suitable diam-
eter grounded hose between pump and muffler. Refer to
table for proper size.
Pump Series
1”
Hose Size
(min ID)
3/8”
y
Install a ground wire where applicable.
y
Verify correct model / configuration prior to installation.
y
Pumps are tested in water at assembly. Flush pump with
compatible fluid prior to installation.
y
When 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.
y
Flooded suction inlet pressure must not exceed 10 psig
(0.69 bar).
y
Always flush the pump with a solvent compatible with
the material being pumped if the material being pumped
will solidify when not in use for a period of time.
OPERATING INSTRUCTIONS
y
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.
y
Disconnect the air supply from the pump if it is to be in-
active for a few hours.
y
The outlet material volume is governed not only by the air
supply, but also by the material supply available at the in-
let. The material supply tubing should not be too small or
restrictive. Be sure not to use hose which might collapse.
y
When 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.
y
Secure the diaphragm pump legs to a suitable surface to
insure against damage by vibration.
MAINTENANCE
y
Certain ARO “Smart Parts” are indicated which should be
available for fast repair and reduction of down time.
y
Provide a clean work surface to protect sensitive internal
moving parts from contamination from dirt and foreign
matter during service disassembly and reassembly.
y
Keep good records of service activity and include the
pump in preventive maintenance program.
y
Service kits are available to service two separate dia-
phragm pump functions: 1. AIR SECTION 2. FLUID SEC-
TION. The Fluid Section is divided further to match typical
part Material Options.
y
Before disassembling, empty captured material in the
outlet manifold by turning the pump upside down to
drain material from the pump.
