GENERAL DESCRIPTION
The 1” metallic diaphragmpumpoffers high volume deliveryevenat low
air pressures,easy self priming, the abilityto pumpvarious viscosityma-
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-
rietyofapplicationrequirements.Refer tothe “ModelDescription 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.
S A filter capableoffiltering outparticles largerthan 50 micronsshould
be used ontheair supply. There is no lubrication required other than
the “O” ring lubricant which is applied during assembly or repair.
S If lubricatedairis present,make sure thatit iscompatible withthe “O”
rings and seals in the air motor section of the pump.
TRANSPORT AND STORAGE
S Store inadry place, donot remove productfrombox during storage.
S Do not remove protection caps from inlet and outlet prior to installa-
tion.
S Do not drop or damage box, handle with care.
INSTALLATION
S Secure the diaphragm pump legs to a suitable surface to insure
against damage by excessive vibration.
S Pump cycle rate and operating pressureshould be controlled by us-
ing an air regulator on the air supply.
S The outlet materialvolume is governed notonly by the airsupply but
also bythematerial supply availableat the inlet.The material supply
tubing should not be too small or restrictive. Be sure not to use hose
which might collapse.
S 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.
S Install a ground wire where applicable.
OPERATING INSTRUCTIONS
NOTICE
Check the t ightness 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) flangenuts to 280-300 in. lbs (31.6 -33.9Nm). Tight-
en (26) cap screws to 120 - 140 in. lbs (13.6 - 15.8 Nm).
S 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.
S Disconnect theair supply from the pumpif it is to beinactive for afew
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
S It isgood practice toperiodically flushentirepump systemwith 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.
S Disconnect theair supply from the pumpif it is to beinactive for afew
hours.
SER VICE
S
Certain ARO “Smart Parts” are indicated which should be available
for fast repair and reduction of down time.
S Provide a clean work surface to protect sensitive internal moving
parts from contamination from dirtandforeign matter during service
disassembly and reassembly.
S Keep good records of service activity and include pump in preven-
tive maintenance program.
S USE ONLY GENUINE ARO REPLACEMENT PARTS TO ASSURE
PERFORMANCE AND PRESSURE RATING.
S Contact your local authorized ARO Service Center for parts and
customer service information.
S 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:
S 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.
S Upon disassembly, lookfor anyremnants of“O” ringsin theair motor
valve areas.
