DESCRIPTION CHART
WARNING EXCESSIVE AIR PRESSURE. Can cause pump
damage, personal injury or property damage.
S A filter capable of filtering out particles larger than 50 microns
should be used on the air supply. In most applications there is no
lubrication required other than the "O"ring lubricant which is apĆ
plied during assembly or repair.
S The pump can be rotated 360_to suit the application. It may be
mounted upside down or on the wall with no effect on suction lift or
operating efficiency. The filter and regulator need to be oriented in
a normal vertical direction to function properly.
S Pipe plugs included for the material inlets, they can be switched to
accommodate piping requirements however the fluid inlet must alĆ
ways be in the port closest to the mounting base.
S When lubricated air is necessary, supply the air lubricator with a
good grade of SAE 90 wt. non-detergent oil and set the lubricator
to a rate not to exceed one drop per minute.
INSTALLATION
S NOTICE: Re-torque fasteners prior to use. Refer to page step
#22 on page 7 for information.
S Apply tape or pipe sealant to threads upon assembly to preĆ
vent leakage.
S Secure the diaphragm pump legs to a suitable surface to insure
against damage by vibration.
S To avoid problems install a particle fluid filter to screen out foreign
matter 1/32'' or larger in diameter.
S The pump is not recommended for submerged applications.
S When the diaphragm pump is used in a forced-feed (flooded inlet)
situation it is recommended that a ``CheckValve'' be installedat the
air inlet.
OPERATING INSTRUCTIONS
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 the air supply from the pump if it is to be inactive for a
few hours.
FLUID
S The outlet material volume is governed not only by the air supply
but also by the material supply available at the inlet. The materialĆ
supply tubing should not be too small or restrictive. Be sure not to
use hose which might collapse.
MAINTENANCE
Refer to the part list pg. 4 for Service Kit Information, parts view on
pg. 5. and Repair Proceedures on pgs 6 and 7.
S Certain ARO ``Smart Parts" are indicated which should be availĆ
able for fast repair and reduction of down time.
S Provide a clean work surface to protect sensitive internal moving
parts from contamination from dirt and foreign matter during serĆ
vice disassembly and reassembly.
S Keep good records of service activity and include pump in prevenĆ
tive maintenance program.
