AIR AND LUBE REQUIREMENTS
S
A 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.
S
If 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
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.
S
The 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.
S
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.
S
Secure the diaphragm pump legs to a suitable surface to insure
against damage by vibration.
MAINTENANCE
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 dirt and foreign matter during ser
vice disassembly and reassembly.
S
Keep good records of service activity and include pump in preven
tive maintenance program.
S
Service Kits are available to service two separate Diaphragm Pump
functions: 1. AIR SECTION, 2. FLUID SECTION. The Fluid Sec
tion is divided further to match typical active MATERIAL OPTIONS.

DUCKBILL CHECK VALVES (OPTIONAL)
Pump models with the suffix ( 0CX or 0DX) come equipped with duck
bill type checks. Standard duckbill pumps are shipped with the material
inlet in the top and the material outlet on the bottom manifold. To
change the direction of flow, disassemble the pump as instructed in the
FLUID SECTION and reassemble as described below. A pump that
was factory built with balls and seats can be retro fitted with duckbill
type check valves by purchasing the necessary parts and installing
them as shown.
Reassembly:
The duckbills may be installed in either direction to produce flow from
top to bottom of the pump or from bottom to top of the pump. In either
case, all of the (42) duckbills must point in the same direction.
Flow from Top to Bottom: (see page 5)
1. With (15) fluid caps installed, stand the pump upside down.
2. Place (21) insert into (42) duckbill and slide (41) sleeve over (42)
duckbill.
3. Slide the complete check assembly into the fluid cap bore with the
(21) insert end first. [Duckbills (42) point up.]
4. Position (19) O" ring over (41) sleeve.
5. Attach (35) manifold feet / (36) swivel assembly to the fluid caps.
6. Turn pump over to right side up position.
7. Assemble duckbill check as in Step #1.
8. Slide the complete check assembly into the fluid cap bore with the (41)
sleeve end first. [Duckbill is pointing down toward fluid cap cavity.]
9. Position (19) O" ring around (21) insert.
10. Attach (34) manifold / (36) swivel assembly to fluid cap.
Flow from Bottom to Top: (Inlet Bottom Outlet Top)
To reverse flow direction, slide check valve assemblies into the (15)
fluid caps backwards from what is indicated in Steps #2 and #7. In Step
#2, the (42) duckbills will be pointing down and in Step #7, they will be
pointing up.
