GENERAL DESCRIPTION

The ARO model WP0409C8XXXXXXXX wash pump has been

designed for heavy duty cleaning with detergents, caustics, and

dilute acid type deaners. The 9:1 ratio double acting pump section

is separated from the air motor to prevent any cleaning solution

from coming in contact with and damaging the air motor.

All metal parts in the pumping section are manufactured from 316

stainless steel or "K' monel, the packing and "0" rings are manufac-

tured from Nitrile, and the packing back-ups and portions of the

material piston are manufactured from acetal resins.

Packings, "0" rings, and material pistons of virgin PTFE and packing

back-ups of glass fi lled tefl on are available on special request. The

4-1/4 inch air motor is of the double acting reciprocating type.

The valving in the air motor uses "D" type valves and is mechanical

with a pneumatic assist. The WP0409C8XXXXXXXX wash pump

may be directly mounted in the two inch bung of a standard 55

gal. drum or, when using the 61113 mounting bracket, the pump

can be mounted on the wall or in a 55 gal. open head drum.

OPERATING INSTRUCTIONS

Oil the lower pump assembly section by squirting SAE 90

Gear Oil into the two holes marked "Oil Daily".

Fill the cleaning solution container with clear water.

Connect the air supply line to the air line lubricator.

Open the (6) control handle assembly by squeezing the trig-

ger until water sprays out the spray tip.

Adjust air line oiler to approximately 1 drop every 2 minutes

by turning adjusting screw clockwise for less fl ow.

Close control handle.

Add the proper amount of cleaning solution to cleaning

solution container. Insert the (3) bent pipe assembly into the

cleaning solution and open the control handle assembly.

Continue holding the control handle open until spray from

the (3) bent pipe assembly has thoroughly mixed the clean-

ing solution.

NOTE:

Most cleaning solutions will perform more effi ciently in warm

water.

Powdered detergents will be easier to mix if they are dissolved

in a container of hot water fi rst.

Consult chemical manufacturer's recommendations for proper

mixing and concentration

The air supply line should be disconnected when the wash

pump assembly is not in operation.

CAUTION: Do not allow the air motor to run after the

solution container is emptied.

CLEANING INSTRUCTIONS

Use the cleaning instructions supplied by the cleaning chemical

supplier. General cleaning instructions for detergents and caustics:

(In the event cleaning instructions are not supplied by chemical

supplier).

Lightly and rapidly cleaning solution to object being cleaned.

Let cleaning solution stand on the object for two or three

minutes.

Starting from the bottom up, clean the object with cleaning

solution holding the spray tip 6 to 8 inches away from object

and at approximately 45°. The 45° angle will produce a chisel-

ing eff ect for better cleaning.

Rinse the object thoroughly with clean water from the top

down.

General cleaning instructions for aluminum brightening: (If not

supplied by chemical supplier).

Apply aluminum brightener to an area of approximately 100

square feet (approximately 3 semi-trailer panels) from the

bottom up.

Let the brightening solution soak until light foaming occurs

on the aluminum.

Rinse thoroughly with clear clean water from the top down.

CAUTION: Brightening solution will etch glass and will

burn aluminum if permitted to soak after the light

foaming occurs.

MAINTENANCE

The basic pump consists of two major components: 1. Air Motor,

2. Lower Pump End. The air motor is connected to the lower pump

end by a spacer tube - this allows access for lubricating the upper

packing gland in the lower pump end, and to prevent air motor

contamination because of normal wear and eventual leakage

through material packing gland. The air motor is removable and is

to be serviced separately. Refer to air motor manual for service and

parts.

Periodically fl ush entire pump system with a solvent that is

compatible with the material being pump.

Periodically inspect and replace if necessary the (13) screen

assembly on the bottom of the (4) suction tube assembly.

Disassembly should be done on a clean work bench with clean

cloths to keep parts clean.

If replacement parts are necessary, consult drawing containing

parts for identifi cation.

Before assembling, lubricate parts where required. When as-

sembling "O" rings or parts adjacent to "O" rings, care must be

exercised to prevent damage to "O" rings and "O" ring groove

surfaces.
