Grounding

The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.

Pump: Use a ground wire and clamp as shown in FIG.

1.

Fluid hoses: Use only electrically conductive hoses.

Air compressor: Follow manufacturer’s recommenda-

tions.

Fluid supply container: Follow the local code.

To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray

gun/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.

To ground the pump: remove the ground screw (Z)
and insert through the eye of the ring terminal at end of
the ground wire (Y). Fasten the ground screw back onto
the pump and tighten securely. Connect the other end of
the ground wire to a true earth ground. See Fig. To
order a ground wire clamp, order Part. No. 222011.

Installation

Mounting

Mount the pump securely so that it cannot move
around during operation. Failure to do so could result
in personal injury or equipment damage.

1. Plan the mounting layout for easy operator access
to the pump air controls, sufficient room to change
drums and a secure mounting platform.

2. If using a follow plate (H), remove the drum cover.
Scoop the material to the center of the drum. Place
the plate on the material. Guide the pump foot valve
through the plate.

3. Mount the pump to the drum cover or other suitable
mounting device.

4. For ease in changing drums, install a pump eleva­tor.

Air and Fluid Line Accessories

Refer to FIG. 2 for the following instructions.

• The ground wire (B) reduces the risk of static
sparking.

NOTICE

Do not hand the air accessories directly on the air
inlet. The fittings are not strong enough to support the
accessories and may cause one or more to break.
Provides a bracket on which to mount the accesso­ries.

NOTE: Install the air line accessories in the order shown
in Fig.

1. Install a pump runaway valve (G) to shut off the air
to the pump if the pump accelerates beyond the
pre-adjusted setting. A pump that runs too fast can
be seriously damaged.

2. Install an air line lubricator (F) for automatic air
motor lubrication.

3. Install a bleed-type master air valve (J) to relieve air
trapped between the valve and the motor.

4. Install the air regulator (C) to control pump speed
and pressure.

5. Install an air line filter (E) to remove harmful dirt and
contaminants from the compressed air supply.

Three accessories are required in your system: an air
shut-off valve/air bleed device, fluid drain valve, and
ground wire. These accessories help reduce the risk of
serious bodily injury, including fluid injection, splashing
in the yes or on the skin, injury from moving parts if
you are adjusting or repair the pump, and explosion
from static sparking.

• The air bleed device relieves air trapped between it
and air motor after the air supply is shut off.
Trapped air can cause the motor to cycle
unexpectedly, causing serious injury if you are
adjusting or repairing the pump. Use a bleed-type
master air valve (J). Install them near the pump air
inlet within easy reach from the pump.

• The fluid drain (K) assists in relieve fluid pressure
in the displacement pump, hoses, and dispensing
valve. Triggering the valve to relieve pressure may
not be sufficient.

6. Install a second bleed-type master air valve (J)
upstream from all other accessories, to isolate the
accessories for servicing.

Operation

Operation

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever
you see this symbol.

This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury
from pressurized fluid, such as skin injection,
splashing fluid and moving parts, follow the Pressure
Relief Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.

1. Close the pump air regulator and bleed-type master
air valve (required in the system).

2. Hold a metal part of the dispensing valve firmly to a
grounded metal waste container and trigger the
valve to relieve the fluid pressure.

Start Up

1. If there are multiple pumps on the air line, close the
air regulators and bleed-type master air valves to all
but one pump. If there is only one pump, close its air
regulator and bleed-type master air valve.

2. Open the master air valve from the compressor.

NOTICE

The pump has a rated ratio of 50:1. However, it is
capable of reaching stall pressures equal to 60
times the air input pressure. Calculate the fluid
output pressure using the air regulator reading.
Multiply the air pressure shown on the regulator
gauge by 60. For example:

140 psi air x 60 = 8400 psi fluid output

0.97 MPa air x 60 = 58.2 MPa fluid output

9.7 bar air x 60 = 582 bar fluid output

Regulate air to the pump so that no air line or fluid
line component or accessory is over pressurized.

6. Never allow the pump to run dry of the material
being pumped.

NOTICE

A dry pump will quickly accelerate to a high speed,
possibly damaging itself. If your pump accelerates
quickly, or is running too fast, stop it immediately and
check the material supply. If the supply container is
empty and air has been pumped into the lines, prime
the pump and lines with material, or flush it and leave
it filled with a compatible solvent. Be sure to eliminate
all air from the material lines.

3. Open the dispensing valve into the grounded metal
waste container, making firm metal-to-metal contact
between the container and valve. Open the
bleed-type master air valve and open the pump air
regulator slowly, just until the pump is running.
When the pump is primed and all air has been
pushed out of the lines, close the dispense valve.

4. If there is more than one pump, repeat this proce­dure for each pump.

NOTE: When the pump is, and with sufficient air sup­plied, the pump starts when the dispensing valve is
opened and shuts off when closed.

5. Set the air pressure to each pump at the lowest
pressure needed to get the desired results.

308883S 5

NOTE: A pump runaway valve (G) can be installed on
the air line to automatically shut off the pump if it starts
to run too fast.

7. Read and follow the instructions supplied with each
components in the system.

8. To shut off the system always follow the Pressure
Relief Procedure.
