309028ZAT 9
Uncrating the System
The Uni-Drum Supply System was carefully packaged
for shipment by Graco. When the system arrives,
perform the following procedure to uncrate the system.
To uncrate the system, perform the following steps:
1. Inspect the crate carefully for shipping damage.
Contact the carrier promptly if damage is
discovered.
2. Remove the plywood sides and top of the crate.
3. Inspect the contents carefully. There should not be
any loose or damaged parts.
4. Compare the packing slip against all items included
in the crate. Report any shortages or other
inspection problems immediately.
5. Remove the band straps that hold the Uni-Drum to
the pallet.
6. The Uni-Drum is ready for installation. Before
installing the system, read the General Description
section on page 18 to become familiar with the
system components.
Overview
Installation Overview
The location of the Uni-Drum should allow for easy
loading and unloading of the 300 gallon (1200 liter)
magnadrum or other tote drums with either a forklift
truck or pallet-jack hand truck.
The Uni-Drum Supply System must be leveled and
mounted on a horizontal floor. An unleveled condition
can keep the Uni-Drum from operating properly.
Anchor the frame’s four foot pads securely to the floor.
The anchor bolts should be sized with sufficient safety
factor to withstand the downward force of the follower
plate and other objects that can push the frame off the
floor.
Operation Overview
The Uni-Drum is a supply system that evacuates fluids
from a 300 gallon (1200 liter) magnadrum or other tote
drums.
Each Uni-Drum includes two Graco air motors and
displacement pumps, a ram assembly with a follower
plate, a pneumatic layout panel that controls the air
components and a junction box panel that connects with
an electrical controller (supplied by the customer).
In short, the operator places the magnadrum inside the
frame with the follower plate placed directly on top of the
material. Locally, the system can be operated using the
pneumatic layout panel. Remotely, the system can be
operated using signals through the junction box panel.
Two displacement pumps evacuate material out of each
magnadrum. After removing the empty drum from the
system, the operator repeats the evacuation process
when another drum is ready for evacuation.
NOTICE
Moving the unit off of the pallet without following the
uncrating procedure can damage the equipment.

General Description
A general description of the Uni-Drum Supply System
helps the installers and operators become familiar with
the system components. Contact your Graco distributor
for help in choosing accessories to suit your particular
needs.
Before you install the system, you should be familiar
with the parts described in the following paragraphs.
System Components
See F IG . 1 on page 10.
•Uni-Drum Supply Unit (A,B) is usually setup to
alternate the material supply operation between the
left hand (LH) and right hand (RH) Supply Units,
which is accomplished using a combination of
robotic software programming (provided by others)
and manual operators. Drum changeovers occur
after the Follower Plate (D) has reached its preset
low limit level in the drum. Alternating between
Supply Units eliminates the downtime that is usually
expended unloading an empty drum and reloading a
full drum.
- LH Supply Unit (A) accommodates one 300
gallon (1200 liter) drum. The LH Supply Unit
has a local Pneumatic Logic Panel (G) and
Junction Box Panel (H).
- RH Supply Unit (B) accommodates one 300
gallon (1200 liter) drum. The RH Supply Unit
has a local Pneumatic Logic Panel (G) and
Junction Box Panel (H).
• The two Dura-Flo™ 1800 Pumps (C) have XL
10000™ air motors. The Pumps evacuate material
from the drum.
•The Follower Plate (D) is connected to the ram
assembly and is designed to apply an even amount
of pressure to the material in the drum. With the
Follower Plate in its raised position, the operator
moves a drum inside the frame. The Follower Plate
is lowered directly on top of the material in the drum.
When pressure is applied to the Follower Plate, the
material is pumped out of the drum through hoses,
which are attached to the Pump outlet ports. When
the drum is empty, the operator raises the Follower
Plate, removes the empty drum. The process is
repeated when another drum is ready to be
unloaded.
•Pneumatic Panel Air Filter (F) filters air to the
Pneumatic Logic Panel (G). The 5 micron filter
removes particles, such as dust, moisture, foreign
matter and other contaminants from the
compressed air.
•TheSafety Pins (M) are used to keep the ram from
lowering while in the fully raised position during
drum changes or maintenance of the supply
system.
•Main Air Shutoff Valve (P) is used to open or
shutoff the air supply to the entire Supply Unit (A,B).
Pneumatic Logic Panel (G)
See F IG . 4 on page 13 and F IG . 5 on page 14.
The Pneumatic Logic Panel (G) includes the following
system components. For more information, refer to the
Pneumatic Diagram on page 92.
• PUMP NO. 1 REGULATOR Control Knob (AC)
controls Pump speed and outlet pressure for Pump
No. 1 by adjusting the air pressure to the Pump.
• PUMP NO. 1 PRESSURE Air Gauge (AA) displays
the amount of air pressure supplied to Pump No. 1.
• PUMP NO. 2 REGULATOR Control Knob (AE)
controls Pump speed and outlet pressure for Pump
No. 2 by adjusting the air pressure to the Pump.
• PUMP NO. 2 PRESSURE Air Gauge (AB) displays
the amount of air pressure supplied to Pump No. 2.
• FOLLOWER VENT Directional Valve (AD) is
activated to open the vent to relieve container
pressure.
• RAM UP Pushbutton (AF) turns on air pressure to
raise the Follower Plate (D) when used in
conjunction with the RAM POSITION Switch (AG).
• The RAM POSITION Switch (AG) performs the
following three functions:
- Place the switch in the RAISE position to raise
the Follower Plate (D).
- Place the switch in the HOLD/NEUTRAL
position to hold the Follower Plate (D) in the
current position.
- Place the switch in the LOWER position to
lower the Follower Plate (D).

Junction Box Panel (H)
See F IG . 6 on page 16.
The Junction Box Panel (H) includes the following
system components. For additional information, refer to
the Electrical Diagram on page 91.
• SYSTEM PRESSURIZED Light is lit when air
pressure is supplied to the system; the light is
extinguished when the air supply is depressurized.
This occurs after the PUMP ON Pushbutton has
been pushed and the Pumps turned on.
• PUMP ACTIVE Light is lit when the air supply is
turned on to the Pumps; the light is extinguished
when the Pumps are inactive, thus turned off. This
is activated by the PUMP ON Pushbutton.
• AIR PRESS ON Light is lit when air pressure to the
system is turned on; the light is extinguished when
air pressure to the system is shutoff.
• RAM READY Light is lit when the drum is in
position; the light is extinguished when the drum is
not in position.
• PUMP READY Light is lit when the Pumps are
primed and ready for operation; the light is
extinguished when the Pumps are not ready for
operation.
• PRIME PUMP Pushbutton turns on the Pumps, for
priming. When the Pumps are primed, the PUMP
READY Light turns on. The switch is not used when
the PUMP READY Light is lit. The PUMP ACTIVE
Light will blink.
• PUMP RESET Pushbutton resets the Pumps to an
active state. When the Pumps are reset, the PUMP
ACTIVE Light turns off. The switch is not used when
the PUMP ACTIVE Light is lit. The PUMP READY
Light is on.
• PUMP ON Pushbutton turns the Pumps on and off.
When the Pumps are turned on, the PUMP ACTIVE
Light also turns on. When the Pumps are turned off,
the PUMP ACTIVE Light also turns off.
• BULK SUPPLY DEPRESSURIZATION Pushbutton
opens the depressurization valve to lower the fluid
pressure.
• LOCAL REMOTE Switch puts the system into or out
of automatic operation.
