Unpacking 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.

WARNING

EQUIPMENT MOVING HAZARD

Removing the unit off the pallet without following the uncrating procedure will damage the equipment.

To unpack the system, do the following:

1. Inspect carefully for shipping damage. Contact the carrier promptly if damage is discovered.

2. Carefully unwrap and remove the plastic packaging material.

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.

NOTE: The Uni-Drum is ready for installation. Before installing the system, read the “General Description” section to become familiar with the system components.

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 a forklift.

Overview

Operation Overview

The Uni-Drum is a supply system that evacuates fluids from a 300 gallon (1200 liter) magnadrum or other tote drums.

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.

Each Uni-Drum includes two Graco air motors and displacement pumps, a ram assembly with a follower plate and a pneumatic layout panel that controls the air components.

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 pneumatic layout panel.

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.

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.

System Components

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.

Fig. 1 shows the typical Uni-Drum supply system equipped with Premier t air motors. The following list identifies the Uni-Drum system components:

D

Uni-Drum System (A) 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 pneumatic logic and manual operators. Drum changeovers occur after the follower plate 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 pump supply unit (A) accommodates one

300 gallon (1200 liter) drum. The LH supply unit has a local pneumatic layout panel.

-RH pump supply unit (B) accommodates one

300 gallon (1200 liter) drum. The RH supply unit has a local pneumatic layout panel.

General Description

System Components

(continued)

NOTE: The paragraphs that follow describe the components for the LH pump supply unit only. The descriptions are the same for the RH pump supply unit.

D

The pumps evacuate material from the drum.

D 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.

D 3/8” npt air filter (F) filters air to the pneumatic layout panel. The 5 micron filter removes particles, such as dust, moisture, foreign matter and other contaminants from the compressed air.

D Bleed sticks (H) are removed to allow air trapped between the top of the material and ram plate to be evacuated. Typically, they are removed and the ram plate is lowered until the material is evident in the port. They are replaced before pumping begins.

D Vent cylinders (K) open to allow air back under the follower plate while it is being removed from an empty drum. Care should be taken to keep these vents clean. If vents become clogged a vacuum can be created behind the follower plate and result in the explosive removal of the plate from the empty drum.

Pneumatic Layout Panel (G)

The pneumatic layout panel includes the following system components. For more information, refer to the

Pneumatic Diagram on page 42.

D

Main Air Inlet Valve (at E) is used to open or shutoff the air supply to the entire supply unit.

D Pump No. 1 Air Regulator controls pump speed and outlet pressure for pump no. 1 by adjusting the air pressure to the pump.

D Pump No. 1 Pressure Gauge displays the amount of air pressure supplied to pump no. 1.

D Pump No. 1 Start

D Pump No. 2 Start

D Pump No. 2 Air Regulator controls pump speed and outlet pressure for pump no. 2 by adjusting the air pressure to the pump.

D Pump No. 2 Pressure Gauge displays the amount of air pressure supplied to pump no. 2.

D Follower Vent Open switch is activated to open the vent to relieve container pressure. The follower switch has two settings.

-In the AUTO setting, when the Ram Position switch is placed in the RAISE position, the vent valves open after a short delay. This allows air back under the follower plate, preventing the creation of a vacuum under the plate. The delay ensures that the downward force on the follower plate can be overcome and prevents material from flowing past the vents.

-In the OPEN position the vents open after a short delay and remain open to facilitate cleaning. The selector should be returned to the AUTO setting immediately after cleaning is complete. If the valve is left OPEN the vents may open when the Ram Position switch is placed in the UP position and material may flow past the vents onto the top of the follower plate.

D Ram Up pushbutton turns on air pressure to raise the follower plate.

D The Ram Position Switch performs the following three functions:

-Place the switch in the RAISE position to enable the Ram Up Position Switch.

-Place the switch in the HOLD position to hold the follower plate in the current position.

-Place the switch in the LOWER position to lower the follower plate.

Prepare the Operator

All persons who operate the equipment must be trained in the safe, efficient operation of all system components as well as the proper handling of all fluids.

All operators must thoroughly read all instruction manuals, tags, and labels before operating the equipment.

System Startup

There are a series of steps that must be followed in sequential order to startup the system.

System Operation

Depending upon the system setup, at any time during operation, the operator can:

D Stop the pumps and relieve ram pressure at the LH supply unit.

D Stop the pumps and relieve ram pressure at the RH supply unit.

D

Shutdown the system.

To load the drum into the supply unit, the follower plate must be raised and the bleed stick removed at the supply unit. The follower plate is lowered by the operator directly into the drum, the bleed sticks are replaced. The follower plate is pressurized, the pumps are turned on and material is pumped from the drum through the outlet ports on the pumps via a supply hose to one or more targeted applications.

Supply Unit Operation

The Uni-Drum supply system can be setup to alternate between the LH and RH supply units. This dual supply system setup virtually eliminates material replenishment downtime.

Overview

The Uni-Drum supply system uses two air driven reciprocating pumps on the LH supply unit and two air driven reciprocating pumps on the RH supply unit.

Each supply unit pumps material from a 300 gallon

(1200 liter) drum.

The Uni-Drum supply system allows the operator to load the material drum into the RH supply unit while the LH supply unit drum is being emptied. When the supply unit changeover occurs, the operator unloads the empty drum at the LH supply unit while the RH supply unit drum is being emptied. The cycle is repeated as many times as needed.

General Functional Description

The LH and RH supply units can operate at the same time or as independent units. Generally, the Uni-Drum system is setup to operate as redundant units. This means that the RH unit is held in reserve on standby until the drum underneath the LH unit has been emptied, and vice versa.

Operating a redundant system allows the operator to maintain a continuous supply of material without interruption. The operator is afforded sufficient time to replace an empty drum at one supply unit while the drum at the other supply unit is being emptied.

System Shutdown

For system shutdown, the operator turns off the pumps and depressurizes the system. Depending upon the type of material, the operator may choose to raise the follower plate from the drum or keep the follower plate lowered in the drum to prevent the material from being contaminated. Some materials will harden or congeal when exposed to air or used past their shelf life.

Material should be kept covered when it is not being used and uncovered when it is ready to use.

4. Using an overhead lifting device, attach and secure a chain capable of lifting the weight of the pump assembly to the eye at the top of the air motor.

12. Remove the gasket and o-ring (items 32 and 33) from the pump adapter. They should be discarded and replaced when the pump is reinstalled.

NOTE: For effective pump removal, the lifting point must be directly above the pump and capable of moving sideways. The lifting action should be the

“chain fall” type that allows a slow upward and downward movement.

13. Clean excess and hardened material from the pump adapter on the follower plate.

NOTE: Check the Technical Data page in the separate pump manual to find the weight of the pump being serviced. For example, Graco Premier 45:1 SST Pump

(222939) weighs 240 lb (109 kg) per Form 308148.

14. Ensure that material is not rising through the pump adapter in the follower plate. If material is flowing upward, move the RAM POSITION switch to

RAISE until the flow stops, then move the switch back to HOLD.

5. Detach the air hose from the air motor.

15. Move the pump assembly to a suitable work area and repair the pump using the appropriate Graco

Instruction Manual.

6. Detach the fluid supply hose at the pump outlet.

NOTE: When loosening the pump and the air motor fasteners in steps and below, ensure the chain slack is taken up to prevent the pump assembly from falling.

7. On the follower plate adapter, loosen and rotate or remove four lugs and hex bolts holding the flange of the pump lower .

Pump Installation

(Refer to System Parts Diagram; page 38.)

1. When the pump is serviced and tested and ready to be replaced in the Uni-Drum Ram, perform the steps of the Pump Removal procedure in reverse order.

8. On the underside of the air motor, remove the bolts securing the air motor to the motor support brackets. It may be necessary to move or remove some brackets for effective pump removal.

2. It is recommended that the pump be tagged with the type and date of repair and the name of the technician who performed the repair.

9. Detach any other connections to the pump assembly to ensure the pump is free of attachments before removal. Possible connections include:

3. Before returning the reassembled pump to production use, it must be primed with material and air removed from the material. Follow the

Pump Instruction Form and the pump material bleeding procedure from the Drum Changing

Procedure on page 25 .
