3A0591U 7

Installation

Grounding

The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit.

Pump: Connect a ground wire (Graco PN 238909) to the ground screw on the bottom cover of the air motor, under the shield. Connect the other end of the ground wire to a true earth ground.

Air and fluid hoses: use only electrically conductive hoses with a maximum of 500 ft. (150 m) combined hose length to ensure grounding continuity. Check electrical resistance of hoses. If total resistance to ground exceeds 25 megohms, replace hose immediately.

Air compressors: follow manufacturer’s recommendations.

Dispense valve: ground through connection to a properly grounded fluid hose and pump.

Location

Position the ram so the air controls are easily accessible. Ensure that there is sufficient overhead clearance when the ram is fully raised. See Repair, page 20.

Position the ram in an area with adequate access for servicing and cleaning the equipment and adjacent areas to maintain the required level of hygiene. Locate equipment away from sources of air currents, dust, or liquids derived from leakage, condensation, or aerosols.

Using the holes in the ram base as a guide, drill holes for 1/2 in. (13 mm) anchors.

Check that the ram base is level in all directions. If necessary, level the base using metal shims. Secure the base to the floor using 1/2 in. (13 mm) anchors that are long enough to prevent the ram from tipping.

Material supply container: follow local code.

Container(s) that receive material: follow local code.

Solvent pails used when flushing: follow local code.

Use only conductive metal pails, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts grounding continuity.

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

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

Installation

See FIG. 3. Air inlet size is 1/2 npt(f) on the Enclosed Air Controls and 3/4 npt(f) on the Exposed Air Controls. The integrated air controls include:

• Main air valve (BA): turns air on and off to the sys-

tem. When closed, the valve relieves pressure downstream.

• Ram air regulator (BB): controls ram up and down

pressure.

• Ram director switch/valve (BC): controls ram

direction.

• Exhaust port with muffler (BD)

• Air motor regulator (BE): Controls air pressure to

motor.

• Air motor switch/slider valve (BF): turns air on

and off to the air motor. When closed, the valve relieves air trapped between it and the air motor.

• Air assist valve (BG): turns air on and off to push

the ram plate out of an empty drum. Uses line air.

• Inflatable seal air regulator (BH): controls air

pressure to the inflatable seal.

• Inflatable seal switch (BJ): controls the inflation

and deflation of the ram plate seal.

• Air relief valve (BK): automatically relieves exces-

sive pressure.

• Seal bleed off valve (BL): bleeds air from inflatable

seal as needed for drum tapering. For Exposed Air Control Modules, See F

IG. 3. For Enclosed Air Con-

trol Modules, the valve is located inside the box. See F

IG. 4, page 16.

• Muffler with needle valve (BN): Allows adjustment

of travel rate when lowering the ram plate. Located inside the box on the Enclosed Air Control Module. Not needed with the Exposed Air Control Module because ram rate can be adjusted with the director valve.

3A0591U 13

Operation

Pressure Relief Procedure

Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from injection, splashing or moving parts. Relieve pressure when you stop pumping and before cleaning, checking, or servicing equipment.

NOTE: Do not close the main air valve until Step 6. The Enclosed Air Controls will not operate when the main air supply is in the Off position.

1. Enclosed Air Controls: See F

motor switch (BF) to off. Exposed Air Controls: See F motor slider valve (BF).

2. Back the ram director air regulator down to zero. Set the ram director switch/valve (BC) to DOWN. The ram will slowly drop.

3. Jog the director valve up and down to bleed air from ram cylinders.

IG. 3. Turn the air

IG. 3. Close the air

Setting Inflatable Seal Pressure

1. Set an empty drum on the ram base. Set the director valve (BC) to DOWN. Lower the seal into the drum to the point of the drum’s largest inside diameter.

2. Set the inflatable seal switch (BJ) to On. Adjust the seal air regulator until the seal just touches the inside of the drum.

3. Leave regulator set at this setting for this style of drum.

4. Set the inflatable seal switch to Off to deflate seal before raising the ram. Set the director valve (BC) to UP and let the ram rise to its full height.

5. Remove the empty drum.

NOTE: Use the lowest seal pressure possible to achieve desired results. Excessive seal pressure may cause the seal to roll off of the follower plate. To prevent overpressurization, a relief valve limits seal pressure to 30 psi (2.1 bar, 0.21 MPa).

4. Turn the inflatable seal switch (BJ) to off.

5. Open the fluid ball valve and/or dispensing valve to relieve fluid pressure.

6. Close the main air valve (BA).

Flush Before First Use

The sanitary pump was assembled using sanitary lubricant on moving parts and was tested in water. Flush the pump thoroughly with an appropriate cleaning solution or disassemble and sanitize the parts before using the pump. See your separate pump manual for complete flushing and cleaning procedures for a sanitary pump. Check national, state, and local codes for specific limitations.

14 3A0591U

Operation

Starting and Adjusting the Ram

• Do not inflate the seal when not installed on the follower plate. Wear safety glasses when operating the seal. Seal burst could result in injury.

• Keep hands and fingers away from the ram plate, pump fluid inlet, and lip of the fluid container when raising or lowering the ram to reduce risk of serious injury from moving parts.

1. Close all air regulators and air valves.

2. Turn on the main air supply.

3. Open the main air valve (BA), and set the ram director air regulator (BB) to 2.8 bar, 0.26 MPa (40 psi). Set the director valve (BC) to UP and let the ram rise to its full height.

4. Lubricate inflatable seal (C) with sanitary lubricant.

5. Set a full drum of fluid on the ram base, slide it back against the tube stop, and center it under the follower plate.

8. Set the director valve to DOWN. Set ram air regulator at about 40 psi (0.28 MPa, 2.8 bar). Lower the ram until the ram plate is about to enter the drum, and set the valve to neutral. Reposition the drum as necessary so the inflatable seal does not hit the drum lip.

NOTE: Enclosed Controls: To increase or decrease the speed of downward travel on the ram plate, adjust the valve on the muffler (BN) inside the control box. See F

IG. 4, page 16.

Exposed Controls: To increase or decrease the speed of downward travel on the ram plate, adjust the director valve (BC).

9. Set the director valve to DOWN, and continue to lower the ram until the ram plate contacts the fluid.

10. Set seal air pressure regulator to pressure determined in Setting Inflatable Seal Pressure, page

14. Set the inflatable seal switch to On to inflate seal.

NOTE: If fluid leaks past the seal, increase the air pressure to the seal gradually until leaking stops. To prevent overpressurization, a relief valve limits seal pressure to 30 psi (2.1 bar, 0.21 MPa).

6. Remove the drum cover, and smooth the surface of the fluid with a straightedge.

7. Secure the bag liner to the drum with tape or a strap, to prevent it from sliding into the drum.

NOTICE

Do not use drums that have side bungs or large dents with this ram. Rough bung openings or large dents will damage the inflatable seal or stop the ram plate, resulting in a runaway pump.

3A0591U 15

Operation

TI16465a

TI15715a

Starting and Adjusting the Pump

See FIG. 3, page 12.

1. Be sure the pump air regulator (BE) is closed. Set the ram air regulator (BB) to about 3.5 bar, 0.35 MPa (50 psi). Set the director valve (BC) to DOWN.

2. Start the pump as explained in the separate pump instruction manual.

3. Keep the director valve (BC) set to DOWN while the pump is operating.

NOTES ON ADJUSTING PRESSURE:

Different combinations of seal and ram pressure may be necessary for proper seal and pump operation.

• If the pump does not prime properly with heavier fluids, increase air pressure to the ram.

• If fluid is forced out around the inflatable seal, decrease pressure to the ram.

• For diaphragm pump models, adjust DOWN pressure to the minimum level, to ensure that the pump inlet balls seat properly.

NOTE: If seal pressure builds when the seal enters a tapered portion of the drum, the relieve valve will activate. Turn the seal bleed-off valve (BL) counterclockwise to open it.

Operation

Cleaning Procedure

NOTE: The following instructions are a basic procedure

for cleaning a sanitary ram.

• Be sure to follow your national and state sanitary

standard codes and local regulations.

• Use appropriate cleaning and disinfecting agents, at intervals appropriate for product processed.

• Follow cleaning product manufacturer’s instructions.

1. Remove the pump from the fluid container. Operate it to pump out as much fluid as possible.

2. Flush the system thoroughly with an appropriate cleaning solution.

3. Set the inflatable seal valve (BJ) to deflate.

4. Set the director valve (BC) to UP to raise the ram plate.

5. If needed, use air assist (BG) to help lift the ram plate.

6. Raise the ram plate until it is completely out of the drum. Remove the empty drum.

8. Pull the inflatable seal down to remove. Clean and sanitize the seal.

NOTE: Discoloration of the inflatable seal is normal. Replace the inflatable seal if the surface is compromised due to excessive wear, tears, cuts, or gouges.

9. Set the director valve to DOWN. Lower the ram plate.

10. Follow the Pressure Relief Procedure, page 14.

11. Disconnect all remaining air and fluid hoses, and remove air inlet and exhaust fittings.

12. Remove and clean the pump.

NOTE: The pump must be disassembled to thoroughly clean it. See your separate pump manual for complete flushing and cleaning procedures for a sanitary pump. Any damaged rubber parts must be replaced as they could harbor microorganisms that can contaminate the fluid.

13. Remove, clean, and sanitize the clamps (12, 13), ram plate (5) and seal (8).

14. Remove the air motor cover. Open the control box door. Wipe out any residual cleaning fluid or moisture.

15. Clean external surfaces of all parts before reassembly.

Troubleshooting

1. Follow Pressure Relief Procedure, page 14.

2. Check all possible remedies in the Troubleshooting Chart before disassembling the pump.

Problem Cause Solution

Ram will not raise or lower. Closed air valve or clogged air line. Open, clear.

Not enough ram air pressure. Increase. Worn or damaged piston. Replace. Hand valve closed or clogged. Open, clear.

Ram raises and lowers too fast. Air pressure is too high. Decrease.

Travel rate is not properly adjusted. Exposed Air Controls - open the

director valve less for slower travel, more for faster travel. Enclosed Air Controls - open the needle valve on the muffler more for slower downward travel, less for

faster downward travel. Air leaks around cylinder rod. Worn rod seal. Replace. Fluid squeezes past ram plate wip-

ers.

Pump will not prime properly or pumps air.

Air assist valve will not hold drum down or push plate up.

Seal pressure builds when drum tapers, activating the automatic pressure relief.

Ram air pressure too high. Decrease ram pressure. Worn or damaged wipers. Replace. Inflatable seal pressure too low. Increase seal pressure Closed air valve or clogged air line. Open, clear. Not enough air pressure. Increase. Worn or damaged piston. Replace. See pump manual. Hand valve closed or clogged. Open, clear. Hand valve is dirty, worn, or dam-

aged. Closed air valve or clogged air line. Open, clear. Not enough air pressure. Increase. Valve passage clogged. Clean. Seal bleed-off valve (BL) is closed Open. See Integrated Air Controls,

Clean, service.
