Installation

The air motor is capable of operating in a clockwise or counterclockwise direction, depending on where the air regulator is mounted.

• When the air regulator is installed in one of the two lower ports on the motor, a clockwise rotation results, as viewed from the top of the motor.

• When installed on either side in one of the two upper ports, a counterclockwise rotation results.

• The port opposite the regulator must be plugged for the motor to operate.

The air regulator, mufflers, air gauge, nipple connector, and swivel connector are not factory installed. Follow the directions below to install these items:

1.

Screw the swivel connector (F) into the desired port (upper or lower) in the motor (M).

2.

Screw the nipple connector (G) into the air regulator (H) outlet. Note arrow directions on the regulator.

3.

Attach the air regulator by screwing it into the swivel connector.

4.

Install a plug (E) in the port opposite the regulator

(this is necessary for motor operation).

5.

Attach the air gauge (J) by screwing it into the hole in the top of the air regulator.

6.

Install a plug (E) in the regulator in the port opposite the air gauge.

7.

Screw one muffler (D) into the top of the motor.

8.

Screw the second muffler into the open port on the far side of the motor from the regulator.

9.

Installation

To reduce the risk of fire and explosion, always maintain a minimum of 1 in. (25.4 mm) clearance between the rotating agitator parts and the container to prevent sparks from contact.

1.

Mark and drill holes in the cover to mount the agitator. For dimensions, see

Mounting Hole Layouts, page 42 .

2.

Install the agitator in the cover of the fluid supply tank with the gasket (29) in place. See:

Model 25C528, page 25

Model 25C533, page 26

Model 25M481, page 27

3.

Position the air motor so the air line easily attaches to the air regulator inlet without obstructing any other system components.

4.

Bolt in place (mounting bolts not included).

To install the agitator in the container cover, lower the shaft (2) with folding blade assemblies (5, 6) through the drum bung hole, then screw the bung adapter (4) into the bung hole. See

Model 25C530, page 30 .

Position the air motor so the air line easily attaches to the air regulator inlet without obstructing any other system components.

Due to variability in drum heights, the lowest set of blades may contact the bottom of the drum. If the bung adapter (4) does not fully seat, or if resistance is felt when installing the agitator, move the blades up the shaft.

To move the blades, loosen the setscrews (SS) in the coupler and slide the assembly up or down to the desired position. The setscrew must always remain on the top, with the blades hanging down, so the blades are able to pass into and out of the bung hole.

Mount the agitator on the edge of the drum or tank and securely tighten the clamp screw (6). Squeeze the end of the retainer (17) to set in place. See

Model 25C529, page 28

.

To adjust the angle of the agitator in the drum, loosen the bracket screw (4), and position the air motor so the air line easily attaches to the air regulator inlet without obstructing any other system components.

Figure 1 Adjustable Blade Assemblies

Install the agitator in the container cover by screwing the helix (5) through the drum bung hole and screwing the agitator housing (3) into the bung hole. Torque the socket head screw (2) to 150–170 in-lbs (17–19 N•m). Torque the hex head cap screw (14) to 80–100 in-lbs (9–11 N•m). See

Models 25C534, 25C535, page 29

.

Position the air motor so the air line easily attaches to the air regulator inlet without obstructing any other system components.

To reduce the risk of fire and explosion, when using a modified drum, check that there is no interference between the base of the drum and the shaft of the agitator to avoid sparks from contact.

Keep the agitator tightly mounted to the drum bung to prevent damage to the threads from vibration.

3A4792G 9

Installation

If the agitator is used on a drum with an off-center bung and the blades contact the side of the drum, the angled adapter 16H294 must be used.

1.

Thread the locking ring (28) onto the angled adapter (27) by hand, as far as it will go.

2.

Thread the angled adapter into the bung until it bottoms out, then back it out until the widest portion of the adapter top is pointing just to the left of drum center.

See the following sections for part information:

Models 26B618, 26B619, page 35

Models 26B630, 26B631, 238250, page 33

Models 26B632, 26B633, page 37

Mount the drum cover as described in manual

306287. The elevator must be in the down position when you do any work on the elevator, agitator, or drum cover assembly. Do not go under the elevator when it is raised. Proceed to step 1 in

Installation With or Without an Elevator, page 11 .

Figure 2 Angled Adapter Just Left of Center

3.

Turn down the locking ring until it contacts the drum. Use an appropriately sized pipe wrench or adjustable wrench to tighten the adapter until the widest portion of the adapter top is in line with the drum center.

If your system does not have an elevator, install the

Handles Kit 237524 to facilitate handling the drum cover and agitator. Two people are needed to safely lift and move the drum cover and agitator. Place two standard 55 U.S. gallon (45 Imperial gallon) barrels

14 in. (36 cm) apart. Center the drum cover on the barrels with the Graco logo centered and facing you, as shown in the following figure. Proceed to step 1 in

Installation With or Without an Elevator, page 11 .

3A4792G

Installation

1.

Slide the agitator shaft through the large hole in the center of the drum cover.

2.

Rotate the agitator so that the air motor is to the left of the shaft, as shown in

Figure 3

. In this position, the three tapped holes in the bottom of the agitator align with the three through holes in the drum cover.

3.

Thread the three hex head screws (25) up through the drum cover and into the agitator.

Torque the screws to 75 in-lb (8.4 N•m).

4.

Assemble one pair of agitator blades (28) so that the four through holes in the blade halves are lined up. For blade orientation, see

Models 26B630, 26B631, 238250, page 33

and

Models 26B632, 26B633, page 37

.

5.

Push four cap screws (31) through the four holes in the blades, and start the lock nuts (32) onto the cap screws.

6.

Slide the loose blade assembly up the shaft, and position it approximately 13 in. (33 cm) from the bottom of the shaft.

7.

Tighten the four lock nuts (32) evenly to draw the blades together until they are tight on the shaft.

Torque the locknuts to 50–55 in-lb (5.6–6.2 N•m).

A gap will remain between the blade halves.

8.

Repeat steps 4 and 5 with the second pair of agitator blades.

9.

Position the second blade assembly near the bottom end of the shaft, but not on the bottom plug (20).

10. Rotate the lower blade assembly so that it is oriented 90 degrees relative to the upper blade assembly. Torque the lock nuts (32) to 50–55 in-lb (5.6–6.2 N•m). A gap will remain between the blade halves.

1.

Determine which size adaptor nut (20) is needed.

The adapter nuts in the kit are double-sided so that each adaptor nut fits two agitator shaft sizes.

Select the size you need by placing the adaptors onto the built in agitator shaft in the drum. Use the smallest size that fits. There should only be a small amount of slop between the adaptor nut and the shaft.

2.

Thread the adaptor into the gearbox output shaft

(6) with the side you are going to use pointed down. Tighten it using the wrench flats.

3.

Place the threaded bung housing adaptor (34) onto the gearbox and align the bolt holes.

4.

Thread the three bolts (28) into the gearbox and torque to 10 ft-lb (13.5 N•m).

5.

Align the adaptor nut to engage the built-in shaft in the 55-gallon drum.

6.

Slowly screw the unit onto the threads on the center bung fitting of the 55-gallon drum. Hand tighten to secure the unit. The unit should not easily unthread from the drum.

3A4792G 11

Installation

Use this procedure to install Siphon Kit 238250. See

Models 26B630, 26B631, 238250, page 33

.

1.

Remove the top plug (5) and the bottom plug

(20).

2.

Replace the bottom plug (20) with the plain bearing (50d), and tighten the bearing with a wrench.

3.

Work the PTFE o-ring (50e) onto the siphon tube retainer (50b). Leave the retaining nut (50c) on the siphon tube retainer, but do not tighten.

Tighten the siphon tube retainer into the top of the agitator housing with a wrench.

4.

Slide the siphon tube (50a) down through the retaining nut (50c), siphon tube retainer (50b), and agitator shaft (6) until the siphon tube touches the bottom of the drum. Raise the siphon tube approximately ¼ in. (approximately 6 mm) so that it does not touch the bottom of the drum.

Hold the siphon tube at this height with one hand, and tighten the retaining nut with the other hand.

(Hand-tight is enough to hold the siphon tube in place.)

Loosen the retaining nut on the siphon tube retainer before you raise the drum cover. If you do not loosen the retaining nut, the siphon tube may make contact with the bottom of the barrel when you lower the drum cover onto a new barrel, which could damage the siphon tube or the barrel.

Operation

Personal injury, such as splashing in the eyes, may result from pressure in the tank. Always follow the

Pressure Relief Procedure, page 19

before opening the tank cover or fill port.

Personal injury or equipment damage may result from lifting/falling heavy equipment. To avoid personal injury or equipment damage:

• Do not lift the drum cover and agitator without proper assistance.

• Do not walk or stand beneath a raised elevator.

1.

Turn the air regulator knob (R) counterclockwise to start at zero air pressure.

2.

Open the air shutoff valve (SV).

3.

Use the air regulator knob (R) to adjust the agitator speed. Look through the inspection port and gradually increase the speed until you can see movement in the surface of the liquid. Do not increase the agitator speed so much that a vortex forms in the surface of the liquid. If the surface begins to vortex, decrease the agitator speed to prevent air entrainment.

Always maintain moderate agitator speed, which is approximately 50 rpm of the agitator blades.

Excessive agitator speed may cause vibration, foaming of fluid, and increased wear on parts.

Always agitate fluid thoroughly before supplying it to the dispensing equipment. Continue agitating fluid while the dispensing equipment is being supplied.

1.

Start the agitator by opening the air shutoff valve

(SV). Regulate the speed with the air regulator knob (R).

2.

Operate the agitator continuously when supplying paints or other fluids to the system.

3.

Stop the agitator by closing the air shutoff valve or by reducing pressure with the air regulator knob.

Always maintain moderate agitator speed.

Excessive agitator speed may cause vibration, foaming of fluid, and increased wear on parts.

Always agitate fluid thoroughly before supplying it to the dispensing equipment. Continue agitating fluid while the dispensing equipment is being supplied.

Fill the fluid supply container to about 3 or 4 inches

(75 to 100 mm) above the agitator blades to avoid excessive vibration that could cause damage to agitator.

18 3A4792G

Operation

To avoid damaging the equipment, do not operate the agitator at a high speed for a long period of time. Excessive agitator speed can cause foaming of fluid (making the fluid unusable), vibration, and increased wear on parts. Only agitate the fluid enough to maintain even mixing.

Agitators are used to keep solids in suspension, which assists in keeping solids from clogging the siphon tube. If solids have settled in the container, use a shaker or some other device to thoroughly agitate the fluid before installing and operating the agitator.

Below is a general procedure to find the suggested agitator speed. Consult your material supplier for specific recommendations on recommended agitation speeds.

1.

Be sure ground wire is attached. See

Grounding, page 15 .

2.

Fill the fluid supply container to about 3 or 4 inches (75 to 100 mm) above the agitator blade.

3.

Open the air shutoff valve (SV).

4.

Start the agitator by gradually turning the air regulator knob (R) to increase air pressure until a vortex begins to form in the paint.

5.

Reduce the speed slightly, then fill the fluid container.

When the container is full a vortex should not be seen. Material should only be moving at a fast enough speed to ensure adequate mixing.

6.

Operate the agitator continuously while supplying paints or other fluids to the system.

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

1.

Disconnect the air line.

2.

Close the bleed-type air shutoff valve (A) to relieve pressure to the air regulator.

Keep the agitator upright. Do not lay it on its side or upside down, or liquid may flow down the shaft and into the gear reducer area.

3A4792G 19

Maintenance

Moving parts, such as an impeller blade, can cut or amputate fingers. To reduce the risk of serious injury, always shut off the agitator and disconnect the air line before checking or repairing the agitator.

Before performing any maintenance procedure, follow the

Pressure Relief Procedure, page 19 .

Depending on the environment of the motor, periodically check the cleanliness of the air motor muffler. Dirty or clogged air mufflers result in decreased motor efficiency and may cause the motor to run irregularly. If the muffler is dirty or clogged, replace it with a new muffler.

After approximately 20 million revolutions or every three to four months (whichever comes first), grease the motor needle bearing. Recommended grease:

MOBILGREASE XHP 222 SPECIAL or equivalent with minimum flash point temperature of 399.2° F

(204° C).

1.

Follow the

Pressure Relief Procedure, page 19

.

2.

Remove the motor top cover (103).

3.

Using a manual grease gun, push grease into the 21RC fitting (102) until grease is seen below the top washer (109a).

Materials can become electrostatically charged when stirred or blended. To prevent fire and explosion, ground equipment and do not allow material to build up on agitator. Dried material could allow static build up and interfere with grounding.

Regularly check the agitator for dried material buildup. Clean using a rag soaked in solvent that is compatible with the spray material and the surfaces being cleaned. Additionally, extra precautions need to be taken if using lower conductive materials

(<1,000 pS/m) such as:

• Avoid stirring/mixing at high speeds.

• Avoid insoluble mixtures.

• When possible, increase the material conductivity with additives.

• Use liquids with a high conductivity (>1000 pS/m)

20 3A4792G

Maintenance

Each week, clean any dried fluid from around the bearing (6) area of the shaft (7) and inspect the bearing for cracking or excessive wear.

You may want to have the Bearing Replacement Kit

238251 on hand before you begin this procedure.

Bearing removal and installation instructions are included in the kit.

Each week, clean any dried fluid from around the bearing (18) and bracket (23) area of the shaft (21).

Lubricate with several drops of light oil.

Keep the agitator upright. Do not lay it on its side or upside down, or liquid may flow down the shaft and into the gear reducer area.

Each week, clean any dried fluid/material on the shaft (6) near the housing (13). If any material is on the shaft (6) within ½ in. (13 mm) of the housing

(13), it must be removed to prevent damage to the bearing seal (14*). If the flexible lips on the bearing seal are torn or worn such that they do not make contact all the way around the shaft, the seal must be replaced. A worn seal may allow foreign material into the bearing and cause premature failure. See

Servicing the Gear Reducer, page 21

for instructions on getting access to the seal and for the Bearing

Replacement Kit Part No.
