Contact your Graco distributor for assistance in planning a system to suit your needs.

Always use Genuine Graco Parts and Accessories.

Use a compatible, liquid thread sealant on all male threads. Tighten all connections firmly to avoid air or fluid leaks.

Tightening Threaded Fasteners Before

First Use

Before using the pump for the first time, check and retorque all external fasteners. See Torque Se-

quence, page 29. After the first day of operation, retorque the fasteners. Although pump use varies, a general guideline is to retorque fasteners every two months.

Toxic Fluid Hazard

Read Toxic Fluid Hazard on page 3.

Use fluids and solvents that are compatible with the equipment wetted parts. Refer to the Technical Data section of all equipment manuals. Read the fluid and solvent manufacturer’s warnings.

CAUTION

Safe Operating Temperatures

Minimum (all pumps): 40 F (4 C)

Maximum

Acetal: 180 F (82 C)

Polypropylene: 150 F (66 C)

Aluminum, stainless steel, PVDF: 225 F (107 C)

These temperatures are based upon mechanical stress only and may be significantly altered by pumping certain chemicals. Consult engineering guides for chemical compatibilities and temperature limits, or contact your Graco distributor.

Mountings

These pumps can be used in a variety of installations. Be sure the mounting surface can support the weight of the pump, hoses, and accessories, as well as the stress caused during operation.

Fig. 2 shows some installation examples. On all installations, mount the pump using screws and nuts.

Pumping High-Density Fluids

High density fluids may prevent the lighter non-metallic check valve balls from seating properly, which reduces pump performance significantly. Stainless steel balls should be used for such applications.

Split Manifolds

Air Line

Installation

WARNING

A bleed-type master air valve (B) is required in your system to relieve air trapped between this valve and the pump. See Fig. 2. Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury, including splashing in the eyes or on the skin, injury from moving parts, or contamination from hazardous fluids.

Installation of Remote Pilot Air Lines

1.

Refer to Parts Drawings. Connect air line to pump as in preceding steps.

2.

Connect 1/4 in. O.D. tubing to push type connectors (16) on underside of pump.

CAUTION

The pump exhaust air may contain contaminants.

Ventilate to a remote area if the contaminants could affect your fluid supply. Read Air Exhaust Ventila-

tion on page 6.

1.

Install the air line accessories as shown in Fig. 2.

Mount these accessories on the wall or on a bracket. Be sure the air line supplying the accessories is electrically conductive.

a.

The fluid pressure can be controlled in either of two ways. To control it on the air side, install an air regulator (G). To control it on the fluid side, install a fluid regulator (J) near the pump fluid outlet (see Fig. 2).

NOTE: by replacing the push type connectors, other sizes or types of fittings may be used. The new fittings will require 1/8 in. npt threads.

3.

Connect remaining ends of tubes to external air signal, such as Graco’s Cycleflo (P/N 195264) or

Cycleflo II (P/N195265) controllers.

NOTE: the air pressure at the connectors must be at least 30% of the air pressure to the air motor for the pump to operate.

Fluid Suction Line

If using a conductive (acetal) pump, use conductive hoses. If using a non-conductive pump, ground the fluid system. Read Grounding on page 8. The fluid inlet port is 1/2 in. or 3/4 in.

At inlet fluid pressures greater than 15 psi

(0.1 MPa, 1 bar), diaphragm life will be shortened.

Fluid Outlet Line

b.

Locate one bleed-type master air valve (B) close to the pump and use it to relieve trapped air. Read the WARNING above. Locate the other master air valve (E) upstream from all air line accessories and use it to isolate them during cleaning and repair.

WARNING

A fluid drain valve (H) is required in your system to relieve pressure in the hose if it is plugged. See

Fig. 2. The drain valve reduces the risk of serious injury, including splashing in the eyes or on the skin, or contamination from hazardous fluids when relieving pressure. Install the valve close to the pump fluid outlet.

c.

The air line filter (F) removes harmful dirt and moisture from the compressed air supply.

2.

Install an electrically conductive, flexible air hose

(C) between the accessories and the 1/4 npt(f) pump air inlet. Use a minimum 1/4 in. (6.3 mm) ID air hose. Screw an air line quick disconnect coupler (D) onto the end of the air hose (C), and screw the mating fitting into the pump air inlet snugly. Do not connect the coupler (D) to the fitting yet.

1.

Use electrically conductive fluid hoses (K). The pump fluid outlet is 1/2 in. or 3/4 in. Screw the fluid fitting into the pump outlet snugly. Do not over- tighten.

2.

Install a fluid regulator (J) at the pump fluid outlet to control fluid pressure, if desired (see Fig. 2).

See Air Line, step 1a, for another method of controlling pressure.

3.

Install a fluid drain valve (H) near the fluid outlet.

Read the WARNING above.

308981 5

Installation

Air Exhaust Ventilation Fluid Pressure Relief Valve

CAUTION

Some systems may require installation of a pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose.

See Fig. 1.

Thermal expansion of fluid in the outlet line can cause overpressurization. This can occur when using long fluid lines exposed to sunlight or ambient heat, or when pumping from a cool to a warm area (for example, from an underground tank).

Overpressurization can also occur if the Husky pump is being used to feed fluid to a piston pump, and the intake valve of the piston pump does not close, causing fluid to back up in the outlet line.


Read Fire and Explosion

Hazard on page 3.

Be sure the system is properly ventilated for your type of installation. You must vent the exhaust to a safe place, away from people, animals, food handling areas, and all sources of ignition when pumping flammable or hazardous fluids.

Diaphragm failure will cause the fluid being pumped to exhaust with the air. Place an appropriate container at the end of the air exhaust line to catch the fluid. See Fig. 2 .

9073A

See Venting Exhaust Air in Fig. 2. Exhaust to a remote location as follows:

1.

Remove the muffler (W) from the pump air exhaust port.

2.

Install an electrically conductive air exhaust hose

(X) and connect the muffler to the other end of the hose. The minimum size for the air exhaust hose is 3/8 in. (10 mm) ID. If a hose longer than 15 ft

(4.57 m) is required, use a larger diameter hose.

Avoid sharp bends or kinks in the hose.

3.

Place a container (Z) at the end of the air exhaust line to catch fluid in case a diaphragm ruptures.

Grounding

WARNING

FIRE AND EXPLOSION HAZARD

This pump must be grounded. Before operating the pump, ground the system as explained below. Also read the section Fire and Explosion Hazard on page 3.

The acetal Husky 515 pump contains stainless steel fibers, which makes the wetted parts conductive. Attaching the ground wire to the grounding screw (106) grounds the wetted parts. See

grounding screw on page 25.

The metal Husky 716 pumps have a grounding strip connecting the vee clamps (109). Attach a ground wire to the grounding strip with the screw, lockwasher, and nut as shown in the Grounding

Detail on page 27.

The polypropylene and PVDF Husky 515 pumps are not conductive.

When pumping conductive flammable fluids, al-

ways ground the entire fluid system by making sure the fluid system has an electrical path to a true earth ground (see Fig. 3). Never use a polypropylene or PVDF pump with non-conductive flammable fluids as specified by your local fire protection code.

US Code (NFPA 77 Static Electricity) recommends a conductivity greater than 50 x 10

–12

Siemans/meter (mhos/meter) over your operating temperature range to reduce the hazard of fire. Consult your fluid supplier to determine the conductivity or resistivity of your fluid. The resistivity must be less than 2 x 10

12

ohm-centimeters.

To reduce the risk of static sparking, ground the pump and all other equipment used or located in the pumping area. Check your local electrical code for detailed grounding instructions for your area and type of equipment.

Ground all of this equipment:

Pump: The metal pump has a grounding strip in front of the center housing. The acetal pump has a grounding screw on the top manifold. Connect the non-clamp end of the ground wire to the grounding strip or grounding screw, and connect the clamp end of the ground wire to a true earth ground. To order a ground wire and clamp, order Part No.

222011.

Air and fluid hoses: Use only electrically conductive hoses.

Air compressor: Follow the manufacturer’s recommendations.

Solvent pails used when flushing: Follow the local code. Use only grounded metal pails, which are conductive. Do not place the pail on a non-conductive surface, such as paper or cardboard, which interrupts the grounding continuity.

Fluid supply container: Follow the local code.

Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The equipment stays pressurized until pressure is manually relieved. To reduce the risk of serious injury from pressurized fluid, accidental spray, or splashing fluid, follow this procedure whenever you

Are instructed to relieve pressure

Stop pumping

Check, clean, or service any system equipment

Install or clean fluid nozzles

1.

Shut off the air to the pump.

2.

Open the dispensing valve, if used.

Operation

3.

Open the fluid drain valve to relieve all fluid pressure, and have a container ready to catch the drainage.

5.

Place the suction tube (if used) in the fluid to be pumped.

NOTE: If the inlet fluid pressure to the pump is more than 25% of the outlet working pressure, the ball check valves will not close fast enough, resulting in inefficient pump operation.

6.

Place the end of the fluid hose (K) into an appropriate container.

7.

Close the fluid drain valve (H).

8.

With the pump air regulator (G) closed, open all bleed-type master air valves (B, E).

9.

If the fluid hose has a dispensing device, hold it open while continuing with the following step.

Slowly open the air regulator (G) until the pump starts to cycle. Allow the pump to cycle slowly until all air is pushed out of the lines and the pump is primed.

Flush Pump Before First Use

The pump was tested with water. Prior to first use, flush the pump thoroughly with a compatible solvent.

Reactor feed pumps, part numbers 246484, 246485, and 257447, were tested with lightweight oil, which is left in the fluid passages. To avoid contaminating your fluid with oil, flush the pump with a compatible solvent before using the equipment. Follow the steps under

Starting and Adjusting Pump.

If you are flushing, run the pump long enough to thoroughly clean the pump and hoses. Close the air regulator. Remove the suction tube from the solvent and place it in the fluid to be pumped.

Operation of Remote Piloted Pumps

1.

Fig. 2 and Parts Drawings. Follow preceding steps

1 through 8 of Starting and Adjusting Pump.

2.

Open air regulator (G).


WARNING

The pump may cycle once before the external signal is applied. Injury is possible. If pump cycles, wait until end before proceeding.

If lifting the pump, follow the Pres-

sure Relief Procedure above.

Be sure the pump is properly grounded.

Read Fire and

Explosion Hazard on page 3.

3.

Pump will operate when air pressure is alternately applied to push type connectors (16).

NOTE: Leaving air pressure applied to the air motor for extended periods when the pump is not running may shorten the diaphragm life. Using a 3–way solenoid valve to automatically relieve the pressure on the air motor when the metering cycle is complete prevents this from occurring.

Pump Shutdown

4.

Check all fittings to be sure they are tight. Use a compatible liquid thread sealant on all male threads. Tighten the fluid inlet and outlet fittings snugly. Do not overtighten the fittings into the pump.

10 308981

At the end of the work shift, relieve

the pressure as described in Pres-

sure Relief Procedure at left.

Maintenance

Lubrication

The air valve is lubricated at the factory to operate without additional lubrication. If you want to provide additional lubrication, remove the hose from the pump air inlet and add two drops of machine oil to the air inlet every 500 hours of operation or every month.

CAUTION

Do not over-lubricate the pump. Oil is exhausted through the muffler, which could contaminate your fluid supply or other equipment. Excessive lubrication can also cause the pump to malfunction.

Flushing and Storage

Flush the pump to prevent the fluid you are pumping from drying or freezing in the pump and damaging it.

Use a compatible solvent.

Always flush the pump and relieve the pressure before you store it for any length of time.

Read Pressure Relief Procedure on page 10.

Tightening Threaded Connections

Before each use, check all hoses for wear or damage and replace as necessary. Check to be sure all threaded connections are tight and leak-free.

Check fasteners. Tighten or retorque as necessary.

Although pump use varies, a general guideline is to retorque fasteners every two months. See Torque

Sequence, page 29.

Preventive Maintenance Schedule

Establish a preventive maintenance schedule, based on the pump’s service history. This is especially important for prevention of spills or leakage due to diaphragm failure.

308981 11

Troubleshooting

Read Pressure Relief Procedure on page 10, and relieve the pressure before you check or service the equipment. Check all possible problems and causes before disassembling the pump.

NOTE: Fluid Section Repair Kit D05XXX is available. See page 22 to order the correct kit for your pump. Parts included in the kit are marked with a double dagger ( ) in Fig. 9 and in the Parts Drawings and Lists. General purpose grease 111920 and Adhesive 113500 are supplied in the kit. Service the diaphragms as follows. See Fig. 9.

Disassembly Reassembly

1.



1.

Insert a diaphragm shaft u-cup (416) and a pilot pin o-ring (1) into the bores of the center housing

(11).

2.

Remove manifolds (102 and 103) and fluid covers (101).

NOTE: Make sure all the check valve parts stay in place. See Fig. 7 on page 15.

3.

Remove one of the fluid-side diaphragm plates

(105) (whichever one comes loose first when you use a wrench on the hex of each), and pull the diaphragm shaft out of the center housing (11).

Overmolded Diaphragms: The air cover bolts may make it difficult to remove the overmolded diaphragms on the 515 pump. Use a flat surface that fits within the bolt pattern to apply pressure on one of the diaphragms to shift the diaphragm shaft to one side. Apply pressure until the other diaphragm is separated from the air cover. Rotate the separated diaphragm counterclockwise until the diaphragm assembly comes free. Pull the second diaphragm assembly and the diaphragm shaft (15) out of the center housing. (11)

4.

Use a wrench on the flats of the diaphragm shaft

(15) to remove the other fluid-side diaphragm plate

(105) from the diaphragm shaft.

NOTE: Make sure the lips of the u-cup face out of the center housing.

2.

Line up the holes in the gasket (12) with the holes in the end of the center housing (11), and use six screws (106) to fasten an air cover (113 or 114) to the end of the center housing (11). Torque the screws to 35 to 45 in-lb (4.0 to 5.1 N-m).

3.

Position the exhaust cover (13) and o-ring (4) on the center housing (11).

4.

Repeat steps 1 and 2 for the other end of the center housing and the remaining air cover.

5.

Apply medium-strength (blue) Loctite or equivalent to the threads of the fluid-side diaphragm plates

(105). Install on one end of the diaphragm shaft

(15) the following parts (see proper order in Fig. 9): air-side diaphragm plate (6), backup diaphragm

(402, used only on models with PTFE diaphragms), diaphragm (401), and fluid-side diaphragm plate (105).

Overmolded Diaphragms: Use a wrench on the flats of the diaphragm shaft (15) to remove the second diaphragm.

5.

Remove the screws (106), remove the left (114) and right (113) air covers, and remove all old gasket (12) material from the ends of the center housing (11) and the surfaces of the air covers.

6.

Remove the diaphragm shaft u-cups (416) and pilot pin o-rings (1).

7.

Inspect all parts for wear or damage, and replace as necessary.

NOTE: The words “AIR SIDE” on the diaphragm

(401), the backup diaphragm (402, used only on models with PTFE diaphragms) and the flat side of the air-side diaphragm plate (6) must face toward the diaphragm shaft (15).

Overmolded Diaphragms: Assemble the air–side plate (6) onto the diaphragm (401). The words AIR

SIDE on the air–side plate must face away from the diaphragm. Apply medium–strength (blue) thread locking adhesive to the threads of the diaphragm assembly. Screw the assembly into the diaphragm shaft (15) hand tight.

16 308981

6.

Put grease on the diaphragm shaft (15), and carefully (do not damage the shaft u-cups) run the diaphragm shaft (15) through the center housing

(11) bore.

7.

Repeat step 5 for the other end of the diaphragm shaft (15), and torque the fluid-side diaphragm plates (105) to 80 to 90 in-lb (9 to 10 N-m) at 100 rpm maximum.

Overmolded Diaphragms: The air cover bolts may make it difficult to assemble the overmolded diaphragms on the 515 pump. Two people are needed. Use a flat surface that fits within the bolt pattern to apply pressure on the diaphragm that has already been assembled. Apply pressure until the diaphragm shaft sticks out of the other end of the center housing far enough to attach the second diaphragm assembly. Screw the assembly into the shaft (15) hand tight.

8.

Install the muffler (3).

9.

Make sure all the check valve parts are in place.

See Fig. 7 on page 15.

10. Reinstall the fluid covers (101) and manifolds (102 and 103), and torque the fluid cover and manifold nuts (109) to 80 to 90 in-lb (9 to 10 N-m). See
