WARNING

EQUIPMENT MISUSE HAZARD

Any misuse of the equipment or accessories, such as overpressurizing, modifying parts, using incompatible chemicals and fluids, or using worn or damaged parts, can cause them to rupture and result in splashing in the eyes or on the skin, other serious injury, or fire, explosion or property dam- age.

•This equipment is for professional use only. Observe all warnings. Read and understand all instruction manuals, warning labels, and tags before operating the equipment.

•Never alter or modify any part of this equipment; doing so could cause it to malfunction. Use only genuine Graco parts and accessories.

•Check all equipment regularly and repair or replace worn or damaged parts immediately.

•Never exceed the recommended working pressure or the maximum air inlet pressure stated on your pump or in the Technical Data on page 32.

•Do not exceed the maximum working pressure of the lowest rated component in your system. This equipment has a 120 psi (0.8 MPa, 8 bar) maximum working pressure at 120 psi  (0.8 MPa, 8 bar) maximum incoming air pressure.

•Be sure that all fluids and solvents used are chemically compatible with the wetted parts shown in the Technical Data on page 32. Always read the manufacturer’s literature before using fluid or solvent in the pump.

•Never move or lift a pump under pressure. If dropped, the fluid section may rupture. Always follow the Pressure Relief Procedure on page 10 before moving or lifting the pump. The pump is very heavy. If it must be moved, have two people lift the pump by grasping the outlet manifold securely.

HAZARDOUS FLUIDS

Improper handling of hazardous fluids or inhaling toxic vapors can cause extremely serious injury, even death, due to splashing in the eyes, ingestion, or bodily contamination. Observe all the follow- ing precautions when handling known or potentially hazardous fluids.

•Know what fluid you are pumping and its specific hazards. Take precautions to avoid a toxic fluid spill.

•Always wear appropriate clothing and equipment, such as eye protection and breathing appara- tus, to protect yourself.

•Store hazardous fluid in an appropriate, approved container. Dispose of it according to all Local, State and Federal guidelines for hazardous fluids.

•Secure the fluid outlet hose tightly into the receiving container to prevent it from coming loose and improperly draining the fluid.

•Pipe and dispose of the exhaust air safely, away from people, animals, and food handling areas. If the diaphragm fails, the fluid is exhausted along with the air. See Air Exhaust Ventilation on page 9.

FIRE AND EXPLOSION HAZARD

Static electricity is created by the flow of fluid through the pump and hose. If the equipment is not properly grounded, sparking may occur. Sparks can ignite fumes from solvents and the fluid being pumped, dust particles and other flammable substances, whether you are pumping indoors or out- doors, and can cause a fire or explosion and serious injury and property damage.

•To reduce the risk of static sparking, ground the pump and all other equipment used or located in the work area. Check your local electrical code for detailed grounding instructions for your area and type of equipment. Refer to Grounding on page 5.

•If you experience any static sparking or even a slight shock while using this equipment, stop pumping immediately. Check the entire system for proper grounding. Do not use the system again until the problem has been identified and corrected.

•Pipe and dispose of the exhaust air safely, away from all sources of ignition. If the diaphragm fails, the fluid is exhausted along with the air. See Air Exhaust Ventilation on page 9.

•Do not smoke in the work area. Do not operate the equipment near a source of ignition or an open flame, such as a pilot light.

HALOGENATED HYDROCARBON HAZARD

Never use 1,1,1–trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in Aluminum Pumps. Such use could result in a serious chemical reaction, with the possibility of explosion, which could cause death, serious injury and/or substantial property damage.

Consult your fluid suppliers to ensure that the fluids used are compatible with aluminum parts.

Installation

General Information

•The Typical Installation shown in Fig. 2 is only a

guide for selecting and installing system compo- nents. Contact your Graco distributor or Graco Technical Assistance (see back page) for assis- tance in planning a system to suit your needs.

•Always use Genuine Graco Parts and Accessories.

•Reference numbers and letters in parentheses refer to the callouts in the figures and the parts lists on pages 24 to 25.

HAZARDOUS FLUIDS

To reduce the risk of serious injury, splashing in the eyes or on the skin, and toxic fluid spills, never move or lift a

pump under pressure. If dropped, the fluid section may rupture. Always follow the Pressure Relief Procedure Warning on page 10 before moving or lifting the pump.

•The pump is very heavy. If it must be moved, have two people lift the pump by grasping the outlet manifold (103) securely. See Fig. 3 on page 8.

Tightening Screws 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.

Grounding

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 4.

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 equip- ment. Ground all of this equipment:

•Pump: Connect a ground wire and clamp as shown in Fig. 1. Loosen the grounding screw (W). Insert one end of a 12 ga (1.5 mm²) minimum ground wire

(Y) behind the grounding screw and tighten the screw securely. Connect the clamp end of the ground wire to a true earth ground. Order Part No. 222011 Ground Wire and Clamp.

•Air and fluid hoses: Use only grounded hoses with a maximum of 500 ft (150 m) combined hose length to ensure grounding continuity.

•Air compressor: Follow the manufacturer’s recom- mendations.

•All solvent pails used when flushing: Follow the local code. Use only metal pails, which are conduc- tive. Do not place the pail on a non-conductive surface, such as paper or cardboard, which inter- rupts the grounding continuity.

•Fluid supply container: Follow the local code.

Mountings

CAUTION

The pump exhaust air may contain contaminants. Ventilate to a remote area if the contaminants could affect your fluid supply. See Air Exhaust Ventilation on page 9.

•Be sure the mounting surface can support the weight of the pump, hoses, and accessories, as well as the stress caused during operation.

•For all mountings, be sure the pump is bolted directly to the mounting surface.

•For ease of operation and service, mount the pump so the air valve cover (2), air inlet, and fluid inlet and outlet ports are easily accessible.

•Rubber Foot Mounting Kit 236452 is available to reduce noise and vibration during operation.

Air Line

A bleed-type master air valve (B) is required in your system to relieve air trapped between this valve and the pump. 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. See Fig. 2.

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 acces- sories is grounded.

a. Install an air regulator (C) and gauge to control the fluid pressure. The fluid outlet pressure will be the same as the setting of the air regulator.

b.Locate one bleed-type master air valve (B) close to the pump and use it to relieve trapped air. See 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.

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

2.Install a grounded, flexible air hose (A) between the accessories and the 1/2 npt(f) pump air inlet (N). See Fig. 2. Use a minimum 1/2” (13 mm) ID air hose. Screw an air line quick disconnect cou- pler (D) onto the end of the air hose (A), and screw the mating fitting into the pump air inlet snugly. Do not connect the coupler (D) to the fitting until you are ready to operate the pump.

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 connec- tors (14) on air motor of pump.

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/N 195265) controllers.

Fluid Suction Line

1.Use grounded fluid hoses (G). The pump fluid inlet (R) is 2” npt(f). Screw the fluid fitting into the pump inlet securely.

2.If the fluid inlet 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.

3.At inlet fluid pressures greater than 15 psi

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

4. See the Technical Data on page 32 for maximum suction lift (wet and dry).

Fluid Outlet Line

A fluid drain valve (J) is required to relieve pres- sure in the hose if it is plugged. The drain valve reduces the risk of serious injury, including splash- ing in the eyes or on the skin, or contamination from hazardous fluids when relieving pressure.

Install the valve close to the pump fluid outlet. See Fig. 2.

Fluid Pressure Relief Valve

CAUTION

Some systems may require installation of a pres- sure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose. See Fig. 4.

Thermal expansion of fluid in the outlet line can cause overpressurization. This can occur when using long fluid lines exposed to sunlight or ambi- ent 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.

Air Exhaust Ventilation

FIRE AND EXPLOSION HAZARD; HAZARDOUS FLUIDS

Be sure to read and follow the warnings and precautions regarding HAZ- ARDOUS FLUIDS, and FIRE OR EXPLOSION HAZARD on page 4,

before operating this pump.

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 appropri- ate container at the end of the air exhaust line to catch the fluid. See Fig. 5.

The air exhaust port is 3/4 npt(f). Do not restrict the air exhaust port. Excessive exhaust restriction can cause erratic pump operation.

If the muffler (P) is installed directly to the air exhaust port, apply PTFE thread tape or anti–seize thread lubricant to the muffler threads before assembly.

To provide a remote exhaust:

1.Remove the muffler (P) from the pump air exhaust port.

2.Install a grounded air exhaust hose (T) and con- nect the muffler (P) to the other end of the hose. The minimum size for the air exhaust hose is 3/4 in. (19 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. See Fig. 5.

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

Operation

Flush the Pump Before First Use

The pump was tested with lightweight oil, which is left in the fluid passages to protect parts. To avoid contam- inating your fluid with oil, flush the pump with a com- patible solvent before using the equipment. Follow the steps under Starting and Adjusting the Pump.

Starting and Adjusting the Pump

WARNING

HAZARDOUS FLUIDS

To reduce the risk of serious injury, splashing in the eyes or on the skin, and toxic fluid spills, never move or lift a pump under pressure. If dropped, the fluid section may rupture. Always follow the Pressure Relief Procedure Warning at right before moving or lifting the pump.

1.Be sure the pump is properly grounded. Refer to

Grounding on page 5.

2.Check all fittings to be sure they are tight. Be sure to use a compatible liquid thread sealant on all male threads. Tighten the fluid inlet and outlet fittings securely.

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

NOTE: If the fluid inlet 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.

4.Place the end of the fluid hose (L) into an appropri- ate container.

5.Close the fluid drain valve (J). See Fig. 2.

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

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

8.Slowly open the air regulator (C) 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.

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 7 of Starting and Adjusting Pump.

2. Open air regulator (C).

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

3.Pump will operate when air pressure is alternately applied and relieved to push type connectors (14).

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

At the end of the work shift and before checking, adjusting, cleaning or repairing the system, follow the Pressure Relief Procedure below.

Pressure Relief Procedure

To reduce the risk of serious injury, including splashing fluid in the eyes or on the skin, follow this procedure when this manual instructs you to relieve pressure, when you shut off the pump, and before checking, adjusting, cleaning, moving, or repairing any system equipment.

1.Shut off the air to the pump.

2.Open the dispensing valve, if used.

3. Open the fluid drain valve to relieve all fluid pres- sure, having a container ready to catch the drain- age.

Maintenance

Lubrication

The air valve is designed to operate unlubricated, however if lubrication is desired, every 500 hours of operation (or monthly) remove the hose from the pump air inlet and add two drops of machine oil to the air inlet.

CAUTION

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

Flushing and Storage

Flush the pump often enough to prevent the fluid you are pumping from drying or freezing in the pump and damaging it. Always flush the pump and follow the Pressure Relief Procedure Warning on page 10 before storing it for any length of time. Use a compat- ible solvent.

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 impor- tant for prevention of spills or leakage due to dia- phragm failure.

                  Troubleshooting

To reduce the risk of serious injury, including splashing fluid in the eyes or on the skin, follow the Pressure Relief Procedure on page 10 when this manual instructs you to relieve pressure, when you shut off the pump, and before checking, adjusting, cleaning, moving, or repairing any system equipment.

NOTE: Check all possible problems and causes before disassembling the pump.
