Installation

General Information

• The typical installation shown in FIG. 3 is only a guide for selecting and installing system components. Contact your Graco distributor for assistance 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 32 - 41.

The pump is very heavy (see Technical Data on pages 45 and 48 for specific weights). If the pump must be moved, follow the Pressure Relief Proce- dure on page 13 and have two people lift the pump by grasping the outlet manifold securely, or use appropriate lifting equipment. Never have one person move or lift the pump.

Leak Detection System

NOTE: To drain or service the pump, pull on the

quick-release pins (638e, one on each side) to allow the pump to rotate while still securely mounted to the bracket.

IG. 1: Quick-release pins for pump rotation

Grounding

NOTE: A leak detection system is included with all

approved pumps. See manual 311200 included with leak detector for leak detector installation instructions.

Tighten Clamps Before First Use

After you unpack the pump, and before you use it for the first time, check all clamps, and tighten as necessary.

Stand

NOTE: See pages 38 and 39 for parts.

1. Place the stand assembly on a level surface.

2. Mount the pump securely to the brackets using bolts provided.

Keep clear of moving parts.

Ground the pump and all other equipment used or located in the pumping area. 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. Check your local electrical code for detailed grounding instructions for your area and type of equipment.

• Pump: Connect a ground wire and clamp as shown in F

IG. 2. Loosen the grounding screw (W). Insert

one end of a 12 ga (1.5 mm²) minimum ground wire (X) behind the grounding screw and tighten the screw securely. Connect the clamp end of the ground wire to a true earth ground. To order a ground wire and clamp, order part number 222011.

FIG. 2: Ground Wire Connection

TI4736A

• 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 recommendations.

• Fluid supply container: Follow the local code.

Mountings

NOTE: The pump exhaust air may contain contami-

nants. Ventilate to a remote area if the contaminants could affect your fluid supply. See Air Exhaust Ventila- tion on page 12.

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

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

Air Line

A bleed-type master air valve (B) is required in the 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 F

1. Install the air line accessories as shown in FIG. 3. Mount these accessories on the wall or on a bracket. Be sure the air line supplying the accessories is grounded.

a. Install an air regulator (C) and gauge to control

IG. 3.

the fluid pressure. The fluid outlet pressure will be the same as the setting of the air regulator.

Installation

b. Locate one bleed-type master air valve (B)

close to the pump and use it to relieve trapped air. 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 (M). Use a minimum 3/8 in. (9.5 mm) ID air hose. Screw an air line quick disconnect coupler (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. Connecting the coupler too early can result in unintentional operation of the pump, leading to serious injury from moving parts, splashing fluid in the eyes or on the skin, and contact with hazardous fluids.

Fluid Suction Line

1. Use flexible, grounded fluid hoses (G) where possible.

2. For best sealing results, use a standard tri-clamp or DIN style sanitary gasket of a flexible material such as EPDM, Buna-N, fluoroelastomer, or silicon.

3. NOTE: Compliance with 3A sanitary standards requires DIN connections to use certain gaskets. See CCE Coordination Bulletin Number 2011-3. Two such gaskets are the Siersema Komponent System (S.K.S.), the Netherlands, and the ASEPTO-STAR k-flex gasket from Kieselmann GmbH, Germany.

4. 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. Excessive inlet fluid pressure also will shorten diaphragm life. Approximately 3-5 psi (0.02-0.03 MPA, 0.21-0.34 bar) should be adequate for most materials.

5. See the Technical Data on pages 45 and 48 for maximum suction lift (wet and dry). For best results, always install the pump as close as possible to the material source.

Air Exhaust Ventilation

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 can 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 F

IG. 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.

To provide a remote exhaust:

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

IG. 5.

2. Install a grounded air exhaust hose (T) and connect 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.

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

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.

1. Shut off the air to the pump.

2. Open any available outbound fluid valve to relieve fluid pressure from the pump.

3. If fluid is still in the outbound fluid lines, isolate this fluid as follows:

a. Close the outbound fluid valves.

b. Slowly remove the fluid connections from the

pump, and have a container ready to catch any fluid that runs out.

NOTE: If 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 fluid hose (L) into an appropriate container.

5. Close the fluid drain valve (J).

6. Back out the air regulator (C) knob, and 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 increase air pressure with the air regulator (C) until the pump starts to cycle. Do not exceed the maximum operating air pressure as listed in the Technical Data section on pages 45 and 48. Allow the pump to cycle slowly until all air is pushed out of the lines and the pump is primed.

Pump Shutdown

Sanitizing the Pump Before First Use

NOTE: The pump was built and tested using a food

grade lubricant.

It is the user’s responsibility to properly sanitize the pump before first use. It is up to the user whether this will include disassembling and cleaning individual parts or simply flushing pump with a sanitizing solution. As necessary, follow the steps under Starting and Adjust- ing the Pump below, under Flushing on page 14, or under Disassembly in the Service section on pages 21, 23, and 26.

Starting and Adjusting the Pump

1. Be sure the pump is properly grounded. See

Grounding, page 8.

2. Check connections to be sure they are tight. Tighten fluid inlet and outlet connections securely.

At the end of the work shift, relieve pressure.

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

310622ZAF 13

Maintenance

Lubrication

The air valve is designed to operate unlubricated. 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.

NOTICE

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

Flushing

Insert suction tube into cleaning solution. Open air regulator to supply low pressure air to the pump. Run the pump long enough to thoroughly clean the pump and hoses. Close the air regulator. Remove the suction tube from the cleaning solution and drain pump. Place suction tube in the fluid to be pumped.

Flush the pump often enough to prevent the fluid you are pumping from drying or freezing in the pump and damaging it. Flushing schedule will be based on what the pump is being used for. Use a compatible cleaning solution and always cycle the pump during the entire flushing process.

4. Using a brush or other C.I.P. methods, wash all product contact pump parts with an alkaline detergent at the manufacturer’s recommended temperature and concentration.

5. Rinse these parts again with water and allow parts to completely dry.

6. Inspect the parts and reclean any soiled parts.

7. Immerse all product contact parts in an approved sanitizer before assembly. Leave the parts in the sanitizer, taking them out only one by one as needed for assembly. See Check Valve Repair, page 21, and Standard Diaphragm Repair, page 23, or 3A/Overmolded Diaphragm Repair, page

26.

8. Lubricate the clamps, clamping surfaces, and gaskets with waterproof sanitary lubricant.

9. Circulate the sanitizing solution through the pump and the system prior to use. Cycle the pump as the sanitizing solution is circulated.

Tightening Connections

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

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

Routine Cleaning of Product Contact Section of Pump

NOTE: The pump and the system should be cleaned in

accordance with your state sanitary standard codes and local regulations.

1. Flush the system. See Flushing above.

2. Follow the Pressure Relief Procedure, page 13.

3. Disassemble the fluid section of the pump and

accessories. See Check Valve Repair, page 21, and Standard Diaphragm Repair, page 23, or 3A/Overmolded Diaphragm Repair, page 26.
