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.

F

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.

• 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

IG. 5.

Operation

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.

Maintenance

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.
