Part

Sheet

The Binks Exel Pumps have horizon-

tally opposed positive displacement

pistons connected to a common

reciprocating air motor piston. The

pneumatically driven piston trips pilot

valves at the end of its travel producing

an air logic signal to shift the spool

valve initiating the opposite stroke.

The mechanically tripped pilot

valves contain no springs. They are

reset by a positive air signal from the

exhaust circuit. The spool valve is

air piloted and contains two exhaust

ports. Both the pilot valves and the

spool valve “un-bolt” as a cartridge,

but can also be disassembled for

repair/service.

There are no external air pilot hoses.

The air logic and exhaust ports are

completely internal. Simply mounting

the spool valve and the pilot valves

assures that the logic circuits are

connected properly.

The “4-Ball” term refers to the two

sets of ball checks. Each “set” has an

inlet and outlet check. In practice,

the inlets are connected by a common

inlet manifold and the outlets are

connected with a common outlet

manifold.

The “4-Ball” concept primes the pump

with the piston always engaging the

seal. Unlike some other horizontally

opposed piston pumps, the piston

does not pull free of the displacement

chamber piston seal to allow prime.

Pulling free of the piston seal for

prime is lost motion. No displace-

ment is possible from the time the

piston pulls free and then re-enters

the seal. The positive displacement

4-Ball concept insures positive

prime and increased displacement

with less energy demands. This

eliminates wasted effort which

requires higher air consumption to

displace a given volume of fluid.

GENERAL

INJECTION HAZARD

1. The sprayer pumps coatings at high pressure.

If you spray yourself or anyone else at close

range, the stream of material can puncture

the skin and cause great harm (possible

amputation).

2. NEVER point the spray gun at yourself or

anyone else. The tip guard provides some

protection against injection injuries, but is

mainly a warning device. NEVER remove

the tip guard. NEVER point the spray gun

at your hands, fingers, or body. ALWAYS

keep the spray gun trigger safety catch

locked in the OFF position when not in use.

3. DO NOT cover the tip guard and attempt to

“blow back” fluid. This is not an air sprayer.

4. If injury occurs, see your doctor

immediately! DO NOT TREAT THIS AS

ASIMPLE CUT. Inform your doctor

specifically of what fluid was injected.

AVOID STATIC SPARKING

Static electricity charge builds up by high

velocity liquid flowing through a hose during

flushing, cleaning, or spraying operations.

Proper grounding of the airless system safely

dissipates this charge.

All high pressure airless systems must be

grounded to avoid dangerous static sparking,

explosion, or fire when spraying or flushing

with flammable liquids.

1. Use Binks NO-WIRE conductive hose in all

airless spraying operations. Be sure gun and

hose have continuity. Check continuity

weekly with ohmmeter. Overall (end to end)

resistance of unpressurized hose must not

exceed 29 megohm (max.) for any coupled

length or combination of hose lengths.

2. Make sure the pump is grounded.

NEVER operate the unit when it is on a

non-grounded platform.

3. When flushing or cleaning with a

combustible solvent, always use an open

metallic container for receiving the waste

solvent. Ground the solvent receptacle.

4. Bond the spray gun to the waste container

with a grounding wire. Be sure there is good

metal to metal contact.

5. ALWAYS remove spray tip when flushing

the system. Operate the pump at the lowest

possible pressure.

GENERAL WARNINGS

1. NEVER leave a pressurized sprayer

unattended.

2. DO NOT use fluids, coatings, or chemicals

that are not compatible with nylon hoses.

3. Periodically inspect all hoses for leaks

and/or abrasions and tighten all connections

before use. DO NOT ATTEMPT TO

REPAIR a defective hose. REPLACE it

with another conductive hose.

4. Follow all warnings and precautions of the

coating and solvent manufacturers.

5. ALWAYS relieve pressure in the system by

turning bypass valve to BYPASS or

triggering spray gun before disassembly of

any component parts.

REPLACEMENT PARTS

The pump is designed to use authorized parts

only. When using this pump with parts that do

not comply with the minimum specifications

and safety devices of Binks, the user assumes

all risks and liabilities.

AIR/HYDRAULIC AND LUBE

REQUIREMENTS

Air Operated Pumps

1. Filtered and oiled air will allow the pump to

operate more efficiently and yield a longer life

to operating parts and mechanisms.

2. Use an air regulator on the air supply to

control the pump cycle rate. This will help to

prolong the life of the pump.

3. Supply the air lubriator with a good grade of

SAE 90 wt. non-detergent oil and set the

lubricator to a rate not to exceed one drop per

minute.

Hydraulic Operated Pumps

Hydraulic motors will require normal

maintenance. Do not allow contaminants to

enter the hydraulic motor.

TRANSPORT AND STORAGE

1. Store in a dry place; do not remove product

from box during storage.

2. Do not remove protection caps from inlet and

outlet prior to installation.

3. Do not drop or damage box; handle with care.

INSTALLATION

1. Mount the pump as required for the application.

(For example: Wall mount, floor mount,

ram, etc.)

2. AIR OPERATED PUMPS: Exhaust

silencer kits are available for these pumps.

Mount exhaust silencers or pipe exhaust

away as required to a safe location. Install a

ground wire to the air motor ground lug.

3. Connect fluid hose to pump outlet. In most

cases, a pipe sealant should be used on

thread connections. Tighten all fittings.

FLUSHING

1. Turn the motor inlet regulator pressure control

knob to “0” (zero) pressure setting.

2. Immerse lower pump end or fluid hose into a

bucket of solvent.

3. Turn the motor inlet regulator pressure control

knob and allow pump to cycle.

4. Circulate solvent through pump until it is

thoroughly cleaned.

START-UP

1. Turn the motor inlet regulator pressure control

knob until motor starts to cycle.

2. Allow pump to cycle slowly until it is primed

and all air is purged from the fluid hose or

dispensing device.

3. Turn off dispensing device and allow pump to

stall. Re-check the fittings and tighten as

necessary.

4. Open dispensing device and allow pump to

restart.

5. Adjust the motor inlet regulator as required to

obtain desired operating pressure and flow.

SHUTDOWN

1. it is good practice to periodically flush the

entire pump system with a solvent that is

compatible with the material being pumped,

especially if the material being pumped is

subject to “settling-out” when not in use for a

period of time.

2. AIR OPERATED PUMPS: Disconnect the

air supply from the pump if it is to be

inactive for a few hours.

SERVICE

1. Keep good records of service activity and

include pump in preventive maintenance

program.

2. Check the material and air/hydraulic hoses

for any weakness, and replace if necessary.

MULTIPLE PUMP SETUPS

The Binks Exel Pump is a super-quiet pump

that exceeds OSHA requirements. However,

multiple pump installations can contaminate

the atmosphere within a closed room, especially

when using a lubricator.

It is important when using multiple pumps that

each pump exhaust port be hosed to a common

exhaust plenum tube and piped to atmosphere

outside of the room with provisions for salvaging

the lubricant oil. Breathing of oil laden exhaust

air must be avoided as a health hazard. If there

is any exposure, or if any doubt exists concerning

the exhaust conditions, seek medical and/or

technical help immediately.

There is generally no lubrication required other

than the o-ring lubricant which is applied during

assembly or repair. If a lubricant is used, do not

exceed one drop per 30 cycles (or one drop

each 14 cubic feet of air used).

NOTE

Flush the pump with a solvent compatible

with the material to be pumped.

NOTE

Important: Using an unapproved oil

will void any and all warranties.

Use Binks Part #207-11155 Pneumatic

Powered Lubricant.

HALOGENATED HYDROCARBON SOL-

VENTS CAN CAUSE AN EXPLOSION

WHEN IN CONTACT WITH ALUMINUM

COMPONENTS OF A PRESSURIZED OR

CLOSED FLUID SYSTEM (PUMPS,

HEATERS, FILTERS, etc.)

The same possibility of an explosion is possible

with the galvanized coatings in pressure tanks.

The possibility of a non-flammable explosion

increases greatly at high operating temperatures.

The explosion could be of sufficient strength to

cause bodily injury, death, and substantial

property damage.

Cleaning agents, coatings, or adhesives may

contain HALOGENATED HYDROCARBON

SOLVENTS. CHECK WITHYOUR SOLVENT

AND PAINT SUPPLIER.

If you are now using a Halogenated Hydrocarbon

Solvent in a pressurized fluid system with

aluminum components or galvanized wetted

parts, the following steps should be taken

immediately:

1. Remove all pressure; drain and disconnect

the entire system.

2. Inspect and replace all corroded parts.

3. Contact your solvent supplier for a NON-

HALOGENATED SOLVENT to flush and

clean the system of all residues.

HALOGENATED Solvents are defined as any

hydrocarbon solvent containing any of the

following elements:

CHLORINE “CHLORO” (Cl)

BROMINE “BROMO” (Br)

FLUORINE “FLUORO” (F)

IODINE “IODO” (I)

Of those listed, the Chlorinated Solvents will

most likely be the type used as a cleaning agent

or solvent in an adhesive or coating. The most

common are:

METHYLENE CHLORIDE

1,1,1, TRICHLORETHANE

PERCHLORETHYLENE

Although stabilizers have been added to some

of the solvents to reduce their corrosive effect,

we are aware of none that will prevent these

solvents from reacting under all conditions

with aluminum components or galvanized

coatings.

Previous use of the solvents under pressurized

conditions, without incident, does not necessarily

indicate that it can be considered safe.

Models 41-27045 and 41-27120 Exel Pumps

are constructed with components of aluminum alloy

and SHOULD NOT be used with any

Halogenated Hydrocarbon solvents.

TYPICAL INSTALLATION: Binks 4.5:1 EXEL AIR POWERED PUMP

The general arrangement of a typical installation as

depicted in the diagram is advisory only. Your particular

installation may require siphon pressure or gravity feed

supply to the pump; and the mounting of the pump to a

vertical surface or wall may require reinforcement back-up.

Please contact your Binks Representative for assistance in

planning your system. Be sure that you comply with all

federal, state, and local codes before installation.

Be sure to mount the pump securely and to position the

pump above the floor at a convenient height to allow for

maintenance, visual observation, and periodic inspection.

Use a compatible thread compound on all tapered male

pipe threads to guard against leakage and to lubricate

threads for assembly.

The wall mount bracket is included with all Exel pumps.

Pump geometry positions air valve and outlet manifold to one

side, allowing wall mounting without the need for a shelf.

Drum cover, shelf, cart, or stand-pipe mounting is

accomplished using the optional base mounting bracket’s

(41-3198) 4-hole pattern. The center clearance hole will

easily accommodate a 1" pipe.

DISASSEMBLY

1. Follow the Pressure Relief Procedures and Warnings on

page 11.

2. Disconnect the air and fluid lines, remove the pump from its

mounting, and place it on a shop bench. A vise will be nec-

essary for this procedure.

3. Mount pump using the integral air motor mounting pads.

Use all four holes!

4. Remove outlet and siphon manifolds (34) from the pump by

loosening/removing the threaded fasteners. During removal,

capture the o-ring seals as the siphon manifold drops away

from the pump. The upper manifolds are designed with two

identical tube halves to provide for the interchangeability of

parts. This greatly reduces the parts inventory.

5. Remove the upper ball check block body (23) by removing

the four socket head cap fasteners (29) from the exposed

cavities. Carefully remove the cage, o-ring and body.

Check for damage. It is poor economy to re-use o-rings;

they should not be re-used. Remove the check-ball (21) and

the seat (19). Again, check for wear or damage and replace

if necessary.

6. Inspect the UHMW ball stop in the cage for excessive wear.

If there is exposed metal, replace the nylon ball stop to con-

tinue the quiet pump operation.

7. Remove the lower ball check housing by removing the four

socket head cap screws (28). This assembly is quite similar

to the upper ball check assembly. In this case, the ball, seat,

and cage are removed as one unit. Care must be taken not to

drop the cage or ball from the housing.

8. Remove the fluid piston housing assembly by removing the

four hex head screws (54). Gently wiggle the housing until it is

free from the seal. Remove the piston seal (17) and set it into

the housing. The seal should also be examined for possible

damage. Now pry off bolt cover (82) and remove the piston

retaining bolt (16) and slide the piston (15) off of the rod (10).

9. Remove the four socket head cap screws (48) that secure the

chamber (14) to the air motor cover plate (6). Remove the

bellows retaining nut (13) and pull bellows (12) off shaft

(10). Slide alignment ring (11) off shaft (10). Remove the

brass quad seal retaining ring (9) with a specially keyed

wrench part no. 207-11020 (not included). Next, with a

hook tool, remove the first quad seals.

10. With an extended hex socket key, remove the pilot valve

assembly (42). Remove the three o-ring seals.

11. The disassembly of the pilot valve is necessary on an occasion-

al basis to check for possible wear and damage.

12. Remove the air control valve (52) by removing the four socket

head cap screws (53). Careful removal will prevent the possible

loss of o-ring seals that may fall out.

13. To disassemble the air control valve, remove the two flat

head socket cap screws and covers from each end. All parts

are interchangeable left to right. Next, push the entire spool

assembly out of the housing.

FIRE OR EXPLOSION HAZARD: Binks 4.5:1 EXEL AIR POWERED PUMP

SERVICE: Binks 4.5:1 EXEL AIR POWERED PUMP

GROUNDING THE PUMP

Installation of the ground wire attachment to a metallic portion

of the pump must insure a secure metal-to-metal contact. The

ground wire must be 12 gauge minimum. A clamp must be

attached to a true earth ground and an instrument test must be

done to verify a ground. Mounting is the user’s responsibility.

SAFETY CONSIDERATIONS

The Exel Pump has no exposed moving parts that can create

possible hazards to personnel. However, there are some safety

points to consider:

1. Exhausting air from a motor cycling with the mufflers

removed can exceed OSHA limits. Thus, never operate the

pump without proper muffling.

2. Never attempt to loosen or remove fluid hoses, or to

disassemble the pump without first performing the pressure

relief procedure as listed on page 11.

3. Never perform any disassembly procedure unless the air

motor air supply has been turned off, the residual air has been

exhausted, and pressure in the air motor has been vented.

Should air pressure remain within the motor chamber, the

motor could cycle at any time.

4. If the manifold is not in place, keep hands and fingers clear of

the pump manifold fluid inlet and the individual inlets. The

powerful suction can cause serious bodily injury, and any

breaks in the skin can allow exposure to the chemicals in the

formulation being pumped.

5. Pressure relief procedure must be followed whenever the

pump is shut-off for cleaning, servicing, or repairing any

part of the air or fluid system. This includes

removing/installing or cleaning spray gun tips or nozzles.

The pressure relief procedure is as follows:

a. Turn off air supply to pump air motor

b. Engage gun trigger safety lock

c. If system is airless, remove gun nozzle

d. Insure the gun is “bonded” to a grounded metal waste

container. Suggested/recommended method is a ground

wire clamped between the container and the gun.

Clamping/holding a metal part of the gun in firm and

constant contact with the metal container is another

acceptable method. While continuing to ground the gun

to the container, disengage the gun safety and trigger the

gun to remove the fluid pressure. A ball-valve, installed

in the pump’s fluid manifold, can also be used as a

convenient and effective method of relieving line fluid

pressure (also see page 12).

NOTE

Ground Wire Kit is included! Use Binks Ground Wire Kit

#41-13021

NOTE

As with most fluid handling pumps, the Exel seats are

reversible, providing for longer life.

NOTE

Nos. in parenthesis ( ) in this section refer to Item Nos. in

Parts Lists on pages 9 and 15.

See parts list for available repair kits. Parts included in a kit

are marked with a •, ▲or ■. Use all the parts in the kit for

best results. Re-use of used/suspect parts is poor economy.

SERVICE: Binks 4.5:1 EXEL AIR POWERED PUMP

The spool assembly consists of five split nylon hubs, each

with a t-ring. There are also two larger spacers, two small

spacers, a rod, and a hex nut at each end to hold the entire

assembly together. By removing one hex nut, the spool can

be disassembled. As the spool is being disassembled, all

parts should be inspected for possible wear.

14. The air motor cover plate (6) is held to the air motor with ten

hex head cap screws. With the screws removed, the cover plate

can then be slid off the piston rod (10). Be careful not to damage

the o-ring seal (5) during the procedure. For best results, the

o-ring can be reseated in the air motor housing for safe keeping.

Next, remove the nylon spacer (8) and the second quad seal.

15. Pull or push the air piston assembly (2, 3, 4, 10) at a slight

angle from the air cylinder (1). Inspect quad-ring (3) for wear

or damage or replace.

RE-ASSEMBLY

1. Before installing o-rings, lubricate with factory approved

grease or petroleum jelly on air logic assembly parts only.

This will ensure a good seat and help to protect o-rings. Lube

quad-ring (3) with approved grease and carefully install around

the air motor piston (2). Insert piston assembly (2, 3, 4, 10) at a

slight angle into the air motor cylinder (1), then straighten.

Carefully install the cover plate o-ring in the groove. Be sure

that it is seated firmly. The bolts should be tightened snugly.

Do not over tighten. Install quad ring seal (7), the nylon spacer

(8), the outer quad seal, and the brass retaining ring (9).

Be sure to seat the entire set, then hand thread the brass ring

part way. Then snug the seat with the specially keyed wrench.

2. Insert the pilot valve push rod (43) making sure that it is

seated properly. After packings are pre-lubricated with

petroleum jelly, install the o-rings (49).

3. To install the pilot valve, begin by inserting the wave washer

into the housing. Next, insert the first large spool. Then insert

one large and one small o-ring. Next, install the first small

spool and one large and small o-ring. Next install the second

small spool and the last large and small o-rings. The poppet

is designed with three precision by-pass slots to allow the air

to pass from one end of the chamber to the other. The poppet’s

rubber tip should be installed toward the opening in the housing.

Finally, insert the second larger spool.

4. Install the pilot valve (42) using the two socket head cap

screws (45).

5. Assemble the air control valve (52). Be sure to pre-lubricate

all parts. If all components have been checked for damage,

they can be reassembled. Note that there are five split hubs,

five t-rings, two short spacers, and two long spacers that are

held together on the rod with the two hex nuts. Assemble the

spool and housing block. Next carefully align the end caps

so that the ports match exactly. Fasten securely with the flat

head socket cap screws.

6. Install the pre-lubricated o-rings into their appropriate ports

on the air motor: the pilot valve-ports, the air motor to piston

ports, exhaust ports, and finally, the rest of the pilot valve

ports.

7. Carefully align the air control valve and secure with four

socket head cap screws.

8. Finally, install the mufflers on the air valve assembly. Assembly

of the air motor is complete. It is strongly recommended to test

run the air motor before proceeding.

9. Slide alignment ring (11) over shaft (10) and then install the

bellows seal (12) over the piston rod shaft (10) 1-11/16 inches

(1.687") from end of shaft as shown. Grasp the bellows seal

with your left hand and hold firmly while starting and

tightening retaining nut (13) until tight. Using a 1" deep

socket continue to tighten nut to approximately ten (10) ft.-lbs.

of torque.

10. Install the chamber (14) making sure that it seats properly

over the bellows (12). Next, install the four socket head cap

screws (48) with gaskets (33).

11. Install the piston (15) into the static chamber and secure

with the retaining bolt (16). Next, snap the bolt cover (82)

into the end of the piston. Seat the piston seal (17) into the

housing (18) making sure that the lip fits firmly.

Carefully place the housing with the seal, over the piston.

Press firmly until the housing seats on the chamber (14).

Install the four hex head cap screws and tighten snugly.

12. Install the upper ball check assembly. Because the seats are

reversible they can be installed either side up.

13. Install the o-ring (20), ball cage (22) and assembly housing.

Fasten with four socket head cap screws.

14. Assemble the lower ball check housing before installing on

to the pump. Begin by assembling the ball cage (22) to the

housing block (26). Next, assemble the ball seat and o-ring

and install on to the lower check cap (27). Fasten the assembly

to the underside of the pump using four socket head cap

screws (28).

NOTE

The spool rides in a precision bore. Use no metal objects

which can mar the surface of the bore.

NOTE

Lip of piston’s seal should face toward pressurized chamber

(away from air motor).

SPECIFICATIONS & OPERATION: Binks 4.5:1 EXEL AIR POWERED PUMP

OPERATION

The Exel “Dynamic” Pump incorporates

polypropylene bellows and should not be

pressure fed or even gravity fed. Pressure

fed Exel Dynamic Pumps will experience

bellows failure.

The bellows are located inside the

Dynamic chambers and act as a seal to

the air motor. The Dynamic chambers

are next to the pumping chambers.

Together, they sandwich the piston seals.

With each cycle the Dynamic chamber

draws in material from the intake mani-

fold via a 1/4" poly hose. The next

stroke returns the material back to the

manifold. This action washes and lubes

the back side of the piston seal and

keeps it clean and cool for a longer seal

life. When normal seal wear occurs,

material leaking past the piston seal

migrates into the Dynamic chamber. The

chamber then returns the leaked material

back to the inlet manifold.

When the piston seals become com-

pletely decayed the operator will notice a

drop in performance and some aeration

of material. (cavitation due to material

rushing past the worn out seal) Even if a

bellows ruptures, the Dynamic chamber

would rather suck in air than expel mate-

rial. If a Dynamic pump were left unat-

tended while pumping costly material

and complete seal/bellows failure were

to occur, it would spill only a small

amount of material. It would then begin

sucking air, the cycling would increase,

and with a Binks pump protector (Part

#41-11150) would shut down automatically.

The maximum material lost is equal to

the volume of one stroke. As long as the

pump is not pressure fed or gravity fed, no

further material loss would occur.

In the event that an Exel Dynamic must

be pressure fed, simply disable the

Dynamic feature by removing the two

hoses (40) from the bottom of the

Dynamic chambers.You must also

remove the two elbows, part number

237-781 (38), from the lower manifold

and use 1/4" NPT plugs in their place.

The Dynamic chambers are now changed

to Static chambers. The pump may now

be pressure fed. However, when piston

seals begin to decay, normal weeping

will appear at the bottom of the Static

chambers. A new hose can be attached

to guide weeping material away.

OPERATION: Binks 4.5:1 EXEL AIR POWERED PUMP

Pressure Relief Procedure

*1. Engage the spray gun safety

latch or dispensing valve lock-

out control.

2. Turn off the air supply.

*3. Disengage the spray gun safety

latch or dispensing valve lock-

out control.

*4. Hold a metal part of the gun or

valve firmly in contact with a

grounded metal (only) waste

container. Now trigger the gun to

relieve fluid pressure.

*5. Engage spray gun safety latch

again.

6. Open the pump drain valve

(required in system); use the

container to capture the drainage.

7. Allow the drain valve to remain

open until you are ready to spray

again.

*Follow procedure literature supplied with

the spray gun or dispensing valve.

If you have reason to suspect that the

spray nozzle or hose is clogged or

that all residual pressure cannot be

fully relieved after following the

above steps, VERY SLOWLY loosen

the hose end coupling with a wrench

and relieve pressure gradually,then

loosen completely. If the nozzle or

hose obstruction cannot be cleared

completely, or is suspect, replace the

nozzle or hose. Do not reuse.

Pump Flush Before Installation

The pump was factory tested with

lightweight oil. Some residue is left

in to protect the pump parts. If this

could contaminate the fluid you are

pumping, flush it thoroughly with a

compatible solvent. To start the

pump, follow the procedure in

the following section, Start and

Adjust Pump.

Start and Adjust Pump

Numbers in Parenthesis ( ) refer to

drawing below.

1. Place the suction hose (16) in the

fluid to be pumped.

2. Close the fluid drain valve (5).

3. With the air regulator (4) closed,

open both bleed-type air valves

(3) & (18).

4. Open the fluid control device

while continuing with the follow-

ing steps.

5. Slowly open the air regulator (4).

Adjust it about 5 PSI (.3 bar) at a

time until the pump runs smoothly.

6. Cycle pump slowly until all air is

purged out of the lines (fluid

flowing in a steady stream from

the fluid outlet) until the pump is

primed.

7. If you are purging:

a. Slowly cycle pump enough to

thoroughly clean both the pump

and hoses.

(Continued on next page)

NOTE

Check all fittings. Be sure they are

tight. Be sure to use teflon tape thread

sealant, which is compatible with all

fluids, on all male pipe threads.

WARNING

To reduce the risk of serious bodily injury

from moving parts, fluid injection, and

splashing in the eyes or on the skin,

always follow this procedure whenever

the pump is shut off; when checking,

repairing, or servicing any part of the

system; when installing or changing

spray nozzles; and whenever spraying

is stopped.

WARNING

To reduce the risk of fluid injection

injury, static sparking, and splashing,

read and follow the safety instruc-

tions appearing on page 2 of this

parts sheet.

OPERATION & MAINTENANCE: Binks 4.5:1 EXEL AIR POWERED PUMP

MAINTENANCE

Flush the Pump with a

Compatible Solvent

1. Flush often enough to extend life

of piston seal and to prevent fluid

from drying in the pump with

possible damage.

2. ALWAYS flush before storing.

a. If you are pumping water-based

fluid, first flush the pump with

Binks Pump Purj (follow label

instructions). Residual Pump

Purj will prevent rust from

forming. Mineral spirits or a

compatible, oil-based solvent is

another possibility.

b. Leave the Binks Pump Purj in

the pump to protect the pump

parts from corrosion.

3. For maximum protection, be sure to

eliminate all air from the system.

Tighten Threaded Connections

1. Check all hoses before each use

for wear or damage and replace as

necessary. Be sure all threaded

connections are tight.

2. Check and tighten all threaded

connections, including manifold

screws, clamps, plugs, and valve

screws at least every six months.

Check and Service the

Lubricator, Regulator, and Filter

1. Follow service instructions supplied

with air control components.

2. Do not use other than specified oil

for the oiler. Certain private label

products with exotic solvent blends

will damage internal air motor

seals and parts. For long motor life,

use an airline oiler with part no.

207-11155-1 or Shell tellus #32,

preferably non-detergent grade.

To reduce icing due to excessive

water in the air supply, use ethylene

glycol anti-freeze.

CAUTION

Never run this pump dry (without material) for prolonged

periods of time. Running the pump dry creates heat and

friction, which could damage some of the internal parts,

causing pump failure. Improper operation of the pump will

void your warranty.

WARNING

To reduce the risk of fluid injection, static sparking, and

splashing, read and follow Flushing Safety under FIRE OR

EXPLOSION printed earlier in this part sheet.

b. Close the gun or fluid control

dispensing device and air

regulator (4).

c. Back off air regulator until

gauge reads zero.

d. Remove the section hose (8)

from the solvent and place it in

the fluid to be pumped.

8. If you are going to place the

pump in service:

a. Start the pump. Be sure the

suction hose is in the supply

container and that the tube end

is below the fluid level.

b. If you are using the pump to

spray, follow the Pressure Relief

Procedure Warning on page 11,

then trigger the gun into a

grounded metal waste container

to prime the hose and install a

spray tip in the gun. Adjust the

pump pressure just enough to

completely atomize the fluid.

Higher pressures are unneces-

sary and only cause premature

nozzle and pump wear.

c. A pump in a dead-end system

will cycle upon demand only.

d. A pump in a circulating system

runs continuously and speeds

up or slows down as supply

demands.

9. If you are removing the pump from

service or the pump is to remain

idle for an extended period:

a. Flush the pump thoroughly

before shutting down, especially

if pumping a material that will

react to time or heat.

b. Remove the siphon hose from

the supply container and cycle

the pump to force fluid out of

the system. Prime the pump

with a compatible solvent and

shut off the air supply.

c. Follow the Pressure Relief

Procedure Warning on

page 11. Also, follow

the MAINTENANCE

instructions below.

CAUTION

NEVER allow the pump to run dry of

fluid. A dry pump can accelerate to a

high cycle speed, possibly damaging

itself. If pump accelerates quickly, or is

running too fast, stop it immediately.

If the supply is empty and air has been

pumped into the lines, refill the con-

tainer and again prime the pump and

lines. If pump is damaged or needs

repair, flush the pump and leave filled

with a compatible solvent. Be sure to

eliminate all air from the system.

A Pump Protector Valve is available.

TROUBLESHOOTING: Binks 4.5:1 EXEL AIR POWERED PUMP
