ENIn this part sheet, the words WARNING, CAUTION and NOTE are used to emphasize important safety information as
follows:
WARNING CAUTION NOTE
Hazards or unsafe practices which could result in
severe personal injury, death or substantial property
damage.
Hazards or unsafe practices which could result in
minor personal injury, product or property
damage
Important installation, operation or maintenance
information.
WARNING
Read the following warnings before using this equipment.
READ THE MANUAL. Before operating finishing equipment, read and
understand all safety, operation and maintenance information
provided in the operation manual.
AUTOMATIC EQUIPMENT. Automatic
equipment may start suddenly without
warning.
WEAR SAFETY GLASSES. Failure to wear safety glasses with side
shields could result in serious eye injury or blindness.
PROJECTILE HAZARD. You may be
injured by venting liquids or gases that
are released under pressure, or flying
debris.
DE-ENERGIZE, DE-PRESSURISE, DISCONNECT AND LOCK OUT ALL
POWER SOURCES DURING MAINTENANCE. Failure to de-energize,
disconnect and lock out all power supplies before performing
equipment maintenance could cause serious injury or death. KNOW WHERE AND HOW TO SHUT
OFF THE EQUIPMENT IN CASE OF AN
EMERGENCY.
NOISE LEVELS. The A-weighted sound level of pumping and spray
equipment may exceed 85 dB(A) depending on equipment settings.
Actual noise levels are available on request. It is recommended that
ear protection is worn at all times while equipment is in use.
PRESSURE RELIEF PROCEDURE.
Always follow the pressure relief
procedure in the equipment instruction
manual.
INSPECT THE EQUIPMENT DAILY. Inspect the equipment for worn or
broken parts on a daily basis. Do not operate the equipment if you
are uncertain about its condition.
OPERATOR TRAINING. All personnel
must be trained before operating
finishing equipment.
EQUIPMENT MISUSE HAZARD. Equipment misuse can cause the
equipment to rupture, malfunction or start unexpectedly and result in
serious injury. PACEMAKER WARNING. You are in the
presence of magnetic fields which may
interfere with the operation of certain
pacemakers.HIGH PRESSURE CONSIDERATION. High pressure can cause serious
injury. Relieve all pressure before servicing. Spray from the gun,
hose leaks or ruptured components can inject fluid into your body
and cause extremely serious injury.
KEEP EQUIPMENT GUARDS IN PLACE.
Do not operate the equipment if the
safety devices have been removed.
STATIC CHARGE. Fluid may develop a static charge that must be
dissipated through proper grounding of the equipment, objects to be
sprayed and alll other electrically conductive objects in the dispensing
area. Improper grounding or sparks can cause a hazardous condition
and result in fire, explosion or electric shock and other serious injury.
NEVER MODIFY THE EQUIPMENT. Do
not modify the equipment unless the
manufacturer provides written
approval.
PROP 65 WARNING. WARNING: This product contains chemicals
known to the state of California to cause cancer and birth defects or
other reproductive harm.
PINCH POINT HAZARD. Moving parts
can crush and cut. Pinch points are
any areas where ther are moving
parts.

Note:
The Binks Low Shear range of back pressure regulators use either operator set spring pressure (107754-X-X) or
air pressure (107755-X-X) to control system fluid pressure upstream of the device by automatically adjusting the
level of restriction applied to the flow of fluid passing between its inlet and outlet ports. For system pressure
regulation at flow rates below the minimum shown, consider the smaller (¾) product range based on 107757
(manual spring control) and 107758 (air control).

Before attempting any maintenance ensure that all relevant directions for working safety are followed.
Outlet Inlet
•
Take the necessary safety precautions to guard against inhalation or contact with potentially hazardous,
toxic or corrosive fluids when modifying any existing fluid filled system.
Note:
•
Connect the unit into the paint system pipework in the direction indicated by the arrow on the valve body.
Always connect the unit using the correct fittings /gaskets and if a threaded fitting is used a suitable
thread compatible sealant.
1.
2. A pressure gauge should be mounted directly into the pipework on the inlet side of the unit to allow
precise adjustment for the regulated back pressure. Alternatively, a pressure gauge or pressure sensor
can be fitted into one of the two gauge ports provided on the inlet side of the regulator base.
• The back pressure regulator is tested with demineralised water or light oil before shipping, therefore the
fluid chamber should be flushed with suitable material prior to use.
Outlet Inlet
Installation
77-3253 R4 (06/2025) 10/24 www.binks.com
EN
5.
6.
107754-X-X: Turning the main adjusting screw clockwise will increase the spring pressure on the unit and
therefore the fluid back pressure on the paint system. Turning the screw anti-clockwise will decrease
back pressure.
107755-X-X: The Pilot controlled unit operates in the same way, an increase in pilot air pressure increases
the system back pressure.
7.
3.
If circulating system pressure testing is carried out with the back pressure regulator in circuit, the fluid
test pressure must not exceed 25 bar and the back pressure valve must ‘be unloaded’ have no spring
pressure (or air pressure) acting on the diaphragm.
4.
When the paint pipework is to be flushed with the back pressure regulator installed, the back pressure
regulator must not have any spring pressure (or air pressure) acting on the diaphragm.
This status must remain until the paint system has been accepted as clean and contaminant free.
Following pressure testing and flushing procedures the diaphragms should be examined and replaced if
necessary to ensure the integrity of the unit prior to use in production.
If electrically non-conductive piping is used, the regulator must be grounded to avoid a build up of static
charge which can occur if regulating non-conductive fluids. In these cases, some form of electrical
bonding strap must be fitted to the device to allow any electrostatic charge generated to be safely
dissipated.
8. Adjust the spring (or pilot air pressure) until the desired system fluid back pressure is achieved on the
pressure gauge in the BPR inlet pipework.

Air pilot pressure should be adjusted until the pressure gauge or pressure sensor at or near the regulator inlet
shows the required pressure. If no such device is fitted, then the table below can be used as an approximate
guide. Note: Data based on tests with deionised water - fluid pressures may vary from those shown when using
different fluids and flow rates.

Setting Back Pressure
77-3253 R4 (06/2025) 12/24 www.binks.com
EN
107755-X-X: Remove the 12 off screws retaining the air pilot cap then remove pilot cap with pilot
diaphragm. Unscrew the 8 off diaphragm flange attachment screws by 2 turns and pull away from the
base; this should then release any residual paint within the unit. Completely unscrew these 8 off screws
to allow the diaphragm flange to be lifted off the base. Extract the smaller composite diaphragm.
Clean all parts as required.5.
8. Reintroduce the paint system pressure and adjust the back pressure regulator to the required setting.
Reassemble by reversing the dismantling procedure shown above, fitting new diaphragms and observing
the correct torque and loctite requirements shown in the relevant diagrams on the following pages.
** Ensure diaphragms are installed white or light blue side down facing base! **
Tighten opposed screws in stages to maintain an even clamping force.
The back pressure regulator can be serviced and maintained without removing the unit from the paint pipework.
3.
7.
107754-X-X: Unscrew the 8 off bonnet screws by 2 turns and pull the bonnet away from the unit; this
should then release any residual paint within the unit. Fully remove the 8 off bonnet screws. Remove the
bonnet complete with spring and diaphragm plate and then diaphragm.
6.
Isolate the unit from the paint system pipework (and compressed air supply if applicable).
Position a ‘drip tray’ underneath the unit to minimise any paint spillage.
107755-X-X: Pressure test with 6 bar compressed air and check for leaks.
1. Fully unscrew the adjusting screw to remove all paint line pressure (or exhaust the compressed air pilot
supply).
