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.
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.

For safety reasons, under no circumstances should regulator fluid pressure exceed the specified
Maximum Static Pressure.
The Binks Low Shear range of back pressure regulators use either operator set spring pressure (107757-X-X) or
air pressure (107758-X-X & 107760-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. The
flushable version (107760-X-X) uses a different base which does not contain a pressure port. For system
pressure regulation at flow rates above the maximum shown, consider the larger (1½) product range based on
107754 (manual spring control) and 107755 (air control).

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, on 105577 and 105578 based units, a
pressure gauge or pressure sensor can be fitted into the gauge port 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.
Before attempting any maintenance ensure that all relevant directions for working safety are followed.•
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.

107757-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.
107758-X-X / 107760-X-X: The Pilot controlled unit operates in the same way, an increase in pilot air
pressure increases the system back pressure.
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.
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.
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 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.

Reintroduce the paint system pressure and adjust the back pressure regulator to the required setting.
1. Fully unscrew the adjusting screw to remove all paint line pressure (or exhaust the compressed air pilot
supply).
2.
Assembly Procedure
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.
107758-X-X / 107760-X-X: Pressure test with 6 bar compressed air and check for leaks.
The back pressure regulator can be serviced and maintained without removing the unit from the paint pipework.
3.
7.
8.
107757-X-X: Unscrew the 6 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 6 off bonnet screws. Remove the
bonnet complete with spring and diaphragm plate and then diaphragm.
4.
107758-X-X / 107760-X-X: For the air pilot controlled version firstly remove the 10 off screws retaining
the air pilot cap and remove with the diaphragm. Unscrew the 6 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 screws to allow the diaphragm flange to be lifted off the base. Extract the
smaller composite diaphragm.
Clean all parts as required.5.
6. 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.
