SAFETY INSTRUCTION: Binks PNEUMATIC DIAPHRAGM PUMP DVP – GEMINI
Important: Read and follow all instructions, recommendations and safety precautions before using this equipment.
It is the responsibility of the employer to place this information into the hands of the operator.
FIRE AND EXPLOSION
Solvents and coating materials can be highly flammable
or combustible, especially when sprayed. Work stations
must be provided with adequate ventilation/exhaust to
prevent the build-up of flammable vapors.
Smoking and open flames must not be allowed in the
spraying or mixing areas. Fire extinguishing equipment
must be provided in the spraying and mixing areas. Users
must comply with all local and national codes of practice
and insurance company requirements governing ventilation, fire precautions, operation, maintenance and housekeeping of work stations.
!
WARNING
MAXIMUM SURFACE TEMPERATURE LIMITS
Maximum surface temperature depends on the operating
conditions of the pump and the temperature of the fluid,
do not allow the pump to run dry. Doing so may cause too
much increase in surface temperature.
Daily or weekly cleaning is recommended on the pump
surface to eliminate dust or paint building up on the
pump and remove all risk of fire or explosive ignition.
HALOGENATED HYDROCARBON SOLVENTS:
Halogenated hydrocarbon solvents, for example: 1,1,1 Trichoroethane and Methylene Chloride can chemically
react with aluminium and galvanised or zinc coated parts
and cause an explosion hazard. Read the label or Data
Sheet for the material you intend to spray.
!
WARNING
DO NOT USE SOLVENTS OR MATERIALS CONTAINING HALOGENATED HYDROCARBONS WITH THIS EQUIPMENT.
STATIC ELECTRICITY
Static electricity is generated by fluid moving through
pipes and hoses. A static spark, capable of igniting certain solvents and coating materials, could be produced by
high fluid flow rates. To prevent the risk of fire or explosion, earth continuity to the spray equipment and object
being sprayed should be maintained.
Use the specific grounding kit (item 46) on the top plate
(item 6) of the pump for connection of the ground wire
to a good earth ground source. Secure pump and all the
components of the air and fluid circuits so to avoid
vibration and generation of contact or static spark.
Check periodically continuity of electrical path to ground.
Test with ohmmeter from each parts of the pump and the
components of the pumping system to ground so to
insure continuity. Ohmmeter should show 0,1 ohms or
less. Pumping potentially explosive materials with pumps
from containers can create an explosive atmosphere
inside the container. Pump and container must be earthed
at the same source and the suction fluid tube must be
always immerged.
PERSONAL PROTECTIVE EOUIPMENT:
TOXIC VAPORS
When sprayed, certain material may be poisonous, create
irritation or otherwise be harmful to health. Always read
carefully all labels and safety performance data for the
material being sprayed and follow any recommendations.
IF IN DOUBT, CONSULT THE MATERIAL SUPPLIER
OR MSDS SHEET. The use of respiratory protective
equipment is recommended at all times when spraying.
The type of respiratory protective equipment used must
be compatible with the material being sprayed and the
level of concentration
Always wear protective eye protection when spraying or
cleaning the equipment.
Gloves must be worn for spraying or cleaning the equipment
when certain coating materials and solvents are used.
TRAINING
Personnel should be given adequate training in the safe
use and maintenance of this equipment. Training courses
on all aspects of the equipment are available. For details
contact your local representative. The instructions and
safety precautions contained in this and the literature supplied with the coating material should be read and understood before the equipment is used.
MISUSE
All spray guns project particles at high velocity and must
never be aimed at any part of the body. Never exceed the
maximum inlet air/hydraulic pressures as stated on the
pump model plate and written on service bulletin.
Be sure that hoses and connections used are able to withstand fluid pressures delivered by these pumps. Damaged
hoses could leak flammable liquids and create potentially
explosive atmospheres. Check all hoses for damage and
wear. Be certain that the pump system is clean and in
proper working condition.
Before dismantling the equipment for cleaning or maintenance, all pressures, air and material, must be isolated
and released.
Keep containers closed when not in use, inert gas media
must be pumped into the container to fill the void.
The disposal of non-metallic materials must be carried out
in an approved manner. Burning may generate toxic fumes.
The removal of waste solvents and coating materials should
be carried out by an authorised local waste disposal service.

!
CAUTION
BEFORE USE : All pumps are tested with water soluble oil.
It is necessary to clean the pump with an appropriate solvent
before use. The air supply should be clean, with oil and
moisture removed.
Use the same filtered, regulated air as used for spray
painting.
Connect the by-pass hose (57) or (62) and suction tube
(52) or (63). Make sure all connectors are tight to the
pump body and the by-pass valve.
Connect fluid hose to the outlet of the by-pass and to the
material inlet to your spray equipment.
Connect air supply hose to your spray equipment.
RECOMMENDED CONDUCTIVE HOSE SIZES
Recommended conductive hose sizes up to 10m (34ft)
long. The recommended air supply hose is 8mm (5 /16")
bore. The recommended material supply hose is 9.5mm
(3 /8") bore.
If you want to use your own hoses, you have to check
their conductivity. The fluid flow speed should be below
1m/s (39.6") if the fluid has low conductivity and the
hose liner is not conductive.
For example the hose size will be a minimum diameter of
19mm (3/4") bore if fluid flow is 17l/minute (4.49gpm).
Replacement glass lens is available – order 83-2290.
OPERATING INSTRUCTIONS
Pumps are suitable for use with all common materials,
within PH range of 4.5 to 8.5, with exception of halogenated hydrocarbon solvents and materials which contain such solvents.
1. Mix, prepare and strain the material to be sprayed
according to the paint manufacturer's instructions. Use
a lint free mesh to strain the material
2. To start and prime the pump, open the by-pass valve
and/or trigger the spray gun.
Adjust the air pressure by turning the air regulator knob
clockwise until the pump begins to cycle. Allow the
pump to operate until all the air is purged from the pump
and fluid line. Turn off the by-pass valve and release the
spray gun trigger.
Adjust the fluid pressure to obtain the required material
flow (see spray gun operation manual).
!
CAUTION
If the required material flow is small while the gun is triggered
(less than 5 cycles per minute) partially open the by-pass
valve to increase the cycle rate to a minimum of 5 cycles per
minute. This will eliminate the possibility of the pump
stalling during the spray operation.
!
CAUTION
IMPORTANT: Do not run these pumps dry. Runaway cycling
could cause diaphragms to warp and affect the pumps performance and increase surface temperature.
GROUNDING
The pump must be grounded to avoid static discharge
hazards. Electrical bond from the pump to earth should be
checked with an ohmmeter. A resistance of less than 106
Ohms is recommended.

Binks PNEUMATIC DIAPHRAGM PUMP DVP – GEMINI
CLEANING
The cleaning frequency depends on material, general
operating conditions, and running time. In general, the
pump should be cleaned at least once a day, and before a
long shut-down, to ensure a long service life. Under no
circumstance should paint be allowed to set up, settle out,
or dry within the pump. Do not flush pump dry, leave
pump under pressure to keep solvent in fluid section.
This protects against material hardening. It is advisable
to establish a regular cleaning schedule.
Clean pump with a solvent appropriate to material
sprayed as follows.
1. Close material valve to spray gun. Open by-pass valve.
2. Close air regulator. Relieve pressure from system by
triggering spray gun.
3. Supply solvent to pump instead of material. Open air
regulator.
4. Operate pump to flush paint from system. Continue
flushing until whole system is clean.
5. Close by-pass valve.
6. Open material valve to spray gun and operate gun until
clean and clear solvent appears
7. Clean exterior of pump with a solvent dampened cloth.
The pump can be stored for long periods when in a
cleaned condition
