OPERATING AND SAFETY PRECAUTIONS
READ, UNDERSTAND, AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
EXCESSIVE AIR PRESSURE
STATIC SPARK
HAZARDOUS MATERIALS
HAZARDOUS PRESSURE
WARNING EXCESSIVE AIR PRESSURE. Can cause personĆ
al injury, pump damage or property damage.
SDo not exceed the maximum inlet air pressure as stated on the
pump model plate.
SBe sure material hoses and other components are able to withĆ
stand fluid pressures developed by this pump. Check all hoses
for damage or wear. Be certain dispensing device is clean and
in proper working condition.
WARNING STATIC SPARK. Can cause explosion resulting in
severe injury or death. Ground pump and pumping system.
SSparks can ignite flammable material and vapors.
SThe pumping system and object being sprayed must be
grounded when it is pumping, flushing, recirculating or sprayĆ
ing flammable materials such as paints, solvents, lacquers,
etc. or used in a location where surrounding atmosphere is
conducive to spontaneous combustion. Ground the dispensĆ
ing valve or device, containers, hoses and any object to which
material is being pumped.
S818831 Groundable Acetal pumps: Use the pump grounding
screw provided. Connect a 12 ga. (min. wire (kit is included to
a good earth ground source.
SSecure pump, connections and all contact points to avoid
vibration and generation of contact or static spark.
SConsult local building codes and electrical codes for specific
grounding requirements.
SAfter grounding, periodically verify continuity of electrical path
to ground. Test with an ohmmeter from each component (e.g.,
hoses, pump, clamps, container, spray gun, etc. to ground to
insure continuity. Ohmmeter should show 0.1 ohms or less.
SSubmerse the outlet hose end, dispensing valve or device in
the material being dispensed if possible. (Avoid free streaming
of material being dispensed.
SUse hoses incorporating a static wire.
SUse proper ventilation.
SKeep inflammables away from heat, open flames and sparks.
SKeep containers closed when not in use.
WARNING Pump exhaust may contain contaminants. Can
cause severe injury. Pipe exhaust away from work area and perĆ
sonnel.
SIn the event of a diaphragm rupture, material can be forced out
of the air exhaust muffler.
SPipe the exhaust to a safe remote location when pumping hazĆ
ardous or inflammable materials.
SUse a grounded 3/8" minimum i.d. hose between the pump and
the muffler.
WARNING HAZARDOUS PRESSURE. Can result in serious
injury or property damage. Do not service or clean pump,
hoses or dispensing valve while the system is pressurized.
SDisconnect air supply line and relieve pressure from the sysĆ
tem by opening dispensing valve or device and / or carefully
and slowly loosening and removing outlet hose or piping from
pump.
WARNING HAZARDOUS MATERIALS. Can cause serious inĆ
jury or property damage. Do not attempt to return a pump to the
factory or service center that contains hazardous material.
Safe handling practices must comply with local and national
laws and safety code requirements.
SObtain Material Safety Data Sheets on all materials from the
supplier for proper handling instructions.
CAUTION Verify the chemical compatibility of the pump
wetted parts and the substance being pumped, flushed or reĆ
circulated. Chemical compatibility may change with temperaĆ
ture and concentration of the chemical(s within the
substances being pumped, flushed or circulated. Consult
Bink's representative for information on chemical compatibiliĆ
ty.
CAUTION Maximum temperatures are based on mechaniĆ
cal stress only. Certain chemicals will significantly reduce
maximum safe operating temperature. Consult Bink's repreĆ
sentative for information on chemical compatibility. Refer to
PUMP DATA on page 1 of this manual.
CAUTION Be certain all operators of this equipment have
been trained for safe working practices, understand it's limitaĆ
tions, and wear safety goggles / equipment when required.
CAUTION Do not use the pump for the structural support of
the piping system. Be certain the system components are
properly supported to prevent stress on the pump parts.
SSuction and discharge connections should be flexible connecĆ
tions (such as hose , not rigid piped, and should be compatible
with the substance being pumped.
CAUTION Prevent unnecessary damage to the pump. Do
not allow pump to operate when out of material for long periods
of time.
SDisconnect air line from pump when system sits idle for long
periods of time.
CAUTION Use only genuine Bink's replacement parts to asĆ
sure compatible pressure rating and longest service life.
NOTICE Install the pump in the vertical position. The
pump may not prime properly if the balls do not check by gravĆ
ity upon startĆup.
NOTICE ReĆtorque all fasteners before operation. Creep
of housing and gasket materials may cause fasteners to loosĆ
en. ReĆtorque all fasteners to insure against fluid or air leakage.
WARNING
CAUTION
NOTICE
= 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.

GENERAL DESCRIPTION
The Bink's Diaphragm Pump offers high volume delivery even at low air
pressure. Bink's pumps feature stall resistant design, modular air motor /
fluid sections.
Air operated double diaphragm pumps utilize a pressure differential in
the air chambers to alternately create suction and positive fluid pressure in
the fluid chambers, ball checks insure a positive flow of fluid.
Pump cycling will begin as air pressure is applied and it will continue to
pump and keep up with the demand. It will build and maintain line presĆ
sure and will stop cycling once maximum line pressure is reached disĆ
pensing device closed) and will resume pumping as needed.
Models 818831 and 818836: The Acetal material used in these pumps
contains Stainless Steel fibers. It's conductivity allows it to be connected
to a suitable ground. A ground screw and ground wire kit is provided for
this.
AIR AND LUBE REQUIREMENTS
SUse a filter capable of filtering out particles larger than 50 microns on
the air supply. There is no lubrication required other than the O" ring
lubricant which is applied during assembly or repair.
SIf lubricated air is present, make sure that it is compatible with the
Nitrile O" rings in the air motor section of the pump.
OPERATING INSTRUCTIONS
SAlways flush the pump with a solvent compatible with the material
being pumped if the material being pumped is subject to setting up"
when not in use for a period of time.
SDisconnect the air supply from the pump if it is to be inactive for a few
hours.
SThe outlet material volume is governed not only by the air supply but
also by the material supply available at the inlet. The material supply
tubing should not be too small or restrictive. Be sure not to use hose
which might collapse.
SWhen the diaphragm pump is used in a forcedĆfeed flooded inlet)
situation, it is recommended that a Check Valve" be installed at the
air inlet.
SSecure the diaphragm pump legs to a suitable surface to insure
against damage by vibration.
MAINTENANCE
SProvide a clean work surface to protect sensitive internal moving
parts from contamination from dirt and foreign matter during service
disassembly and reassembly.
SKeep good records of service activity and include pump in prevenĆ
tive maintenance program.
SService Kits are available to service three separate Diaphragm
Pump functions: 1. AIR SECTION, 2. DIAPHRAGM SECTION, 3.
BALL and SEAT SECTION.

TROUBLE SHOOTING
Product discharged from air exhaust.
SCheck for diaphragm rupture.
SCheck tightness of 6) diaphragm nut or 14) bolt.
Air Bubbles in product discharge.
SCheck connections of suction plumbing.
SCheck band clamps on intake manifold nonĆmetallic models).
SCheck O" rings between intake manifold and fluid caps.
SCheck tightness of 6) diaphragm nut or 14) bolt.
Pump blows air out main exhaust when stalled on either stroke.
SCheck U" cups on 111) spool in major valve.
SCheck 141) valve plate and 140) insert for wear.
SCheck 103) sleeve and 2) O" ring on diaphragm connecting rod.
SCheck 119) O" rings on 118) pilot rod for wear.
Low output volume.
SCheck air supply.
SCheck for plugged outlet hose.
SFor the pump to prime itself, it must be mounted in the vertical posiĆ
tion so that the balls will check by gravity.
SCheck for pump cavitation Ć suction pipe should be 1/2" minimum or
larger if high viscosity fluids are being pumped. Suction hose must
be nonĆcollapsible type, capable of pulling a high vacuum.
SCheck all joints on intake manifolds and suction connections. These
must be airtight.
SCheck for sticking or improperly seating check valves.
SIf pump cycles at a high rate or runs erratically, check 119) piston
O" rings for wear.
