S Consult local building codes and electrical codes for specific
grounding requirements.
S After 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.
S Submerse the outlet hose end, dispensing valve or device in
the material being dispensed if possible. (Avoid free streaming
of material being dispensed.)

GENERAL DESCRIPTION
OPERATING INSTRUCTIONS
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
S Use 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.
S If lubricated air is present, make sure that it is compatible with the
Nitrile O" rings in the air motor section of the pump.
S Always 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.
S Disconnect the air supply from the pump if it is to be inactive for a few
hours.
S The 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.
S When the diaphragm pump is used in a forcedĆfeed (flooded inlet)
situation, it is recommended that a Check Valve" be installed at the
air inlet.
S Secure the diaphragm pump legs to a suitable surface to insure
against damage by vibration.
MAINTENANCE
S Provide a clean work surface to protect sensitive internal moving
parts from contamination from dirt and foreign matter during service
disassembly and reassembly.
S Keep good records of service activity and include pump in prevenĆ
tive maintenance program.
S Service 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.
S Check for diaphragm rupture.
S Check tightness of (6) diaphragm nut or (14) bolt.
Air Bubbles in product discharge.
S Check connections of suction plumbing.
S Check band clamps on intake manifold (nonĆmetallic models).
S Check O" rings between intake manifold and fluid caps.
S Check tightness of (6) diaphragm nut or (14) bolt.
Pump blows air out main exhaust when stalled on either stroke.
S Check U" cups on (111) spool in major valve.
S Check (141) valve plate and (140) insert for wear.
S Check (103) sleeve and (2) O" ring on diaphragm connecting rod.
S Check (119) O" rings on (118) pilot rod for wear.

Low output volume.
S Check air supply.
S Check for plugged outlet hose.
S For the pump to prime itself, it must be mounted in the vertical posiĆ
tion so that the balls will check by gravity.
S Check 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.
S Check all joints on intake manifolds and suction connections. These
must be airtight.
S Check for sticking or improperly seating check valves.
S If pump cycles at a high rate or runs erratically, check (119) piston
O" rings for wear.
