Prevent unnecessary damage to the pump. Do not allow pump to
operate when out of material for long periods of time.
Disconnect air line from pump when system sits idle for long periods of time.
GENERAL DESCRIPTION
• The diaphragm pump offer high volume delivery even at low air pressure.
• 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 check 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 pressure and will stop cycling once maximum line
pressure is reached (dispensing device closed) and will resume pumping as needed.
AIR AND LUBE REQUIREMENTS
WARNING!
injury or property damage.
• The air delivery pipe should be big enough to ensure the air needed.
• Air pressure not exceed 115 PSI (8 BAR).
• A filter capable of filtering out particles larger than 50 microns should be used on the air supply.
There is no lubrication required other than the O-ring lubricant which is applied during
assembly or repair.
• If lubricated air is present, make sure that is compatible with the O-rings in the air motor
section of the pump.
OPERATING INSTRUCTIONS
• 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.
• Disconnect the air supply from the pump if it is to be inactive for a few hours.
• Disconnect the air supply from the pump if it is not in use.
• The material supply tubing should not be too small or restrictive. Be sure not to use hose which
might collapse.
• When the diaphragm pump is used in a forced-feed (flooded inlet) situation, it is recommended
that a "Check Valve" be installed at the air inlet.
• Secure the diaphragm pump legs to a suitable surface to insure against damage by vibration.
MAINTENANCE
• Provide a clean work surface to protect sensitive internal moving parts from contamination
from dirt and foreign matter during service disassembly and reassembly.
• Keep good records of service activity and include pump in preventive maintenance program.
• Before disassembling, empty captured material in the outlet manifold by turning the pump
upside down to drain material from the pump.
TROUBLE SHOOTING
Product discharged from exhaust outlet.
• Check for diaphragm rupture
• Check tightness of diaphragm
Air bubbles in product discharge.
• Check connections of suction plumbing
• Check O-rings between intake manifold
and fluid caps
• Check tightness of diaphragm nut
EXCESSIVE AIR PRESSURE. Can cause pump damage, personal
Low output volume, erratic flow, or no flow.
• Check air supply
• Check for plugged outlet hose
• Check for kinked (restrictive) or collapsed inlet
material hose
• Check if there is leakage for the connection.
These must be air tight
• Inspect the pump for solid objects logged in
the diaphragm chamber or the seat area
