Air pressure or air volume is too
low. Increase air pressure. Check air
compressor and air supply filters
regulator, lubricator valves and
other components for blockages
and restrictions. If this is a new
system, be sure that air supply
components have been sized
properly.
The fluid valves or hoses are
closed or restricted. Check the gun, fluid hoses, mix
manifold, static mixer, fluid filters,
regulators, valves and other fluid
line components for blockages and
restrictions. If this is a new system,
be sure that the fluid components
have been sized properly.
The air motor is worn or damaged. Service the air motor. See
Disconnect the Air Motor, page 20 .
System will not run or stops while
running.
The displacement cylinder(s) is
damaged or has seized See troubleshooting techniques
below to isolate the problem
cylinder. See
Disconnect the
Displacement Pump, page 19 .
Air volume is too low.
Verify that air pressure at the air
motor inlet is not dropping during
pump changeover. Check air
compressor and air supply filters
regulator, lubricator valves and
other components for blockages
and restrictions. If this is a new
system, be sure that air supply
components have been sized
properly. 1” NPT hoses, fittings
and accessories are required to
provide the necessary air volume.
Feed pump pressure is too high. Reduce feed pump pressure.
Feed pump pressures must be
less than 25% of proportioner
output pressure.
The fluid pressure bounces
significantly (>500 psi) while pump
is running
The displacement cylinder(s)
check valves are not seating. See troubleshooting techniques
below to isolate the problem
cylinder. See
Disconnect the
Displacement Pump, page 19 .
