5. TROUBLESHOOTING
Fault Cause Solution
The rotor/stator pump
operates, but output is low. Pump pressure is too low,
stator is too loose. Tighten stator to achieve suitable pumping
pressure.
Pump pressure is too high,
Stator is too tight. Loosen stator to achieve suitable pumping
pressure.
Stator is worn or damaged. Tighten stator. If low output continues,
replace stator.
Rotor is worn or damaged. Tighten rotor. If low output continues,
replace rotor.
Material hose is clogged. Clean or replace the material hose.
Applicator or tip is dirty or
clogged. Clean or replace the applicator or tip.
Large pressure drop in
material hose. Reduce hose length and/or increase
diameter.
Pump does not operate. Material hose or applicator is
obstructed. Clean or replace the hose or applicator.
Dried material in pump
assembly. Clean or replace the pump assembly.
Poor finish or irregular spray
pattern. Inadequate air assist air
pressure Adjust the air assist air pressure output on
the applicator.
Pump is noisy when
pumping. Pumping water without dish
soap or a slick agent. Add dish soap or a slicking agent to the
water.
Pump is running with no
material or fluid in the hopper. Add material to hopper or shut off pump.
Erratic accelerated speed. Material supply exhausted. Refill the hopper and prime pump with
material.
Motor is powered but nothing
comes out of the hose. Pump is packed out with dry or
cured material. Disassemble and clean the pump.
Hose is packed out with dry or
cured material. Clean or replace the material hose.
Material is too thick to push
through the hose without
packing out. Hose is too restrictive. Thin the mix material thoroughly to a lower
viscosity if material supplier allows.
Use a pump system priming fluid (dish
soap or slicking agent) to wet out the
system.
Reduce length and/or increase diameter of
hose.
