Troubleshooting
Symptom
Cause
Slow Eduction Rate
Flow restrictions on outlet side of
eductor.
The eductor nozzle is plugged.
Poor Lance Suction
Granules may be too coarse.
Flow and pressure may be
too low.
Plugged Container Rinse Nozzle
Debris in the Container Rinse
system.
Leaks
Loose fittings.
Cracked fittings.
Solution
Replace 90-degree fittings with sweeping
bends using reinforced hose, especially
near the eductor outlet. Use 2" (51mm) or
larger hose and fittings all the way back to
and into the tank. If sharp bends cannot be
avoided, use oversized hose and fittings to
minimize flow restriction.
Looking down into the hopper outlet with
the hopper valve open, observe the liquid
jet should be centered and straight. If it is
off-center or if it is dispersed, flush the
system with clean water and remove the
fittings from both sides of the eductor.
Using a soft tool (wood or plastic) and
taking care to not deform the orifice, clear
the blockage by pushing it back out toward
the inlet side of the fitting. A blocked
eductor nozzle indicates that a filtration
problem elsewhere in the system must be
corrected.
Coarse product may need to be poured into
the hopper.
The lance functions best at the highest
operating pressures. See action for "Slow
Eduction Rate."
Replace nozzle and make sure there is
proper filtration in the pump system before
the Cleanload inlet.
Tighten fittings.
Replace fittings.
