TROUBLESHOOTING
The FM13V has a metering plate in the bottom of the dry
chemical hopper sized to match material flow to fluid volume
going through venturi. This plate helps each unit maintain the
approximate time required to feed 50 lb (22.7 kg) of material into
tank when engine is running at full speed. Changing material flow
rate by removing or resizing plate will affect mixing results.
Problem
Possible solutions
Slow feed rate from
hopper
Run engine at full speed
Place control valves in recommended
mixing positions.
Clear obstructions from metering plate
and check that screen is in place.
Remove build-up from venturi chamber.
Clean plugged hoses and fittings. Repair
or replace damaged hoses and fittings.
See pump instructions for procedure on
checking flow.
Poor drilling fluid
mix characteristics
Test water pH and treat if necessary (see
PREPARATION for instructions).
Clumps in drilling
fluid tank
Check feed rate.
