Material imbalance

Inadequate flow from pump; cavitation Increase fluid supply to proportioning pump

Worn pump inlet valve ball/seat or gasket, repair as
necessary

Erratic pump movement

Pump cavitation

Feed pump pressure is too low, adjust pressure to
within required range

Pump output low

Obstructed fluid hose or mixer; fluid
hose ID too small

Open, clear; use hose with larger ID

Worn piston valve or intake valve in
displacement pump

See pump manual for appropriate repair procedure

Inadequate feed pump pressure

Check feed pump pressure and adjust to within
required range
