3. Obstruction in the pump, which can be determined by a drop in pressure. If the drop in pressure
is accompanied by a frothy or whitish discharge stream, the blockage is in the suction line or
sump area. To clear the pump:
A. Disengage (turn off) the slurry pump clutch and stop the engine.
B. Loosen the suction pipe clamps. If there is material in the tank, shut off the suction line
valve.
C. Remove the clamp closest to the pump.
NOTE: If no water comes out, obstruction is in sump area.
E. Reach into the pump and remove the obstruction. If jammed, the pump suction cover
may need to be removed.
F. Reassemble all removed components.
G. Open suction line valve.
4. Obstruction in sump area, which is located at the bottom of the tank on the inside where
the suction pipe is attached.
Three methods to remove an obstruction in the sump area are as follows:
A. Clear the sump by backflushing through the discharge plumbing with the water supply
hose.
B. Remove the drain plug and run a long pole through the opening and into the sump area.
Remove the obstruction and replace the drain cap.
C. Use a pipe or pole through the loading hatch opening to dislodge the obstruction.
Do not turn the pump shaft backward with a pipe wrench. This will
unscrew pump impeller from pump shaft. Consequently, when the slurry
pump clutch is engaged (turned on), the pump impeller will screw onto pump shaft with a force
great enough to break pump impeller. Failure to comply could result in minor or moderate
personal injury. Failure to comply could also result in product or property damage.
