4. Troubleshooting
A) PUMP FAILS TO PRIME
1. Priming chamber empty or not sufficiently full.
2. Wrong direction of rotation.
3. Air leaks through the suction line joints (loose screws or
broken hoses).
4. Quick coupling gaskets broken or not well mounted.
5. Hose clamps loose or broken (tighten or replace).
6. Liquid in priming chamber overheated (fill with
cold liquid).
7. Delivery line under pressure (see Operating Instruc-
tions).
8. Rotation Speed too slow (increase speed).
9. Worn or broken impeller, worn or damaged volute
(replace as required).
10. Air leaks through damaged mechanical seal (replace
the seal).

B) LOW CAPACITY
1. Suction strainer clogged (clean).
2. Suction or delivery line obstructed (remove obstruction).
3. High friction losses in the suction line (eliminate
unnecessary curves, restrictions or valves).
4. Suction lift too high (set up the pump as near as possible
to the water level).
5. Rotation speed too low (increase speed).
6. Impeller clogged (remove obstruction).
