Test 2
Result 2:
Material delivered at the top and bottom of the stroke is hot (curing very rapidly). Also thin areas of material
might be noticeable compared to the volume delivered in the middle of the stroke, see figure above.
Indicates: Low resin at the top (T) and bottom (B) of the pump stroke.
Probable Cause: There is no or improper accumulation effect in the resin system.
Solution: Resin accumulator full of hard material or has a blockage. Clean resin filter and
reinstall. Incorrect accumulator installed. Pump pressure is too high, lower resin pressure.
Test 3
Result 3:
Material delivered at the top and bottom of the stroke is not curing or curing more slowly than the material
delivered in the middle of the up- and down-stroke, see figure above.
Indicates: Low/no catalyst at top (T) and bottom (B) of the pump stroke.
Probable Cause: There is no or improper accumulation effect in the catalyst system. Normally
this is only a problem at high pressures.
Solution: Check to be sure you are using the proper catalyst hose, with or without core. Install a
catalyst accumulator if needed. Check for a restriction in the catalyst system.
