circulation system.
Changing Materials
NOTICE
Changing the material types used in your equipment
requires special attention to avoid equipment damage
and downtime.
•
When changing materials, flush the equipment
multiple times to ensure it is thoroughly clean.
•
Always clean the fluid inlet strainers after flushing.
•
Check with your material manufacturer for chemi-
cal compatibility.
•
When changing between epoxies and urethanes
or polyureas, disassemble and clean all fluid com-
ponents and change hoses. Epoxies often have
amines on the B (hardener) side. Polyureas often
have amines on the B (resin) side.
