3 Type 21 and Type 31 Operational Recommendations
3.1 Remove lock outs on equipment and valves.
3.2 Do not start up the pump dry to check motor rotation or for any other
reason. Open valves to flood pump with product fluid. Vent air from
the casing of the pump and the seal chamber before start-up.
3.3 Observe the start-up. If the seal runs hot or squeals do not allow the
pump to run for any extended time.
3.4 The seal is designed to resist corrosion through proper material
selection. Do not expose the seal materials of construction to
products outside of their corrosion limits. Consult Flowserve for
chemical resistance recommendations.
3.5 Do not exceed pressure and speed limits established for the seal.
3.6 Do not exceed the temperature limits of the seal based on the
materials of construction.
