3 Operational Recommendations
3.1 Install an adequate seal flush system. The CPM PX requires a
clean cool environment for maximum seal life. With a clean cool
product, use a bypass flush from the pump discharge (plan 11)
or a bypass flush to the pump suction (plan 13). With a clean
hot product, use a bypass flush through a cooler (plan 21) or
circulation from the seal chamber through a cooling system (plan 23).
With abrasive products or products that are incompatible with the
seal, use a flush from a clean external source (plan 32).
3.2 Remove lock outs on pump and valves.
3.3 Do not start up the equipment dry to check motor rotation, etc.
Open valves to flood pump with product fluid. Ensure that the seal
flush system is operating. Vent air from the casing of the pump and
the seal chamber before start-up.
3.4 Observe the start-up. If the seal runs hot or squeals, check the
seal flush system. Do not allow the equipment to run for any
extended time if the seal gets hot or squeals.
