3 Operational Recommendations

3.1 Install an adequate seal flush system. The 84/85 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 clean hot product, use a

bypass flush through a cooler (plan 21). With abrasive products or

products that are incompatible with the seal, use a flush from a

clean external source (plan 32).

Note: All piping plan designations used in these instructions are from

API 682. For the corresponding ASME B73 piping plan designation,

please add a 73 in front of the referenced piping plan.

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.

4 Operational Recommendations

4.1 Do not exceed corrosion limits. The 84/85 seal is designed

to resist corrosion by most chemicals. However, do not expose

the 84/85 materials of construction to products outside of their

corrosion limits.

4.2 Do not exceed the Pressure limits of the 84/85 seal, contact your

nearest Flowserve Sales and Service Representative or Authorized

Distributor.

4.3 Do not exceed the temperature limits of the 84/85 seal. The

materials of construction are listed on the box label. Turn on

cooling water to the supply tank before start up if the tank has coils.

For special problems encountered during installation, contact your

nearest Flowserve Sales and Service Representative or Authorized

Distributor.
