Operational Recommendations

5.1 

Do not start up the equipment dry

. Vent air from the casing of the pump and the seal chamber 

before startup. Circulate clean product or a clean fluid from an external source through the seal 
chamber whenever the equipment is in operation, API Plan 11 or 32.

5.2 

If the seal runs hot, check for proper seal setting, seal housing dimensions, and check the 
bypass or flush line for obstructions. Do not allow the equipment to run for any extended  
time if the seal gets hot or squeals.

For special problems encountered during installation, contact your nearest Flowserve Sales and 
Service Representative or Authorized Distributor.
