Pump Specifications

Pump specifications depend upon numerous factors but mostly on application. Typically, the following factors should be considered while preparing a specification.

1. Application, scope, and type
   
2. Service conditions
   
3. Operating conditions
   
4. Construction application-specific details and special considerations
   
   • Casing and connections
     
   • Impeller details
     
   • Shaft
     
   • Stuffing box details—lubrications, sealing, etc.
     
   • Bearing frame and bearings
     
   • Baseplate and couplings
     
   • Materials
     
   • Special operating conditions and miscellaneous items

Table below is based on the API and ASME codes and illustrates a typical specification for centrifugal pumps.
