PUMPS
 
     
 
SUMMARY
 
     
          All pumps are considered under the systems which they serve.  As for those few pumps which are specified by the Navy Filing Manual as being treated separately under the heading, the following is the situation.  
          a)  Fire pumps - there are no such pumps, the fire main being served by one of the auxiliary drain pumps.  
          b)  Fresh Water Pumps - these are small oscillating force pumps, hand operated, of no exploitational interest, and have been considered under the description of the fresh water system.
