Pump system

Abstract

The present invention relates to a pump system for delivering water from a river, a reservoir, or the like to another place. A pump system 1 according to the present invention includes a pump 5 having an impeller 16 and a drive source 17 which are disposed in a pump casing 15 , at least one pair of support pedestals 6 which are symmetrically disposed on an installation surface 2 a for the pump 5 , and a connecting mechanism 10 for connecting the pump 5 to at least one of an inlet passage 3 and an outlet passage 4 . The connecting mechanism 10 is stretchable and contractible.

1 . A pump system comprising: 
 a pump having an impeller and a drive source which are disposed in a pump casing;    at least one pair of support pedestals which are symmetrically disposed on an installation surface for said pump; and    a connecting mechanism for connecting said pump to at least one of an inlet passage and an outlet passage, said connecting mechanism being stretchable and contractible.    
   
   
       2 . A pump system according to  claim 1 , wherein said connecting mechanism comprises: 
 a pair of flange members disposed so as to face each other;    a stretchable and contractible member for connecting said flange members to each other in a liquid-tight manner; and    a relative moving mechanism for moving said flange members relative to each other so as to change a distance between said flange members.    
   
   
       3 . A pump system according to  claim 1 , wherein said drive source is a brushless synchronous motor.  
   
   
       4 . A pump system according to  claim 1 , wherein a liquid passage including said outlet passage has a siphon shape.
