PROBLEM TO BE SOLVED: To receive energy from air or inactive gas in a pump for pumping oil or liquid in high temperature in a metal melting furnace or a solder jet tank. SOLUTION: The pump A comprising a driving impeller 1 and a driven impeller 2 rotates the driving impeller 1 by splaying the air or the inactive gas supplied from a piping 6 to the impeller 1. The rotation of the impeller 1 is transmitted to the driven impeller 2 via a shaft 5 to rotate the driven impeller 2. Liquid in the tank 9 is pumped to a pipe 9 along with the rotation of the driven impeller 2. COPYRIGHT: (C)2006,JPO&NCIPI
