PURPOSE: To provide a barrel casing type turbine pump where noise can be reduced at a specific rotating speed. ;CONSTITUTION: A water extracting chamber 9 and a discharging chamber 10 are divided via a vibration insulating member 11 interposed between an outer casing 1 and an inner casing 5. The vibration insulating member 11 is brought into contact with the outer casing 1 and the inner casing 5 due to a fluid pressure to be exerted on the inner casing 5, to thus seal the outer casing 1 and the inner casing 5 and insulate vibration to be propagated from the inner casing 5 to the outer casing 1.;COPYRIGHT: (C)1995,JPO
