PURPOSE: A spiral pump is provided to pump and circulate fluid with high efficiency while reducing energy consumption by applying strong suction force at an opening section of a large wing part and reducing a size of a pump unit discharging fluid to a spiral casing. CONSTITUTION: A spiral pump includes an outer casing(1) and an inner casing(1a). A suction port(10a) is formed at a right part of the outer casing(1) and a discharge port(10b) is formed at the left part of the outer casing(1). The inner casing(1a) is installed in the outer casing(1) in such a manner that a rotating wheel(30) is rotated in the inner casing(1a). A plurality of inlet ports(30a,30b,30c) are formed in the pump rotating wheel(30) and fluid flows into the pump rotating wheel(30) through the inlet ports(30a,30b,30c). A support bearing(70a) is installed at an upper end of the outer casing(1).
