PURPOSE: To provide a full arc flow type pump by which external force (external pressure) applied to a motor frame outer barrel to surround a motor stator is uniformized and strain and deformation of a motor frame are prevented and which can cope with high pushing-in pressure without applying pump delivery pressure to a motor part containing a rotary body chamber and maintenance of an internal part can be performed without removing piping. CONSTITUTION: In a pump assembling body constituted so that a sucking liquid from an external part passes through a motor frame outer barrel 25 arranged in an outer peripheral part of a motor stator 28, an outer cylinder 5 forming an annular space 40 between it and an outer peripheral surface of the motor frame outer barrel 25 and the annular space 40, a pump part is arranged on the shaft end of a motor, and a delivery case 10 and delivery windows 5b and 5c to introduce a delivery liquid are arranged in an outer peripheral part of the outer cylinder 5, and a pump delivery port 10a is arranged in the delivery case 10.
