A pump comprising an impeller chamber, an impeller attached to an adaptor shaft and being disposed in the impeller chamber. The adaptor shaft is rotatably held in an intermediate housing. A drive source is mounted on the intermediate housing. A bearing held within the intermediate housing supports the adaptor shaft in both radial and axial directions and includes socket structure directly engageable with an output shaft of the drive source. The socket structure includes clamping sections to engage with the shaft of the drive source. The shaft also includes tool engagement structure by which the shaft can be immobilized during an impeller removal procedure.
