PROBLEM TO BE SOLVED: To mount and retain components together in a submersible pump which is inexpensive to manufacture and which has a structure facilitating the assembly. SOLUTION: This pump comprises a motor having a rotor 1 encompassed by a cooling jacket 10 and a stator 2, a driving shaft 3, a seal housing 4, a pump housing 5 having an impeller. Two groups of screw joints such as joints 15 are alternatively disposed around the pump. First group of joints 15 couples together the stator housing 8 and the seal housing 4 via a ring 13, the other group of joints couples the ring 13, the pump housing 5, the cooling jacket 10 encompassing the stator housing 8 via a ring 14. |
