<p>The present invention relates to a deep-well pump used for pumping underground water. More specifically, the purpose of the present invention is to provide the deep-well pump enabling the expectation of multiple effects such as the improvement of durability, the improvement of motor assemblability, and the reduction of production cost. Namely, the present invention includes an impeller case wherein an impeller unit is embedded and having a wire cover assembled on the outer surface in an axial direction; a discharge frame installed on the top surface of the impeller case; a suction frame installed on the underside of the impeller case; and a motor assembled in the lower side of the suction frame to operate the impeller unit. The discharge frame made of a material identical to a material of the impeller case and the impeller case are welded to be integrated. The suction frame includes a body having suction holes in all directions and an upper part screw-joined to the impeller case; a motor fixing plate joined to the lower inner part of the body by spot-welding; and a cup-shaped filter having a rim seated on a seating protrusion formed on the upper part of the body to be positioned in the lower side of the impeller unit and an arbor hole on the center.</p> |
