<p>A submersible sliding bearing pump comprises an impeller (7) for sucking/discharging a circulation water, a shaft (8) for fixing the impeller, a bearing (10) so secured to the impeller as to rotatably support the impeller on the shaft, a casing (9) and a separation plate (5) for containing the impeller and forming a pump chamber, a casing shaft supporter (9a) so installed at the central part of the casing as to fix one end side of the shaft (8), and a separation plate shaft supporter (5a) so installed at the central part of the separation plate as to fix the other end side of the shaft. Since the casing and the separation plate are sealed and fixed to each other by welding to form the pump chamber. A projection (9c) is formed at the bottom (9d) of the casing shaft supporter (9a).</p> |
