Double suction pump

　　Double suction pump

　　As an important form of centrifugal pump, double suction pump is widely used in engineering because of its high head and large flow. The impeller of this pump type is actually composed of two back-to-back impellers, and the water flowing out of the impeller flows into a volute. Double suction pump has the following characteristics: it is equivalent to two single suction impellers with the same diameter working at the same time, and the flow can be doubled under the same impeller outer diameter; The pump casing is horizontally split, which is convenient for inspection and maintenance. At the same time, the inlet and outlet of the double suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the layout and installation of the pump and inlet and outlet pipes; The impeller structure of the double suction pump is symmetrical, without axial force, and the operation is stable.

　　Structure: the suction inlet and discharge outlet of SH double suction clean water centrifugal pump are both below the axis of the pump, and the horizontal direction is vertical to the axis. The pump shell is opened in the middle. It is not necessary to disassemble the water inlet during maintenance. The discharge pipeline and motor (or other prime mover) rotate counterclockwise when viewed from the coupling to the pump. It can also be rotated clockwise according to the special order needs of users. The main parts of this type of pump are: pump body, pump cover, impeller, shaft, double suction sealing ring, shaft sleeve, bearing, etc.
