Single stage split casing double suction pump

split casingpump

As an important form of centrifugal pump, double suction pump is widely used in engineering because of its high lift and large flow. The impeller of this type of pump is actually composed of two back-to-back impellers, and the water flowing out of the impeller flows into a volute. The 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 shell is horizontally opened in the middle, 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 arrangement and installation of the pump and the inlet and outlet pipes; the impeller structure of the double suction pump is symmetrical, without axial direction Force, smooth operation.
