As we all know, double suction pump is an important way of centrifugal pump, which has been widely used in engineering, thanks to its high lift and large flow. In practice, the impeller of double suction pump is composed of two back-to-back impellers. The flow from the impeller flows into a volute. Some friends will ask, "Why do double suction pumps have no axial force?" In fact, this is a decision with the characteristics of double suction pumps.
Double suction pump has three characteristics:
1. Double suction pump is equivalent to two single suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same impeller outer diameter.
2. The pump housing is open to facilitate 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 double suction pump and the inlet and outlet pipes.
3. The impeller of the double-suction pump is symmetrical in structure and has no axial force, so it runs smoothly.
