Centrifugal pump and submersible pump features
Submersible pumps can be placed under water, centrifugal pumps on the ground, that size should be the diameter of their connection. Submersible pump is a very wide range of water treatment tools. Unlike ordinary pumps, it works underwater, while most pumps work on the ground. Submersible pump works Before the pump, the suction pipe and pump must be filled with liquid. After the pump is turned on, the impeller rotates at a high speed and the liquid rotates along with the blades. Under the action...
