Complete List Of Flow-through Parts Of Centrifugal Pumps

Sanitary Centrifugal Pump understanding of flow-through parts

When a centrifugal pump is conveying a medium, it is generally considered that any part that the medium contacts becomes a flow-through part, including the water inlet and outlet, impeller, guide vane, shaft, bearing, pump body, seal, etc. that are in contact with the medium are collectively referred to as flow-through parts. The flow-through parts in a narrow sense refer to the rotor parts (note: rotor parts) that the medium contacts after entering from the water inlet end, mainly including: impeller, shaft, bearing, seal, etc.

What is the significance of understanding the flow-through parts of a centrifugal pump?

Whether it is the scope of flow-through parts in a broad sense or in a narrow sense, it shows that the flow-through parts in a centrifugal pump occupy the main structural position of the centrifugal pump. Different media have different requirements for materials. For this reason, separating the parts of the centrifugal pump from the flow-through parts is to reduce the waste of resources to a greater extent, reduce costs, and improve the economic benefits of the centrifugal pump. For example, if a centrifugal pump that conveys corrosive media is not classified according to the flow-through parts, the entire pump needs to be built according to the corresponding materials, which seriously wastes resources and increases production costs. However, if only the flow-through parts of the centrifugal pump are made of the material they want to use, this will achieve great cost benefits, and the operating effect of the centrifugal pump will be no different from that of the former.
