What are the differences between single-stage centrifugal pumps and multi-stage centrifugal pumps?

The single-stage centrifugal pump comprises a pump body, a pump cover, an electric motor with an output shaft, a pump shaft, a bearing seat, an impeller, a mechanical seal and a gland seal installed in the pump body, characterized in that it also comprises an electric motor output shaft A counter-jaw coupling disposed between the pump shaft and a guide bearing mounted on the bearing seat to assist the support of the pump shaft; the wafer-type coupling is rigidly connected with the output shaft of the motor and the pump shaft respectively; The distance between the output shaft of the motor and the shaft of the pump is such that the mechanical seal and the gland cover can be assembled and disassembled. It is not necessary to disassemble the motor and pump cover when servicing or replacing the mechanical seal.

The multi-stage centrifugal pump is a flowing medium (gas and liquid, but also a mixture of suspended particles and gas or liquid) entering from the root of the blade shaft (inlet), the medium relies on high-speed rotation of the blade to obtain centrifugal force, and generates a high pressure from the pressure relief port ( Outlet) Out of media delivery equipment. The multi-stage centrifugal pump integrates two or more pumps with the same function. In the fluid channel structure, the medium pressure relief port in the first stage communicates with the inlet of the second stage, and the second-stage media pressure relief port Connected with the third level of imports, such a series of institutions formed a multi-stage centrifugal pump. The significance of a multi-stage centrifugal pump is to increase the set pressure.

A single-stage centrifugal pump is a pump with only one impeller. The maximum lift is only 125 meters.

Multi-stage centrifugal pump refers to a pump with two or more impellers, the maximum head can exceed 125 meters; multi-stage pump can be equipped by increasing the number of impellers when the single-stage pump head needs to be equipped with two-stage motors. Using a four-stage motor can increase pump life and reduce unit noise, but multi-stage pump repair is a little more difficult than a single-stage pump.

When the actual pump head needs to be less than 125 meters, depending on the pump room area, the pump price (multi-stage pump is generally higher than the single-stage pump price), and other factors to consider whether the choice of single-stage pump or multi-stage pump.
