The vertical multistage centrifugal pump should be selected according to the liquid to be transported, and the required performance should be checked, and the suction and discharge conditions should be analyzed, whether it is intermittent operation or continuous operation, etc. Centrifugal pumps should generally be operated at or near the pressure and flow conditions specified by the manufacturer's design. The following review should be carried out during installation:

1. The size, position and elevation of the vertical multistage centrifugal pump foundation should meet the design requirements, the anchor bolts must be properly and correctly fixed in the concrete foundation, and the machine should not have missing parts, damage or corrosion;
2. According to the characteristics of the medium conveyed by the centrifugal pump, the material of the main parts, shaft seals and gaskets should be checked if necessary;
3. The leveling and alignment of vertical multistage centrifugal pump equipment shall comply with the provisions of the equipment technical documents, if there is no provision, it shall comply with the provisions of the current national standard "General Specifications for Construction and Acceptance of Mechanical Equipment Installation Engineering";
4. All the pipes connected to the pump body of the centrifugal pump, the installation of pipe fittings and the cleaning requirements of lubricating oil pipes shall comply with the relevant national standards.
The above is the introduction to the selection and installation of vertical multistage centrifugal pump.
