Multi stage centrifugal pump according to the installation structure can be divided into horizontal multi-stage centrifugal pump and vertical multi-stage centrifugal pump
1. Inlet and outlet of the multistage centrifugal pump has the same size and they line in the same center line, which can be installed in pipe as the valve. There are some advantages, such as the compact appearance, small footprint, low construction investment and it can be used in outdoor after equipped with protective cover.
2. Impeller mounted directly on the extension of the motor shaft, short axial size, compact structure, reasonable configuration between pump and motor bearings, can effectively balance the pump functioning of the radial and axial load, so as to ensure the smooth operation of the pump, small vibration, low noise.
3. Seal with mechanical seal or mechanical seal combination of imported titanium alloy sealing ring, medium and high temperature mechanical seal with carbide materials, wear-resistant sealing, can effectively prolong the service life of mechanical seal.
4. Easy installation and maintenance, which no need to remove the road system, as long as the pump body can be removed from the pump body parts.
5. Decide the connection type according to the requirements of the flow and head
6. According to the requirements of piping layout, we can choose the type of pump installation.
Horizontal multistage centrifugal pump has stable operation and long service life. Inlet and outlet can be installed into 90 degrees.
1. Different appearance, the vertical pump is standing and horizontal pump is lying.
2. Different forms of connection, vertical pump from bottom to top, horizontal pump vertical arrangement in the base.
3. Different installation requirements, the vertical pump occupies a small area and the horizontal pump occupies a large area.
4. Different maintenance, vertical pump is difficult to maintenance, it may be required to remove all the upper impeller rear, but horizontal pump just need to remove the impeller what you want to repair
5. Different forms of installation, vertical pump for the overall connection, installation is easy; and the horizontal pump installation after the need for precision adjustment.
