Vertical segmented multistage centrifugal pumps are roughly divided into two structures: vertical installation of segmental multistage pumps with bottom inlet and top outlet and flat inlet and flat outlet structures. Due to the segmental structure design, the structure is relatively compact. The height of the vertical segmental multistage pump depends entirely on the number of impellers of the multistage centrifugal pump. The more stages the higher the lift, so the vertical The segmental multi-stage centrifugal pump has a relatively large head range, which is convenient for users to choose different heads. Regardless of the structure, the installation diagram of the vertical segmental multistage centrifugal pump and the required accessories are roughly the same:
One, vertical segmental multi-stage centrifugal pump installation structure diagram from bottom in and top out
The vertical segmental multistage centrifugal pump with bottom inlet and top outlet is an earlier multistage pump. Although it is gradually decreasing, it is still widely used in some occasions. The specific installation drawings and required accessories are as follows:
Figure 1. The installation preparation of the booster pump with vertical multi-stage centrifugal structure requires a little more work. Different water inlets and outlets, different heights, and bulky and bulky may cause us to spend more energy. But the existence is reasonable, the angle of the water inlet and outlet can be adjusted flexibly, which brings us great convenience in some occasions. The installation accessories are still the same: water inlet and outlet flexible soft joints (for convenience and installation), inlet and outlet valves (for debugging), inlet and outlet pressure gauges (observe the water source and outlet pressure). If it is to be automatic, a check valve and a pressure sensor must be installed in the direction of the water outlet.

Flat-in and flat-out vertical segmental multi-stage centrifugal pumps are also called vertical multi-stage pipeline pumps. They are relatively simple to install and maintain, so they are widely used in the fields of building secondary water supply equipment and industrial water supply and drainage. The installation drawing and accessories are as follows:
Figure 2. The vertical multi-stage pipeline structure booster pump is the same as the vertical single-stage pipeline booster pump to install and save effort. The advantages of the same size of water in and out, in the same straight line, and the same height from the ground as the outlet, save us a lot of time and energy. The accessories required for installation are the water inlet and outlet flexible soft joints (convenience and installation), the inlet and outlet valves (for debugging), and the inlet and outlet pressure gauges (observe the water source and outlet pressure). If it is to be automatic, a check valve and a pressure sensor must be installed in the direction of the water outlet.
