The transmission assembly does not need to be directly inserted into the axis position of the shell, and there is no need to consider the installation and sealing of the transmission assembly, which can reduce the sealing requirements, thereby achieving the effect of reducing costs; it is also convenient for subsequent docking and installation with the transmission assembly of another pump body module; and it is convenient to further transfer the rotating blades by driving the small pulley to rotate through the large pulley, thereby enhancing the booster pumping effect;

The two transmission components are connected by the second pulley, so that the pump body modules can be assembled and connected by transmission. After the motor is installed, multiple pump body modules can be driven by one motor to reduce power consumption, and multiple pump body modules can form independent multi-way diversion effects. Moreover, the pump body modules can also be connected in sequence through pipelines to achieve a multi-stage pressurization effect to meet different pumping needs.
