1. Auto-coupled mounting (Z): The coupling device consists of a guide rod, a guide rod holder, an outlet pipe
0.75kw 7.5kw 11KW and above seat and a coupling frame. The pump and the pipe are connected without fasteners, making the connection
and disengagement of the pump and the pipe simple and easy; Pumps with outlet diameters can use the

same coupling device, see figure 1.

2.Fixed dry installation (G): The pump room and the sump are separate. The motor must have a cooling

system. If the pump room is flooded, it will not affect the operation of the pump. See Figure 2.

3. Fixed base installation (P): the pump is inconvenient to repair after operation, if the pipe is sufficiently rigid,

anchor bolt no need to install.see Figure 3.

4. Mobile installation (Y, R): for emergency or repair, construction needs, the base can be connected to the

hose or pipe to run, or the pump can be suspended by a sufficiently rigid drainage pipe.
