Installation Types:
WQ Submersible sewage pump can be installed through auto-coupling installation (Z), fixed base installation (P), fixed base installation (F), mobile hose installation (R) and mobile pipe installation(Y). All above-mentioned installation modes are simple, and they will be introduced respectively as below:
Automatic Coupling Installation(Z)
Fixed Installation(P)
Fix the supporting base on the foundation and connect the outlet pipe to operate.The base needs to be bolted.
Mobile Installation (R, Y)
Support the pump by its base and connect the discharge hose or pipe to run the pump. This mode is mainly used for emergency use or repair or construction. If the pipeline for mobile pipe installation has enough stiffness, it is acceptable to hang the pump by pipeline for use.
