As the building site generally smaller, less displacement, drainage pump priority use of submersible sewage pump and liquid drainage pump, sewage pump generally used in important places in which liquid; vertical and horizontal sewage pump sewage pump set isolation based on self filling type absorbent, and occupied a certain space, it is less in construction use.

Drainage pump flow should be selected according to the design flow of life, when there is a displacement of water, can be selected according to the maximum flow of life. Fire elevator sump pump flow is not less than 10L/s.

The head of the drainage pump is determined according to the lifting height and pipeline loss calculation, and then a certain free head is added. Free head should adopt 0.02 ~ 0.03MPa. Drainage pump suction pipe and outlet pipe flow rate of not less than 0.7m/s, and should not be greater than 2.0m/s.

The public building should set up a spare pump for the unit in every living drainage pool. Underground room, equipment room, garage floor drain, if there are two or more than two sets of drainage pump can not pump. When the water collecting basin can not be provided with an accident drainage pipe, the water pump should have uninterrupted power supply; when the water inlet pipe can be closed, the uninterrupted power supply can not be provided, but the alarm device should be set up.

When upgrading the sewage and waste water with large impurities, the submersible sewage pump outlet pipe inside the collection tank should not be different from the merger; when upgrade their wastewater, according to the actual situation of different sets of diving pool pump discharge pipe combined discharge.
