Abstract

Water pumps for an urban water landscape, including a water pump main body, a water pump base, a grille net cover, and a filter component. The water pump main body includes a water pump shell. A water outlet interface is disposed on a top of the water pump shell. The grille net cover is located on a front side of the water pump shell. The grille net cover is fixedly connected to the water pump shell through a filter component pallet on a bottom of the grille net cover and filter component cross bars on two sides of the grille net cover. Two filter assemblies are inserted in series in the filter component slot. The water pump main body is detachably disposed on the water pump base.

Claims (11)
