A submersible pump support including at least one pump housing, a first pump support rail extending in a first plane coupled to and supporting the at least one pump housing, a second pump support rail extending in the first direction in the first plane coupled to and supporting the at least one pump housing, wherein a distance of the at least one pump housing from the first plane is no more than one half a distance, in the first plane, between the first and second pump support rails. According to a another aspect of the invention, there is provided a submersible pump support including an intake screen located in the at least one pump housing so as to provide fluid flow over a pump assembly mounted in the at least one pump housing to an intake port of a pump in the pump assembly, the intake screen being located in the at least one pump housing and having a fluid flow capacity sufficient to provide a minimum fluid flow velocity determined by a cooling requirement of a pump assembly, the intake screen additionally having a fluid flow capacity sufficient to provide a maximum fluid flow velocity to reduce vortices in a fluid flowing through the at least one pump housing. The submersible pump support is constructed of a material having a specific gravity of less than one. In a preferred embodiment, the material is polyethylene (HDPE). |

DETAILED DESCRIPTION The disadvantages of the prior art are overcome by the present invention which provides a submersible pump support including at least one pump housing, a first pump support rail extending in a first plane coupled to and supporting the at least one pump housing, a second pump support rail extending in the first direction in the first plane coupled to and supporting the at least one pump housing, wherein a distance of the at least one pump housing from the first plane is no more than one half a distance, in the first plane, between the first and second pump support rails.
The submersible pump support is constructed of a material having a specific gravity of less than one.
In a preferred embodiment, the material is polyethylene (HDPE).
The polyethylene may include carbon black to protect the pump support from degradation due to ultraviolet rays.
According to a another aspect of the invention, there is provided a submersible pump support including at least one pump housing, a first pump support rail extending in first direction in a first plane coupled to and supporting the at least one pump housing, a second pump support rail extending in a first direction in the first plane coupled to and supporting the at least one pump housing, and an intake screen located in the at least one pump housing so as to provide fluid flow over a pump assembly mounted in the at least one pump housing to an intake port of a pump in the pump assembly, the intake screen being located in the at least one pump housing and having a fluid flow capacity sufficient to provide a minimum fluid flow velocity determined by a cooling requirement of a pump assembly, the intake screen additionally having a fluid flow capacity sufficient to provide a maximum fluid flow velocity to reduce vortices in a fluid flowing through the at least one pump housing.
A third pump support rail extending in the first direction in a second plane, coupled to and supporting the at least one pump housing, wherein the second pump support rail additionally extends in the first direction in the second plane may be added to provide a vertical submersible pump support
