Problem

Which Pump Definition Types can be used by each solver?

Solution

There are many types of pump definitions in Bentley storm and sanitary sewer models. These pump definitions are established by going to Components > Pump Definitions. These definitions can be assigned to any pump element. Pump definitions contain the pump curves describing pump performance. The only curve that is mandatory for modeling a pump is the head curve. Efficiency and motor curves are only used in Bentley water models.

Some of the definitions are used only in the implicit and explicit dynamic wave solvers while others are only used in the pressure portion of the GVF-convex solver. The only definition type that is common to all solvers is the Multipoint pump head curve. The chart below shows which Pump Definition Types are available for each of the solvers.
