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 and are not supported with the GVF-Convex (SewerCAD) solver. The table below shows pump definition type compatibility and was last updated on 2022-Feb-25, as of CONNECT Edition update 3 (10.03.04.53):

Pump Definition Type

GVF-Convex

Implicit

Explicit

Constant Power

YES

YES

YES

Custom Extended

YES

YES

YES

Depth - Flow (Variable Speed)

NO

YES

YES

Depth vs. Flow (Type 2)

NO

YES

YES

Design Point 1 Point

YES

YES

YES

Multiple Point (Type 3)

YES

YES

YES

Standard 3 Point

YES

YES

YES

Standard Extended

YES

YES

YES

Volume vs. Flow (Type 1)

NO

YES

YES

Constant Power type, Custom Extended, Design Point 1 Point, Standard 3 Point and Standard Extended type pump data are converted into a multiple point curve of 20 points for use during calculations with the Implicit and Explicit solvers.
