ANSI/HI Pump Station Design

[WissamH]

Hello,

I am reading through the ANSI/HI 9.8 standard to be able to properly design a wastewater liftstation. I noticed that the standard uses D (bell outside diamter of the pump) to size the pump sump. While I know what D means when using dry wells, I am confused how to deterimine D when using submersibile pumps in wet wells.

Each of the particular submersible pump manufacturers has design parameters for the orientation of the pumps based on their design and testing.

To determine D for submersible pumps in wet wells, consider the bell outside diameter based on the pump model specifications. I guess checking the manufacturer's guidelines will clarify sizing. For more details, see this article: ANSI/HI 9.8 Standard Insights https://www.pumps.org/anis/hi

The following reference may be useful:

'Water intakes for circulating water pumps '- Pub. by BHRA(British Hydromechanics Research Association) - gives typical proportions for suction bells.

I am not familiar with any submersible pumps having bells on the intake side.
