Design Recommendations: For Pump Stations With Vertically Installed Flygt Axial And Mixed Flow Pumps

A proper design of the pump sump is crucial in order to achieve an optimal inflow to the pumps. Important design requirements to be met are: uniform flow approach to the pumps, preventing pre-rotation under the pumps, preventing significant quantities of air from reaching the impeller, and transport of settled and floating solids. The Flygt standard pump station design can be used as is, or with appropriate variations upon review by Flygt engineers.

This document is intended to assist application engineers, designers, planners, and users of sewage and storm water systems incorporating Flygt axial and mixed flow pumps installed in a column.
