Submersible Column Pumps

In this section you'll find Flygt's offering of submersible column pumps and our conventional column pumps. All column pumps are located inside a discharge column, which is often suspended from the top structure. Submersible column pumps are seated at the bottom of the column without any fasteners or special hardware. They are quickly installed and removed for inspection and service. The traditional designs are either built as a complete unit that is installed on site, or as a pull-out type, which allows you to pull the entire rotating assembly out of the column pipe for ease of service.

Flygt's column pumps are excellent pumps for high discharge flows and low to medium discharge heads. They are the most cost effective type of pump for the flow range they can handle. The pump consists of a propeller with a fixed blade angle or a semi-axial impeller with a trim (diameter) that meets the specified duty conditions.

Column pumps are high specific speed pumps, and as such they depend on a well-designed pump sump to deliver on their factory performance. Flygt has the knowledge, tools and experience to help you design a good wet well and a practical and functional pump station.‚Äč
