The 3000 series of small & medium-sized pumps construction 267423
The Flygt´s 3000 Series of small and medium-sized pumps is used in a variety of applications and covers an extensive performance range. They are designed around a modular system whose drive units are the same, but whose hydraulics differ, depending on the application.

The main application area for these pumps is sewage pumping in pumping stations and treatment plants. But they also find wide use in other municipal applications, such as stormwater pumping and irrigation. Additional areas of importance include industrial applications and manure handling in agriculture.

The pumps in this series have capacities ranging from 0 to 6,000 gallons per minute.

For applications in explosive enviroments, most models can be supplied in EX-approved (explosion-proof) versions.
