Burks CS Series Regenerative Turbine Pumps

High Pressure Performance for Low-Flow Applications

The Burks CS Series regenerative turbine pumps are engineered for applications requiring high pressure at relatively low flow rates. Designed to handle clean water and other non-abrasive, low-viscosity liquids, these pumps provide exceptional pressure generation in a compact, close-coupled package, making them ideal for boiler feed, condensate return, pressure boosting, heat transfer systems, and industrial process applications.

Unlike conventional centrifugal pumps, the CS Series utilizes regenerative turbine technology to produce significantly higher discharge pressures while maintaining smooth, reliable operation. This makes the series an excellent solution when high head performance is required without the need for larger multistage pump systems.
