Description
Burks 350CS9M Replacement Turbine Pump
The Burks 350CS9M turbine pump is a 5 HP, three-phase, 3450 RPM regenerative turbine pump used for high-head, lower-flow applications. This model is commonly ordered as a direct replacement pump for existing Burks 350CS9M installations in boiler feed, condensate return, pressure boosting, and commercial water service systems.
The 350CS9M is part of the Burks CS Series and is built with a cast iron frame, bronze impeller, and bronze raceway. If you are replacing an existing pump, verify the full model number on the nameplate, motor voltage, phase, connection sizes, and required duty point before ordering.

Why Choose the Burks 350CS9M?
- Direct replacement option for matching Burks 350CS9M pump installations
- High-head, low-flow regenerative turbine pump design
- 5 HP, 3 phase, 60 Hz motor for commercial and industrial duty
- Built with bronze hydraulic components and cast iron frame construction
- Common choice for condensate return, boiler feed, and pressure boosting systems
- Designed for applications where system head requirements exceed standard low-head pump ranges
Typical Applications
The Burks 350CS9M pump is often selected for systems that need more head pressure than a standard low-head pump can provide. Common applications include boiler feed packages, condensate handling, pressure boosting, hot water service, and other systems where a regenerative turbine pump is preferred. It is especially useful where the system calls for moderate flow with higher developed head.
350CS9M Performance Specifications
The Burks 350CS9M performance range is designed for applications requiring high head at moderate flow rates. This regenerative turbine pump delivers consistent pressure across a defined operating range, making it suitable for boiler feed systems, condensate return, and pressure boosting applications.
The 350CS9M capacity and head range should be reviewed against system requirements to ensure proper pump selection. Actual flow depends on total dynamic head. Operating outside the recommended range can impact efficiency, performance, and pump life.

350CS9M Selection Notes
The 350CS9M is typically chosen when the application needs a regenerative turbine pump that can deliver stronger head performance than smaller low-head centrifugal pumps. Before ordering, confirm motor voltage, phase, required flow range, total dynamic head, and piping connections. If you are matching an existing pump in a condensate return or boiler feed system, verify the full model number on the pump nameplate to ensure proper replacement.
Replacing an Existing Burks 350CS9M Pump
If you are replacing an existing Burks 350CS9M, match the complete model number on the pump nameplate before ordering. Confirm the motor horsepower, voltage, phase, suction size, discharge size, and required operating point. The 350CS9M is a high-head regenerative turbine pump, so it should be selected from the pump curve rather than by horsepower alone.
350CS9M vs. Other Burks CS Series Pumps
Within the Burks CS Series, the 350CS9M is a larger 5 HP model intended for applications that need a higher performance range than smaller CS pumps. If your system requires a lower flow or lower horsepower option, another CS model may be more appropriate. If your system demands the higher head and capacity range listed above, the 350CS9M is often the better fit.
