Regenerative Turbine Pump Design for High-Pressure, Low-Flow Systems
MTH Pumps’ product line is centered on regenerative turbine pump technology designed for applications requiring high pressure at relatively low flow rates. These pumps use multi-vane impellers that recirculate fluid within the casing, enabling them to generate higher discharge pressures than conventional centrifugal pumps at similar flow rates.
Typical operating ranges extend from fractional flow rates up to approximately 150 GPM, with pressures reaching up to 1,000 PSI, depending on the series and configuration.
In practical applications, this design is used where systems require stable flow under varying pressure conditions, including boiler feed systems, condensate handling, and closed-loop temperature control. The ability to maintain performance across pressure fluctuations is a defining characteristic of regenerative turbine pump operation.
Engineered Pump Capabilities
MTH pumps are designed to operate across a defined performance range, making them well-suited for specialized applications requiring precision and reliability.
- Pressure range: approximately 5 to 1,000 PSI
- Flow range: ½ to 150 GPM, depending on model
- Construction materials: cast iron, bronze, and stainless steel
- Configurations: horizontal and vertical, with multiple sealing and drive options
All pumps are 100% tested in an ISO-certified manufacturing facility prior to shipment to ensure performance, reliability, and consistency across applications.
This combination of performance range, material flexibility, and testing validation allows MTH pumps to support both standard and custom-engineered systems.
Regenerative Turbine, Sealless, and Centrifugal Pump Options
MTH offers a focused product portfolio designed to address specific hydraulic challenges, particularly in applications requiring high head and low flow.
Regenerative Turbine Pumps
MTH’s core product line, regenerative turbine pumps, uses a unique impeller design that recirculates fluid within the casing to generate higher pressures than standard centrifugal pumps. These pumps are available across multiple series with capacities up to approximately 160 GPM and heads exceeding 2,000 feet, depending on the model.
Sealless / Hermetic Pumps
Sealless and hermetically sealed pump designs are available for applications requiring leak-free operation. These pumps are commonly used with refrigerants and other controlled fluids, offering capacities up to approximately 45 GPM and heads up to 450 feet.
Centrifugal Pumps
MTH also manufactures close-coupled centrifugal pumps for general fluid handling applications, including washdown systems and process circulation. These pumps deliver efficient performance in low-head applications, with capacities up to approximately 110 GPM.
This combination of technologies allows MTH to support a wide range of system requirements while maintaining a focus on compact, efficient pump design.
Applications Across Industrial and Commercial Systems
MTH pumps are used in applications where pressure stability, compact design, and consistent flow are critical to system performance.
Typical applications include:
- Boiler feed and hot water systems
- HVAC and temperature control systems
- Industrial process and chemical pumping
- Commercial building systems
- Refrigeration and cooling systems
- Water, wastewater, and municipal applications
These pumps are especially effective in systems such as condensate return, pressure boosting, and heat transfer loops, where maintaining consistent pressure is essential for reliable operation.
Why MTH Pumps for High-Head, Low-Flow Applications
MTH pump designs are engineered to solve specific hydraulic challenges that standard pump technologies may not address efficiently.
Key advantages include:
