MTH Pumps T51J-AB LE 56C AB Regenerative Turbine Pump
The MTH Pumps T51J-AB LE 56C AB is a high-performance regenerative turbine pump engineered for demanding applications requiring high pressure at relatively low flow rates. Built with all-bronze construction, including a precision-machined impeller and internal components, this pump delivers exceptional corrosion resistance and long service life in both industrial and marine-adjacent environments. Its compact, close-coupled design with a 56C motor frame ensures easy installation while maintaining robust performance.
Designed for efficiency and reliability, the T51J-AB utilizes advanced regenerative turbine technology to achieve heads up to 700 feet with smooth, stable operation-even under low NPSH conditions. The hydraulically balanced impeller and optimized internal water passages reduce cavitation and improve energy efficiency, making it ideal for continuous-duty applications involving clean liquids.
Whether used in water circulation systems, washdown operations, or light chemical transfer, this pump offers dependable performance with minimal maintenance. Its Buna mechanical seal, stainless steel shaft, and heavy-duty bearings provide leak-free operation and extended durability in demanding environments.
