Water Passage Design

MTH masters one of the most critical design considerations for regenerative turbine pumps -- the shaping of water passageways to achieve highest capacity pressure while minimizing horsepower requirements. By optimizing water passageway cross-sectional profiles for each impeller, MTH improves both efficiency and pressure in the T51 Series, and exceeds standards realized by previous techniques.

Impeller Profile

One of the most notable improvements in regenerative turbine pump technology incorporated in T51 Series pumps involves the ability to determine the optimum impeller width and blade length. These factors have a significant effect on the required horsepower versus pressure curve for regenerative turbine pumps. By optimizing these for each T51 Series pump, peak efficiency is improved and "off peak" horsepower requirements are reduced as well.

Impeller Blades

After the most favorable impeller profile has been determined for a particular water passageway cross-section, MTH calculates the number of blades needed to maximize the performance of that pump. Current blade design in T51 Series pumps increases both efficiency and design pressure without the manufacturing difficulties associated with producing contoured blade impellers. State-of-the-art computer controlled machines simplify manufacturing of the various MTH impellers utilized in the T51 Series. The result is a high performance pump providing efficiency characteristics exceeding those of more expensive units.

NPSH Requirements

T51 Series regenerative turbine pumps meet low net positive suction head (NPSH) requirements without efficiency loss. This is achieved by keeping the inlet fluid velocity low and then gently accelerating to passageway velocities.
