140 / 240 / 180 / 280 Turbine Pumps

140 / 280 / 180 / 280 Regenerative Turbine Pumps

MTH 140, 240, 180 & 280 Series regenerative turbine pumps represent the most economical, high performance alternative flow (to 60 GPM) applications involving moderate to high pressures (heads to 800 feet). By combining years of regenerative turbine pump designs with precision computer controlled manufacturing, the 140 / 280 / 180 / 280 line of pumps deliver high efficiency pumping operation, even at low NPSH. High quality parts and an easily serviceable design provide low maintenance and long life.

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 140 • 240 • 180 • 280 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 140 • 240 • 180 • 280 Series. The result is a high performance pump providing efficiency characteristics exceeding those of more expensive units.
