MTH T31

MTH T31 Series Pumps

The T31 Series close-coupled regenerative turbine pumps represent the most economical, high performance alternative for low flow (1/2 to 9 GPM) applications involving moderate to high pressures (heads to 400 feet). By combining the latest concepts in hydraulic turbine pump design with precision computer controlled manufacturing, the T31 Series pumps deliver high efficiency pumping operation, even at low NPSH. Maintenance costs are kept to a minimum by combining an easily serviceable design with the use of high quality components to provide long life.

Details

Water Passage Design MTH masters one of the most critical design considerations of regenerative turbine pumps – the shaping of water passageways to achieve maximum capacity and pressure while minimizing horsepower requirements. By optimizing water passageway cross-sectional profiles for each impeller, MTH improves both efficiency and pressure over the standards realized by other techniques.

Impeller Profile

One of the most notable improvements in regenerative turbine pump technology, incorporated in T31 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 parameters for each 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 the T31 Series 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 T31 Series. The result is a high performance pump providing efficiency characteristics exceeding those of much more expensive units.

Note

NPSH Requirements T31 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. Special ramps are responsible for this gentle fluid entry into the impeller blades and account for the high inlet efficiency of the T31 Series pumps. Steep Head/Capacity Curve Pumping capacity varies only slightly as pressure changes. Steep pressure characteristic overcomes temporary line resistances. Self Adjusting Impeller T31 impellers utilize balancing holes to promote hydraulic self-centering and to eliminate the need for external adjustment. The impeller exerts no thrust load on the bearings, thereby extending service life. Self-centering is equally effective whether mounted in the horizontal or vertical position. Extended Reliability Motors Custom manufactured D3 motors feature a 304 stainless steel shaft and heavy duty ball bearing for extended life. Single phase ODP and 3 phase TEFC enclosures are standard, as well as a two-pole, 50Hz/60Hz ratings, and UL and CE Marks. Capacities to 9 GPM Heads to 300 Feet Temperatures to 250°F
