MTH T41 E41

MTH E41 • T41 Series

Close-coupled and pedestal mounted regenerative turbine pumps represent the most economical, high performance alternative for low flow (1/2 to 22 GPM) clean fluid applications involving moderate to high pressures (heads to 600 feet).

By combining the latest concepts in hydraulic turbine pump design with precision computer controlled manufacturing, the E41/T41 Series pumps deliver high efficiency operation even at low NPSH. Costs are controlled by efficient manufacturing processes and highly optimized pump designs. Maintenance costs are kept to a minimum by combining an easily serviceable design with the use of high quality components to provide long life.

Typical Applications:
Boiler Feed Service
Condensate Return
Fuel Cells

  • Description
  • Additional information

MTH T41 E41 Design Features (Continued) IP21 enclosure and range from 1/3HP to 2HP. All D3 motors feature a 304
stainless steel shaft and CE mark approval. T41 pumps can accept most commonly available motors through the use of close or flexible coupling.
For wider fluid compatibility, T41 units 3HP and under feature a protective motor shaft sleeve, while motors 5HP and over utilize a corrosion-resistant
316 stainless steel shaft.

Steep Operating Characteristics
Near-constant capacity is maintained over wide variations in pressure. High shut-off pressure overcomes temporary line resistance.

Self-Adjusting Impeller
A hydrodynamic film on each side of the impeller positions it for long life.
The impeller exerts no thrust load on bearings. Pump operates equally well in a vertical or horizontal position.

Mechanical Seals
Bronze fitted pumps have Buna N elastomers, high temperature carbon, and ceramic seats for best hot water
service. Optional seats and materials are also available.

300# Case Working Pressure
Rigid structure is designed for maximum casing strength.

100% Tested
Every pump is fully tested to verify performance prior to shipment.

Volatile Fluid Handling
Turbine impeller handles vapors in excess of 20% by volume, minimizing the possibility of vapor locks.
”O”Ring Gaskets
“O”ring seals are used throughout the E41/T41 Series pumps to assure sealing and ease of service.
Shaft Sleeve
T41 pumps with motors 3HP and under utilize a protective shaft sleeve of an appropriate metallurgy according to the Standard Materials table.
Motors 5HP and over have a 316 stainless steel shaft with an impeller bushing as listed under Standard Materials. E41 pumps do not utilize a shaft sleeve due to the use of a standard 304 stainless steel motor shaft.

Water Flinger
A water flinger provides added protection to ball bearings in the event of seal leakage.

Simple Construction
E41/T41 Series pumps contain only three major components, allowing for easy service.

End Suction • Top Discharge
E41/T41 Series pumps fit into small spaces easily. Discharge can rotated to 90 degree, 180 degree and 270 degree positions.

Best Efficiency
New pump design optimizes efficiency for each size.

Non-Cavitating
E41/T41 series pumps may be operated under adverse inlet conditions without audible or measurable cavition.

Low NPSH
New inlet design provides superior fluid handling ability at low head inlet conditions.

Impeller

Impeller Profile One of the most notable improvements in regenerative turbine pump technology incorporated in E41/T41 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 E41/T41 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 E41/T41 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 E41/T41 Series. The result is a high performance pump providing efficiency characteristics exceeding those of more expensive units. NPSH Requirements E41/T41 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 an almost shockless fluid entry into the impeller blades and account for the high inlet efficiency in the E41/T41 Series pumps.

E41 Series

E41 Series Similar to the T31 Series, the E41 takes advantage of our custom manufactured dual face D3 motors that incorporate a 304 stainless steel shaft and heavy-duty bearing. The stainless steel shaft eliminates the necessity of a shaft sleeve, thereby reducing the parts count and simplifying maintenance and servicing procedures. All D3 motors also feature a two-pole 50//60Hz rating, as well as CE Mark approval useful for OEM’s with worldwide customers. The three-phase versions of the D3 motors feature a compact TEFC enclosure and a range from 1/3 to 3HP. The single phase D3 motors have an ODP enclosure and a range from 1/3 to 2HP. The E41 is available in horizontal close-coupled and vertical flange mounted configurations only. Please see Design Features for more detailed information on both E41 and T41 motor options.
