Multistage Regenerative Turbine Pumps

nnnn

• Capacities to 40 GPM

nnnn

• Heads to 2300 Feet

nnnn

• Single or Multi-stage Units (up to 5 stages)

nnnn

• Vertical Close Coupled

nnnn

nnnn

Vertical base mount and horizontal

nnnn

pedestal mounted multi-stage

nnnn

regenerative turbine pumps

nnnn

represent the most economical high

nnnn

performance alternative for low flow

nnnn

(2 to 38 GPM) applications involving

nnnn

moderate to high pressures (heads to

nnnn

2300 feet).

nnnn

By combining the latest concepts

nnnn

in hydraulic turbine pump design

nnnn

with precision computer controlled

nnnn

manufacturing, M50 Series pumps

nnnn

deliver high efficiency operation

nnnn

even at low NPSH. Costs are

nnnn

controlled by efficient manufacturing

nnnn

processes, use of standard motors,

nnnn

and highly optimized pump designs.

nnnn

Maintenance costs are kept to a

nnnn

minimum by combining an easily

nnnn

serviceable design with the use of

nnnn

high quality components to provide

nnnn

long life.

nnnn

Water Passage Design

nnnn

MTH masters one of the most critical

nnnn

design considerations of regenerative

nnnn

turbine pumps - the shaping of

nnnn

water passageways to achieve

nnnn

maximum capacity and pressure

nnnn

while minimizing horsepower

nnnn

requirements. By optimizing water

nnnn

passageway cross-sectional profiles

nnnn

for each impeller, MTH improves both

nnnn

efficiency and pressure in the M50

nnnn

Series, and exceeds the standards

nnnn

realized by previous techniques.

nnnn

Impeller Profile

nnnn

One of the most notable

nnnn

improvements in regenerative turbine

nnnn

pump technology, incorporated in

nnnn

M50 Series pumps, involves the

nnnn

ability to determine the optimum

nnnn

impeller width and blade length.

nnnn

These factors have a significant

nnnn

effect on the required horsepower

nnnn

versus pressure curve for

nnnn

regenerative turbine pumps. By

nnnn

optimizing these for each pump,

nnnn

peak efficiency is improved and "off

nnnn

peak" horsepower requirements are

nnnn

reduced as well.

nnnn

Impeller Blades

nnnn

After the most favorable impeller

nnnn

profile has been determined for a

nnnn

particular water passageway cross-

nnnn

section, MTH calculates the number

nnnn

of blades needed to maximize the

nnnn

performance of that pump. The

nnnn

blade design in M50 Series pumps

nnnn

increases both efficiency and design

nnnn

pressure without incurring the

nnnn

manufacturing difficulties associated

nnnn

with producing contoured blade

nnnn

impellers. State-of-the-art computer

nnnn

controlled machines simplify

nnnn

manufacturing of the various MTH

nnnn

impellers utilized in the M50 Series.

nnnn

The result is a high performance

nnnn

pump providing efficiency

nnnn

characteristics exceeding those of

nnnn

much more expensive units.

nnnn

NPSH Requirements

nnnn

M50 Series regenerative turbine

nnnn

pumps meet low net positive suction

nnnn

head (NPSH) requirements without

nnnn

efficiency loss. This is achieved

nnnn

by keeping the inlet fluid velocity

nnnn

low and then gently accelerating

nnnn

to passageway velocities. Special

nnnn

ramps are responsible for this

nnnn

gentle fluid entry into the impeller

nnnn

blades and account for the high inlet

nnnn

efficiency of the M50 Series pumps.
