| MTH 150 • 250 • 160 • 260 •
170 • 270 Series regenerative turbine pumps are engineered
to provide long life, low-maintenance service for low-flow applications
involving moderate to high pressures -- such as boiler feed and
similar uses. Available in single, two, three, or four stage models,
MTH pumps offer these proven design features...
Steep Operating Characteristics
Near-constant capacity is maintained over wide variations in pressure.
High shut-off pressure overcomes temporary line resistance.
No Vapor Binding
MTH impellers are designed to handle up to 20% vapor in the liquid
being pumped.
No Metal to Metal Contact
MTH clearances enable handling of non-lubricating fluids while
maintaining adequate heads.
Low Head Requirements
MTH pumps have excellent NPSH characteristics, which makes them
ideally suited for difficult applications.
Minimum Shaft Deflection
provided by heavy-duty outboard bearing supports on both sides
of the impeller.

Balanced Radial Loads
On multi-stage MTH pumps, radial load equalization is designed
into the pump.
Standard Pumps
Are Bronze Fitted and have hydraulically balanced impellers, one-inch
stainless steel shafts, and corrosion-resistant seals throughout.
Mechanical Seals
incorporate EPR seals, ceramic or Ni-resist faces, and stainless
steel components. These advanced seals permit elevated-temperature
operation even with aggressive fluids.
Lip-Sealed #204 Ball Bearings
on both inboard and outboard ends, operate within rugged cast-iron
bearing supports and are permanently lubricated for maintenance-free
long life.
Replaceable Channel Rings
of 30,000 PSI cast iron, and Buna “O”rings at all
sealing points, contribute to trouble-free operation
