Design Features

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
