TURBOFLEX FEATURES:

Turboflex regenerative turbine pumps are engineered to provide long life, low-maintenance service for low-flow application involving moderate to high pressures - such as boiler feed and similar uses. Available in single, two, three, or four stage models, Turboflex pumps offer these proven design features.

STEEP OPERATING CHARACTERISTICS -
Near-constant deliveries are maintained over wide variations in load.

NO VAPOR BINDING -
Turboflex impellers are designed to handle up to 15% vapor in the liquid being pumped.

NO METAL-TO-METAL CONTACT -
Turboflex clearances enable handling of non-lubricating fluids while maintaining adequate heads.

LOW HEAD REQUIREMENTS -
Turboflex 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 Turboflex pumps, radial load equalization is designed into the pump.

DESIGN DETAILS

STANDARD TURBOFLEX PUMPS ARE BRONZE FITTED and have hydraulically balanced impellers, 1-1/2 inch stainless steel shafts, and corrosion-resistant seals throughout.

CRANE TYPE 21 MECHANICAL SEALS incorporate EPR seals, NI-resist faces, and stainless steel components. These advanced seals permit elevated-temperature operation even with aggressive fluids.

LIP-SEALED #207 BALL BEARINGS, on both inboard and outboard ends, operate within rugged cast-iron bearing supports, 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.
