N e w X-FLO Turbo Compressor Represents Major Advance In Impeller Technology

—Literature Available Ingersoll-Rand Company, Charlotte, N.C., recently introduced the new X-FLO compressor that is said to represent a major advancement in impeller technology.

X-FLO's impeller design makes high-speed rotation possible, without the bending stress usually associated with conventional centrifugal compressors. Due to the impeller's 45 exit angles, air flows in a smooth curving direction with decreased loss.

Because the impeller is 30-40 percent smaller in diameter than typical centrifugal impellers, X-FLO is easier to install and more economical to operate and maintain. The X-FLO Air/Gas configuration's performance specifications include 2,000-175,000 cfm, Adiabatic heads to 31,000 feet, and pressures to 22 psi.

The standard construction material is cast iron, and a variety of seals are available for different gas applications. The X-FLO Air/Gas can be ordered in a variety of alternative materials, with cast steel or cast stainless steel volutes, cast steel gear case, and stainless steel or titanium impellers.

X-FLO has few moving parts, providing maintenance- free operation for extended periods of time and substantial energy savings. All models feature stainless steel inlet guide vanes as standard and utilize an easy access horizontally split gearcase for inspection or repair. Bearings are journal type throughout and can be either 3-lobe or tilting pad, depending on the application.

Gearing is AGMA Class 12 or better.

Oil is provided by a shaft-driven main oil pump with an electric prelube pump. The shaftdriven lube pump runs at bull gear speed, providing continuous lubrication during operation.

The main oil pump continues to provide lubrication in the event of power failures and coastdowns.

The X-FLO can also comply with API requirements for chemical and refinery applications.

Industries and applications particularly suited for the X-FLO include utility, chemical/ petrochemical and refining, large municipal wastewater treatment plants, food processing, mineral processing, pharmaceuticals, and pulp and paper industries.
