New Terry Turbine Offers Low-Cost Maintenance

—Literature Available Terry Steam Turbine has announced a new single-stage turbine for applications up to 50 hp, incorporating a unique "back-pullout" feature which assures minimal maintenance expense, according to William L. Wathen, Terry president.

Called GLT-260, the small turbine meets the longevity requirements of API 611, and includes Terry's unique rotating parts assembly design, affording the proven maintenance simplicity of back pullout pumps. "This provides remarkable convenience, and maintenance time savings," Mr. Wathen said.

Other GLT-260 features include: Terry's proven cantilevered, solidwheel design; oil-free lubricating system; innovative governor valve, and tight shut-off trip valve; component standardization; steel casing, and stainless steel glands.

With one packing box, GLT-260's gland maintenance costs are cut in half. Also corrosion and erosion problems—common in iron or carbon steel gland boxes—are minimized with use of stainless steel.

The unit's high temperature ball bearings are sealed and greasepacked, eliminating the need for lube oil, related maintenance costs, and cooling water. Bearing life is L- 10, in excess of 50,000 hours.

Standard governor provided with the GLT-260 is a Woodward TG-13.

"Its high-level performance and excellent maintenance record help assure long, trouble-free service," Mr.

Wathen commented.

GLT-260 turbines are available in inlet pressures and temperature ratings to 650 psig (45.7KG/CM2) and 750F (399C), and back pressures to 75 psig (5.3 KG/CM2).

Terry Steam Turbine, headquartered in Windsor, Conn., is a component of Ingersoll Rand Worldwide, with other manufacturing facilities in Niantic, Conn.; Germany; Mexico; and Canada.
