Speeds hevo sdvonced from 1760 rpm. in 1910 to 6000 rpm. today, with shafts ranging up to 3V$* diameter. Han dling hot condensates up to 430*F. end pressures to 1250 pel. are no longer uncommon. High speed centrifugal boiler feed pumps go into service with tightning speed. Tho friction heats ordinary packing in e very short time. The oil and lubricants In theso packings are boiled out end the asbestos seises around the pump sleeves. Extensive damage ond costly shutdowns result. "JOHN CRANE" Super Seal Plotlie PockJng No. I It different* This packing has a dry flake graphite lubricant. Every asbestos fiber Is impregnated with graphite. The body of the packing is a combination of non-frictionoi metal particles. Asbestos fiber, graph- ` lie and rubber binder are semi-vuleaniied as a mass, forming a resilient. Aexiblo, non-frictionnl, strong packing. "JOHN CRANE" Super Seal Plastic Packing No. t compresses satisfactorily under gland pressuro to provide a perfect fit in the stuffing box. With proper lubrica tion, the packing runs cool and seals with minimum leakage. There is no lubrication to run out. Tho graphlto surfaces polish the sleeve. Operating engineers prefer "JOHN CRANE" Super Seal No. I for high speed centrifugal boiler *pump service. Supplied in spirals, coils and dieformed rings and sets to At ail stuffing boxes.

The power plant, rebuilt in 1920, houses one 40,000 and one 60.000 pound boiler and two 90.000 pound per hour Erie City 3-drum steam generators added in Ihe past five years. Its kwh generated has Increased from 1.8 to 34.6 million in 1951. The late G. E. Bosom, had devotod , 28 years to the careful management of this utility. Its outstanding record of rate reduction over the years is a monument to his devotion 1o the pub lic trust. It is also a manor of great prido to this community that no! ono cent of taxes was required for fi nancing tboir utility.
