Typical Applications
A 2500 HP speed increaser with a 1:5.897 ratio and a 1.8 service factor is a highly specialized piece of power transmission equipment. Typical applications include:
•Centrifugal Compressors: Stepping up a standard 1785 RPM electric motor to the 10,000+ RPM required by large multi-stage centrifugal gas compressors.
•High-Speed Pumps: Driving high-pressure boiler feed pumps or specialized process pumps.
•Power Generation: Used in reverse as a speed reducer for turbine-driven generator sets.
This is a critical drop-in replacement for facilities running similar high-speed rotating trains.
