Integrally Geared High Speed Pumps
OH6 Pumps Definition
According to API 610, Low-Flow, High-Head pumps are refered to High-speed, integral, gear-driven, single-stage overhung pumps. These pumps have a speed-increasing gearbox integral with the pump. The impeller is mounted directly to the gearbox output shaft. There is no coupling between the gearbox and pump; however, the gearbox is flexibly coupled to its driver. The pumps may be oriented vertically or horizontally. Low space occupancy and short maintenance time is some of the main advantages of this type compared to other types.
