OH 6
High-speed integral gear-driven single-stage overhung pumps are referred to as OH 6 type 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.
