High-speed, integral, gear-driven, single-stage overhung pumps with 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
Close-coupled, vertical, in-line, single-stage overhung pumps shall be designated pump type OH5. Close-coupled pumps have their impellers mounted directly on the driver shaft
Centreline-mounted, single-stage overhung pumps with single bearing housing to absorb all forces imposed upon the pump shaft and maintain rotor position during operation. The pumps are mounted on a base plate and are flexibly coupled to their drivers
Rigidly coupled, vertical, inline, single-stage overhung pumps with rigidly coupled shaft to the driver shaft
Foot-mounted, single-stage overhung pumps
Vertical, in-line, single-stage overhung pumps with separate bearing brackets which have a bearing housing integral with the pump to absorb all pump loads. The driver is usually mounted on a support integral to the pump. The pumps and their drivers are flexibly coupled
