Centrifugal Pump HORIZONTAL - MULTISTAGE - DOUBLE CASE - HDO AND HSO
The HDO is a between bearing, multistage, radially split double case barrel with an axially split double volute, opposed impeller inner case. Designed for medium and high pressure applications. In excess of thousands of units installed, the Flowserve HSO/HDO high pressure multistage barrel pump is a unique member of the double-case barrel pump family in that it is offered in both General Purpose and Special Purpose configurations. The HSO/HDO volute-style barrel pumps are manufactured to customer specifications, often exceeding ISO 13709/API 610 (BB5).
Pump design features two high-pressure, fully confined circular compression gasketed sealing joints to the atmosphere.
Inner case subassembly consists of hydraulically identical halves which feature dual volutes with outlets 180 degrees apart. This design assures radial balance throughout the entire operating range.
Nozzles have standard raised face flanges. Nozzle orientation can be adjusted to suit site requirements. Several nozzle configurations are available. Weld-end, ring-type joint, and tongue and groove flanges are optional.
Wrought shafts are incrementally stepped at each impeller fit for ease of assembly. The standard shaft extension is a shaft end taper.
Sleeve journal radial bearings and tilting pad thrust bearings are standard. Fan-cooled duplex ball thrust bearings are available where appropriate and permitted by ISO 13709/ API 610 (BB5).
