The CHTA is a high capacity boiler feed pump for supercritical and ultra supercritical power stations. Heavy-Duty, Between Bearing, Multistage, Double Case Barrel Pump.

The CSB is a cost-effective, diffuser-style barrel pump for boiler feed service in combined cycle and start up service in thermal power plants. Multistage, horizontal barrel, diffuser design. Axial thrust balance device with stacked rotor construction.

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).

The WCC is a between bearing, multistage, double case, diffuser style barrel pump designed for medium duty applications in the oil & gas, chemical process industry and general industry markets. With numerous units installed, the Flowserve WCC(D) medium duty multistage barrel pump is a unique member of the double-case barrel pump family. The operating window is set out for the standard product range; however Flowserve has numerous installations in excess of this range what would be considered as fully engineered hydraulics and pump package.

The WIK(O) is a between bearing multistage, double-case, diffuser style barrel pump designed for un-spared service, critical high-pressure and high-temperature process and industrial applications.

The WXB is a multistage, diffuser-casing barrel pump with tandem impellers and a balance drum to carry axial thrust forces. It is designed for users who need the hydraulic range and performance of a ring section pump, but demand the design and maintenance attributes of a barrel pump. An extension of the well-proven WXB, the WXB-B is an API 610-style, multistage barrel pump which incorporates Barske style impellers to produce stable low-flow performance. It is a reliable, direct drive solution for low-flow, high-head applications.
