WNC Between Bearings, Diffuser Casing, Multistage, Utility Barrel Pump
The WNC is a diffuser casing, high-energy barrel pump found in power plants around the globe. Highly efficient and durable, the WNC features a massive forged barrel, tandem impellers and a cartridge-style inner casing sub-assembly.
Radially Split Inner Case Sub-Assembly facilitates inspection and maintenance in the field.
Tandem Impeller Design facilitates maintenance by permitting replacement of a single casing stage.
High-Strength Rigid Bearing Housings are incorporated into the WNC design.
High Shaft Diameter to Bearing Span Ratio results in low shaft deflection, thereby increasing bearing, mechanical seal and wear ring life.
- Flows to 1400 m3/h (6200 gpm)
- Pressures to 350 bar (5075 psi)
- Temperatures to 200°C (390°F)

|Description:||The Flowserve CHTA, with either a double suction or a single suction first stage impeller, is a double casing, multistage barrel pump. The CHTA is specifically designed and built for high temperature, high pressure and high flow applications, including boiler feedwater and water injection.|
|Description:||The CSB diffuser barrel pump has become the industry benchmark in boiler feed service. An excellent choice for both combined cycle and conventional steam cycle plants, the diffuser design of the CSB provides operational stability, hydraulic flexibility and energy efficiency in medium-and heavy-duty applications.|
|Description:||The HDB is a multistage, dual volute-type barrel pump with an axially split inner case sub-assembly. It features opposed impeller construction and incorporates a double suction first-stage impeller.|
|Description:||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.|
|Description:||The VPC vertical turbine, double casing pump is a diffuser type, single or multistage design for services with limited NPSH available.|
|Description:||The Flowserve WIK is a multistage barrel pump with a single stage, first stage impeller that is compliant with the latest API 610 (BB5) standards. The WIK is a special purpose pump designed for high-temperature, high-pressure and high-flow applications such as decoking jet, boiler feedwater and water or brine injection.|
|Description:||Rated for discharge pressures to 450 bar (6600 psi),HSO/HDO pumps are manufactured to customer specifications, often exceeding ISO 13709/API 610 (BB5). These pumps feature opposed impellers and dual volute designs, resulting in nearly balanced axial hydraulic thrust over the full operating range of the pumps. • HSO: Single suction, first stage impeller • HDO: Double suction, first stage impeller|
