Flowserve - High Pressure Between Bearings Pump (WXH)

The High Pressure Between Bearings Pump (WXH) is a utility-grade, horizontal, multistage, single case pump engineered for demanding applications such as boiler feed and thermal cycle auxiliary (TCA) duties in combined cycle and solar power plants. Its robust, segmental ring diffuser design ensures precise hydraulic performance and enhanced reliability, while the radially split pressure casings maintain concentricity and rotor alignment. The pump features an axial thrust balance device with stacked rotor construction, heavy-duty rotor with short bearing spans for minimized deflection, and precision-cast diffusers to equalize radial loads. These attributes contribute to extended service life, reduced maintenance, and adaptability to changing operating conditions. Commonly used in power generation, oil and gas, downstream processing, and general industrial sectors.
