Horizontal - Multistage - Double Case - WXB / WXBB
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 WXBB 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.... Read more Read less
Designed to meet the intent of API 610, latest edition the WXB pump is a BB5 category, double case horizontal, multistage, centerline mounted barrel pump.
The compact, space-saving design has a convenient cartridge-style construction to minimize maintenance down time. The WXB is field proven in oil refineries and petrochemical plants throughout the world. and first choice for most demanding applications - in all services where process conditions demand a barrel construction, process industry, refineries, chemical and petrochemical plants, liquefied gas stations, condensate service and boiler feed service.
A full range of sizes from 2” to 6” combined with a wide range of hydraulics, numbers of stages and all API material columns allows the WXB to be applied across the complete breadth of the market. An on-going research and development program guarantees an up-to-date product, constantly evolving to meet the latest standards API 682 / ISO 21049 mechanical seal chambers, ATEX, CE marking etc.
The WXBB pump is a horizontal, double case, diffuser collector, multistage, centerline mounted between bearing pump designed to meet API 610 latest edition requirements. The inner element is constructed as a two piece channel ring/diffuser stage and Barske impellers mounted in-line (tandem), utilizing a straight balance drum at the discharge side to balance residual thrust.
The hydraulics are specifically developed for low flow high head applications.
