International brand dossier
Pentair is a broad water equipment group whose water-treatment brands include control valves, softening components, filter housings and cartridges, pumps, membrane housings, and X-Flow membrane modules.
Its influence comes from installed-base breadth: many residential, commercial, industrial, and packaged water systems are designed around Pentair components, so selection often depends on service parts, controls, and compatibility as much as on the individual product rating.
Pentair X-Flow Modules's position in ultrafiltration modules is defined by product families such as hollow-fiber, capillary, submerged, pressurized, and MBR-related UF membrane modules.The portfolio is best understood inside pretreatment, reuse, drinking water clarification, MBR solids separation, turbidity control, and pathogen barrier service, where engineers compare the technology route, family boundaries, and duty fit before narrowing to individual models.Representative series on this page include Aquaflex 20, Aquaflex 40 and Aquaflex 55.

Product range and selection
This section answers two questions: which main product families Pentair X-Flow offers, and which parameters to compare before choosing a specific model.
The main families shown on this page are General. Start with the treatment objective, equipment format, and operating duty, then use the model index below to compare exact specifications.
After choosing a product family, compare module format, flux target, backwash strategy, and chemical tolerance. Replacement projects should also verify installation or loading conditions, interfaces, and compatibility with the existing system; new projects should consider operating practice, maintenance, and spare-parts or consumables availability.
