Clean-Water, Split-Case & Mixed-Flow Pumps
Compare FOBENG clean-water, hot-water, split-case double-suction and mixed-flow pump series. Confirm the flow and head, liquid temperature, inlet conditions, installation arrangement, materials, pipe interfaces and electrical supply before model selection.

Which pump family should you start with?
Use the liquid and application to identify a starting family, then confirm an actual model at the required flow and head. A series name describes a product route; the final duty curve, materials, electrical supply and installation still need to match your project.
| Series | Starting application or arrangement | Confirm before choosing a model |
|---|---|---|
| CDL | Vertical multistage configuration for clean, non-corrosive liquids; explore building water supply, pressure boosting and water treatment. | Operating-point curve, actual wetted materials and seal, available inlet condition, motor supply and dimensions. |
| CDLF | Stainless steel vertical multistage series for water supply, industrial pressure boosting and water treatment. | Liquid composition and temperature, the stainless steel grade for each relevant part, seal compatibility and the offered model. |
| ISG | Vertical inline centrifugal arrangement for suitable clean-water supply, pressure boosting and HVAC circulation duties. | Flow/head match, flange arrangement, installation height, service clearance and power supply. |
| ISW | Horizontal centrifugal arrangement for suitable clean-water supply, irrigation and circulation duties. | Inlet and discharge orientation, base and connection dimensions, inlet conditions and duty curve. |
| ZW | Self-priming sewage series for wastewater containing suspended solids or fibrous matter. | Solids and fibre characteristics, liquid temperature and density, suction layout and the selected model's priming conditions. |
Connect the series to your application
- Building water pressure boosting: define demand, inlet pressure and the required outlet condition.
- Water treatment and filtration: identify the process stage and liquid composition.
- HVAC and chilled-water circulation: review the circulation duty and piping layout.
- Sewage transfer with the ZW series: describe the wastewater and suction arrangement.

Questions before model selection
What information should I send if I do not know the pump model?
Describe the application and liquid, required flow and head with units, liquid temperature, inlet conditions, installation space, voltage, phase and frequency. Include quantity and destination when requesting a quotation.
Where should I confirm the performance curve and installation dimensions?
Request the curve and drawing for the actual model being proposed. The series pages provide an introduction; model-specific flow, head, motor power, connection sizes and dimensions are confirmed during selection and quotation.
Have a duty point or an existing pump to review?
Send the operating requirement, or the nameplate and installation details with the conditions you need to achieve.
