How should you compare CDL and CDLF pumps?
Start with the required flow and head at the same operating condition. CDL and CDLF are vertical multistage series; the liquid, wetted materials, seal and installation dimensions determine which proposed configuration deserves further review.
| 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. |
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.
Prepare a comparison you can use
- CDL vs CDLF: what to confirm — compare materials, seals and the proposed duty on the same basis.
- Pump RFQ checklist — collect the technical and order information needed for a useful quotation.
- Pump purchasing FAQ — review model selection, documents, samples and order questions.
Questions before model selection
Does CDLF automatically suit every corrosive liquid?
No. Suitability depends on the liquid composition, concentration, temperature and the actual wetted materials and seal. Ask for the material configuration of the proposed model before deciding.
Can I choose a multistage pump from the required pressure alone?
Pressure or head must be considered together with the required flow and inlet conditions. Send these values with units, along with the liquid, temperature and electrical supply, so the offered duty curve can be reviewed.
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.
