TWIN IMPELLER · HORIZONTAL
2CDX stainless-steel twin-impeller pumps
2CDX is a horizontal centrifugal range with two impellers and AISI 304 hydraulic components. Its catalogue covers pressure boosting, water supply, treatment, irrigation and air-conditioning water circuits, with the twin-impeller arrangement providing a distinct duty profile from single-stage CDX.
Range technical data
- Power range
- 0.75–3.7 kW
- Published flow interval
- 1.2–12.6 m³/h
- Published head interval
- 27–71.5 m

A closer look at the series
The 2CDX brochure identifies a twin-impeller hydraulic layout for applications that require the flow-and-head combination shown by its own curves. Pump body, impellers, diffuser and casing cover are listed in AISI 304 stainless steel, with an aluminium motor bracket and housing. Both single-phase and three-phase motor versions appear, subject to their specific protection requirements.
The publication also describes moderately aggressive liquids among general pumping uses, but suitability still depends on the actual medium and wetted materials. Compare the required operating point against the model curve, then confirm suction and discharge threads, electrical version, liquid temperature and working pressure in the relevant catalogue data.
Features
- Horizontal twin-impeller design
- AISI 304 wetted hydraulic components
- Single- and three-phase versions
- Threaded suction and discharge connections
Applications
- Pressure boosting
- Water treatment and irrigation
- Air-conditioning water circuits
Materials
Pump body, impeller, diffuser, casing cover and shaft in AISI 304; aluminium bracket and motor casing; carbon/ceramic/NBR mechanical seal.
Operating conditions
Maximum working pressure 8 bar; maximum liquid temperature 110 °C. Single-phase versions include automatic thermal overload protection; three-phase thermal protection must be provided by the user.
Construction and application
Before selecting
- Choose a 70, 120 or 200 model from the flow–head table.
- Check pressure, temperature and liquid compatibility with AISI 304 and the seal.
- Confirm inlet connection, electrical phase and required motor protection.

Series questions
What distinguishes 2CDX hydraulically from CDX?
The 2CDX brochure identifies a twin-impeller horizontal centrifugal pump. Use its own performance curves when selecting a duty point.
Does the three-phase version include thermal protection?
The brochure states that thermal protection for the three-phase version is to be provided by the user.
