description Pump 2cdx (l)
Twin impeller centrifugal pump with hydraulics in AISI 304 and AISI 316 stainless steel, with radial impeller, with hydraulics entirely in pressed AISI 304 or AISI 316 (L version).
The double impeller makes for a wider performance range than the single-impeller version.
The components of the 2CDX(L) electric pump are obtained through the renowned hydroforming process, which guarantees sturdiness, hydraulic efficiency and reliability.
The process uses a high-pressure fluid (up to 1200 bar) to form the metal.
The hydraulic fluid, in our case water, with increasing pressure pushes the stainless steel to copy the shapes of the template until it comes into contact with the internal walls of the matrix that forms the mould.
This exclusive system, which combines the power of a press with the force of water, has significant advantages over traditional processes:
- Perfectly smooth shape
- Highly smooth running
- No welding points
These features ensure high corrosion resistance, high efficiency with performance of over 80% and low leakage.
2CDX(L) electric pumps, thanks to their small size, can be positioned even in narrow or difficult to reach spaces.
The versatility of these electric pumps is due to the different types of mechanical seals that can be applied.For further technical information see the Databook

PERFORMANCE CURVE SPECIFICATIONS
The specifications below qualify the curves shown on the following pages.
Tolerances according to ISO 9906:2012 – Grade 3B
The curves refer to effective speed of asynchronous motors at 50 Hz, 2 poles.
Measurements were carried out with clean water at 20°C of temperature and with a kinematic viscosity of = 1 mm2/s (1 cSt)
The NPSH curve is an average curve obtained in the same conditions of performance curves.
The continuous curves indicate the recommended working range. The dotted curve is only a guide.
In order to avoid the risk of over-heating, the pumps should not be used at a flow rate below 10% of best efficiency point.
