description Pump CDX-L

Single 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), with hydroformed components, which ensure sturdiness, hydraulic efficiency and reliability.
The hydroforming 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. Hydroforming, which combines the power of a press with the force of water, has significant advantages over traditional

processes, namely:

  • Perfectly smooth shape
  • Highly smooth running
  • No welding points

These features ensure high corrosion resistance, high efficiency with performance above 80% and low losses.
The small size of CDX(L) electric pumps makes them suitable for 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 ν = 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.

Symbols explanation:

Q = volume flow rate
H = total head
P2 = pump power input (shaft power)
η = pump efficiency
NPSH = net positive suction head required by the pump
MEI = minimum efficiency index

The minimum efficiency index (MEI) is a measure of the quality of a pump size in respect to its mean efficiency. The minimum efficiency index is based on the hydraulic efficiency and on the head at the best efficiency point.

The efficiency of a pump with trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy consumption. The minimum efficiency index (MEI) is based on the full impeller diameter. The operation of these water pumps with variable duty points may be more efficient end economic when controlled, for example, by the use of a variable speed drive that matches the pump duty to the system
