S Serie

Categories: ,


The Constructive Series S 4 “, are multicellular submerged centrifugal electric well pumps for domestic, industrial, irrigation and pressurized water installations by means of hydraulic accumulators.

  • They are designed for the extraction of water from deep wells and reduced drilling diameter.
  • Its modular composition is formed by the hydraulic pump, and the submersible electric motor, which is coupled to the bottom of the pump.
  • They can work vertically or horizontally (with cooling bell).
  • The pump is supported by normal trade pipe sections that expel the water to the outside.
  • Power ratings range from 0.5 to 10 hp in three-phase to 220, 380, 400, 415 volts and from 0.5 to 3 hp in single-phase.
  • Pumps cannot run dry.
  • Maximum liquid temperature 30º.
  • Maximum sand 200 gr/m3.
  • Built-in check valve.

Some of its advantages are :

  • It is not necessary to dismantle the strainer to pass the cable.
  • High corrosion resistance of the entire pump.
  • Good hydraulic performance, higher yields
  • Its configuration allows to increase/decrease the pressure, adding or eliminating phases.
  • Eliminates priming complications, pump always in charge (submerged)
  • Eliminates problems in aspiration
  • Avoids air intakes
  • No pump-motor alignment problems
  • Less noise pollution
  • Cost reduction, minimum maintenance.
  • No need for a bench, reduced installation space
  • Less civil works
  • Longer service life

The installations of the series consist of three parts

1- Hydraulic body

  • The hydraulic body is made up of a suction body, a discharge body, and stages or phases, made up of closed multi-channel radial type diffuser and impeller bodies.
  • The different stages are cased in a stainless steel casing that guarantees a high resistance to the whole pump and avoids possible deformations.
  • The diameter of the group is 4″.
  • The set of impellers driven by the central shaft that transmits the power of the motor.

2- Submersible electric motor

  • Electric submersible motor of 50 or 60 Hz with IP-68 protection that supports the axial thrust of the pump, by means of a widely dimensioned axial bearing.
  • The stator winding is flooded in oil or water, the bearings are lubricated by the internal liquid, and require no maintenance.
  • These engines are manufactured by the most prestigious specialized firms.
  • The coupling flanges are designed in accordance with NEMA standards, simplifying maintenance and repair operations.

3- Hydraulic column

  • The hydraulic column is made up of sections or stages of normal commercial piping, depending on the depth of the well.


S 4″ Series pumps are suitable for:

  • Water supply and distribution.
  • Overpressure systems
  • Irrigation and sprinkler systems
  • Cooling towers
  • Chemical industries
  • Sanitary and cleaning facilities.
  • Industry in general
  • Ornamental fountains
  • Air Conditioning Installations
  • Washing systems
  • Fire-fighting installations
