X.HT.Defender

X.HT.Defender Three-phase complete submersible pump (3x380-415V / 50 Hz)

RELIABILITY AND LONGER LIFE
 
4” complete submersible pump, made of stainless steel ZDS hydraulic part, ZDS three-phase encapsulated water-cooled HT motor, Z-Defender.3 electronic control panel and supply cable in different lenghts. Reliable, strong and easy to maintain, it's available in a wide range of models.
It can be protected against many possible installation or operation faults thanks to Z-Defender.3 electronic control panel.
 
Z-DEFENDER.3
Electronic control panel with protection and diagnostic for direct start and running of ZDS three-phase submersible pump.
  • LCD display for easy diagnostic of running parameters or eventual protections
  • Sounder alarm in the event of a fault and in stand-by
  • Low voltage input for floats or pressure switches
  • Protection against dry running and lack of water in the well
  • Current overload protection
  • Protection against low/high voltage
  • Phase sequence input control
  • Protection against failures in a three-phase plant
Z-DEFENDER.3 is an innovative electronic panel essential to start, run and protect the three-phase ZDS submersible pump against many possible installation and operation faults. Z-DEFENDER.3 is designed to guarantee an optimal protection of the submersible pump against many possible installation and operation faults: an alarm will be shown on the dispaly in case of current overload, low voltage or high voltage, dry running, phase missing or phase imbalance; ensuring a high degree of automation and restoration. Z-DEFENDER.3 allows to continuously detect and monitor in real time the power: the electrical parameters obtained are processed by a special software, which will efficiently guarantee the correct working conditions.
With Z-DEFENDER.3, the submersible pump can work and be continuously protected also when the supply voltage values are at tolerance limit, providing the effectiveness of the protection operation. In addition, Z-DEFENDER.3, thanks to a “smart software” at variable time and automatic restart, can ensure the optimization of water withdrawal from the borehole or tank when the pump is dry running. Thanks to its special and innovative ZDS technology, Z-DEFENDER.3 combines, in a single device, protection, reliability and ease of installation.

Automatic protections

Dry-running protection

Dry-running protection

The control panel automatically stops the submersible pump showing an alarm on the display, to restart it after a programmed cycle time.

Protection against low/high voltage

Protection against low/high voltage

Avoid motor damages caused by too low or too high power supply voltages.

Dry-running protection

Dry-running protection

In case the submersible pump is partially or totally blocked, after some restart attempts it enters the stand-by mode.

Phase-loss protection

Phase-loss protection

The submersible pump is protected against phase-loss (caused by a brake of a fuse). The control panel protects the motor against damaging.

Phase imbalance

Phase imbalance

Z-Defender.3 will detect any faulty electric connection, protecting the motor from potential damage.

Information on a proper installation

  • If you are using a generator with an internal combustion engine, it is necessary that the generator’ s power measured in kW (in continuous delivery) is three times the rated power in kW of the submersible pump.
  • We recommend to install a proper cooling jacket in installations bigger than 10 cm, to guarantee the correct motor cooling flow.
  • Z-Defender.3 must NOT be used with a frequency inverter.
