ZDJet.P.Defender

ZDJet.P.Defender Single-phase complete submersible pump (1x220-230V / 50 Hz)

PROVEN PERFORMANCE AND RELIABILITY
 
4” complete submersible pump, made of technopolymer ZDS hydraulic part, ZDS 2-wire single-phase encapsulated water-cooled H2 motor, Z-Defender 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 electronic control panel.
 
Advantages:
  • Ready and easy to install
  • Doesn’ t need any further calibration or setting up
  • Integrated capacitor and special thermal protection
  • Already set for that model of submersible pump
Z-DEFENDER
Electronic control panel with protection and diagnostic for direct start and running of ZDS single-phase submersible pump.
  • Ready to use: doesn’ t need any further calibration or setting up, as it's only necessary to select the type of motor on the display
  • LCD display for easy diagnostic of running parameters or eventual protections
  • Soft start technology
  • Extra torque on start up when necessary
  • Sounder alarm in the event of a fault and in stand-by
  • When the pump is not used, even if it is in stand-by mode, weekly start-up will be commanded by the electronic, in order to avoid any blockage caused by natural sediments in the well
  • No energy consuption when in stand-by
  • Low voltage input for floats or pressure switches
Z-DEFENDER is an innovative electronic panel essential to start, run and protect the single-phase ZDS submersible pump against many possible installation and operation faults.
It's special and unique as it doesn't need any setting or self-learning, it's easy to install and ready to use, you only have to select the type of motor on the display and turn the pump on.
Z-DEFENDER 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, too frequent starts and stops and dry running; ensuring a high degree of automation and restoration.
Z-DEFENDER allows to continuously monitor the submersible pump, guaranteeing its operation in the most efficient way through a Soft start procedure (first start attempt with low starting torque) and if needed, a Strong start procedure to benefit of more starting torque.
Z-DEFENDER 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, 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, 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. Z-DEFENDER also minimizes energy consumption when the pump is not running.
Thanks to its special and innovative ZDS technology, Z-DEFENDER 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 too frequent start&stops

Protection against too frequent start&stops

In case of leaks in the piping system (also when the pressure tank is exhausted or its membrane is damaged, or when there is a defective pressure switch) and too frequent starts and stops (for example if the tank is too small for the system), the control panel automatically makes the pump enter the stand-by mode showing an alarm on the display.

Protection against low/high voltage

Protection against low/high voltage

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

Current overload protection

Current overload protection

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

Voltage peaks protection

Voltage peaks protection

Z-DEFENDER, on demand, can be equipped with internal filters designed to protect it from voltage peaks. Filters are repleaceble and of easy access. *Optional

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 must NOT be used with a frequency inverter.
  • Z-Defender is already set to work with the selected submersible pump, it doesn’t need any further calibration or setting up.
