QPGo.P.DRP-Plus

QPGo.P.DRP-Plus Single-phase complete submersible pump (1x220-230V / 50 Hz)

THE BEST QUALITY/PRICE 4" SUBMERSIBLE PUMP
 
4" complete submersible pump, made of ZDS hydraulic part in technopolymer, ZDS 2-wire single-phase oil-cooled O2 motor and supply cable in different lenghts.
Reliable, strong, easy to maintain and available in a wide range of models; it’s ready to use as it doesn’t require a start and run control panel.
It is protected against many possible installation or operation faults thanks to the or the DRP-Plus display monitoring protections device.
 
DRP-Plus
  • LCD display for easy diagnostic
  • Soft start technology
  • Extra torque on start up when necessary
  • Sounder alarm in the event of a fault
  • Ready to use, doesn’t need any further calibration or setting up
  • Self-learning button for possible field approach
DRP-Plus device is designed to guarantee an optimal protection of the QPGo 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. DRP-Plus 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. DRP-Plus 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 DRP-Plus, the QPGo.P.DRP-Plus submersible pump can work and be continuously protected also when actual supply voltage values are at tolerance limit, providing the effectiveness of the protection operation. In addition, DRP-Plus, 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.

Automatic protections

Dry-running protection

Dry-running protection

The device 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), DRP-Plus 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.

Thermal protection

Thermal protection

The special thermal protector integrated in the motor is manually resettable and especially designed to ensure higher reliability and longer life. It stops the motor in case of overheating because of an incorrect installation.

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.
  • The DRP-Plus must NOT be used with a frequency inverter.
