QPGo.P Single-phase Complete Pump (1x220-230V / 50 Hz)

4” complete submersible pump made of ZDS technopolimer hydraulic part, 2-wire single-phase oil-cooled O2 motor and supply cable (different lengths available). These complete pumps, manufactured to ISO 9001 standards, are available up to the maximum delivery of 6.000 l/h and 150 m head. The O2 motor does not require a start and run control box, as the capacitor is built into it. The QPGo.P complete pumps are designed to be used in the following applications: lifting, distribution, and pressurisation in civil and industrial water systems, garden irrigation systems, filling of pressure vessels and tanks, fire-fighting systems and washing systems, drainage systems, fountains supply.

Automatic protections

Thermal protection

Thermal protection

The QPGo.P complete pump is automatically protected against motor overheating. This can happen because of: the high temperature of the pumped liquid; when the minimum distance between the pump installed and the well bottom isn’ t respected; when the pump is installed in well/tanks bigger than 4” without a proper cooling system; when the pump works in shut-off.

Current overload protection

Current overload protection

The QPGo.P complete pump is protected against against overload. In case the pump is partially or totally blocked, it automatically restarts as soon as the correct working temperature parameters are restored.

Model performance


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.
  • In order to reset the thermal protections, disconnect the pump power, wait that the correct working temperature parameters are restored, then plug it in again.
