X.H3F.DRP

X.H3F.DRP Single-phase Complete Solution (220-230V/50 Hz)

4” complete solution made by stainless steel ZDS hydraulic part, DRP-Dry Running Protection, ZDS Control Box (which includes start and run capacitor), single-phase Franklin water-cooled encapsulated motor and supply cable (different lengths available). The X.H3F.DRP Complete Solutions, manufactured to ISO 9001 standards, are available up to the maximum delivery of 15.000 l/h and 300 m head. The DRP is an electronic device that guarantees optimal protection of the pump against dry-running and other possible installations faults or operation failures. In case of water shortage, the DRP stops the pump immediately when water drops below the DRP and it restarts the pump automatically a short time after the water rises above the DRP. Unlike traditional solutions, there is no need for additional cables, sensors or control boxes. The X.H3F.DRP Complete Solutions are designed to be used in applications for lifting, distribution, and pressurisation in civil and industrial water systems, garden irrigation system, filling of pressure vessels and tanks, fire-fighting systems and washing systems, drainage systems, fountains supply.

Automatic protections

Dry-running protection

Dry-running protection

The DRP completely protects the X.H3F.DRP Complete Solution against lack of water in the well, without the aid of other equipment (probes, cables, sensors, control panels, etc.). In case of dry-running, the DRP automatically stops the pump. the DRP restarts the pump after a programmed cycle time.

Overload protection

Overload protection

The ZDS Control Box protects the X.H3F.DRP Complete Solution against overload. In case the pump is partially or totally blocked, the overload protection in the ZDS Control Box stops the pump to protect it.

Protection against too frequent start&stops

Protection against too frequent start&stops

The DRP protects the X.H3F.DRP Complete Solution against leaks in the piping system (also when the 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). In such cases, to avoid potential damages, the DRP makes the pump enter the stand-by mode.

Low voltage protection

Low voltage protection

The DRP protects the X.H3F.DRP Complete Solution against low voltage, that can damage the motor. Low voltage can occur, for example, if the section of the power cable is not adequate considering the motor power and the distance between the plug and the pump itself; or if a generator is faulty or undersized for the pump.

Voltage peaks protection

Voltage peaks protection

The DRP protects the X.H3F.DRP Complete Solution against voltage peaks, which can be caused by electric abnormalities in the supply network or by other various electrical interferences. It reduces overvoltage, keeping the correct operating voltage range.

Information on a proper installation

  • The correct pump must be selected considering the delivery pressure and the characteristics of the plant.
  • During installation of the submersible pump, it is necessary to verify if the power supply voltage is correct.
  • The correct pump operation is guaranteed when the power cable section is correctly selected, considering the motor power and the distance between the pump and the plug itself.
  • 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.
  • To guarantee automatic operation mode (the pump starts and stops when open and close the tap) it is necessary to connect a pressure switch and a pressure tank of the correct size, if the plant is not already provided with them.
  • We recommend to install a proper cooling jacket in installations bigger than 10 cm, to guarantee the correct motor cooling flow.
  • The maximum quantity of sand allowed in the pumped water is 120g/m³.
  • The DRP must NOT be used with a frequency inverter.
  • DRP doesn’ t work with demineralized water (such as rain water).
  • DRP must not be used as a float.
  • The DRP must be immersed in the same water as the pump in order to ensure continuity between the DRP and the pump casing.
  • In order to reset the electronic protections, disconnect the pump power, wait 10 seconds, then plug it in again.
  • In order to reset the overload protection sensor, it is necessary to press the appropriate button on the CBH.
