E.X.H3F

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

4” complete solution made of stainless steel ZDS hydraulic part, ZDS Master 1 control panel, single-phase encapsulated water-cooled PSC Franklin motor and supply cable (different lengths available). The E.X.H3F Complete Solutions, manufactured according to ISO 9001 standards, are available up to the maximum delivery of 15.000 l/h and 300 m head. The advanced technology and settings of ZDS Master 1 control panel guarantee the best accuracy of working in every voltage condition. ZDS Master 1 control panel is extremely precise since it works with cosφ and current, and it is set according to technical data of the selected hydraulic and motor. ZDS Master 1 control panel is ready to use and protects the E.X.H3F Complete Solution against abnormalities in the installations and against many other possible faults. The E.X.H3F Complete Solutions 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

Dry-running protection

Dry-running protection

The E.X.H3F Complete Solution is completely protected against lack of water in the well or in the tank. In case of dry running the ZDS Master 1 control panel stops the pump and a light starts flashing to inform the user that the water level is not sufficient.

Overload protection

Overload protection

The E.X.H3F Complete Solution is completely protected against overload. In case the pump is partially or totally blocked, the ZDS Master 1 control panel stops the pump and a light starts flashing to inform the user.

Protection against low/high voltage

Protection against low/high voltage

The E.X.H3F Complete Solutions are protected against low or high 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 iteself; or if a generator is faulty or undersized for the pump. High voltage can occur with unstable supply network or with a faulty generator. To avoid potential damages, the Master 1 control panel restarts the pump when the correct voltage is restored.

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 (i.e. if the tank is too small for the system), ZDS Master 1 control panel automatically stops the E.X.H3F Complete Solution and a light starts flashing to inform the user.

Protection against electrical abnormalities

Protection against electrical abnormalities

It can also occur that many operations in the electrical circuits, many starts of motors connected to the same network, possible surges in the network or an inadequate power generator etc. might damage the pump. ZDS Master 1 control panel protects the E.X.H3F Complete Solutions from voltage fluctuations caused by potential electrical abnormalities in the supply network .

Information on a proper installation

  • The correct pump must be selected considering the delivery pressure and the characteristics of the plant.
  • During installation of a motor/pump, it is necessary to verify if the power supply voltage is correct.
  • The correct operation of E.X.H3F Complete Solutions is guaranteed when ZDS Master 1 control panel is programmed according to its cable length. When the application requires cable length or cable section different from those delivered together with the Complete Solution, ZDS Master 1 control panel need to be preset accordingly.
  • 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/³.
