4” submersible pumps powered by renewable energy sources

4HS MultiPower pumps powered by renewable energy sources, is a new range from 4HS pumps with built-in inverter.

4HS MultiPower pumps can be powered by AC or DC with a wide range of operating voltage (90 - 265 VAC / 90 - 400 VDC). This me-ans that 4HS MP pumps can be connected to solar panels, batteries, wind turbine and a diesel generator.

A special software algorithm allows for adjusting the hydraulic per-formance to each source and to the available power while maximi-sing the amount of water pumped.

The built-in electronics insi-de the motor avoid the use of shielded cables and output fil-ters, and it is the ideal solution for any application in remote

locations without surveillance and climatically adverse.

In fact, in the traditional solu-tions, the solar inverter is pla-

ced above ground and, being exposed to the weather, could suffer of:

Overheating

Water infiltration

Thermal shock

Damage by animals or people

The built-in electronics are directly cooled by the water flow; the operating tempera-ture of the electronic compo-nents is so low as to ensure considerably longer life than a surface inverter affected by high temperatures, humidity, dust and sunlight.

control pump start and stop, connecting a float switch, for example. All the protections against overload, surges and dry running are integrated into the on-board inverter.

If the signal cables are connected to the CM MultiPower control module, it is possible to:

Control the electric parame-ters (current, power, voltage).

Record and store all the alar-ms related to the working hours.

Connect a pressure or a flow sensor to monitor the pump’s performance.

Connect a pressure or float switch.

Provide an alarm digital output for remote control.

4HS MultiPower pump can be installed with CM MultiPower control module or without it, thus becoming a “plug and pump” system.

If the CM MultiPower con-trol module is not used, si-gnal cables can be used to

ACDC

Use of auxiliary genset

Integrated on-board protection

If solar energy is absent or insufficient, it is possible to power the pump with an auxi-liary genset to achieve the de-sired pump performance.

An AC/DC selector is used to change the power source.

Protection against overload, surges and dry running are integrated into the pump’s electronic circuit.

Electronic protection against dry running avoids the use of probes.

Based on the varying conditions of solar irradiation and tem-perature, MPPT (Maximum Power Point Tracking) maximises the electrical power drawn from the panels and therefore the amount of water pumped.

The greater the solar irradiation the faster the pump’s rotation speed, and consequently water flow increases.

When solar irradiation decreases (due to clouds or the different times of day), the pump reduces frequency and therefore the flow, but it continues to provide water until the irradiation falls below a minimum level necessary to ensure operation.

The helical rotor pump

Permanent magnet motor

4HS “H” pumps are equipped with a helical rotor that moves within a double-helix rubber stator.

The rotor is made of AISI 304 stainless steel and coated with a hard chrome surface.

During operation, the rotor mo-ves on the rubber surface and is lubricated by the pumped water.

The flow rate is directly propor-tional to the pump speed while the pressure supplied is kept al-most constant.

In this way, unlike a centrifugal pump, the helical rotor pump provides high head even at low rpm, ensuring water on surfa-ce even with very low available power or low solar irradiation.

In addition, the helical rotor pu-mps feature higher hydraulic

4HS MP pumps are equipped with a permanent magnet mo-tor.

The rotor uses Neodymium ma-gnets coated with thin layers of copper and nickel to ensure greater reliability and durability in addition to superior magne-tic performance.

High motor efficiency and star-ting torque make it possible for the pump to run even in low-light conditions.

The integrated inverter module converts DC energy into useful electrical energy to drive the motor efficiently and, at the same time, adjusts the pump

daily radiation can then be con-sidered as the number of hours the pump works with 1 kW/m2, the value of reference for defi-ning solar panel performance.

Dividing the required water quantity by the hours, nominal flow is calculated and, in addi-tion to the required head, the right pump can be selected.

For the correct selection of a 4HS MultiPower pump to be used in a photovoltaic system, it is necessary to know:
