4” submersible pumps powered by renewable energy sources

nastec.eu

4HS MultiPower pumps powered by renewable energy sources, is a new range coming 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 diesel generator.

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

The built-in electronics inside the motor avoids 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

Damaging by animals or people

The built-in electronic is direct-ly cooled by the water flow; the operating temperature of the electronic components is so low as to ensure considerably longer life than a on-surface in-verter affected by high tempe-rature, humidity, dust and solar irradiation.

control pump start and stop, connecting, for example, a flo-at switch. All the protections against overload, overvoltage 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 control the pump performances.

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, so 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 protections

If solar energy is absent or not enough, it is possible to feed the pump with an auxiliary genset to grant the desidered pump performances.

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

Protections against overvolta-ge, overload and dry running are integrated into the pump electronic circuit.

Electronic protection against dry running avoids the use of the probes.

MPPT (Maximum Power Point Tracking) maximizes, for various conditions of irradiation and temperature, the electrical power drawn from the panels so the amount of pumped water.

When the irradiation grows, the pump increases its rotation speed and so water flow increases.

When the irradiation decreases (passage of clouds or different times of the day), the pump reduces the frequency and thus the flow but continues to provide water until the irradiation does not fall below a minimum necessary to ensure the operation.

The helical rotor pump

Permanent magnet motor

The 4HS “H” pumps are equip-ped 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 it’s lubricated by the pumped water.

The flow rate is directly pro-portional to 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 irradiation.

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

The 4HS MP pumps are equip-ped with permanent magnet motor.

The rotor uses Neodymium ma-gnets coated with thin layers of Copper and Nickel, to ensure, in addition to superior magnetic performance, greater reliability and durability.

High motor efficiency and high starting torque make pump mo-ving even in low light conditions.

The integrated inverter modu-le realizes the conversion from DC energy into useful electrical energy to drive the engine ef-ficiently and, at the same time, adjusts the pump speed in rela-

efficiency than centrifugal pu-mps of same flow. This saves in the number of PV panels ne-cessary for the application.

ber of hours pump works with 1 kW/m2, standard value to whi-ch PV panels performances are referred.

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

For the correct selection of a 4HS MultiPower pump to be used in a photovoltaic (PV) sy-stem, it is necessary to know:

Desired daily water quantity.

Total head (static+dynamic).

Installation location.

Based on location it is pos-sible to get average daily radiation [kWh/m2/day]. Ave-rage daily radiation could be then considered as the num-
