NERA SOLAR Submersible Water Pumps - Water Pumps

The most compact and reliable solution for solar pumping applications.
NERA solar pumps have been developed to meet the needs of low-power and low-cost pumping systems without sacrificing quality, reliability and performance.

SOLAR CENTRIFUGAL WATER PUMPS

• Impellers and diffusers in AISI 304 stainless steel.
• Built-in no-return valve.

SOLAR SUBMERSIBLE WATER PUMPS ENCAPSULATED ELECTRONICS

• High-efficiency encapsulated inverter.
• MPPT for maximum flow in all weather conditions.
• Overload, overheating and dry-run protected.
• Removable power cable.
• Water level sensor.

SOLAR SUBMERSIBLE HELICAL ROTOR WATER PUMPS

NERA 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 moves on the rubber surface and it’s lubricated by the pumped water. The flow rate is directly proportional to pump speed while the pres-sure supplied is kept almost constant.

In this way, unlike a centrifugal pump, the helical rotor pump provides high head even at low rpm, ensuring water on surface even with very low available power or low irradiation. In addition, the helical rotor pumps feature higher hydraulic efficiency than centrifugal pumps of same flow.

This saves in the number of PV panels necessary for the application.

SOLAR SUBMERSIBLE WATER PUMP MOTORS

• High efficiency permanent magnet motor.
• Resined and encapsulated stator made of AISI 304stainless steel.
• Water-cooled rotor.
• Kingsbury thrust bearing.
