توضیحات:
Centrifugal pump.
Impellers and diffusers in AISI 304 stainless steel.
Built-in no-return valve.
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.
Helical rotor pump.
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.
Motor.
High efficiency permanent magnet motor.
Resined and encapsulated stator made of AISI 304stainless steel.
Water-cooled rotor.
