■ Special upper pump bearing as a standard

■ Generously dimensioned intermediate bearing prevents shaft displacement and enables optimum lubrication


Low operating costs

■ Consistently high efficiencies by optimised

hydraulic design

■ Low-loss non-return valve


High energy efficiency

■ Meets the European requirements for energy-efficient operation of water pumps


Trouble-free long-term operation

■ Made completely of high-grade stainless steel


■ Smart MPPT(Maximum Power Point Tracking)

■ dry running protection  over-current protection, input over/under voltage protection, overload protection, module overtemperature protection, grounding protection,reverse protection, speed protection.

Inverter allows using grid or diesel generator as backup power supply, 24-hour running.
