Water pumps

Atersa has a full line of DC and AC water pumps, from pumps with small flow rates for household use to submersible pumps for irrigation or rural water supply. Atersa sells 4 different types of water pump: 

DC pumping system

This pumping system is equipped with a DC/DC coupling converter to convert excess voltage from solar panels into current for maximum system performance.

It has an SAS submersible pump and a PM5 coupling converter. It is mainly used for extracting small amounts of water from depths down to 70 metres.


Storage battery pumping system

This pumping system can be operated at all times, even outside daylight hours. It comes in DC and AC versions.

EasySun Pump - ESP Powered by Fuji Electric

The EasySun Pump “Powered by Fuji” pumping system is a connection and control arrangement for independent water pumping powered by solar panels. It can also be connected to the electrical grid or to a generator set. The ESP panel allows all possible combinations.

It offers many advantages, in particular:

  • Ten standard models from 2 to 30kW, direct connection without batteries, producing an extremely fast return on investment.
  • Comes in IP20 and IP54 ratings.
  • On-screen keyboard with LED display.
  • DV/DT filter for up to 200 metres included, depending on the model.
  • Continuous Maximum Power Point Tracking (MPPT) of the solar panels, capable of improving performance by up to 25%.
  • Start-up and shut-down interval management in low irradiance conditions to prolong pump motor service life.
  • Input terminals are disconnected fuse holders for series protection and easy installation, testing, and start-up.
  • Acceleration/deceleration control on/off switch.


EasySun Pump-POOL

The EasySun Pump Pool system is the complete solution for direct solar power supply to water pumps for swimming pool filtering systems. Powered directly without batteries, it provides a single solution for year-round use.


There are solutions for pool filter pumps ranging from 40 m3 up to 2,350 m3 and offers the following advantages:

  • Zero energy cost: direct connection without batteries, producing an extremely fast return on investment.
  • Comes with a variator to avoid water hammer when turned on for longer conventional filter motor service life.
  • Silent, efficient, fully automatic running.
  • Modular design to fit every pool size.
  • Few separate components for simple, inexpensive maintenance.
  • Fast, easy installation: direct replacement of the existing pool pump.
  • All pump materials are high-quality, corrosion-resistant.
  • Operates on direct solar power; does not have to be connected to the grid, completely independent running.
  • Continuous Maximum Power Point Tracking (MPPT) technology to maximise solar panel power output.
