Quick Answers
Frequently asked questions
Answers drawn from the specification tables and datasheets above — ask our sales engineers for anything model-specific.
How deep can COTECH solar water pumps lift, and how much flow do they deliver?
4″ deep-well submersibles (250 – 2200 W) lift up to 150 m of head with flows up to 14.5 m³/h; AC/DC hybrid pumps deliver 40 – 56 m³/h for irrigation mains.
What protections are built into COTECH solar pumps?
Dry-run, overload, over/under-voltage, reverse-polarity and over-temperature protection come as standard.
Can the pumps run at night or on cloudy days?
Yes — AC/DC hybrid models switch to grid or generator power automatically, so water keeps flowing day and night.
What are COTECH solar pumps made of, and what is the motor IP rating?
Wetted parts are SS304 stainless steel and submersible motors are IP68-rated. Permanent-magnet brushless motors with MPPT run 20 – 30% more efficiently than conventional AC pumps, and pool pumps use chlorine-safe plastic wet ends.
