Hi everyone,
I will be glade to hear your opinion about a submerged wastewater pump (Efficiency = 32%).
Is it exploitable ?
Thanks in advance.

That sounds like EPDM rubber jacket, typical for SOW cord.

One trick I have learned is to run the cable in a plastic tubing as use compression fittings instead of cable glands. It's much less expensive to by chemical resistance in tubing than in cable. FEP tubing covers a very broad range and works well with compression fittings.
