    The one mm beyond the 3A fuse is fine, any 1mm before that fuse really  needs to see a PSSC that will clear the 40A breaker before the 1mm2 over heats.

    Depending on the zone the transformer secondary wiring is in , the transformer may need to be SELV or can be  just PELV . In any case I'm assuming transformer and pump are a kit, and as such it falls to maker's instructions,  I'm also assuming the pump operated of a voltage less than 50 ?

    So wthout that extra info, probably OK, but needs checking.
