What relay is suitable for a submersible water pump
The switch ratings of the relay must be at least what you want to use it with, which is the case for your relay:

use with 220/230V, rated 250VAC
use with 0.072A, rated 10A


That module has 5V relays, why do you want 9V? You could use an 7805 to reduce 9V to 5V.
