K2579 Connection

I have just constructed the K2579 timer and am looking for some assistance with connecting it with the submersible pump that it will be operating with. I am a bit confused with the NO and NC. I am looking to run the pump on/off in equal intervals. I also was curious about the snubber network. Would I need to connect one with this application, if so, how would I go about doing that. Any help would be appreciated.

Please note that this is not an interval timer.
You need either MK111 or K8015 for interval timing.
Interrupt pump live and connect to COM - NO.

Thanks for the info! I bought the MK111, but am not sure if it will work with a 23W submersible pump. The output says MAX 24V so I was wondering if I need to make any mods to account for this.
