In my experience, Blastfire pumps are the most durable pumps out there. I used 3 of them to replace my Sm5k's pumps once the stock ones broke, and the Bf pumps have worked fine for about a year. They have all had their pumps plugged.
I'm not so sure about using them with any integrations, but if you are that concerned with it breaking, then just go with a 2k pump.
