It looks fine, but I could not tell how big the tank is. The true test of any pump is setting it up with a gang valve-two outlest valve -and running air line out of both valves to the floor of the tank. If it can do that you have enough power for a long time to come. If not get a back up pump a size larger. As pumps get old, the diophram gets brittle from heat and age. This causes them to lose pressure and you have a problem. One other piece of advice, if you switch pumps and save the old one you may have a problem if you need it again. Sometimes the diophram seal just gets too weak to hold pressure.
