Pond pro is definitely a salesman. These gast pumps are industrial grade pumps ran in different industries across the globe. If youre rebuilding the rotary vane pump every year you have a bigger problem than the pump. On a new pump with pressure relief valve and proper set up, I was told these pumps have ran 20 years without a rebuild. I believe that based on how these pumps are built and designed for 24/7 manufacturing. I thought about going vertex in the beginning, but based on what you get for the price, it'd be a hard sell to someone like Warren Buffet even!
