Roy,

Good question that I do not know the answer to. The E2182 is one of the recommended pumps on many of the discussion boards. After I read your post I double checked and noticed that I pulled what would be the E2000, a part number suggested on Binder Planet. The E2000 does flow less, 30PSI up to 90PSI.
