Hi good night, I just received a motor replacement for my filter pump it's a super pump Hayward 2 hp. Now the original motor it’s a 3/4 hp. The pool is in ground 30000 gallons. The piping is 1.5 inches diameter. Would this new 2 hp its motor be okay to install?

It is ok to install. The motor does not determine the strength of the pump. The impeller determines the pump's head curve (aka strength). So when you run a larger motor on a smaller impeller, the motor will draw much less power than the rating of the motor but the performance of the pump is nearly identical. Unfortunately, this also means it may not be as efficient as the smaller motor but probably not by much.
