With a 3 HP pump, I would be much more concerned that you may be exceceding the filter's flow rate than the PSI rating. It is difficult to exceed the pressure ratings on filters but it is much easier to exceed the flow rate of the filter with a high HP pump.
Also, with a 3 HP pump, high pressure will be the norm unless you have extremly large pipes. Again, it is likely that you have very high flow rates which are causing the high PSI rise.
24 PSI is 55 feet of return head and adding 10 feet for the suction gives you about 65 feet of head. Not sure of the brand of pump but a high efficiency 3 HP Northstar pump at 65 feet of head will give you as much as 165 GPM. I would check on the flow rate maximum of your filter to see if it exceeds that value. Depending on the filter type, that could be a problem.
