Normally, you should be able to run your pump 24/7 for weeks or even months on end and while it might get hot, it shouldn't get too hot to touch. If it does, something else is going on.
Have you back washed recently. If not, do so. A pump works better with a clean filter. Watch the pressure gauge. After you backwash, note your "clean" pressure. When the pressure goes up 5 psi, or the pump starts getting hot again, backwash again.
