Teflon and silicone is what I use every day. 4 wraps or so of Teflon with a bead of silicone around the base (where the threads first touch the pump) of the fitting.
I wouldn't use white PVC on the pump fitting though, it's more prone to heat damage/warping. You want to use gray cpvc for at least a few inches. Even better would be a threaded Union like this 2" one or like this 1.5" one. The union gives you a way to break apart the plumbing later on for future repairs without having to cut it apart. Those unions are hi-temp rated to help prevent heat warping.
