Unfortunately neither the Iwaki 70 or 100 will work with the Wavemaster Pro as it is only rated at 120 watts per pump (360 watts total for three pumps) and the 70 runs over 300 watts and the 100 is about 400 watts.

If all you are planning to do is to operate these in a close loop system then these pumps are probably not all that appropriate anyway as they are fairly high pressure rated pumps (30-40' max heads) which is uneccessary in a close loop circulation system that operates into very little head.

Have you considered the Dolphin AmpMaster series? These pumps are primarily designed to give high flow rate (as high or higher than the Iwakis) but with little or no head capability (max heads run barely over 10'). They require much less current (typically 1 amp or less) and most would fit within the Wavemasters operating limits (though near its max). I never have used one of these with a wavemaker so you will likely have to ask around to find out if they are compatible operating in this mode (in this case the manufacture may very well be able to give you guidance on this). The other aspect of using this pump or one like it is that you normally have to run larger diameter plumbing (or parallel lines) to minimize head loss due to the pumps poor pressure capabilities.

Again, I am assuming that you are purely running these pumps in a pure closed loop circulation system, if any inline filters or if the plumbing runs are excessive (>10-15') then the low pressure pumps are less appropriate depending on what your flow rate goals are. If you do need more pressure capability then you need to find a wavemaker system more capable than the wavemaster that will handle more powerful pumps such as the Iwakis.
