Your chances are 50/50...we have two SEIOs. One of them has been working great with the wavemaker since we bought it (three months), and the other started seizing up when hooked into the WM after a month's usage. That one still works, but cannot be used on the WM. The mfg. does not recommend that you use these pumps with wavemakers. Do you have SEIO pumps, or are you just considering purchasing?
