I assume my WP40's are the new version, as I noticed they don't exactly match the enclosed instruction sheet. My controller has 3 constant speed levels (H1, H2, H3) while the instructions only list 2 (H, L). And the W1 pulse control has 3 speed positions as well (S1, S2, S3). So that gives you a few speed options.

I'm running a couple pumps in the bath tub right now. They seem to work well. I do notice, though, the pulse duration knob doesn't seem to give much range for a wave duration cycle.

I also have the Coralife Wavemaker pumps (DC5800) and their pulse cycle is up to 60 seconds. I found that on the short cycle (about 5 seconds) it was too hard on the pumps (ramping up from low power to full blast), and I had wear on the shafts and bushings. But Coralife replaced them (lifetime warranty), and I now run them at the longer cycle, and they seem to be holding up OK for now.

So I hope these WP40s are tough enough to handle a short high powered pulse duration (no power to full every few seconds). They are cheap, though, so not a big loss if they don't last too long.

Solutions are easy. The real difficulty lies in discovering the problem.
