Beckett Air flow:

For lack of a better place, I'll put this here for now: Here is a test chart of air flow, as driven by a 1/12hp Sequence 3600.

Pumps and Pump supplies:

Not currently available, but support is still offered for existing customers.

All pumps ship directly from the distributor to you.

Suggested pumps for my skimmers:

• SK1020: Mag 18 or Mag 24
• SK1220, 1620: Iwaki 55, LG4MDQ-SC, Sequence 3600
• SK4020, SK5020: Iwaki 55, Iwaki 70, LG4MDQ-SC, Sequence 3600
• SK4220, SK5220: Iwaki 100, Sequence 5200, dual Iwaki 55
• SK8020: Dual Iwaki 70's, or dual Iwaki 100's, depending on your tank size.

Sequence:

Three year warranty, Salt water seals and hardware. Direct drive. The 750 series works great for closed loops, or as a tank return. They are not high-pressure pumps, so don't run the skimmers well. I have run a 3600 on a SK5000, and it runs, but not as well as an Iwaki 55 does. These are very quiet pumps.
