New 6155 vs 6205, 6305

[Super SS]

Im wondering on the differences between the new 6155 stream pump and the 6205 and 6305.

According to what I can find the 6155 does up to 15000L/H, 6205 does 22000 and the 6305 does 30000

I was going to get 2 of the 6205's but they dont seem to be made any more, and the 6155 seems to flow far less, very similar flow to the 6105.

6155 replaced the 6205, the 6155 is stronger and this flow rating change is related to a different method of measurement, we now use a ultrasound meter to measure output flow, while the old method was theoretical calculation of propeller size and total entrained flow. A 6155 is not much stronger than a 6105, most of the added expense is for a much stronger magnet holder 1.08" vs .59". Yet another stronger model should be out next year to replace 6305, these new models are stronger and quieter.

so is the 6155 quieter than the 6105? Also did the 6105 receive the same impeller change as the 6155 or did it just get the new wide flow kit?

All Stream 2 pumps are transitioning to the quieter fixed shaft and the 6105 is quieter than the 6155 by a little since the prop is smaller, provided it has the new fixed shaft design. All pump shipped for the last month have this design.

Can a old 6105 be retrofitted to the new shaft design?

Only by replacing the motor.
