stream pumps

[ujohnk]

Hi Roger,
At the moment i have 2x Tunze 7300/2 and 1x Tunze 7400/2,
Is there any kit you can buy to turn these pumps into stream pumps?
Thanks John..

It depends. In order to work reliably the pumps have to have been made after April of 2003. Older pumps have a different driver that may work but could be too sensitive to sounding the alarm and not have the proper start up program for the slightly higher draw of the propeller. Kit Update6100 can convert a 7400 to a 6100 Stream. The 7300 could be converted but this would yield a non existant model somewhere between a 6000 and 6100 in output.

Thanks Roger,
I will try to see if i can get one of the kits in the Uk and give the 7400 a try.
Cheers John...
