Awesome help, thanks. The pump is relatively new, and I only use it for hot water, no wort recirculation. But I'll try shortening the hose, and turning the head 90 degrees and see where that gets me to start with.

Thank you!

If you have the "HS" models or High Speed (3400rpm motors) then all you need to do is order the 815 impeller which is part number 0809-0107-0200

Hmmm not sure why if failed but anyway....go and cal any one of our distributors and ask for a "Wet end Kit" for either the AC-5B-MD or the AC-5PS-MD they are in essence the same pump...only difference is the 5PS version has the motor bracket out of Polysulfone and has no plug on the cord....more for the industrial side of things. Either way its the same pump head. :)

Thanks Walter! I just ran through a dry run (well, wet run, cold water). I put an elbow on the inflow, turned the head 90 degrees, and shortened the hose length from 6-7 feet down to about 2 1/2 feet. That sucker pumped harde that a thai schoolgirl on recess!

MUCH BETTER!

Thanks!

What's the difference between the 809HS and the 815HS? Are they the same thing?

Sorry for the late reply...for some reason its not sending me notifications when there are new reply's...

Anyway the difference is the impeller inside the pump. You can convert your HS model to the 815 specs by swapping out the impeller with part# 0809-0107-0200

Walter,

How would I order a plastic motor bracket (Item 21, Part Number 0809-0058-1000) on the drawing. http://www.marchpump.com/site/files/966 ... Manual.pdf

Morebeer customer service indicated that was not a part they carried or would be able to order. Any suggestions? Thanks.
