you would need the entire 5B assembly....so you would need the impeller, front and rear housing...then have the impeller milled down and re-use all the rest of the parts like the shaft, thrust washer, o-ring, and screws from the old pump.

Hi Walter. Quick question. I'm curious if the polysulfone 809 heads and the SS 809 heads both use the same o-ring? I'm having a hell of a time getting the 809 o-ring for a polysulfone head to stay in the groove of the SS head while I assemble the SS ones. I could lube it up with some silicone grease but I'm reluctant to do so if I do not need to as it is close to my hot wort.

The polysulfone head obviously doesn't have the two sided o-ring gland like the steel one, which in theory could mean you have two different sized o-rings. If not, any tips on getting the o-ring to stay seated in the gland on the SS head? If so, got a part number for the o-rings for the SS heads?

Thanks in advance.

The o-rings are different between the plastic and metal pumps......you needs part# 0809-0165-1000 thats for all the metal 809's. The plastic pumps have an o-ring that about .072 smaller so it would be a PITA to try and get it to fit.

or if you have a good local supply house handy then find a food grade o-ring with an ID of 2.441 and a cross section of.070

Why is the 815-pl-c not listed by Marsh under Homebrew Pumps. If you click on the listing it includes homebrew as a use. Is it designed to recirculate boil wort? Thanks

What is the duty cycle for an 809 pump? Thinking about using it with my RIMS tube as a sous vide cooker, but not sure if running it for 5-10 hours straight is a good idea or not. Thanks.

I asked a similar question a few months ago. It's apparently actually fine to run 24/7, as I had suspected, as long as it's not being run dry.

The 815 doesn't come standard with a plug on the end...the beer pumps do...it can be built that way but its not a standard off the shelf type item for us here..that's pretty much the only reason...

All of our pumps are designed for 24/7 operation. And running them 24/7 the motor mfg tells us that the motors should last anywhere from 3-5 years...but we have found them to much longer then that.

Walter,

I'm looking into setting up an 809 with stock impeller for pumping a fixed volume up to a higher vessel in cycles. The system will be automated, so I'm looking into using a check valve to prevent the liquid in the output tubing above the pump from draining backwards when the pump shuts off. Priming won't be an issue, I just want to prevent gravity from adding back the volume of the hose above the source when the pump shuts off.

What should I look for specs wise on a check valve for this application? I don't know what kind of cracking pressure the pump will work with.

Thanks!
