I recently purchased a Jabsco Model 31801-1305 diapram pump. It worked great for moving my bio around. Lately it is almost impossible to prime and pumps slow. I suspect it has nitrile diaphram and valves in it. The parts breakdown shows there is vitron parts available for it but I have been unable to contact any suppliers for it.
Any suggestions?

Thanks Don
I got into their catalog but didn't have any luck with viton so I'll call and see if they're available.

 

Well..so much for that plan. I can't replace the diaphram and valves on that pump (Jabsco 31801-1305) with oil resistant. Hell, I can't even replace them with OEM. I guess Jabsco doesn't manufacture that model any more. What a waste of money that was.

 

Hate it when that happens, go to get replacement parts and they are no longer made. Had a motor-tool that broke a $3.00 spring and ended up having to replace the whole tool because the spring is no longer made...

 

I deal with these pumps.
Go look at Graingers and or McMaster Carr.
They'll find something for ya.

 

Tks, I'll check it out.

 

I'm not 100% on your type of pump, but with any pump of this type, don't deadhead it if you can help it, and if it has check ***** on the suction side, make sure they are seating well.
Most times these pumps are condemned it is just inability to make suction, or forcing pressure through the suction side.
