Blue-white pump issue

[washregal]

I am using a blue white pump I believe a C-1700N series with the duel injection to chemical feed my in bay automatic for pre-soak.

The other day it seems like it just stopped pushing product through. The pump sounds like it is working.. could it be clogged? Is there any way to fix the clogg if so? would it make sense to replace the pump heads and not the entire pump.. I am not in a position to replace a 400.00 pump right now.

Let me know your thoughts when you have a moment.

You may want to look at the check valves in the pump and the foot valve on the hose in your chemical bucket. A stuck check valve will make it stop pumping. There is one at the inlet and outlet of the pump. Kleen rite sells all the parts to rebuild it. The only other thing is the diaphram may have a hole in it.

Sparkey is right. I used to use a lot of these pumps and they can be hard to deal with. I bought some simple John Guest check valves that are the push lock type for 3/8 OD tubing. I would use these on the lines up to the pump and after the pump instead of buying the expensive blue white replacment parts. The pump works fine with these in place of the ceramic ball and swelling Orings you find in the blue white pump. Just take out the ceramic ball or the bullet ck. valve.
Before buying another pump I would replumb your injector to use a simple venturi injector. A .83 or .98 injector should work. Then you just install the correct injector tip. Cost to do this would be under $50.

If one of the diaphrams has a hole in it you should get a leak out of the weep hole that is on the back side of the diaphram. The diaphrams in mine are laminated with a chemical resistant material on the wet side. I suppose it is possible for the lamination to come apart and affect the effectiveness of the diaphram, but I have not experienced this.
My issues with them have been the same as the other replies. The bullet check valves can be a pain and seem to be the weak part of the system. The Blue White website gives instructions to clean them by running vinegar through them. I haven't tried this. I usually disassemble them to clean them.
With all this said, I would start with the foot valves and then the bullet check valves that are on the pump.

If you can do without the pump for a several days you can send it into Blue-White fora free evaluation. They have a 3-day turnaround. Below is contact info for the person who handled my eval.

Wow, I had not thought about Blue White Pumps for 8 or 9 years. It brings back memories of nightmares of problems. Soapy gave you the best solution. We adapted it long ago and have never again thought about a BW problem.

How would you go about replumbing with a venturi injector?

Could you explain more in detail. I'm new to this forum. I have a Ryko Softgloss XS. Do you still use the Blue and White pump? My pumps are in the mechanical room then pumped up the wall 10' then over to the automatic. Any help would be very much appreciated!! I installed the John Guest check valves. Hopefully this will eliminate adjusting the pumps or cleaning them.

With a chemical injector you would not need the pumps. ON the water line going out to the bay the injector would go in line that line and as water flows out to the bay it creates a venturi or vacuum effect that will draw the chemical. On rykos newer touchfree units they ahve gone to injector completly and dno't use the blue white pumps.
