Pump seized......crap

I have an Iwaki 100 back up on the shelf.
( 2000 gph ,13psi, 39 ft of head)if you need to use it. Also a spare mag 9.5.
 
Thanks everyone, I'm good for the moment with the first replacement Blowhole up and running.

Hoping ReeFlo responds tmrw about the second seized pump.

SkiFletch no idea what's actually wrong with the pump other than it just stopped working..

1 inch return with no flow restrictions
 
Will Reeflo let you take the pump apart to see if the bearing impeller is seized to the housing, or if the shaft is seized in the bearing?
 
My "traditional" reeflow gets nervous with small rocks sucked into the intake. I have a sponge in the "bubble trap" to limit grit but I have two incidents with rocks (one noisy, and one reduced flow). I have not used the BH series but would expect minimums for inlet feed (the manual is very clear about 1.5") and how abrasive the water is. If you are able to get a post-mortium I would be interested.

The minimum inlet out let is 1" on this pump, and that's exactly what I am using. I also have a bulkhead strainer in place to avoid anything getting inside the pump.
 
I've never seen an external centrifugal pump pushing 10+ feet of head happy with 1" inlet plumbing. Outlet, OK you can get away with that, but inlet plumbing would do MUCH better at 1.5 inch. I strongly suggest this is at the root of your. Just like "minimum" code isn't always sufficient in homes, minimum pipe diameter isn't always the best here. Is/was the motor too hot to touch while it was running? It should be warm, maybe even hot to the touch, but never "omg this thing is way too hot to even touch for a millisecond hot.
 
When the pump is running normal it may be warm to the touch but that's it. The only time it got extremely hot was when they seized.

I understand the concept of the larger inlet but the BlowHole is designed with a 1" inlet and outlet.

I guess I could run large larger size but would have to downsize to 1" as it enters the pump anyway.
 
ReeFlo is sending me an upgrade, the new BH2700 to replace the seized up BH1450 pump.

Once again excellent customer service.

Unbelievable as it may seem, I just had a second pump seize within the past month.

The first pump seized up on April 9th which ReeFlo replaced without issue. While waiting for the replacement to arrive I purchased a second pump to get my tank up and running.This is the pump that seized up yesterday morning.

Fortunately the original replacement was waiting in the wings and I had the tank back and running in minutes. But now I am really nervous, I'm going on vacation in two months and while I have someone to check on the tank I have no one to replace a pump if needed. I just want to be able to trust the pump.

I still do like the BlowHole pump, its very quiet and gives me the perfect flow. Strange that both pumps failed after one month of operation. Guess I will see what happens in the beginning of June.

One other interesting note is that both BlowHole 1450 pumps that seized were purchased from Dr Fosters and Smith

CRAP!!! Mine is 1 month old and I have the same pump from Dr Foster and Smith. I got it on sale... I go on vacation for a week in August! Is this pump safe on low pumping 5ft height?
Should I connect my backup for vacation?
 
I would think 5ft height on low would be fine. In my case I was running about 13ft head height on medium but the biggest issue was the plumbing restricting flow into the pump.

After upgrading to the BH2700 and redoing the inlet plumbing I have not had a problem.

My pump is located on the backside of my stand with a one inch inlet. Should I have a 2 inch inlet and then reduce it right before it hits the pump to reduce restriction? Or does it not matter since it only runs on low?

Thanks for the advice.
 
1 inch should be fine, I had that also but I also had a 90, union and 1 inch ball valve that all added the the restiction.
