troubleshooting a vertical multi-stage pump

thread407-263167

Hi I have recently installed a newly recondition drive motor of a Floway pump. the problem is during testing the pump is operating in low pressure. we only tested it for a little while because we could not see any immediate change in pressure gauge that would detect whether there is flow.

as I was reading on installation guide of possible cause of low pressure, it mentioned that there is a possible reason that the cause of low pressure is air.

I was thinking that since we did not test it longer maybe air is present on the pipe line that is why the pump is not delivering well, should we have tested it longer to eliminate this? or could anyone tell me how to commission an installed pump.

Before your "technicians" put chain tongs and cheater pipes on the pump, give Weir a call (or email). It looks like the pump Serial# you gave above; just send it along with basic questions, a request for a manual, or a Weir certified shop (most likely their Distributor) in your area.

They may be more expensive than the pump is worth and you may not want to use them, but at least asking that way will get you some info. Look for Walter Lee's name; he is a big shot with the vertical group in Fresno; but is a very good guy and will forward your info to the right person.

-----Actually I checked Weir website and they do not have a local service center available here in the Philippines and I tried googling for a distributor, unfortunately the listed company I found on google does not pick up their phone anymore.

Do you happen to know which department Walter Lee is under, I think my last shot for guidance is by calling fresco office once I get more information regarding this pump.


-Thank you everyone for the help.

Artisi's office is probably where you will get directed, but Walter Lee is VP Products/Sales. He is in Fresno, Ca
walter.lee@wierminerals.com If he doesn't help you, tell him you know somebody in Houston that will personally come and kick his skinny butt.

We were able to pull out the pump today. immediately I saw where was the problem coming from, there is a huge hole near the thread of the casing.
