I noticed that there is a rise in the suction line immediately before the pump. I’ve always been taught that the suction must always be rising. Can you explain why this is not always the case?
15 to 20 thou on the wear face is a given in the pulp industry, mechanical seals suck!!!!! packing is so much better!! 8$ dollars vs $5k dollars for saved water....
When i checked the shaft runout, i take several points along the shaft, start from coupling end to impeller end, checked the surface condition if any damage on it.
This a well designed assembly. Kudos to the design and manufacturing team. Any comments from the maintenance engineers among us who have service this type of pump?
It works as designed. Servicing the rotor and stator can take half the time, if not less, depending on your setup and dimensional constraints. As reliable as the legacy models. If ragging is an issue, the service port alone can sometimes prove useful in diagnosing, if not outright clearing the issue.
Ribs on the reverse side of the impeller increase strength, but when pumping abrasive water-sand mixtures, this leads to increased wear on the back wall of the pump casing
The music is distracting. The parts on the white display(?) board show no individuality for identification. All the parts look the same. Perhaps this video was made mainly for professionals.

I have a Gould's submersible pump for the water for inside my house. It's an older one an old.man gave me. He said it can be repaired. The motor runs strong , but the fans or impeller dosent work. Can that be replaced since being the Gould's are so expensive and I need a pump for inside my house because mine quite working.
My cartridge seal is on a sleeve from new. Similar to this one in the video but has a sleeve in the center of cartridge and does not fit on shaft... do I have to remove the sleeve?
Not sure who else to ask but you seem very knowledgable. I'm using a 10" Gorman Rupp self priming prime air pump in a creek that has a huge pool area that I'm pumping out of. The pump primes itself easily but when losing prime, it cannot reprise itself. We've done this many times but never had this problem. The pump will actually pull the water right up to the pump but won't pump. Any suggestions?
A couple of things could happen here: Discharge check valve worn out. Check valve on ventury line collapse. Suction pipe had a hole in it. Float on the priming chamber is unscrew . Piping from compressor to the priming chamber is worn out.
For AC centrifugal pump with a fixed power supply frequency (eg. 50 Hz), if the NPSH required is achieved, is the flow rate constant? Is the liquid flow rate at the rated flow rate on the nameplate?
