Mechanical Seal Repair on a Goulds MCC Series Pump 

My pump was apart for a week or 2 then I ordered the correct parts. Took 3 weeks after that to get a new ceramic shaft seal, spring etc... . Thanks for showing how it all goes together. By the time the parts got here, I forgot.

Thanks, you helped me replace the seal on a much bigger water pump. Never done it before :).

Great video!

Replacing seals on a 5hp pump tomorrow. Your video helped give me some confidence. RU-vid University! Thanks!

nice tutorial it helps a lot

Thanks young man

Hey Chris! Like usual your videos are awesomely terrific! Can you pretty please do a video on how a Venturi (or jet valve located inside the well) of a two pipe well system works? This system uses a jet pump. Inquiring minds want to know. :)

Good video..👍

Do a no load run on the motor. If it isn’t butter smooth and quiet then you need to be figuring out which bearing is bad. If it is smooth and quiet then put the pump back together. But if the motor has a bad bearing it will ruin the seal fairly quickly.

Very nice and good . I 💕 your video. and you?

I have a Gould JRS7 and it has a flat head screw instead of a bolt where the propeller is… I am having the hardest time trying to get it off. It’s ridiculous. Any tips for that particular style?

i have the same issue with Pedrollo water pump ... it starts leaking water and had awful and noisy sound, thnx for the video

our J10S does not leak, new impleller, doesn't appear to pump water from one bucket of water to the other bucket of water How to determine why???

That nut on the impeller is always striped out a spanner wrench works the best just hope the shaft is okay if it's bad it will still leak. the white ceramic It best to silicone the rubber in cheap insurance. lube the seal with soap most likely it for drinking water. when pushed on make sure the seal dose not roll or it will also leak of course keep clean the most common reason it brake like that is from air hammering from a air pocket the impeller being unbalanced/bent wouldn't brake the seal it would have to be bent really bad and if that was the case it would most likely lock the pump end up right away first. Ps. I've been building pumps and booster for way to long it seems like now 17years so I think I done quit a bit of them. for 8 year at least 99 percent of the boosters that have come to our shop have been done by me the only time I have a problem is when the seal is cheap or low quality. I would always pick the highest quality seal if you don't want any leaks. My opinion👍👌✌️💯🥂💦🌊⛲

What is the maximum psi that this type of pump can generate and run at? On a system with a expansion tank.

Put a dial indicator on motor shaft will tell you real quick if it's out.

Hey brother, just curious why you didn't show how you removed the front housing from the seal housing...if yours just simply pulled apart, that's awesome. I've never seen the cast iron housing separate easily from the stainless steel housing without using a homemade bearing puller tool. The water is pretty hard and/or corrosive in the high desert where i live and was just curious if you used any technique to separate the housing or not. Thanks, Justin Henry

I have a Gould J7 that came with my house. I noticed a decrease in pressure and started troubleshooting with your videos and noticed that the motor was set to 230 and there is only 115 that it has been running off of. Is the damage down or would wiring it correctly help to fix the problem?

I actually wanted to see the water test

Hello Where can we find in the Philippines, spare parts for the gould model J5S pump. photo attached. Thanks for your feedback Best regards.

hi buddy ive got a Goulds 1 H.P 2 stage jet pump mounted above ground the well is about 150FT deep im having a hard time finding parts every one wants to sell the whole pump and i have a new motor on it just need to rebuild the pump part leaky seals & o rings ni might as well change the 2 impellers can you help me in any way ? i thank you very much sir .

Why don’t you go with tungsten seals, I work on t-30,t-60, and t-75 rossi and catteli circulation pumps and tungsten material seals seem to work better

It can be lost the prime because of that seal?

How long do the seals last more or less?

Ever hear of an impact wrench?

You put the seal in backwards, that’s why you got movement.

Are there any USA pump Companies left in the USA?

Please help me... I have need to leo Ajm75 pump repair Videos

Hi .where can buy a pump parts .?

Why big box, USPS will choke hold it and body slam it just like the cops if it was in a smaller box!

Why did you skip part of the rebuild watched the first video and then you go to this what about the stuff I'm the pump hosing

Need illustration to be on the j15s &not the j10s they are built differently

Changing a seal but not bearings is like wiping before you poop. The seal doesn’t hold the shaft straight. Time will not tell. You me issue is already clear and should be fixed.
