How to dismantle and assemble Grundfos MQ pump

[@surffancy]

Great repair helping video. It helped a lot to reassamble my pump.

[@sergius4615]

video is right on time: my pump has gulped some sand+clay from the river bottom. Disassembled, cleaned - now works as new in spite of 12 years' age. Good job Grundfos!

[@monerradmanalimonerradmana9285]

Thank for the video

[@pulodogato3888]

Muito bom vídeo 🇧🇷🎯

[@veroniballet6232]

Thank you for the informative video! I broke off the vent cap while trying to vent the pump. Can you advice a spare part number for this? And perhaps a tip on how to remove the part that is still in the pump? Thanks in advance!

[@grundfos]

Hi Veroni, Glad you liked the video! Please have a look here, and see if the broken cap is part of this kit: grundfos.to/3NStdtt Otherwise here is a link to all the service parts we offer for the MQ pumps: grundfos.to/3mHzHiV Regarding the extraction of the defective part, please use a pair of pointed pliers, or a screw extractor. I hope this can help you out. Kind regards, Sabrina

Why can't I find a replacement for the pressure tank? Mine is full of water. Would that explain my terrible water pressure?

My pump is leaking pretty heavily from the bottom it seems would I be better to get a rebuilt gasket kit for Purchase the Scala 2 ? I am afraid to purchase a new pump for the price and have an issue with it as well.

[@grundfos]

Hi, I am sorry to hear that you are experiencing an issue with your pump. May I ask where you are located and where you bought your pump? Kind regards, Sofie

[@walkingwater893]

Great video, but we are unable to troubleshoot our problem. Is an oldish MQ and it is stopping after approx 1/2 gal and start again when drawing water. Then it will turn on frequently with no taps on. However then it will go for hrs and not turn on by self. I hope we can repair rather than purchase another unit. S. Colorado Suggestions please.

Hi, does The mq3-35 have a built în presure reductor?

[@grundfos]

Hi Mitrut A, Thanks for your interest. No, the MQ3-35 does not have a built in pressure reductor. Have a nice day. Regards, Susan

[@guyspencer4322]

We have a MQ3-45 that is approximately 10 years old. The pump is running constantly but does not create pressure, we have checked for leaks and have found none. Can the pump be fixed?

[@grundfos]

Hi Guy, thanks for contacting us. That is very difficult to say without more information. Can you give me more details of your location and we can see how is best to help you, thanks and regards Jackie

[@guyspencer4322]

@@grundfos sorry it took so long for me to get back to you. It turns out I was the problem not the pump. I had the wrong valve open and was trying to pressurize an open loop. closed the valve and the pump reached pressure and stopped. We are back in business. Its a great pump, its too bad you no longer make it.

[@grundfos]

Hi Guy, great to hear oyu are up and running again :-) Have a nice day, regards Jackie

[@thesetruths1404]

Hi. My 12 year old MQ3-45 pump is used to pump 1,000 gallons every 5 to 7 days. The pressure gauge is pressuring to about 70psi, stops like it should, and then leaks down over about 3 to 4 minutes to about 30psi, and kicks on to repressure. If there are no leaks anywhere, could this failure be the "internal non-return valve?" I only have one pressure gauge on the pump, and I do not have a pressure tank.

[@grundfos]

Hi again, I just replied to your comment on the other MQ video. Please have a look there. Thanks and have a lovely day! Kind regards, Sofie

[@thesetruths1404]

Hi. Ok. Thanks I look forward to your reply when the coworker gets back to you.

[@grundfos]

Hi again. Sorry for the delayed reply due to the weekend. :) As there is pressure loss it could actually be anywhere in the piping, and yes, it might be the non return valve not closing tight. But to be able to clarify and resolve your issue, I would recommend you to contact your local service center. You can find an overview and contact details here: gfos.ly/6051TyRpP Let me know if you have other questions. Have a great day Kind regards, Sofie
