being that this us a sump pump that goes in the water you need to take it to a pump rebuilding company. so that new seal are put in. I would never do a repair even on a cord to a sump pump for that reasonl. Never what to know that I made a mistake that killed someone.

Please take the pump to a company that does that. Look in the old fashion yellow pages or on line for someone close to you

Thanks and be safe

Tsurumi pump 40pu2.15s my pump only humming and stop pumping water. what is the cause?

Most likely cause is a blocked impeller. Disconnect from power supply, remove pump from sump, take off pump base to expose impeller and check for freedom of rotation. If all appears OK and pump still just hums it could be a blown capacitor - unless you really know what you are doing I suggest you employ an experienced expert to proceed further. Where are you located?

Is the internal motor in a tsurumi 50pu2-15s

No it should be completely dry and clean, check the date of purchase, you will need to replace the mechanical seal and clean the motor,its not suppose to happen,

ask your tsurumi distributor if you want to repair it or ask about the warranty, i am assuming that the pump stop working so thats why you open it and ask about it here, make sure you dont see any burn (black) wire on the stator, if you see any burn on the stator its a bad news,

If there is no burn part,
If you have just a few dip of oil in the motor try to remove the oil as much as you can with (electric part (brake) cleaner) or rag and replace the mechanical seal,

If there is a lot of oil all over in the motor, if he is not already damage (Burn),you can try to wash the motor with clean or light soapy water and then let him dry for a few days or in a oven to make sure all the water is evaporate, then replace the seal and cross your finger,we can never be sure that this procedure will work due to this small electric motor, and you never know how long the motor might have run with liquid in it, but i say its 51% succesfull chance to work, if you have to pay someone to do that it might be worthed to buy a new unit.

Hope i help you,

Tsurumi submersible vancs series pond pump has

To get a new owner manual send them an email and they will email or send you one,

Is the pump was working fine for a long time before that happen?
if yes
There is a motor problem,
You can check your pump power cable try to find any damage or hole in it.
If the cable fine
And if the impeller and wheel still turn before triping the breaker It would be a good thing to check the amperage with a special electronic tool to see how much amperage the pump take,
if you are good in manipulating tool we can send you the breakdown or i can support you to open it and to check the motor trying to find any burn part in it. That way we will know right away if its worth to fix it.

let me know

If your repair cost is more than 50% of buying a new unit, it is advisable to buy another. God bless you.
