20 Most Recent Tsurumi Pump s Submersible Trash Pump - 3000 GPH, 1/2 HP, 2in., Model# HS2.4 Questions & Answers

You are right, it is not running since there is no water
that goes out. It is just humming - which be due to
stucked impeller or busted starting capacitor. Let's start with checking up the impeller. Unscrew the strainer, and take it off. At the suction port, try turning the impeller by your finger. This is to check if it is stucked. If it is stucked, open the bolt holding the impeller case, so that you can free the impeller from
being stucked. Once the impeller is free, you can assemble the pump and switch it on and make it run.
If it doesn't run, then the final touch is to replace the
starting capacitor at the topcase of trash pump. In
doing this, make sure that in the reassembly of the top case, you must maintain the right force to close
the top case bolts water tight. Just send you e-mail
for further assistance. God Bless you.

Check your power cable for any hole and damage, that might be the problem

if not
remove the 2 screw where the cable is connect on the pump, gently pull off the ruber from the cord and check if your 3 wire are wet ? and if any water can come out of the cable hole?
if yes you have to take most of the pump appart to make the stator and rotor get dry and also check for any black part on the stator, to make sure it not burn if you cant find any black spot on the part let it dry for a week and spray some air on the stator everyday and your problem will be fix,
At our big factory we use special oven to dry the part quicker

If you have no water that came out from the inside of the pump it has to be the power cable or your breaker the reason why the pump work fine when only the base is submerge is because the pump have less restriction (Water to push) so the engine work is very light compare when she is submerge and have to push so much water alll the way throught the hose.

I can help you if you need more info,

If the pump is fairly new it could be the starting capacitor,

But if the pump get really hot quick its the motor who is damage and need to be rebuild or replace,

how old is your pump and wich model do you have?

Seem like the motor overheating and the motor protector make the pump stop,


Check if there is any physical damage on it,

Is it a very old pump?

Hi Rob,

If it was the capacitor the pump should not start at all but if you know a electrician there is a way to verify if the capacitor is charge and/or recharge it with a ''UF'' tester

Check also if the power cable is damage or maybe was damage before and someone fix it with duck tape or anything else, and if the electric plug is very old and rusty, if so replace with a new one,

Other then that will have to check the motor and probably have to rebuilt it or replace it, when you changed the bearing did you notice any burn or damage part on the Stator?


Have a nice day

It should be connected to the red wire, and has to be completely inside the motor, inside the cable and this last, bolted properly on top, that is very important to prevent electrical shock or damage to the pump,

Have a good day,

Call your dealer they should have the cable there or www.tsurumipump.com 

 

have a great day,

Hi Don,

Thank you for your great explanation,

This pump really need some serious maintenance, this was cause because the mechanical seal broke down or was completely wear, check your warranty you have 2 years,

The overload jump because the pump at a motor failure, due to water,
The only way to repair this pump is to take the motor and rotor visually check if there is any burn spot or damage part if not you can try to make everything dry for a few days, replace the defect part and put it back together it might work (30%)

But if you think the electric motor run to long with water in it, It will be more worthed to replace it with a new one,


And i stongly suggest you to check the oil on your other pump, to know how is your mechanical seal,

To check the oil its the only star screw on the side of it, when you remove it try not to spill to much out, if the oil is completely clear your mecanical seal is fine, if its white like milk you need to replace it, it mean water start to infiltrate, and its worthed replacing it,

Hope i could help you let me know if you have more question,

Have a great day,


(mechanical seal is what prevent and block water to reach the electrical motor, its the part that as a big stainless steel spring with to sillicon face on top and bottom,)

Check with your dealer, they should have a power cord in stock or you can also check with Tsurumi they will fix you up,

Probably any bearing store will have the right one,but you will need a mechanical seal from a Tsurumi pump Distributor,


www.tsurumipump.com

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,

,

Bearings or bushings may be gone in the motor itself, or there may be something behind the impeller which is binding, pull the case/volute off and take a look for debris

sounds like something is maybe stuck in the pump causing this problem.

Mostly likely no.. These pumps have a sealed bearing that can not be serviced.

those pumps have a build in timer that runs every 30 secounds then shuts off, then if the pit isnt draind yet will kick on for 30 secounds.

As long as your sure it's getting proper voltage, then it most likely has a start capacitor built into pump circuit, that has gone faulty.
