Flojet pumps. .

[Able 1]

I have been having problems with my pump over heating it says:

So I took out my accumulator tank and it still over heats.. Is it just the wrong pump for the prochem water box or what is going on here? It's OK for a while but it I have bigger jobs it shuts off due to high temps..

What model is it?

[Able 1]

I first replace the switch(normally it goes) then the pump, to no avail. .

 

[Able 1]

I switched pumps with my other TM and that one is fine.. Not sure why these run too much..

 

[dgardner]

I imagine your water box valve cycles the pump often enough to overheat it on long jobs. The pressure switch is rated for only so many cycles as well. You might consider one of the newer VSD pumps. They use a pressure sensor and variable speed instead of a pressure switch. The Flojet R4515 743A is a good match to your specs:

tell me again why you guys need these pumps....?

 

[Papa John]

we use them to transfer water from our water tanks to the TM.. we carry our own water-- no need to find water source at each job.. If a custy is a pain-- Ill fill up my holding tanks at their house

Because the pressure pump is mounted up high and Newton's law of gravity says water won't go up hill without help.

So would you still need the tank?

 

[dgardner]

The accumulator? No. Flojet says it is not needed with this pump.

but Richard....why not jus use a pump that is strong enough to pull water from the tank itsef........
CRASH pulls his water from the passenger side all the way up and across the ceiling of the van cuz he don want to have the hose on the floor of the van......

What is that a wanner Hydra Cell?

 

[bob vawter]

yepper

 

[Desk Jockey]

So why is it that only Steam Genies used them?

 

[GeneMiller]

Max pressure is to low on the hydra cell. Limit is 1000 psi. Flow is really high. You have to jump to a much more expensive one for higher pressure.

Keith I always hated the pump problem. I solved it by using a halwin shutoff switch in the water tank. Zero problems after that. Best decision ever. Also make sure you go a size larger on the wire. Can't hurt

I used a transfer pump for a couple of years...like 4 of them.

Enough! Now I no longer need them. A little engineering manufacturers should better address.

 

[Able 1]

I never had pump problems before this.. I think I just bought the wrong pump.

I agree with you Gene, I think it has to due to the toilet type valve that leaks when you use any water... It needs to shut off and have some time before it starts up again. I think it runs non stop when we are cleaning. .

 

[wilpath]

the flow rate is not enough, pump cant keep up with your flow. get a 4.9 gpm pump, look at shuflo

god i loved those Steam Genies

What did you do?

 

[Lee Stockwell]

I put the pump below the fresh water tank, and enlarged fitting and hoses feeding the pump to avoid cavitation.

That's a point I'll think about, the pump that is working good is a 4.5gpm Flojet. . Though I don't use 3.3gpm it might be over working it..

No water box?

 

[GeneMiller]

It's the chattering that happens when the water starts to shut off. It needs to be a hard stop of water to prevent it. The floats being used are for a garden hose not a demand pump. The chattering is hard on switches and causes heat build up. The halwin switch has a 6" swing and only turns on when the tank is 3" from empty and stays on until it's 2" from the top. The pump never cycles or chatters again. I would direct feed it if the water box was on the bottom. I'll be back in the pump buying business with the 870. I'm not gonna pop a hole in the stainless box. Wouldn't work anyway. Can't wait to try out the new style pump. Thanks Dan didn't know that pump existed.
