Water pump question

[Wayne M.]

It had a coolant leak between the oil filter housing and the block, so it's getting that and the pump. No coolers, they reneged. Only 2000 hours. It's a short haul delivery.*

 

[gsbrockman]

There have been members swapping the worn out stock pump for a pump with plastic impellers or to simply have a spare on hand. Many times these plastic impellers were in pieces in the box. If i remember correctly Brockman was one who found such damage. Is the plastic to resist corrosion of coolant or such? I for one will like a pump without plastic which is prone to shipping breakage.

That is correct, Herzog. When my water pump went out in Huntsville, AL, since the nearest dealer did not have a water pump in stock, I sourced a Murray Temperature Control unit from a Pep Boys. I asked my service writer if he verified the water pump gasket was in the box, and he had not checked. He handed the box to me, and the gasket was there, along with three of the seven blades broken off.....lying inside the box.

Well obviously whatever material the impeller is made of, it's subject to breaking the impeller during shipping. That's not acceptable! Still my question remains. Why does the pump impeller on my original post look different than most others I've seen? Is this their latest, greatest or a knock off Cummins OEM pump?? gsbrockman, I'm curious how many miles you got on your original pump. I'm still debating changing mine out with 93K on the clock, since I have to change coolant soon.

My theory... the pump's impeller design has changed to include the ring around the blades to add rigidity and strength to the plastic impeller in order to prevent prevent the impeller blades from breaking during shipping !!!*

 

[Sleeper1]

Now you're thinking like an Engineer, have to keep the part intact during shipping, so that it can fail in the application and cause more damage! Engineering 101 on how to keep your job. Honestly as long as the flow rate is close to the same, I prefer to see the impeller fins with the ring helping hold them together. Thanks for the laugh

 

[Bob4x4]

IMHO that impeller design is to reduce cavitation-not so much physical strength

 

[Sleeper1]

I agree Bob. Bob, would you recommend pulling the pump and checking it out while the coolant is out or could that possibly cause the seal to leak?? I think I'll keep the original in and hold on to the "new" for whenever it decides to fail.

 

[Bob4x4]

Not much you can tell by pulling it out,if you do have an extra seal on hand,It will be very flat,I wouldn't want to risk reusing it

 

[Bob4x4]

Forgot to add,be sure to bleed the system.There is a hex plug to pull.Air in the system can lead to egr cooler failure

That is golden. Can you give a location or post a pic?*

As I mentioned before, my issue with the plastic impeller is that they tend to slip on the shaft. Whatever attaching method is inadequate in the application I see this happening on.*

 

[Bob4x4]

The plug is in the coolant tube on a riser that runs next to the egr bypass assy on the passenger side of the engine

94,914 miles when mine went bye-bye

Jegs has a billet anodized pump with aluminum impeller for 239.99

Although we put an electric pump on my Son's shoe box Nova (it only has to run 11 seconds at a time) I don't think I would go that rout on a Cummins
daily driver

I was referring to their manual pump not the electric one, the manual one is 239.99

my 2010 3500 ate pumps every 60k miles like clockwork.. one at 60, nuther at 121k.. traded it at 172k for new '16.. everytime was a leak from shaft seal, blew coolant everywhere -j

 

[TCDiesel]

The CP3 seals are the same way @ 250-300K they leak Fuel into the front of engine like clock work ,We tell every High mileage owner to Freshen up the CP3 at the 250-300K mile range and with continue and proper maintenance 1 Million miles can be achieved. 60K is way to early...Coolant or belt stress?

 

[Regcabguy]

I have a spare water pump and somehow misplaced the seal/gasket. Is there a source for this?
Thank you.

Sorry guys, got busy at work and forgot about posting more pics. Here is a pic of one of the other WP's. Also, I finally got a reply from Concentric. I put an arrow on this pic to point out the insert he's talking about.

Dear Sir,

I have tried to check this and cannot track the part number, I assume it is a Concentric product.

We do not make an aluminium impeller for them but we do make composite. You should be able to tell by the presence of an insert.

Flow performance is likely to be the reason.

Best regards,

Paul Evans
