reverse water pump

[gd71eb]

is there such a thing as a reverse rotation passanger dump small block water pump?

Good question. I've seen bi-directional pumps too, so that might help with compatibility. But you have to make sure that whatever pump might have that side inlet on it, also is compatible with the bolt-pattern of your existing front cover.

Are you running the stock front cover still?
I have a Ford Racing bi-directional pump I'll have to take a look at. I think it fits the stock cover, but don't remember what side the inlet is on.
Might take me awhile to find it though, so maybe a quick search of the Racing catalog will reveal it. Assuming they even still sell it that is.
They tend to drop things just as I get interested in them!

not sure

to be honest dirt i forgot what i got going on this thing. build was posponed due to lack of funds and i just now am starting to get back in it. although my automotive prowness is still very lacking. here is a photo of the cover, it has a dipstick tube on the pass side and mech fuel pump port

blocks a 72 windsor but not sure what the serp system came off or the timing cover. just threw stuff together not knowing about reverse this balance that...ect then bought a alum radiator to match it all up

Not a stock application.
Some aftermarket. Some are bi-directional but ask anyone who deals with pumps and you will quickly find that in order to be bi-directional there are compromises to performance.

how about

an electric water pump? are they good? dependable? any thoughts?

are there any that can supply heater hose outlets?

Great for drag racing, burst of heat, 30 minutes of leaving the engine off and let the pump and fan cool off the block. Repeat.

Think of this, if it was any good some manufacturer would have done it by now. Closest they have done is an intercooler circulating pump. Only a fraction of the flow needed to keep an engine cool.

Dependable? The mechanical water pump has very little in it. Bearing and a seal really. Electric has those parts and all the eletrical stuff to go with it. And unlike other eletrical things that have had millions of dollars invested in them by a manufacturer to make them reliable, the electric pumps are all aftermarket.

There are a few out there that might work. I have seen them at SEMA for years. Good ones are very expensive. And you can't get parts on a Friday evening.

All this can be fixed with an off the shelf reverse rotation waterpump and a crossover pipe. Any backwater town can get an off the shelf waterpump.
The crossover pipe has zero moving/wear parts so no worry there.

I have the same problem as you. Here is the water pump I think you need, it is passenger side dump and reverse flow. This will also work with the 9 bolt timing cover you have. You can order them from Summit or Jegs in chrome, the black powder coat is back ordered for 2 months.

I should have this exact pump sitting on my door step this afternoon.

^What are the applications where you need this? Is this for Mustang or Explorer serp type of setups where you want to keep the original radiator?

In my application I am using it for a serpentine system from a truck. The timing cover I have is for the old style standard rotation water pump with 9 bolts to mount it. The off the shelf reverse rotation water pump bolts up different and the water ports are a different off set. I found that out when I bought a reverse rotation water pump and it wouldn't fit right.

WOW coscag00 i thought all hope was lost ..... very cool find.
funny thing is i searched both summit and jegs and missed this in both sites:-[

The housing on the pump is exactly the same as the regular flow water pump. The flow of water does not change from a regular flow vs. reverse flow, what changes is the impeller on the pump. Remember the serpentine system turns the pump counter clockwise so the reverse impeller has to be opposite of that to get the water to flow the correct way.

Hope that makes sense, at least that's how I understand it.

Will post pictures when I get the pump.

B C Broncos has a heavy duty pump that fits the stock location with the passenger side connection and flows either way. I converted my stock pulleys to serpentine and use one for 8 years without a problem. I think it is made for marine engines because it has a big brass or bronze impeller.

Here are pictures of my pump I just had delivered.

 

[gd71eb]

WOOT pictures!!! gonna do a comparison now

fingers crossed

ok it is defenetly different blade config then the one i got. however i still wonder how water is "forced down" the passanger side as the casting is the same as i have. your photo looks like the blades will just push the water passed the milled out slot instead of into it. again i am not an expert by no means so please dont take offense just trying to understand the way it works.
I REALLY REALLY want this to be my fix as it will save tons of money in buying a bunch of new parts including the alum radiator.

 

[COSCAG00]

Give Tuff Stuff a call Monday and see what they say maybe they can explain it to you. If you get an answer tell us because I can see what you are saying about the water. I think the blades suck the water from each side and push it out the middle out the outlet to the radiator.

From the searches I did BC Broncos water pump also comes from Tuff Stuff but not sure what model or if it made specially for them.

That looks like a standard rotation waterpump.
The flow off the impeller isn't a pure radial flow. There is rotation on the shafts axis. the channels that catch the water as it is spun off the impeller look to be set to catch the flow of a standard rotation water pump.

The impeller even favors standard rotation with the way the vanes are folded. The flat of the impeller catches the water better. Now the straight vane is purely bi-directional.

 

[COSCAG00]

Guess I will find out eventually. The part number is 1432CREV which translates to a reverse water pump with chrome plating. The standard rotation water pump is just 1432C.

Have a stock reverse rotation water pump I can compare to. Will take a look and let y'all know.

 

[COSCAG00]

Ok had to go take a look and compare the pumps. I have an old pump that I am positive is reverse rotation that came off of the truck serpentine system and it's impeller is exactly like my new pump.

So they are both reverse rotation. I also called and talked with Tuff Stuff a few weeks ago and explained my set up and this is the pump that was recommended.

Unless I'm going completely dislexic, that is a regular rotation pump. The impeller is meant to spin clockwise (looking from the front) same as the crank pully. The water pump is a centrigugal pump that slings water from the middle of the impeller (radiator inlet) to the outside vanes. The timing cover water ports are directioan as well (usually) so you can't just swap the pump (usually).

Here is a quick litmus test - does the standard rotation pully bolt straght up to the pump? If so it's the wrong part. Standard and reverse rotation pumps have differnt pully bolt patterns.
