With setup and programming fees, new cartridges, cores, core cleanup, etc. its not cost effective - at least here in SoCal. I've researched it and given that the total sales will be 50 units over 5 y

One day and nearly sold out... that is demand alright!

I have yet to actually find a LD28 water pump for sale new anywhere. And I actually owned the Maxima that I needed one for. If you can find real LD28 water pumps please pm me the details after you get what you need. I kick myself for tossing a bunch of them in the recycling. I hate it when I do that.

John, RE: Impellers

 

If you get the sourcing worked out, perhaps buying 'bearing and seal cartridges' from the same source as the bulk reman shops do is a good plan for an 'upgrade kit'...

 

Basically make the impeller a shrink-on item, and people can take their old bearing housings, drop out the old impeller/bearing/seal package and refit the new items. This is the direction JeffP and I were going. Plenty of gas engine cores out there, but you want a new bearing and seal package to go with that new impeller.

 

If it's cast or even steel, a powder coat, or Techline heavy coat of abradable paint would work well to seal up impeller to casing tolerances as well... I think grooving the tips of the impellers and fitting a teflon wiper is going a bit far...

That is the downfall of leaving the last company---they had a CMM and Five-Axis capabilities in-house. And PLENTY of apprentices that needed to do programming and setup. All I would have to pay for is the stock. Damn MBA's and their 'no touch parts operation' visions (that fail miserably...) :angry:

 

 

Keep in mind E-Pumps are constant flow for the most part. Unless you have one of the fancy models from Europe that has variable flow / variable speed. The question becomes "at which load point is the flow correct" with an E-Pump. How do you compensate for overcapacity (if it exists) at idle, if sized for maximum load. What happens if flow is lower than expected at full load? :(

Anyone have pictures of the two water pumps?

 

Like JohnC said, my local dealer says they have the LD28 pump in stock. I would like to have a visual reference so when I have to return it there isn't much left to question.

 

Joe - we have to check your parts box this weekend. I didn't even think to open it yesterday when I wrote down the part number.

The LD28 pump impeller is far from not being cost-effective.

 

Do it the same way everyone else does; cut it from a casting. Cast, wheelabrade, collet chuck, face, turn, bore, done.

 

Total manufacture time can be less than 20 minutes from a hot melt. The problem is getting someone to stop the more lucrative work they are already doing, to setup to do your smaller, faster job.

I've researched it and given that the total sales will be 50 units over 5 years (if I'm really lucky), it just doesn't' work out. Secondly, tying my money up in 50 parts for years doesn't make business sense.
