Restoring Pumps with a Hi Flow Impeller

If you are interested in a rebuild you are probably (A) restoring a numbers-matching car or (B) cannot find a new pump anywhere and either want a conventional pump or have experienced the benefits of hi flow. We have been helping restorers for 40 years in the construction of our radiators so it was an easy decision to use our hi flow impellers designs for numbers-matching cars and unavailable castings. What’s the process?
Step 1: Notify us that you have a pump and what it fits
Step 2: Send us the pump and the timing chain cover if it is available
Step 3: We’ll receive the pump and inspect the casting and impeller

There are 3 scenarios we commonly see

A. The casting volute, diameter, depth, angle and rotational direction match an existing pump impeller

B. The casting volute, diameter, depth, angle and rotational direction is close to an existing pump impeller but requires some modification

C. Nothing matches an existing pump and we have to design from scratch

Step 4: We call you with information and a ballpark estimate of the cost to create a hi flow impeller for your pump. At this point, you move on to the next step or we just return your pump to you.
Step 5: If we proceed with a re-build, we'll ship your pump to a specialist that dismantles, cleans and installs new bearings and seals. We use this company because they're experienced with dismantling fragile castings and can create bearings on site that may take us weeks to source. They are fair, honest and have a quick turn-around.
Step 6: The pump is returned to us and we install or modify or design a bespoke impeller and then install the impeller.

What’s the cost?
Obviously it ranges but the costs for the first scenario described have been tracking 249.  Modifying can be 60-200 more. Designing a one-off bespoke impeller costs a little more.  After digitizing the volute, drawing the model, procuring vice jaws, programming CNCs, machining a batch of one unit the cost can approach 700-1,000.

We do not undertake any work on your behalf without your consent and your exposure is always limited to the cost of the freight.  If the costs are too much for your wallet to bear we can simple rebuild your pump with new bearings and seals and reinstall the original impeller.

Isn't there a way to get the cost down? Absolutely - volume. The more people that need the same application, the more we can divide out the costs of design, drawing, programming, set-up, materials and machining time.  If we hear a common request, we’ll keep the customer names and when we get to reasonable “batch”, we’ll contact all interested parties and they can buy together.  We can work with clubs and specialty catalogs.  If we determine there is a market, we'll even subsidize the development costs of the impeller.

Can't you sell me a kit? We do not sell a kit.
