Want to save a bit of money on a new RPD pump? Try refurbished! They are still warrantied for a year like any of our new pumps.

You may be wondering what "refurbished" means in this case. Here's the scoop: Did you know that RPD pump heads like those made by Waukesha & Ampco wear down over time? It's true. Because there's constant metal-on-metal contact inside the pump head, the surfaces eventually wear out against each other. Once this happens the pump will still work, but not as well. It won't pull suction as well, flow rates won't be as high, and there may be more slippage internally. That's when it's time to have it remanufactured.

Remanufactured pumps are completely disassembled. All surfaces are re-machined and polished, and new components are installed. Shafts, bearings, seals, and gears are all replaced with new components. The pump heads are machined to their first oversize spec, and new rotors are installed. The pump is then tested and ready for sale.

Since Waukesha Universal 1, Ampco ZP1, and Wright Flow heads are all dimensionally and part-for-part identical, you will end up with one of the above heads in like-new condition at about 10% lower cost. So, same pump, same performance, same warranty, and all new internally. What's not to like?

Contact us for pricing and availability, as inventory is constantly changing. In general you can expect prices to be about 10% lower than normal prices on our Ampco ZP1 series pumps.
