OEM Surplus Parts

RSI employs several active spotters/buyers across the US and Canada. Because of this, we can offer a large supply of surplus OEM pumps and pump parts.
All parts are inspected at site of purchase before final purchase is made.
You can rest assured that all RSI surplus offerings meet OEM specifications for form, fit & function.


RSI has numerous options for keeping you supplied with low-cost aftermarket parts. We can offer the same quality as ANSI B73.1 OEM in a variety of alloys.
We've reverse engineered shafts and sleeves for most ANSI centrifugal pumps (as well as a multitude of other pumping systems), adding more all of the time.
We can supply all of your seals, gaskets, o-rings, bearings and misc. hardware in multiple materials.
