Something not quite right?
Let us make it perfect.

Our full-service pump shop can do just about anything. We’re fast and flexible. And if you’re ordering the parts from us, most times we’ll do the work for free!

Part Swap/Upgrade

Packaging (w/Gear, Motor etc.)

PS: We also offer pump repair and rebuild services including no-obligation estimates and free shipping!

Alright you got us, this isn’t actually one of our pump mechanics, our guys are much larger than their wrenches

We’re going to make this really easy on you.

Pumps and process equipment can be complicated, and buying online even more so... that’s why we work to take the risk off you. Every item we sell is covered by our Triple Promise Warranty:

#1: We Don't Sell Junk

Many of the pumps and parts we sell are surplus, rebuilt, aftermarket, used etc. but we’re no surplus or salvage yard! Every single item on this site has been closely evaluated by our shop team. We carefully measure tolerances and overall item quality to ensure performance and reliability.

#2: Easy (and Free) Returns

You can change your mind, and return any in-stock item in the same condition as it was received, for a full refund of the purchase price. No restocking fees, no hassles. If it was our mistake, we’ll even refund the shipping! Want to return after using the item? See next pomise...

#3: Minimum 1-Year Warranty

Like we said above, we don’t sell junk. If it’s listed for sale on PumpRack.com, regardless of the condition or grade, we will provide a full parts and labor warranty for at least 1-year from the time of purchase. For Viking® aftermarket pumps and parts, we extend that to 2-years. And for our Rebuilt Pumps, we extend to 3-years!

PS: We have a formal statement of warranty for easy download and printing, if you’re into that sort of thing.

Ok, this might be a bit dramatic, but we really wanted it to be clear that we’ve got your back

Always know exactly what you’re buying.

Not all surplus pumps and parts were created equal. And things get really complicated when we talk about “used” equipment, so our attempt to make things simpler is this simple chart.

In total there are four Condition levels, each with it’s own A, B or C grading scores:

Hmm... In hindsight, this system seems like a good idea

Factory New (also "New")

Brand new, purchased directly from original manufacture.


Perfect, factory-fresh. Still new in box. Most times includes original factory warranty.


All ‘Factory New’ items are A-Grade.


All ‘Factory New’ items are A-Grade.

New Surplus (also "Surplus")

Unused/Never placed into service factory overruns, liquidations etc.


Near perfect, factory like new condition. Little to no shelf wear, or cosmetic issues. Flawless performance.


Excellent condition with light to moderate shelf wear or cosmetic issues. Flawless performance.


Good condition with moderate to heavy shelf wear. Might require very minor parts replacement or servicing.

Rebuilt (also "Re-manufactured")

Torn down, cleaned, evaluated. Worn parts replaced, ready to go.


Perfect or near perfect, factory like-new condition. Fully restored to original (or better) factory tolerances and performance.


All ‘Rebuilt’ items are A-Grade.


All ‘Rebuilt’ items are A-Grade.


Previously in service, still usable/within factory tolerances.


Excellent condition functionally and cosmetically, very light use and/or noticeable wear.


Good condition functionally but might have some cosmetic issues and visible wear from light to moderate use.
