Schwing Used Concrete Pump FAQ: What I Learned From Costly Mistakes

Schwing Used Concrete Pump FAQ: What I Learned From Costly Mistakes

I've been managing a fleet of concrete pumps for about eight years (maybe nine, I'd have to check my records). In that time, I've personally made—and documented—at least a dozen significant mistakes that added up to roughly $300,000 in wasted budget. Now I maintain our team's buying checklist. These are the questions I wish someone had answered for me before I started.

Where can I find used Schwing concrete pumps for sale?

The usual channels: Machinery Trader, Rock & Dirt, and Schwing's own dealer network (Schwing America has a used equipment section). I've also had luck on specialized forums. But here's the thing—around 60% of the listings I've seen online are from brokers, not the actual seller. (Should mention: always ask for the VIN or serial number and run it through Schwing's parts database to verify the year and configuration.)

What should I check before buying a used Schwing concrete pump?

Start with the rock valve—that's Schwing's signature technology. Check the wear plates, cutting ring, and the S-tube. People assume the pump's age is the main factor. From the outside, a 2015 model with 5,000 hours looks similar to a 2020 with 8,000 hours. The reality is that maintenance history matters far more than hours or year. I once bought a 'low-hour' P88 that turned out to have been run with contaminated hydraulic oil—the entire pump was a ticking time bomb. Cost me $22,000 in repairs. To be fair, the dealer disclosed it after I pressed them, but I trusted the low hours at first glance.

Also inspect the truck chassis itself. A concrete pump truck is only as good as the truck it's mounted on. Check for rust on the frame, especially around the pto and hydraulic tank mounts. I should add that you want to see service records for the truck as well—not just the pump unit.

How much does a used Schwing concrete pump truck cost?

Prices vary wildly. A 36m boom truck from around 2012 with under 5,000 hours might be $150,000–$200,000. A P88 trailer pump could be $30,000–$60,000 depending on condition. I've seen dealers ask $250,000 for a well-maintained 58m truck from 2018. (These are ballpark numbers based on what I've tracked over the past 18 months; verify current pricing with multiple sources.)

Are older models like the P88 still worth buying?

This was a hard lesson. The P88 is legendary for reliability, but parts availability is decreasing. Schwing still supports it, but some components—like the original boom remote—are getting harder to find. I have mixed feelings about buying a P88 today. On one hand, they're built like tanks and can run forever if maintained. On the other, you might spend weeks chasing a hose fitting that's discontinued. My compromise: buy a P88 only if you have a competent local hydraulic shop and are comfortable sourcing parts from surplus dealers. This worked for us, but our situation was we have a full-time mechanic. Your mileage may vary if you rely on dealer support for everything.

What's the biggest mistake people make when buying used?

Hands down: ignoring the total cost of ownership. That $200 savings on a 'cheaper' unit turned into a $1,500 problem when the wear plates needed replacement after 200 hours instead of 500. I've seen buyers go for the lowest quote on a used pump truck, only to spend $18,000 on a new outrigger system because the original one was corroded. (Note to self: we documented 47 such cases in our fleet over two years.)

The 'cheapest option' thinking comes from an era when pumps were simpler and less instrumented. That's changed. Modern Schwing pumps have complex electronics, and a broken joystick controller can cost $800–$1,200. Always factor in a professional inspection before purchase—spend $1,500 now to avoid $15,000 later.

How do I verify parts compatibility for an older pump?

Go straight to the source. According to Schwing's parts lookup system (schwing.com/parts), you need the serial number to get accurate cross-references. I once ordered a set of wear plates for a 1999 model based on the year alone—turned out the pump had been retrofitted with a later-style valve. That mistake cost $890 in redo plus a 1-week delay. (Should mention: call Schwing's parts line direct; the online tool is good but a human can catch serial discrepancies.)

Oh, and one more thing: if you're comparing buying a used Schwing pump truck to buying a box truck for other uses, stop. A concrete pump truck is a specialty vehicle with high maintenance demands. The calculation is completely different. In fact, I'd say buying a used concrete pump without understanding this is like thinking you're smarter than a fifth grader at math—you'll quickly realize you're missing basic facts. Take the time to learn the machine.

Final thought–keep perspective

Buying a used Schwing pump done right can save you 30–50% vs. new. But the savings vanish if you skip the homework. My checklist now includes: verify serial with Schwing, inspect rock valve and wear parts, check truck chassis for rust, get a professional inspection, and calculate total cost including immediate repairs. I get why people go for the cheapest used unit—budgets are real. But the hidden costs add up. That's my two cents from the school of hard knocks.
