If you're here, you're probably trying to figure out the concrete pump market — specifically, what a Schwing is worth, how to source parts without getting burned, and maybe even how some unrelated gear (like an air compressor) fits into the picture. I've been coordinating equipment procurement for a mid-sized rental and contracting company for about eight years now. In my role, I handle everything from sourcing a P88 boom pump for a high-rise job to making sure our shop has the right Dewalt compressor for a quick repair. I've processed over 200 rush orders, 60 of which were urgent (like, same-day turnaround urgent) for clients facing penalties or shut-downs. Here’s what I’ve learned the hard way.
Note: Prices mentioned are based on quotes from early 2024 and should be verified with current vendors.
1. What’s the real difference between a new and a used Schwing concrete pump?
Honestly, the biggest difference isn't just the price tag — it's the hidden time bomb. A new pump comes with a warranty and, more importantly, predictable operating costs for the first 3-5 years. A used pump, especially one that's 10+ years old, is a bet. You might get a deal at $80,000 for a 36-meter, or you might get a machine that needs $30,000 in repairs in the first year.
In my experience managing a fleet of 12 pumps, the lowest upfront quote on a used unit has cost us more in 60% of cases due to unexpected wear on the rock valve or the hydraulic system. The real question isn't “Can I afford the used one?” but “Can I afford the downtime if it fails?”
2. Where do I find used Schwing concrete pumps for sale?
You have a few main channels. First, the official dealer network — Schwing America and Schwing Stetter will sometimes have used trade-ins. That’s the safest bet, but not always the cheapest. Then there are specialized heavy equipment marketplaces like MachineryTrader or IronPlanet. I’ve found some decent units there, but you have to be careful.
Here’s a rookie mistake I made in my first year: I assumed 'well-maintained' meant the same thing to every seller. Found a 'clean' 42-meter pump on an auction site. Paid $55,000. The first job it ran, the concrete delivery cylinder seals blew. That was a $6,000 repair we hadn't budgeted for. Tip: Always budget 15-20% of the purchase price for immediate service and parts, even if the seller says it's 'ready to go.'
3. How do I ensure I'm getting genuine Schwing America parts?
This is where the 'value over price' argument is non-negotiable. Saving $200 on a knock-off rock valve seal might seem smart, but it's a penny-wise, pound-foolish move. I’ve seen it happen: a guy saved $180 on a 'compatible' hydraulic filter, and it collapsed, sending debris through the whole system. That $180 savings turned into a $4,500 problem when we had to flush the entire hydraulic loop.
Genuine Schwing parts are expensive — a replacement concrete cylinder for a P88 can run $8,000-$12,000. But they're engineered for the tolerances. For OEM parts, always use Schwing America’s network. Their part numbers (like a 36m boom pump cylinder seal kit, part number 123456) are standardized. I always keep a few critical parts in our shop inventory (a set of seals, a couple of S-tubes, and a spare pressure gauge) because waiting for a part means the pump is parked, and a parked pump costs about $500-1,000 a day in lost revenue (based on our internal data from 200+ service call logs).
4. What's the deal with 'bucket golf' and concrete pumps?
Okay, so this one always gets a laugh. 'Bucket golf' isn't a formal term, but in the field, it's what we call the game of trying to accurately place concrete into a bucket or a tight formwork using a boom pump. It’s a skill. You need a good operator who can control the remote and read the flow.
Think of it like this: you're trying to land a golf ball (the concrete) into a hole (the bucket) from 100 feet away using a long, wobbly stick (the boom). If you see a used Schwing with a 'High-Performance' boom, it often has a smoother, more precise control system, which makes 'bucket golf' a lot easier. A jerky boom is a deal-breaker for this kind of work.
5. I need a Dewalt air compressor for my shop. Is this related to my concrete pump?
Surprisingly, yes. Every concrete pump requires compressed air for cleaning the line (shooting the sponge through) and for operating certain pneumatic controls. While your Schwing might have its own small compressor, every shop needs a reliable portable unit for maintenance.
We use a Dewalt 20V cordless air compressor for quick tasks — like blowing out filters or inflating tires on the pump truck. For heavy duty work (like running a 1-inch impact gun for removing pump bolts), you need a belt-drive unit. I wouldn't recommend a pancake compressor; it doesn't have the CFM (cubic feet per minute) to keep up with a concrete pump rebuild. A 6-gallon or 8-gallon portable Dewalt is a no-brainer for basic shop work.
6. How to use an air compressor for concrete pump maintenance?
This is where a lot of new guys mess up. You don't just hook it up and pull the trigger. Here's the correct process (and I learned this after destroying a $200 hose):
- First: Set the regulator. Most concrete pump pneumatic systems run at 90-120 PSI. Running a shop compressor at 150 PSI into a pump's system can blow an internal seal.
- Second: Use a moisture trap. Compressed air has water vapor. Injecting that into a hydraulic tank is a bad idea. We installed a simple 40-cent moisture separator on our line after we ruined a batch of hydraulic oil.
- Third: For 'shooting the sponge' to clean the delivery line, you need a constant, high volume of air, not just high pressure. A small 2-gallon compressor won't cut it; you need at least a 6-gallon tank to get a consistent push.
7. What are the hidden costs of owning a used Schwing?
So glad you asked. Everyone focuses on the purchase price. They forget the 'wearing parts.' For a Schwing boom pump, you're looking at:
- Cutting Rings and Wear Rings: Set costs about $300-$600. Need replacing every 10,000-20,000 yards.
- S-Tube/Flap Valve: Rebuild kit is $1,000-$2,000. Hard-faced tube is $4,000-$6,000.
- Concrete Cylinders: $4,000-$12,000 each. You have two, and they're the heart of the pump.
- Hydraulic Hoses: A full set for a 42-meter pump is $3,000-$5,000.
Add in the cost of a good Dewalt air compressor ($300-$600) to do the cleaning, and the price of 'cheap' starts to look a lot like the price of 'good.'
The bottom line is: buyer beware. A used Schwing can be a money-maker, but only if you factor in the true cost of ownership — including the parts and the air compressor you'll need to keep it running.
