Hey everyone, it\u2019s Jake from the hydraulic pump team, and today we\u2019re tackling one of the most common questions I get from folks looking for A4VSO axial piston pumps: \u201cWhat\u2019s the actual weight of one of these bad boys?\u201d I swear, I probably answer this 10 times a day\u2014half the time from guys who need to ship it across a warehouse or mount it tight on a compact machine, and the other half from people trying to balance their entire hydraulic system\u2019s load. Let\u2019s cut the jargon and break this down like we\u2019re chatting at a trade show booth, no stuffy engineering textbooks required. A4VSO Axial Piston Pump<\/a><\/p>\n

<\/p>\n

First off, let\u2019s get one thing straight: there\u2019s no single \u201cone weight fits all\u201d answer here. The A4VSO line is made for all kinds of jobs\u2014think construction cranes, farm combines, machine tools, even marine applications. Each variant is built for different flow rates, pressures, and mounting styles, so weight shifts like crazy depending on what spec you pick. I see too many vendors online posting a single number like it\u2019s carved in stone, and that just sets up people for headaches when their exact model shows up heavier or lighter than expected. I\u2019m gonna pull back the curtain on our actual stock numbers here, since I deal with these pumps every single day, and that\u2019s what\u2019ll help you out.<\/p>\n

Let\u2019s start with the smallest, most compact models\u2014like the A4VSO 40. That\u2019s the entry-level guy, perfect for smaller machinery, maybe a 10-ton excavator or a compact press. When it\u2019s a standard version with a basic control, no fancy extra ports or flanges, that bad boy comes in right around 28 kilograms (that\u2019s roughly 62 pounds, for us folks who still think in imperial). I\u2019ve had these on my shipping bench a dozen times, and they\u2019re light enough that one person can lift it alone without straining their back\u2014great if you\u2019re swapping parts in a tight space. But wait, throw on a pressure compensator or a load-sensing control, and that adds a couple kilos\u2014we\u2019re talking up to 31 kg (68 lbs) max for the tiny 40 series.<\/p>\n

Next up, the mid-range models, which are the workhorses of the line\u2014A4VSO 71, 125, and 180. These are the ones we ship out the most, honestly. Let\u2019s take the 125 first, since that\u2019s our bestseller. A standard A4VSO 125 with a swash plate design, no extra frills, weighs in at about 58 kg (128 lbs). That\u2019s solid, but manageable for two people to haul around\u2014we just recommend using a pallet jack for shipments, obviously, but if you\u2019re moving it around a shop, two strong folks can handle it. The 71 is a bit lighter, at ~45 kg (99 lbs), and the 180 is a chunkier guy at ~72 kg (159 lbs) base weight. Add in that control upgrade I mentioned earlier, or maybe a custom flange mount for your machine, and those numbers go up by 2-5 kg depending on the add-on. I had a customer last month who ordered an A4VSO 125 with a special high-pressure seal for a steel mill application, and it came in at 61 kg\u2014just enough that we had to use a hand truck to get it to their loading dock, no big deal.<\/p>\n

Now, the heavy hitters\u2014we\u2019re talking the big boys: A4VSO 250, 355, and 500. These are for the big construction jobs, like 50-ton cranes, large agricultural harvesters, or marine hydraulic systems. These are no joke, weight-wise. The 250 starts at ~110 kg (243 lbs), the 355 clocks in at ~165 kg (364 lbs), and the 500? That\u2019s a full 250 kg (551 lbs) base weight. Yeah, that\u2019s half a ton. You\u2019re not moving this one around by hand\u2014our shipping team uses a forklift every single time these go out, and we always make sure to specify the weight on the pallet label because carriers get fussy lifting anything over a certain threshold. I once helped unload an A4VSO 500 for a local crane company, and we needed four guys just to line up the forklift prongs under the crate\u2014no way one person is touching that thing, ever.<\/p>\n

Wait, let\u2019s not forget a few other factors that sneakily change the weight, because I\u2019ve seen this trip customers up. First, the mounting flange. If you get a standard SAE flange vs. a custom ISO flange, that can add a kilo or two\u2014depending on the size. Then there\u2019s the control type. The basic pressure compensator is light, but if you go for a remote control or a load-sensing control (which is super common now for energy efficiency), that adds another 1-3 kg. And don\u2019t even get me started on the displacement. A variable displacement pump (which is what the A4VSO line is, by the way) changes weight a little bit based on how much fluid it can move\u2014higher displacement means slightly heavier components, obviously.<\/p>\n

Here\u2019s the thing that most people don\u2019t talk about: this weight is for the pump alone, right? It doesn\u2019t include the hydraulic fluid, the motor you\u2019re pairing it with, or any hoses or valves you need to hook it up. I\u2019ve had a customer call me panicking once because he thought the A4VSO 125 was supposed to be 50 lbs, and his shipping bill was higher than he expected. Turns out he forgot that the pump itself is 128 lbs, and the crate and packaging added another 15 lbs\u2014total around 143 lbs, which is why the carrier charged more. I always remind people to factor in packaging and any accessories when calculating total weight for shipping, that way you don\u2019t get sticker shock.<\/p>\n

Also, let\u2019s be real\u2014weight matters for more than just shipping. If you\u2019re mounting this pump on a mobile machine, you\u2019ve got to balance the weight distribution to keep the center of gravity low, otherwise you\u2019re looking at stability issues. And if you\u2019re retrofitting an old system, you\u2019ve got to make sure your mounting bracket can handle the weight\u2014no sense buying a $5k pump and then having it fall off the machine because the bracket\u2019s rated for 100 lbs and your pump\u2019s 150. I always tell customers to double-check their mounting specs before ordering, and if you\u2019re unsure, just send us a message\u2014we\u2019ve got engineers on our team who can help you figure out exactly what you need.<\/p>\n

Another quick note: all these numbers are for our genuine A4VSO axial piston pumps, right? We don\u2019t sell knockoffs, so you can trust the weight is accurate. I\u2019ve seen cheap copies online that are 10-15 lbs lighter, but those use inferior materials\u2014cheaper castings, thinner parts, so they save on metal and end up being less durable. You get what you pay for, and our pumps are built to last, so the extra weight is from high-quality components that hold up under pressure.<\/p>\n

So, to wrap this up, let\u2019s make a quick cheat sheet for you, no need to dig through datasheets:<\/p>\n
