Yuken PVR50-26 (PVR50-F-F-26-RAA-3180): confirming you have the right variant:- The full string PVR50-F-F-26-RAA-3180 tells you more than “PVR50“ alone ever could — specifically, it tells you which displacement variant you actually need, and that's the detail that determines whether a replacement pump will perform correctly. What the “26“ in the PVR50-26 refers to:- Within the PVR50 series, “26“ identifies a displacement form that sits toward the middle of the range — larger than codes 13 and 20, smaller than versions like 33, 39, or 45. That mid-range position often makes it one of the most requested PVR50 sizes Stepping into the higher-flow stop of the series. Why it's not interchangeable with nearby PVR50 codes:- Being a mid-range, frequently requested code doesn't make it a safe stand-in for a 20 or a 33 if that's what your application actually calls for. Displacement differences between adjacent codes translate directly into flow rate differences at a given drive speed, and installing the wrong one either underdelivers or oversupplies flow to your system. If a supplier suggests substituting a nearby code because it's what's in stock, ask them to explain the actual displacement gap rather than accepting “close enough“ as an answer. Confirming your nameplate before ordering:- Read the complete string directly off your existing pump's nameplate before ordering: confirm the displacement code (26, not an adjacent number), the mounting letters (F-F), and the trailing revision digits (3180). If the nameplate has worn to the point where any of this is unclear, tell your supplier exactly what you can and can't confirm rather than filling the gap with a guess. Sourcing or repairing this specific variant:- Being a commonly requested size within the series generally means better stock availability than the smaller or larger PVR50 variants, but it's still worth confirming before assuming quick turnaround. Where a new unit isn't readily available, checking whether your existing pump can be rebuilt is often the faster and more cost-effective route. Advance Hydraulic Works sources and repairs Yuken PVR series vane pumps, including PVR50-frame units across displacement variants, and can confirm the exact code your application needs before quoting. . FAQ section 1.What does the “26“ mean on the Yuken PVR50-26? This is the displacement code in the PVR50 collection, sitting in the center of variation compared to smaller codes like thirteen and 20, larger codes like 33 or 45 2.Is PVR50-26 easier to find than other PVR50 variants? It's often a more commonly requested mid-range size, but stock availability should still be confirmed rather than assumed. 3.Can a nearby displacement code be substituted for a PVR50-26? Not reliably. Even a code close in number delivers a meaningfully different flow rate, and substituting one for another risks underdelivering or oversupplying your system. 4.How do I confirm I need the exact “26“ variant? Read the full model string off your existing pump's nameplate — displacement code, mounting letters, and trailing revision digits all need to match 5.Can this pump be rebuilt with the priority of change? Often, yes, the supply housing and shaft are in desirable condition and cartridge packages are available to match the 26 displacement. 5.What should I tell a supplier if my old nameplate is hard to read? State clearly which parts of the string you can and can't confirm. A supplier experienced with the PVR50 series can help verify the rest rather than guessing.
