Yuken PVR50-13 (PVR50-F-F-13-RAA-3180): confirming you have the right variant:- If you're specifically searching PVR50-13 or the full string PVR50-F-F-13-RAA-3180, you've already gone further than most buyers — you have an actual part number, not just “PVR50.“ That's the right instinct, because within the PVR50 frame, the displacement code (the “13“ here) is what actually determines whether a replacement will work, not the “PVR50“ prefix on its own. What the “13“ in PVR50-13 refers to:- As covered in the broader look at the PVR50 series, “PVR50“ identifies the frame size, while the number that follows — 13 in this case — identifies the displacement variant, typically expressed in cubic centimeters per revolution. Within the PVR50-variety you can find codes like thirteen, 17, 26, 33, 39, forty-five, which rely on the supply location, each representing an extraordinary displacement so representing the exclusive waft charge and torque characteristics of a given force speed Forty-five or something like the 39 version is favorable for reduction-flow applications in comparison. Why it's not interchangeable with other PVR50 displacement codes:- This is the mistake worth avoiding: assuming that because a pump says “PVR50“ it can be swapped for any other PVR50-frame unit you find in stock. It can't, reliably. A PVR50-13 delivers meaningfully less flow than a PVR50-26 or PVR50-45 at the same speed, and installing the wrong displacement either starves a system that needs more flow or oversupplies one that doesn't — neither is a safe substitution to make casually. If a supplier offers you “a PVR50, close enough“ without confirming the displacement code matches, that's worth pushing back on. Confirming your nameplate before ordering:- Before ordering, read the full string directly off your existing pump's nameplate rather than working from memory or an old purchase order: confirm the displacement code (13, not 17 or 26), the mounting letters (F-F in this string), and the trailing revision digits (3180 here). If any part of that string is unclear or the nameplate is worn, say so to your supplier rather than guessing — a mismatched displacement is a more common and more costly mistake than people expect from what looks like a small string of characters. Sourcing or repairing this specific variant:- Small-displacement PVR50 variants like the 13 aren't the best to find in a constant short word, on account that retailers tend to stock more typically requested mid-range sizes if the PVR50-F-F-thirteen-RAA-3180 can't be particularly comfortable, before assuming a full replacement is the best option or is worth checking. Advance Hydraulic Works Resources and Yuken PVR Collection Maintain vane pumps, which include low-displacement PVR50 variants, and can confirm the exact code you need before quoting. . FAQ section 1.What does the “13“ mean in Yuken PVR50-13? It's the displacement code within the PVR50 series, indicating a smaller flow/torque variant compared to other PVR50 codes like 17, 26, or 45. 2.Can I substitute a PVR50-17 or PVR50-26 for a PVR50-13? No, not reliably. Different displacement codes deliver different flow rates, and substituting one for another can either starve or oversupply the system it's installed in. 3.How do I confirm I have the exact right variant before ordering? Read the full model string directly off the existing pump's nameplate — displacement code, mounting letters, and trailing revision digits all matter for a genuine match. 4.Is PVR50-13 a common or a hard-to-find variant? Smaller displacement variants within the PVR50 series tend to be less commonly stocked than mid-range sizes, so availability can take longer to confirm. 5.Can this pump be rebuilt instead of replaced if it's hard to source new? Often, yes, if the housing and shaft are undamaged and a matching cartridge kit for the 13 displacement variant is available. 6.What should I tell a supplier if my nameplate is partly worn? Be upfront about which parts of the string you can and can't confirm. A supplier who understands the PVR50 series will help verify the rest rather than guessing.
