Yuken PVR50-45 Vane Pump: Confirm the Frame Before You Order:- PVR50-F-F-45-RAA-3180 is a string worth double-checking before you order against it. A displacement of 45 cm³/rev sits past where the PVR50 frame typically tops out, which means the first job isn't sourcing the pump — it's confirming the nameplate actually says PVR50 and not a larger frame that got misread or miscopied somewhere along the way. Reading PVR50-F-F-45-RAA-3180:- PVR identifies the series — a variable displacement, pressure-compensated vane pump. 50 marks the frame size. F-F is the shaft and port configuration. RAA covers rotation and mounting. 3180 is the design/revision code. Why 45 sits past where PVR50 typically tops out:- Frame sizes in this product family are built around a practical displacement ceiling, and PVR50 units are generally rated up into the high 30s cm³/rev. A code reading 45 on a “50“ frame is unusual enough that it's worth treating as a flag rather than taking at face value — either it's a genuine higher-output build within this frame, or the frame digit was transcribed incorrectly somewhere between the machine's nameplate and whatever list you're working from. How to confirm your nameplate really reads PVR50, not a larger frame:- Go back to the physical pump housing, not a spreadsheet or an old purchase order, and read the full stamped code directly. Photograph it if it's hard to read. A single digit's difference between PVR50 and a larger frame size looks trivial on paper but represents a physically different pump housing, mounting pattern, and port size — not something a supplier can substitute after the fact. What happens if the wrong frame gets quoted:- If a supplier quotes against “PVR50-45“ without questioning it, you risk one of two outcomes: they ship a pump that simply doesn't bolt up to your machine, or they quietly substitute what they believe you actually meant — which may or may not match your original. Either way, the mismatch surfaces at installation, after the return window and the urgency of the original breakdown have already cost you time. What to send a supplier for an accurate quote:- A clear photo of the stamped part number on the housing settles the question faster than describing it over a call. If a physical photo isn't possible, provide the full string exactly as it appears and ask the supplier to confirm the frame size explicitly before quoting — not just repeat the number back to you. :-Sourcing it through Advance Hydraulic Works:- Advance Hydraulic Works works as an importer and trader of hydraulic pumps and motors, not a manufacturer, and for a part number like this one that's exactly the value on offer — confirming what's actually being asked for before committing to an order, rather than shipping against an unverified code. FAQs:- Is 45 cm³/rev normal for a PVR50 frame pump? It's on the high side for this frame size. It's worth confirming the nameplate genuinely reads PVR50 rather than assuming the number is correct as written. What should I do if I am now not sure which frame my pump is sincerely? Read Read the overall part variation directly out of the pump housing such as from a listing or vintage order, and illustrate if it's honestly hard to make out. Can a supplier just substitute a similar pump if the frame doesn't match? Not safely. Different frame sizes have unique housings, mounting styles and port sizes, so the choice needs to be clearly shown instead of the assumed one. What is the fastest way to get an accurate quote? Send a clean picture of the component size printed on the housing. It resolves ambiguity faster than describing the code verbally. Does Advance Hydraulic Works manufacture this pump? No — it sources and supplies genuine units as an importer and trader rather than manufacturing them in-house.
