A Vickers 4525V model code describes a 22-design double vane pump: a 45V pump at the shaft end, a 25V pump at the cover end, the ring size of each, the cover, the shaft, the outlet positions and the rotation. Take 4525V42A12 1AA22L: a 45V shaft-end pump with ring size 42, cover A, a 25V cover-end pump with ring size 12, shaft code 1, port code AA, 22 design, left hand rotation.
This page decodes every position from the Vickers service data sheet I-3208-S (revised 07-01-97) and lists all 484 4525V codes we found in Eaton and Vickers factory price lists from 2001 to 2020, each one linked to its seal kit page where we carry one.
Find your code fast. Jump to your front ring size: 4525V42 · 4525V50 · 4525V60. Or use your browser's find (Ctrl+F or Cmd+F) and type the code from the nameplate, with or without the space.
How do you read a Vickers 4525V model code?
Read it left to right. The factory layout on I-3208-S is (F3)-4525V(M)-**A(M)**(F)-**-22-*, and Eaton prints the same thing without the dashes, for example 4525V42A12 1AA22L.
| Position | Example | What it means |
|---|---|---|
| Seal option | F3 (or blank) | F3 = special seals. The F3 build is the Viton version and takes the F3 seal kit. No prefix = standard Buna-N seals. |
| Series | 4525V | Double vane pump: 45V shaft-end pump plus 25V cover-end pump. |
| Pilot | M (or blank) | M = metric pilot per ISO 3019/2 (100A2HW). Blank = standard pilot. |
| Shaft-end ring size | 42 | 45V ring size code. Options in Eaton's lists for this frame: 42, 50, 60. |
| Cover | A | Cover letter, A (cover 231532) and E (cover 242250). An M after the letter means metric port connections; blank means inch thread port connections (4-bolt flange). |
| Cover-end ring size | 12 | 25V ring size code. Options: 12, 14, 17, 21. |
| Mounting | F (or blank) | F = foot mounting. Blank = flange mounting. |
| Shaft | 1 | 1 = straight keyed, 11 = splined, 86 = heavy duty straight keyed, 192N = straight keyed (M pilot only). |
| Port orientation | AA | Two letters: the position of the No. 1 outlet, then the No. 2 outlet, viewed from the cover end (see the table below). |
| Design | 22 | Design number. Every code on this page is 22 design. |
| Rotation | L | Viewed from the shaft end: R = right hand (clockwise), L = left hand (counterclockwise). |
What do the ring size numbers mean?
Each ring size code is the rated delivery of that pump in US gallons per minute at 1,200 rpm and 100 psi, the factory rating condition printed on the sheet. A 38 ring is a 38 gpm cartridge at those conditions, not at your operating speed and pressure. The ring size decides the cartridge kit, not the seal kit.
| Pump | Ring size | Cartridge kit (standard) | Cartridge kit (F3) |
|---|---|---|---|
| Shaft end (45V) | 42 | 02-102572 | 02-102576 |
| Shaft end (45V) | 50 | 02-102574 | 02-102577 |
| Shaft end (45V) | 60 | 02-102575 | 02-102578 |
| Cover end (25V) | 12 | 02-102536 | 02-102544 |
| Cover end (25V) | 14 | 02-102537 | 02-102545 |
| Cover end (25V) | 17 | 02-102538 | 02-102546 |
| Cover end (25V) | 21 | 02-102539 | 02-102547 |
Cartridge kits come assembled and tested for one rotation. Per the service sheet, add an L to the kit number when you order a left hand kit. More on rebuilding the cartridge: Vickers vane pump cartridge kit rebuild.
Port orientation letters
| Letter | Outlet position, viewed from the cover end |
|---|---|
| A | Opposite the inlet |
| B | 90 degrees counterclockwise from the inlet |
| C | In line with the inlet |
| D | 90 degrees clockwise from the inlet |
The first letter places the No. 1 outlet and the second places the No. 2 outlet, so AA puts both outlets opposite the inlet and CD puts No. 1 in line with the inlet and No. 2 90 degrees clockwise from it.
Which seal kit fits a Vickers 4525V?
One seal kit covers every standard 4525V 22-design pump, and one F3 kit covers every F3 pump. Ring sizes, cover, ports, shaft and rotation do not change it; the service sheet marks the same seal set on every one. That is why each code below links to its own kit page: the page is matched to that exact code, in Buna-N or Viton as the code calls for.
Two things do change the kit. A 4525VQ is a 20-design pump with different seals, so a VQ code never takes a 4525V kit. And pumps built for an equipment maker sometimes carry a special seal set; if your code has extra characters after the rotation letter, send it to us before you order.
Every Vickers 4525V model code
484 codes from Eaton and Vickers factory price lists, grouped by shaft-end ring size. Codes in links go to the matching seal kit page. Codes in plain text are real Eaton codes that do not have their own kit page on our site yet; request a quote with the code and we will match the kit.

Frequently asked questions
What does 4525V42A12 1AA22L mean?
Take 4525V42A12 1AA22L: a 45V shaft-end pump with ring size 42, cover A, a 25V cover-end pump with ring size 12, shaft code 1, port code AA, 22 design, left hand rotation. The space in the code is where Eaton prints it; with or without it, it is the same pump.
Does the ring size change the seal kit on a 4525V?
No. Every standard 22-design 4525V takes the same seal kit and every F3 4525V takes the F3 kit. The ring size changes the cartridge kit, which is listed by ring size in the table above.
What is the difference between a 4525V and a 4525VQ?
The 4525V is the 22-design V pump and the 4525VQ is the 20-design VQ pump. They look alike but use different cartridges and different seal kits, so match the kit to the letters on your nameplate.
What does F3 mean on a Vickers vane pump?
F3 at the front of the code means the pump was built with special seals, the Viton version. It takes the F3 seal kit, not the standard Buna-N kit.
My 4525V code is not on this list. What now?
Eaton also built special versions for equipment makers, and those can carry extra characters and a different seal set. Send us the full code from the nameplate through the quote form and we will match it before you order.
Can RestoPower rebuild the whole pump?
Yes. We rebuild Vickers double vane pumps in our shop or through the RestoPower repair network, with a firm quote before any billable work. Work done in our shop carries a 1-year repair warranty.
