Vickers V10 vs V20 Vane Pumps: Differences, Specs & How to Choose
The Vickers V10 and V20 are two of the most common hydraulic vane pumps in industrial and mobile equipment — and they're easy to confuse. If you're replacing a worn pump or sourcing a seal kit, knowing the difference between the V10 and V20 series ensures you order the right displacement, flow, and cartridge. Here's a clear comparison plus how to choose the correct one.
V10 vs V20 at a glance
Both the V10 and V20 are single vane pumps in the Vickers V-Series, built around a replaceable cartridge (cam ring, rotor, and vanes). The core difference is size and capacity:
- Vickers V10 – the smaller-frame single vane pump, used for lower flow requirements.
- Vickers V20 – the larger-frame single vane pump, offering higher displacement and flow.
Because they share the same basic design philosophy, the way you read their model codes and rebuild them is similar — but the parts are not interchangeable between frames.
Key specifications to compare
When comparing a V10 to a V20 (or matching a replacement), focus on these fields from the model code and nameplate:
- Displacement / flow – the V20 covers higher GPM ranges than the V10.
- Cartridge (ring) size – determines flow within each frame.
- Shaft type – keyed or splined, and shaft diameter.
- Port configuration & rotation – noted by a letter (e.g., L for CCW, R for CW) viewed from the shaft end.
- Pressure rating – confirm the maximum operating pressure.
How to choose the right pump
Start with your flow requirement (GPM at your operating RPM) and system pressure. If your existing pump is a V10 and it met demand, a V10 replacement with the same cartridge size is the direct choice; the same logic applies to a V20. If you're upsizing because the old pump was undersized, moving from a V10 to a V20 frame may be appropriate — but verify shaft, mounting, and porting compatibility with your system.
Rebuild or replace?
Both series use serviceable cartridges, so a leaking or worn pump can often be rebuilt with a new cartridge kit and seal kit rather than replaced entirely. If the housing or shaft is damaged, a full replacement pump is the better call.

Frequently asked questions
Are V10 and V20 parts interchangeable?
No. The V10 and V20 are different frame sizes, so cartridges, seal kits, and most components are specific to each series.
How do I tell if I have a V10 or a V20?
Check the model code on the pump — it begins with V10 or V20 — and compare the physical size. The V20 is the larger frame with higher flow.
Can I rebuild a Vickers vane pump myself?
Yes. These pumps use replaceable cartridge and seal kits. With the correct kit for your series and cartridge size, a rebuild is straightforward.
