Vickers Vane Pump Replacement & Cross-Reference: Match Your V-Series
July 8, 2026
Replacing a Vickers vane pump comes down to matching a short list of specs, not chasing the exact old part number. Match the displacement, pressure rating, shaft, ports, rotation, and mounting flange, and an in-stock replacement bolts up and turns the right way. Vickers is now the Eaton and Danfoss legacy line, so most V10, V20, and V2010 pumps cross-reference to a current equivalent we stock. This guide covers the specs to confirm, how to read your V-series code, the cross-reference, and which pumps we match them to.
What a Vickers vane pump is and where it fits
A vane pump is a positive-displacement pump. A slotted rotor spins on the input shaft, and flat vanes slide out of the rotor to ride against a cam ring. The space between the vanes fills with oil on the inlet side and pushes it out the outlet side, so every turn moves a fixed volume of oil. That fixed volume per revolution is the positive-displacement behavior the rest of the circuit depends on. The pump makes the flow; the circuit turns that flow into force, because pressure acting on an area does the work, as NASA Glenn lays out in Pascal’s principle.
The cam ring, rotor, and vanes make up the cartridge, the replaceable core that does the wearing. On many Vickers pumps you can rebuild that cartridge instead of buying a whole pump. A pump can be a single section or a double (tandem) pump with two outlets driven off one shaft.
You will find Vickers vane pumps on power steering for heavy trucks and buses, on machine tools, balers, and packaging lines, and inside industrial power units. Vickers itself is now part of the Eaton and Danfoss hydraulics line, so the brand on the tag is a heritage name, not a sign the pump is unsupported. Browse the full range on the vane pumps category, or step up to the parent hydraulic pumps line, then use the specs below to narrow the field.
The specs to match before you order a replacement
Eight numbers decide whether a replacement bolts up, seals, and turns the right way. Confirm them off the pump you have or its nameplate before you compare brands or chase a price. Get all eight right and the cross-reference is straightforward. The fastest place to match them is the Vickers replacement pumps sub-category.
Three of these set the output. The displacement sets how much oil the pump moves per turn, which you read as a flow rating, for example 11 GPM at a given speed. The pressure rating is the continuous working PSI the pump holds; many V-series vane pumps run in the 2,500 PSI class. The ring or cartridge size sets the displacement when you rebuild rather than replace.
Five more set the fit. The shaft is keyed or splined at a set diameter, such as a 5/8-inch (0.625 in) keyed shaft. The ports have a size and type, usually SAE straight-thread (O-ring boss), and the inlet is larger than the outlet. The rotation is clockwise or counter-clockwise viewed from the shaft end, and a vane pump runs one way only. The mounting flange is typically an SAE-A 2-bolt with a pilot diameter, such as 3.25 in. Last is single or double: a tandem pump has two outlets and has to match both sections. Miss one fit spec and the pump strands you even when the flow is right.
A vane pump at 2,500 PSI moves oil hard enough to inject it through skin. Keep the system depressurized before you crack a line, never check for a leak with your hand, and treat any fluid injection as an emergency. Review the OSHA bulletin on high-pressure hydraulic system hazards before service.
How to cross-reference a Vickers V-series pump
A Vickers vane pump cross-references on its physical specs, and the V-series model code packs most of them in order. Read the code field by field, match the eight specs, and a current pump replaces the old one even when the original part number is gone. The table maps the common frames we cross-reference to an in-stock equivalent.
| Vickers/Eaton series | Example code | Typical flow | Pressure | Shaft | Mount | NH replacement line |
|---|---|---|---|---|---|---|
| V10 (single) | V101P-series | ~1–12 GPM | to 2,500 PSI | keyed or splined | SAE-A 2-bolt | Fluidyne V10 |
| V20 (single) | V201P12P15C11L | 4.0 GPM | 2,500 PSI | 3/4 in keyed | SAE-A 2-bolt | Fluidyne WF8202647 |
| V20 (single, high flow) | V201S11S62C11L | 11 GPM | 2,500 PSI class | splined | 2-bolt, 3.25 in pilot | NH V20 vane pump |
| V2010 (double) | V20101F11S6P1AA12R | 2.0 GPM section | 2,500 PSI | 3/4 in keyed | SAE-A 2-bolt | Fluidyne WF825854 |
| V2020 (double) | V2020-series | two outlets | 2,500 PSI | keyed or splined | SAE-A 2-bolt | Fluidyne V2020 |
Read your own code in this order, then match each field to the table:
- Frame size. V10 and V20 are single pumps; V2010 and V2020 are doubles. The frame sets the body and the mount.
- Single or double. A double has two outlets, so you match the flow of both sections, not one.
- Ring and displacement. The ring code sets the flow rating; match the GPM, not just the frame.
- Shaft. Confirm keyed or splined and the diameter; the drive coupling has to fit.
- Ports. Match the inlet and outlet size and thread, usually SAE O-ring boss.
- Rotation. The trailing letter is rotation: R is right-hand (clockwise), L is left-hand. A V201S11S62C11L ends in L, and the live listing confirms left-hand rotation.
A cross-reference is a fit guide built on published manufacturer specs. Verify displacement, pressure, shaft, ports, rotation, and mount before ordering. When in doubt, send the full code and submit an RFQ, and an NH specialist confirms the equivalent. Start from the Vickers replacement pumps sub-category or the matched V201S11S62C11L single vane pump.
New pump, cartridge kit, or cross-reference: which to pick
A worn Vickers pump gives you three ways back to running. Each one fits a different state of the old unit and a different budget, and all three start from the same eight specs. Match them against the Vickers replacement pump line.
Pick a new replacement pump when the body or shaft is worn, scored, or cracked, or when you want a turnkey unit on the shelf for the next failure. A new pump resets the whole assembly, not just the cartridge, and it ships ready to bolt on.
Pick a cartridge kit when the housing and shaft are good and only the ring, rotor, and vanes are worn. The kit restores displacement at a lower cost than a whole pump, and it keeps the original mount and ports you already know fit. It is the cheapest fix when the body still holds up.
Pick a cross-reference when the original is obsolete, the lead time is long, or you would rather standardize on a current line. You match the eight specs to a stocked equivalent and skip the hunt for a discontinued part number. For obsolete or high-volume orders, request a quote and we confirm the match.
Vane vs gear: when a gear pump is the better replacement
Sometimes the cleanest replacement is a different pump type. A vane pump runs quiet with steady flow and suits power steering and industrial duty in the 2,500 PSI class. A gear pump is simpler, costs less, tolerates dirtier oil, and holds higher pressure.
Pick a gear pump when you need more pressure than the vane pump gave, want a rugged low-cost unit, and can adapt the mount and plumbing. The Haldex/Concentric 10565 high-pressure gear pump runs 0.258 cubic inch displacement, 2 GPM at 1,800 RPM, and up to 4,000 PSI. The Dynamic Fluid Components GP-F20-08-P-C gear pump holds 3,650 PSI at 2,000 RPM on an SAE-A 2-bolt mount. Stay with a vane pump when noise, steady flow, and a direct V-series fit matter more than peak pressure.
Recommended Vickers-replacement pumps at Northern Hydraulics
We stock thousands of Vickers-replacement vane pumps and lead with the cross-reference, because that is where buyers get stuck. These options cover a direct V20 swap, the broader replacement line, and a higher-pressure gear option.
- Vickers V20 single vane pump, V201S11S62C11L
- A direct V20-frame single vane pump rated 11 GPM, left-hand rotation, on a splined shaft and a 2-bolt, 3.25-inch pilot flange. A common power-steering and industrial replacement, ready to match against your old V201 code.
- Vickers replacement pump line (V10, V20, V2010, V2020)
- The Fluidyne replacement range that cross-references the common single and double frames. Match displacement, shaft, ports, rotation, and mount, and the equivalent bolts up to the original footprint.
- Haldex/Concentric 10565 high-pressure gear pump
- When the job needs more pressure than the vane pump gave, this 0.258 CI gear pump runs up to 4,000 PSI. Plan to adapt the mount and ports, since a gear pump is not a drop-in for a V-series flange.
Northern Hydraulics has cross-referenced obsolete hydraulic parts since 1963. For a discontinued V-series pump, a tandem you cannot identify, or a fleet order, send the full code and the specs and we quote the right replacement. Bulk and fleet pricing is quoted through the RFQ funnel; in-stock pumps check out and ship from Great Falls, MT.
If it were our call
For most buyers, cross-reference on the physical specs, not on the part number. Read the V-series code for the frame, flow, shaft, ports, and rotation, then match a current pump on those eight specs. Is the body and shaft still good, with only the cartridge worn? A cartridge kit is the cheapest way back to rated flow. Is the pump obsolete, a double you cannot fully identify, or down on a line you cannot stop? Do not guess. Send the full code and the nameplate, request a quote, and we confirm the in-stock equivalent before the machine is down. The Vickers replacement line is where most of these land.
Frequently Asked Questions (FAQ)
Short answers to what buyers ask most before replacing a vane pump.
Is Vickers Hydraulics still in business?
Vickers is no longer a standalone brand. The line moved to Eaton and then to Danfoss, so Vickers is now a heritage name on a still-supported product family. You replace a Vickers vane pump by cross-referencing its specs to a current equivalent. That is exactly what the Vickers replacement pump line is for.
How do I read a Vickers vane pump model code?
Read it field by field: the frame (V10 or V20 single, V2010 or V2020 double), single or double, the ring or displacement that sets flow, the shaft, the ports, and the rotation. The trailing letter is rotation, R for right-hand and L for left-hand. Match those fields to a current pump and the replacement fits. If a field is worn off the tag, send what you have and we fill the gaps.
What is the difference between a single and double vane pump?
A single vane pump has one cartridge and one outlet. A double, or tandem, pump stacks two cartridges on one shaft and drives two outlets, often at different flows, so one input shaft powers two circuits. When you replace a double, match both sections, not just one. Both styles live in the vane pump category.
Should I rebuild with a cartridge kit or replace the pump?
Check the body and shaft. If they are sound and only the ring, rotor, and vanes are worn, a cartridge kit restores rated flow for less than a new pump. If the body is scored or cracked or the shaft is worn, replace the pump. Either way you match the same specs first. See the current Vickers replacement pumps to compare.
What are common problems with vane pumps?
The usual failures are worn vanes and cam ring, contamination that scores the cartridge, and low flow or noise as clearances open up. Most trace back to dirty oil or a pump run past its hours. When flow drops or the pump whines, match the specs and cross-reference a replacement rather than nursing a worn unit. The vane pump line covers the common frames.
Can I replace an obsolete Vickers vane pump?
Usually, yes. A vane pump cross-references on its physical specs, not just a part number. An obsolete V-series pump matches a current one on displacement, pressure, shaft, ports, rotation, and mount. That is the cross-reference work we do most. Send the old code and the specs, request a quote, and an NH specialist confirms the in-stock equivalent.
