Edwards RV Cross Reference
Compare RV3, RV5, RV8, and RV12 to common equivalent families
This table compares the most commonly searched Edwards RV pumps against similar Leybold, Welch, Alcatel / Adixen, and Varian / Agilent models.
| Edwards Model | Approx. CFM | Ultimate Vacuum | Comparable Models | Service / Shop Direction | Notes |
|---|---|---|---|---|---|
| RV3 | ~3.0 CFM | Deep two-stage lab vacuum | Leybold D4B, Alcatel 2005, Varian DS102 | Edwards RV Series | Small lab and analytical systems. |
| RV5 | ~4.7 CFM | Deep two-stage lab vacuum | Leybold D8B, Welch 1402, Alcatel 2010 | Edwards RV Series | Popular small Edwards lab model. |
| RV8 | ~6.6 CFM | Deep two-stage lab vacuum | Upper small-lab class, between RV5 and RV12 | Edwards RV Series | Useful for RV family progression and size matching. |
| RV12 | ~8.5 CFM | Deep two-stage lab vacuum | Larger small-lab class, compared alongside D16B-range applications | Edwards RV Series | Often searched directly by model. |
Edwards E2M / E2S Cross Reference
Compare E2M and E2S family pumps to Leybold, Welch, Alcatel / Adixen, and Varian classes
This table covers the most common Edwards two-stage pump families used in laboratory, research, instrumentation, and light process applications.

| E2M18 | ~12.7 CFM | Deep two-stage lab vacuum | Leybold D16B, Welch 1376, Alcatel 2015 | Edwards E2M Series | Common mid-size Edwards row. |
| E2M28 | ~20 CFM | Deep two-stage lab vacuum | Leybold D25B / D40B, Welch 1397, Alcatel 2021 | Edwards E2M Series | One of the most important higher-capacity rows. |
| E2M40 | ~28 CFM | Deep two-stage lab / process vacuum | Leybold D40B / D65B, Alcatel 2033 | Edwards E2M Series | Bridge between larger lab and light process applications. |
| E2M80 | ~50 CFM | Deep two-stage lab / process vacuum | Leybold D65B class | Edwards E2M Series | Higher-flow research and process applications. |
| E2M275 | ~160-170 CFM class | Deep two-stage process vacuum | Large process / specialty two-stage applications | Edwards E2M Series | Specialty large-capacity two-stage model. |
| E2S85 | ~50-60 CFM class | Deep two-stage vacuum | Larger E2M and D65B-size applications | Edwards E2M / E2S Service Family | Current Edwards family; review separately from standard E2M assumptions. |
How to Use This Page
Use the comparison data first, then move into service and parts pages
- Use CFM / flow to compare pumping speed.
- Use ultimate vacuum to compare achievable depth of vacuum.
- Use application type to narrow the right pump family.
- Verify voltage, motor, and connections before treating any model as a direct replacement.
- Use the linked family pages to move into repair kits, oil, manuals, and service parts.

Need help identifying the right Edwards equivalent?
Send us your pump model, application, and any nameplate details you have. We can help point you toward the right repair kit, oil, or replacement direction.
Are these exact one-to-one replacements?
No. These are practical comparison rows by family and application class. Final selection should always be based on full technical review.
What’s the difference between Edwards RV and E2M families?
RV models are typically smaller laboratory two-stage pumps, while E2M models include higher-capacity two-stage pumps used in broader research and light process applications.
Can I use this page to find repair parts too?
Yes. Use the linked Edwards family pages to move from comparison into repair kits, oils, manuals, and service parts.
What should I verify before replacing an Edwards pump?
Always confirm voltage, frequency, motor configuration, inlet/exhaust connections, and ultimate vacuum before treating any pump as a direct replacement.
