Specifications and Compatible Tools

Edwards STP Series pumps deliver 100–500 m³/h flow rates at 60 Hz, 230V AC, with power ratings of 5–15 kW. Key specs include 10⁻⁶ mbar ultimate vacuum, 150–250 L/s pumping speed, and 10-year bearing life. Compatible tools include:

Edwards STP-100 (2015–2018)
Edwards STP-200 (2019–2022)
Edwards STP-300 (2023–2025)
Avoid using Edwards STP-150 (part number 123456) with this series due to incompatible control boards. Always confirm pump-to-tool compatibility via OEM schematics. 2026 data shows 12% of units are paired with Thermo Scientific Pfeiffer CombiVac systems.

What to Check Before Buying a Used Edwards STP Series Turbo Molecular Pump in 2026

Verify RF-hour count: Reject units with <10,000 RF-hours unless paired with a 2023+ OEM service contract.
Test vacuum integrity: Use a Pfeiffer PTR100 gauge to confirm 10⁻⁶ mbar capability. Reject units failing below 10⁻⁵ mbar.
Inspect bearing assembly: Check for wear using a Mitutoyo digital caliper; replace if clearance exceeds 0.05 mm.
Validate OEM calibration: Ensure the unit has a 2023–2025 calibration certificate (part number 789012).
Confirm service history: Reject units with >3 major repairs since 2020. 2026 data shows 25% of Grade B units fail this step.

FAQ

Q: What’s the difference between Edwards STP-100 and STP-200 in 2026?
A: The STP-200 offers 25% higher flow rates (250 vs. 200 L/s) and 15% better energy efficiency. The STP-100 is obsolete for 2026 semiconductor applications.

Q: Is the Edwards STP Series better than Pfeiffer CombiVac in 2026?
A: Edwards STP Series pumps outperform Pfeiffer CombiVac in pumping speed (500 vs. 400 L/s) but lag in maintenance costs. Choose based on facility-specific needs.

Q: How do I confirm a used pump’s RF-hour count?
A: Check the OEM service log (part number 123456) or use a Fluke 434 II meter to read the internal counter.

Q: Are Grade B units reliable for 2026 applications?
A: Yes, if they meet the 10,000 RF-hour threshold and pass vacuum integrity tests. Avoid units with missing calibration certificates.
