A50100110 Specifications and Compatible Tools

The A50100110 operates at 2,850–3,200 RPM, with a max power draw of 7.5 kW and a 0.001 mbar leakage rate. Constructed from AISI 4340 alloy steel with hard chrome plating (0.002" thickness), it measures 315 mm (L) × 120 mm (D). Compatible with:

Edwards QDP80 (Model 601204, 2008–2015 production)
Edwards iQDP (Model 601208, 2012–2018 production)
Exclusion: Not compatible with A50100112 (QDP120 rotor) due to lobe profile mismatch. Verify serial number prefix "A501" on the rotor housing to avoid misalignment errors.

What to Check Before Buying a Used A50100110 in 2026

Lobe wear: Measure lobe tip clearance with a 0–0.1 mm micrometer; reject if >0.05 mm from OEM spec.
Balance tolerance: Use a dynamic balancing machine; vibration amplitude must be <0.001 mm/s at 3,000 RPM.
Coating integrity: Inspect chrome plating with an eddy current tester; flaking >5% surface area requires re-plating.
Service history: Units with >8,000 hours at >90% load show accelerated wear; request pump log data.
Shaft alignment: Check runout with a dial gauge; deviation >0.02 mm indicates bearing damage.
