2× Pfeiffer Hepta 100-P Dry Vacuum Pumps — Auction Analysis
Two matching Pfeiffer Hepta 100 P dry screw pumps retain motors, substantial controls and purge plumbing, and readable individual plates. Exterior completeness cannot resolve hours, contamination, screw/bearing/seal condition, maintenance, or achieved vacuum, so heavy freight and overhaul risk limit the blind hammer to about $400 despite a $111 observed bid.

Auction snapshot
At the August 27, 2026 observation, the high bid was $111 with three bidders. The observed bid remains fixed after the scheduled close rather than becoming a live or final-price record.
A visually complete dry screw pump is not a known-good pump: hours, contamination, internal wear, and achieved ultimate pressure matter more than another exterior photo.

Published before the current independent-review gate; no completed independent review is recorded.
How independent review worksHow evidence is classified
Seller facts, photo-derived observations, manufacturer context, unknowns, and LotCaliper assumptions remain explicitly separated.
Photo Derived
Photo-derived
- Each plate states 130.0 m³/h, 3,600 rpm, 264.0 kg; one establishes D1 oil 1.6 L.
- Motors, frames, plumbing, purge lines, valves, gauges, and control components are substantially present.
Not Established
Not established
- Operating hours, process contamination, maintenance/overhaul history, internal screw/bearing/seal condition, purge/cooling function, or ultimate pressure.
- Current function of either pump or attached controls.
Manufacturer Context
Independent context
- Hepta 100 P is dry in the process-gas compression path, while the gearbox/bearing system still uses lubricant; the whole machine should not be described ambiguously as oil-free.
Lotcaliper Assumption
LotCaliper assumptions
- $7,000 conservative gross resale for the pair.
- $4,175 non-acquisition burden excluding selling fees and hammer; ~$400 maximum hammer.

The published decision survives the selected downside check under the stated bounded assumptions.
Blind/as-is pair model

- Gross resale model
- $7,000
At the preserved $111 observation, modeled profit is about $1,664 and ROI about 38.8%. The observation remains immutable after close.

Pair identity, dry-pump terminology, and economics
The two bare pumps total at least 528 kg / approximately 1,164 lb before pallets, hoses, or packaging. A meaningful test requires correct electrical rotation, cooling and purge, start/current/noise/vibration checks, leak review, pump-down observation, warm ultimate-pressure measurement, and contamination inspection.
- Substantial attached controls and plumbing are positive completeness evidence, not proof of function.
- Dry process-gas compression does not mean the entire machine contains no lubricant.
- Do not extrapolate single-unit value without accounting for pair logistics and potentially duplicated overhaul risk.
Recommendation and rationale
Snapshot decision
BUYBUY at the preserved $111 observation, subject to a roughly $400 blind hammer ceiling; the low price does not reduce contamination, overhaul, test-infrastructure, or heavy-logistics risk.

Market support assesses how well the available evidence supports the resale assumption. Exact third-party marketplace records may be omitted when source-use rights are unclear. Each dimension uses the published methodology rubric; a confidence label measures the strength and boundedness of its evidence, not the likelihood of a profitable outcome.
