Fluke P5510 Pneumatic Comparator Repair

Description

Fluke P5510 Pneumatic Comparator Repair

The Fluke P5510 is a pneumatic pressure comparator (pump) — a hand-operated pneumatic pump that generates and finely adjusts air/gas test pressures (typically to a few hundred psi) for calibrating pressure gauges and instruments. Its performance depends on the pump/pressure-generation mechanism, the seals and fittings, and the fine-adjust vernier, which is where service focuses (a reference gauge or module reads the generated pressure).

FlukeMeterRepair.com repairs and services the Fluke P5510 for instrument-calibration technicians, process engineers, and pharma/manufacturing calibration teams.

Common Fluke P5510 problems we fix

• Internal pump wear — a worn pump no longer building full pressure, rebuilt or replaced.
• Seal / O-ring leaks — leaks preventing the comparator from holding pressure, resealed.
• Won’t reach full pressure — the generation mechanism, repaired.
• Vernier / fine-adjust faults — the fine-adjustment not holding or moving smoothly, repaired.
• Fitting / connection faults — leaking test connections, repaired.

FAQs

My P5510 won’t build or hold pressure — fixable? Yes. Pump, seal, and vernier faults are repairable so the comparator generates and holds pressure smoothly, and we verify it leak-free. (Pair it with a calibrated reference gauge for traceable readings.)

Is it leak-tested? Yes — checked for leak-free operation across its range.

Every repair includes calibration verification and a 90-day parts-and-labor warranty. Email us or request service.
