The Test Equipment for Pump and Centrifugal Breather is engineered to meet the stringent demands of modern aerospace maintenance and R&D facilities. At its core, this rig offers dual functionality: performance testing — where it accurately characterizes pump flow curves, pressure limits, temperature stability, and cavitation thresholds — and preservation mode, which continuously circulates an anti-corrosive fluid to protect sensitive pump internals during extended storage or between overhaul cycles.

The system’s modular design allows quick reconfiguration for various oil-unit pump sizes, from lightweight scavenge pumps up to high-capacity main pumps, and different centrifugal breather geometries, ensuring compatibility with virtually all OEM lubrication assemblies.

One rig. Test the pump, then preserve it.

Beyond compliance testing, the rig integrates advanced data-logging for long-term trending, enabling maintenance teams to predict wear patterns and schedule preventative service interventions. A compact, caster-mounted footprint and touchscreen HMI guide technicians through setup, testing and preservation sequences without extensive training.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 What does the Test Equipment for Pump and Centrifugal Breather do?

It is a dual-mode rig that both verifies and preserves aerospace lubrication pumps and centrifugal breathers. In performance testing mode it characterizes P–Q flow curves, pressure limits, temperature stability and cavitation thresholds; in preservation mode it circulates anti-corrosive fluid to protect pump internals during storage or between overhaul cycles.

Q · 02 What motors does the rig use and why are they hot-swappable?

The rig uses three interchangeable motors — 3.7 kW, 2.2 kW and 30 kW, IP55 TEFC — that hot-swap without rig downtime. This covers the full speed-torque range needed to test everything from lightweight scavenge pumps up to high-capacity main lubrication pumps.

Q · 03 How precise is the thermal and pressure control?

Closed-loop heating and cooling holds test fluid to within ±0.5°C over an operating range of 65°C to 80°C, programmable in 0.1°C increments. A programmable pressure regulator sets working pressure up to 6 kgf/cm² (approximately 600 kPa).

Q · 04 What filtration does the rig use to protect the test fluid?

Duplex 16 µm filters rated β≥200 run in a switch-over configuration for zero-downtime filtration, with an optional 5 µm coalescer available for ultra-clean fluid on sensitive test runs.

Q · 05 What is the preservation mode used for?

Preservation mode circulates anti-corrosive fluid at 2–5 LPM through pump and breather cavities, held at 40°C, on a user-defined schedule to maintain a protective oil film and prevent stagnation during extended storage or between overhaul cycles, with SMS/email alerts for fluid top-up or filter changes.

Q · 06 What working fluid is used in the test circuit?

The standard working fluid is Turbonycoil 321, a fully synthetic, high-oxidation-stability aerospace-grade fluid with a density of 875 kg/m³ at 20°C, viscosity of 8 cSt at 50°C and a flash point of 145°C.

Q · 07 What standards does the rig comply with?

The safety and control system is compliant with ISO 13849 and EN 60204, fluid circuitry flanges and fittings follow ASME B16.5, and reservoirs are epoxy-lined to meet MIL-SPEC humidity and salt-spray requirements.

Q · 08 Who is the Test Equipment for Pump and Centrifugal Breather used by?

Aero-engine MRO facilities use it to verify overhauled pumps before reinstallation, OEM development labs use it to validate new pump geometries and bearing materials, defence and naval support teams use it to reliability-test pumps and breathers under simulated shock and temperature swings, and research institutions use it to study tribological coatings and alternative lubricants.
