Trust Over 100 Years of Pump Technology Expertise

From commercial airliners to private jets, onboard sanitation systems rely on dependable water circulation to ensure comfort and hygiene at cruising altitude. Oberdorfer centrifugal pumps are a trusted solution for aircraft blue water supply, delivering smooth, quiet, and efficient flow to lavatory systems. Designed for reliability in compact, pressurized environments, these pumps help keep sanitation systems running cleanly and consistently - mile after mile.

Key Features of Oberdorfer Aircraft Blue Water Pumps

Centrifugal Impeller Design

  • Features a single rotating metal impeller that draws liquid in at the center and expels it outward using centrifugal force.
  • Provides smooth, non-pulsating flow—ideal for sensitive aircraft plumbing systems.

Quiet, Non-Contact Operation

  • The impeller does not touch other pump components, resulting in low-noise, low-vibration performance.
  • Perfect for passenger environments where quiet operation is essential.

Safe Shut-Off Capability

  • Flow is not positive displacement, allowing the discharge line to be shut off without risk of overloading the motor or bursting lines.
  • No relief valve required, simplifying system design and reducing weight.

Compact and Lightweight

  • Designed for space-constrained aircraft systems.
  • Easy to integrate into lavatory service modules and blue water tanks.

Corrosion-Resistant Materials

  • Built with materials suitable for handling blue water solutions and disinfectants.
  • Long-lasting performance in high-altitude, high-humidity environments.

Typical Use Cases in Aviation

  • Commercial Aircraft Lavatories – Supplying blue water to flush systems and maintain hygiene.
  • Private and Business Jets – Compact, quiet pumps for luxury cabin sanitation.
  • Regional and Commuter Planes – Lightweight, efficient systems for short-haul operations.
