Key Features of Oberdorfer Fire and Ballast Transfer Pumps

High-Capacity Positive Displacement Flow
  • Rotary gear design delivers a consistent, pulse-free flow of water.
  • Flow rate is directly proportional to shaft speed, allowing for precise control in both fire suppression and ballast operations.
Self-Priming with Deep Suction Lift
  • Capable of lifting water from depths up to 20 feet (6 meters), enabling flexible installation across various vessel configurations.
  • Ideal for quick deployment in emergency situations.
Durable Marine-Grade Construction
  • Stainless steel shafts resist corrosion in harsh marine environments.
  • Self-lubricating carbon bearings reduce maintenance and extend service life.
Optional Built-In Relief Valve
  • Protects the system by relieving excess discharge pressure.
  • Automatically opens when pressure exceeds preset spring tension, preventing damage to the pump or piping.
Versatile Applications
  • Suitable for firefighting systems, ballast water transfer, bilge pumping, and general marine water handling.
  • Trusted by commercial, recreational, and industrial marine operators worldwide.
