Priming systems for marine pumps

pump marine ejectors

Priming ejectors are widely used on ships to prime the centrifugal pumps when these are installed above the liquid level, when the low level in the suction tank in some circumstance is below the pump and when it is necessary to remove air formation inside suction pipes, due to infiltration from sea chest or from tank.

Typical applications are

  • bilge pumps
  • ballast pumps
  • stripping pumps
  • transfer pumps
  • other

Sometimes priming ejectors are applied also to volumetric pumps to prevent damages in case of very long suction suction pipes and large air volumes to evacuate.
