Pumping, Dredging and Jetting Systems

Merlin Pump

  • Product Number: ITE-1028-DR-0040-00
  • The Merlin is an integrated eductor based excavation system which is designed to pump mud, sand, gravel, drill cuttings or shale without risk of blockage.

    A heavy duty cylinder operates a valve to reverse the flow at the nozzle to eject any object which may be causing an obstruction. A second cylinder operates a bypass valve to provide a powerful direct jet to break up heavy and cohesive seabed mud and sand prior to excavation.

    The pump may be configured to an intermediate position allowing combined use of suction and jettings. Both the impeller and eductor have been optimised for use on workclass ROV
