Merlin
The 35 h.p. - 60 h.p. Tritech Merlin dredge pump is the successor to Tritech’s Excalibur pump, it includes improved design features as introduced on the smaller Super ZipJet dredge pump.
The Tritech Merlin is smaller, lighter and more robust pump with greater performance in both excavation and jetting functions. It features the same double seal arrangement as the Super ZipJet dredge pump and its modular design provides great ease of maintenance.
There are significant efficiency increases in both the impeller and eductor making this the tool that no work-class ROV should be without. As with all Tritech pumps, the Merlin will not block or jam because there are no moving parts in the suction flow path.
The flow reversal valve can be operated to back flush the suction nozzle should there be an obstruction. Power is derived from a stream of high velocity fluid creating a low pressure region behind the suction nozzle.
The pump may be rapidly switched from suction to jetting, or be configured to an intermediate position allowing jetting and excavation to be carried out simultaneously.
