Robust excavation pump design that will not block or jam
Like all Tritech excavation 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.
The new 35 – 60 h.p. Merlin excavation pump is the must have successor to the Excalibur. Merlin incorporates many of the improved design features introduced on the small Super ZipJet pump which has proven to be so successful.
The pump is smaller, lighter and more robust with greater performance in both excavation and jetting functions. It features the same double seal arrangement as the Super ZipJet and a modular design provides great ease of maintenance.
There are significant efficiency increases in both the impeller and educator making this the tool that no WROV should be without.
