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.
