2019-6-15  In any dredge, you will have 2 types of suction devices; either a suction nozzle or a power jet. A suction nozzle only works with higher pressure pumps. The recommendation is a minimum of 140-foot head lift for a suction nozzle. A power jet can run at a slightly lower head lift at a 130 foot, however it does require higher volumes.

Suction Jet Assist – WillardSays

Suction jet assist makes the equivalent of an extra 10 or 15 inches of effective vacuum available at the dredge pump inlet. Effective vacuum is the total amount of vacuum that can be utilized to raise solids up to the pump inlet port. More is better. Consider for example, a dredge that is maintaining 20 to 22 inches of vacuum without a jet ...

However, the mathematics which describe the operation of the nozzle takes some careful thought. As shown above, nozzles come in a variety of shapes and sizes depending on the mission of the aircraft.

2021-9-6  Abrasive nozzle selection. As a general rule, the diameter of the orifice for the abrasive nozzle should be approximately three times the water nozzle orifice. Some people would suggest using a smaller ratio, about 2.5 times. Using a smaller ratio does produce faster cutting speeds. The trade-off is increased nozzle wear and costs.
