How does a suction nozzle work?
The answer is that a device is used to convert the pressurized water discharged from the pump into a vacuum. This device is called a suction nozzle and is attached at the far end of the material hose. A vacuum is created which sucks up water and gravel, pushing the material through the hose.
How does a small gold dredge work?
Suction dredges utilize a high-pressure gasoline powered water pump to suck up water, gravel and gold, and inject this material into a sluice through a header box. The header box dampens the rush of water and gravel so that it flows evenly into the sluice. The sluice captures the gold behind the riffles.

How do you make a water pump out of a pipe?
To create the pump section, take the 24″ long 1/2″ pipe and pit the 1/2″ elbow on one end. Then put the 1-1/4″ cap with the hole drilled in it over the pipe. Then, place the 1/2″ slip to 1/2″ thread bushing onto the end. Take the pipe insulation and place it over the threads, then screw on the 1/2″ cap. This creates the seal needed for the pump.
