Newbie here with a possible stupid question

[jpitt1970]

Long story short, I have acquired several Honda 5.5hp engines with almost zero hours on them, along with several Hypro 5200 series twin piston pumps.

Is it possible to rig up a piston type pump to make a suction dredge, or do I need to use a centrifugal pump? I have never seen a dredge in person and I am very new to prospecting, but really want to build myself something better than the simple sluice I currently have.

Also, if anyone is interested, I have 6 of the Hypro 5200 pumps for sale @ $200 each and 4 Honda Gx160 5.5hp engines for sale @ $200 each

sorry but water dont compress.

I can picture a compressed air suction nozzle for desert dredging into a drywasher
If only I lived close to a desert

There are piston pumps for water. Most are for pressure applications like pressure washers. The GPM is low and would not work for a dredge.

I've actually tested my fluid bed prototype as an air dredge. It works! Now if the shop would get on making it from aluminum...

What you probally have is called a POSITIVE DISPLACEMENT PUMP and is utilized for pumping water up to much higher elevations. I've used them many times before and EXTREMELY expensive and very useful. Not a lot of volume but for filling catch basins,water tanks or setting up a gravity dredge system from a cistern or water tower will work just mightyfine. Works like a any gas engine with intake valves and outflow valves ifn' that's what ya got........John

Good job Nick!

Ask and you shall receive,as I said prior,they're positive displacement and will work miracles as will pump straight up a canyon wall,have a ball-John
