There are pvc, flat, canvas and more. Which is the correct hose material. Can anyone send a link to where to buy the proper hose?

I'm building a dredge with a homemade venturi suction nozzle with a 1.5 inch pressure hose going to the venturi inlet then outlet is a 2 inch . Using a 3500gph bilge pump powered by slow draining deep cycle batteries...
What type of hose is strong enough for 45 to 55 psi of water and rocks moving through it?
Any positive constructive criticism is welcomed!
