Can I just build a dredge out of a trash pump

18.07.2009· The problem with trash pumps is they don't have the lift or GPM as some of the other high end pumps/engines. I've seen many of these trash pumps and they never seem to have the lift when you're down 5+ foot underwater. With the pump you mentioned you might be able to run a small 2-inch, maybe 3-inch, but it could be iffy. Hope this helps, Rob

Suction Gold Dredge Basics - Steve's Guides

A gold dredge is powered by a motor and pump. A common misperception is that gravel is sucked through the pump.

First, gravel pumps are very expensive, heavy, and high maintenance items. Second, a 2

Pumps Semi Trash vs High Pressure – Common

There are two types of pumps. Semi trash pumps and high pressure pumps. (HP often referred to as clear water.) Semi trash pumps will move large amounts of water with not too much PSI. Most 2" semi trash pumps are rated about 35 - 42 psi. Rocks, sand and gravel, up to about 1/4" - 1/2" can pass through these based on the pump.
