Here's a video showing the 4" manual gold pump I've made filling a classifier in literally 60 seconds. Using a standard 2 1/2" pump would never fill a classifier this quickly regardless of the type of material available, the 4" is just a suction monster when it comes to shifting material quickly. The 4" gold dredges barely ever get stuck with rocks due to it;s size as most stones will easily fit in the tube that would block up most smaller gold pumps & gold dredges. You can see in the video it only takes 4 pumps on the dredge to fill the classifier and the video then goes on to underwater shots of the pump so you can see the material it shifts and the suction it creates. Due to UK panning laws, powered equipment is not allowed so we have to make do with the equipment we can use that works and by scaling up said equipment, it means more material can be moved and worked in the same time.
