![]() The Mini dredge pump is equipped with an oversized silicon carbide shaft seal. A leaky shaft seal will disable your pump completely, by allowing air to enter the pump case instead of water being drawn up the suction hose. The shaft seal is the component that seals the engine shaft as it enters the pump case. Carbon/ceramic is the cheapest seal material there is and is a strong indication that your pump is designed to pump water only. Cheap trash pumps usually utilize small diameter carbon/ ceramic shaft seals. ![]() The agitator water jet system is necessary to deliver kinetic energy (energy of motion) to the sediment to take it from a solid state rendering it a fluid slurry.Ĭheap trash pumps are not designed to withstand abrasion or shock. On the other hand, this unit will provide you with the means to renew the quality of your waterfront, and the quantity of removed sediment will be limited only by the amount of time & energy that you put in to it.First of all, a self priming pump alone is not very effective in removing sediment. Even expensive industrial dredges can’t do that. The mud is not going to come out of your discharge hose looking like toothpaste. You are also going to have to be prepared to deal with the fact that you will be pumping a lot of water along with the sediment. If you are cleaning a modest area, such as around a dock or boat slip, you can expect to get the job done relatively quickly. These volumes may vary depending upon the nature of your sediment, distance pumped, and your energy & skill level, but many operators state that they are able to pump a much larger volume than our estimates. The excavation capability of our dredger is about 60 cubic meter of water per hour, along 6 cubic meter of sediment per hour. Our suction dredger is particularly effective in removing sand, silt, and that fluffy black stinky mud that ruins the waterfront and prevents one from enjoying beach and water activities.
