A Koshin Diaphragm Pump is great for pumping sludge and gravel. These pumps are built to run dry and are also perfect for areas of low seepage. Koshin Diaphragm Pumps are  great for construction sites and also other situations in which the pump will need to be run for sustained periods of time. The KDP-50X and KDP-80X are two of the best Diaphragm pumps on the market. You will not go wrong with either of these pumps.
