In addition, we also made the following improvements to the portable dredge pump. Our engineer designed a transition shaft and two bearing boxes, In this way, even if the diagonal pulling force is large, it only hurts the bearing and does not hurt the diesel engine crankshaft. If we connect the pump with diesel engine by V belt directly, the large diagonal tension may damage the clutch and the diesel engine crankshaft. However, for this dredge pump set, the power is large. Generally, this type of portable dredge pump connects with diesel engine by V belt, the speeds of the dredger pump and the diesel engine are adjusted by the belt and pulley. According to the customer’s working conditions, we recommended our 16-inch portable dredge pump for him. The sand discharge distance would be 300 meters all in the water. He required the sand output not less than 400 tons per hour, the dredging depth was not less than 15 meters. As there was no electric power source around, so the diesel engine was the ideal choice to drive the portable dredge pump. He wanted to buy a horizontal dredge pump to suck the sand from the river to fill the underground pipe. Qatar customer contacted us in June 2019.

This kind of dredger pump is designed with open impeller, so it has a large flow rate that is not easy to block. The portable dredge pump can be driven by diesel engine or electric motor according to customers’ request. The small dredger pump is widely used in rivers and lakes for sediment, sand, slurry or mud extraction applications. The centrifugal portable dredge pump has characteristics of high cost-performance, small structure, easy operation, easy transportation, and convenient maintenance. This type of portable dredge pump is commonly used in sand pumping systems to move sand deposits to a short distance no more than 300 meters. The high speed impeller is engineered for the portable dredger pump to create a huge suction power and the high-efficiency sand suction work can be achieved. Portable dredge pump is designed to extract small particles of sand sediment.
