Sand Gravel Pump, Electric Dredge Pump, River Dredge Pump

Sand gravel pumps are suitable for many operations, including sand, gravel, and rock suction, sand mining, sediment pumping, and metal smelting slag transportation. They are widely used in a variety of settings, including reservoirs, lakes, rivers, and the sea. Their highly variable nature requires them to be versatile, hardy, and able to withstand many types of media under potentially harsh conditions.

Dredge pumps are generally used to simulate the principle of water flow scouring in nature. The sand gravel pump creates high pressure in the water, passing through it and is used to carry out sand and soil digging. The high-speed water column impacts the soil and sand, wets and disintegrates it, and mixes into the mud, which is then lifted by a vertical sand suction pump and transported to the sand field through a pipeline.
