Hydraulic dredge pump is a type of sand pump installed on the excavator’s arm and driven by the hydraulic system of the excavator. It is divided into several series and specifications according to the outlet diameter, such as 12 inches, 10 inches, 8 inches, and 6 inches. It is mainly used as an attachment to the excavator. It is widely used in where a lot of water, silt, sand, and gravel are too thin to be excavated and inconvenient to transport by vehicle. The hydraulic sand pump is used for extraction operations, greatly improving work efficiency. It is widely used in inland waterway dredging projects, port silt treatment, tailings pond sand pumping, ore dressing, municipal sewer silt removal, etc.
Excavator Hydraulic Dredge Pump Working Principle
- The hydraulic dredge pump is powered by a hydraulic system and uses a motor as an actuator to convert hydraulic energy into mechanical energy.
- During operation, the energy is transferred to the slurry medium through the rotation of the pump stirring impeller, which produces a certain flow rate, drives the flow of solids, and realizes the transportation of slurry.
- The hydraulic motor uses the famous domestic quantitative plunger motor, which has the characteristics of advanced and reasonable structure, good performance, high efficiency, and stable operation.
- Hydraulic pump station drive, the hydraulic motor used in this pump is suitable for small, medium, and large series of hydraulic pump stations.
Product Advantages of the Sand Suction Pumps
- The hydraulic transmission has small inertia and fast reaction speed, and can achieve a wide range of step-less speed regulations;
- It can automatically realize overload protection, and there is no burning motor phenomenon;
- The solid concentration of mortar, mud, slag, etc. extracted is high, which can reach more than 70%;
- Hydraulic dredge pump can be connected to machines with hydraulic systems such as excavators to achieve free transfer, especially in remote areas of construction, power shortage, the advantage is more obvious;
- It can be used as an accessory of the excavator to extract and transport over long distances when digging is unfavorable, thereby improving the value of the excavator itself.
Main Application of Excavator Dredge Pump
- Sand pumping, dredging, and silt removal in ports, rivers, lakes, etc.
- Draining silt and mud in engineering construction, draining water and silt during bridge pier construction, extracting silt, gravel, etc.
- Discharging slag, slurry, and all solutions containing solid substances in iron ore, tailings ponds, and concentrators.
- Hydraulic dredge pump is used to absorb high-concentration tailings, waste slag, high-temperature iron slag, iron filings, etc. in metallurgy, steel, and other industries.
- Emergency drainage, cleaning up post-disaster silt, etc.
How to Select the Proper Hydraulic Dredge Pump
- Confirm the required head, flow rate, conveying distance, etc. according to the actual working conditions of the user.
- Check the excavator parameters to find out the displacement, pressure, and other parameters of the excavator hydraulic system.
- Select the hydraulic motor model based on the above information.
- Calculate the actual output power of the excavator hydraulic system and select the appropriate hydraulic dredge pump.
