Sand Dredge Pump
Sand dredge pump has a wide flow channel and large blade design, which can continuously pump gravel or hard clay without clogging.
The high chrome alloy wet end parts make the dredge pump have excellent wear resistance and ultra-long life, which minimizes operating costs.
Kingda Sand Dredge Pump Features
Long service life
Kingda sand dredge pump is optimized for highly abrasive and sharp materials (sand, gravel, hard clay). It is made of high-wear-resistant metal materials such as high-chromium alloy and ductile iron, which greatly increases the wear resistance and impact resistance of dredge pump. The average service life is more than twice that of ordinary pumps.
No clogging
The impeller of sand dredge pump has been completely redesigned, with a larger impeller diameter and a reduced number of blades to ensure that larger solid particles can pass quickly, which makes the pump have a strong passing capacity and will not be blocked.
Optimum efficiency
At the beginning of the design, our engineers combined CFD hydraulic analysis and the wear-prone positions during the sand pumping process to improve and optimize by adjusting parameters such as blade width, blade type, and placement angle, and finally obtained a product with the best conveying efficiency.
Low total cost of ownership
The optional drive form makes Kingda sand dredge pump have a wider range of applications. It can be driven by a motor or a diesel engine. According to the actual location of the user's sand pumping project, the most efficient solution can be adopted, which greatly reduces the total cost of ownership.
Anti-pump cavitation
Kingda has designed a wider range of NPSHr to ensure that the sand dredge pump has strong suction capacity, which makes it have excellent anti-cavitation ability and can extract sand or soil at greater depth and higher concentration.

How does Kingda Sand Dredge Pump handle tough sand dredging?
First, during the operation of the pump, the high-pressure water provided by the high-pressure water pump causes the U-tube jet pump to produce a vacuum effect.
Then, the Pump sucks the mixture of sand, gravel, seawater, etc. through the sand spout, vacuum pipe, and inlet pipe and transports it to the cabin, the ground or sand washing equipment.
Finally, the cleaned sand can be used and stored as a building material or mineral resource.
Port maintenance
After a long period of seawater impact, a large amount of silt and sand will accumulate in the port or waterway. If the silt is not cleaned up in time, the port will not meet the transportation requirements and eventually cause port congestion.
Sand dredge pump can easily extract high-concentration mixtures of sand, silt, marine debris, etc., ensuring that the port or waterway has enough depth to accommodate ships.
Sand and gravel mining
In sand and gravel mining projects, it is often necessary to transport large particles, highly abrasive materials, etc. These large-diameter, sharp and hard materials require high-performance and stable pumps to transport.
Kingda sand dredge pump can transport sand and gravel for a long time without stopping for maintenance, ensuring the progress of sand and gravel mining projects and saving operating costs.
Construction sand transportation
In construction projects, a large amount of sand and concrete is required. The traditional transportation method is extremely inefficient, and the open air state during transportation will cause water loss, affecting the quality of the building.
The sand dredge pump has a strong suction and non-clogging ability to ensure that construction materials such as sand, concrete, etc. are quickly transported to the construction site, and the closed pipeline can ensure the quality of the materials.
Dredging
During the long-term operation of the river, a large amount of sand and silt will be deposited in the river, which will greatly affect the permeability of the river and cause the river to be blocked.
Sand dredge pump can quickly clean up a large amount of silt mixture, ensure the smooth flow of the river, increase the speed of construction, and save a lot of labor costs.
FAQ
Sand pump machine is usually used to pump sand, soil, silt or their mixture.
Sand pump machine includes sand pump and motor or diesel engine. It has the characteristics of anti-abrasion and can continuously transport abrasive materials such as sand and soil without maintenance.
Small dredge pump is generally used in working conditions with low flow and head requirements. It is smaller in size and easier to install.
The flow range of small dredge pump is 6-3200m³/h and the head is 3.5-80m.
