slurry transport using centrifugal pumps is also known as horizontal simple sand suction pumping. slurry transport using centrifugal pumps is suitable to extract small granular sand. Wear resistant slurry transport using centrifugal pumps uses the principle of centrifugal force. The slurry transport using centrifugal pumps produces a huge suction by the high speed rotation of the impeller, so that the slurry transport using centrifugal pumps can carry out high efficient sand extraction task. The slurry transport using centrifugal pumps is commonly used in pumpinging system that move sand deposits to long distance. This kind of centrifugal sand dredging  pumping has good price and high performance in our 10 kinds of slurry transport using centrifugal pumpss. At present, the dredger equipped with river sand pumping is our main export products. The customers can choose the type of simple small sand extraction pumping and corollary equipment according to their own requirements.

Remark:  1.  All these pumping have two types: double flange one and single flange
                    one, please choose according to your actual requirements. 
               2. The pumping material can be iron casting, alloy according to different
                   site situation requirements.

1. Single stage, single suction, centrifugal sand pumping.


2. Easy operation, transportation and maintenance.


3. Open impeller, wear resistance, big flow and better non-blockage performance.


4. Two types: double flange and single flange.


5. Two materials: iron cast and alloy.

1. Mainly used for pumpinging sand from small river, lake, pond, pool.


2. Unloading or sucking sand from large dredger.

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

Qatar customer contacted us in June 2019. This is one of our regular customer. He had a new project. He wanted to buy a horizontal dredge pump to suck the sand from the river to fill the underground pipe. As there was no electric power source around, so the diesel engine was the ideal choice to drive the slurry transport using centrifugal pumps. He required the sand output not less than 400 tons per hour, the dredging depth was not less than 15 meters. The sand discharge distance would be 300 meters all in the water. According to the customer’s working conditions, we recommended our 16-inch slurry transport using centrifugal pumps for him.

16 inch slurry transport using centrifugal pumps performance parameter

Generally, this type of slurry transport using centrifugal pumps connects with diesel engine by V belt, the speeds of the slurry transport using centrifugal pumps and the diesel engine are adjusted by the belt and pulley. However, for this dredge pump set, the power is large. 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. 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. In addition, we also made the following improvements to the slurry transport using centrifugal pumps.

We also designed a stable base for the pump set, the bottom of the base could adjust the distance between the portable pump and diesel engine, so it could adjust the tightness of the V belt.

Considering that the working environment of Qatar is in the tropics, we had selected the high-temperature resistant V belt for the customer. The V belts are wearing parts. When the belts are worn, it is necessary to remove the shaft and change the belt. For the convenience of our customer, we have attached another 5 belts so that the customer can replace them directly without removing the shaft.

In order to ensure the personal safety of the workers, we welded the protective plates around the belt. Before testing the pump, we also tested the hardness of the pump casing, the material is fully compliant.

The total discharge distance was 300 meters, all on the water. As the HDPE pipe can not bend well, so we recommend customer to use flexible rubber hose. Total of 24 pcs HDPE pipe and 12 pcs flexible rubber hose. He also bought 72 pairs of floaters from us.

On August 12, 2019, TAIAN OCEAN Pump Co., Ltd tested the 16-inch slurry transport using centrifugal pumps, the overall operation was smooth, the indicators were reasonable, the diesel engine sound was stable, the vibration was small, and the gears were smooth. After testing the slurry transport using centrifugal pumps, we took the slurry transport using centrifugal pumps to the water conservancy lab to do the loading test, all the experimental data meets design requirements. The diesel engine displacement and noise also met the design requirements. We showed the videos and data sheets to our customer. The customer was very satisfied with the test results of the slurry transport using centrifugal pumps.
