What causes of Low Sand Concentration of 10-inch Sand Pump?

Submersible sand dredge pump is also renamed as heavy duty agitator pump, submersible sand pump, submersible dredge pump, or submersible sludge pump.
A Chinese sand pump customer called our company to inquire about a 10-inch sand pump, intending to replace his current sand pump. The specific reason is that the customer is very dissatisfied with the current sand pumping concentration. The customer is using a 10-inch sand pump (10 in and 8 out) produced by a certain manufacturer. The conveying distance is 200 meters, and the sand output is 20-40 cubic meters per hour. The amount of sand is only about 10%.
In this case, replacing the sand pump is simple, but the most important thing is to find the root cause of such low sand content in order to completely solve the problem. The reason for the low concentration of sand pumping is the site or the unreasonable configuration of the sand pumping pump. If it is caused by the site, then the role of sand pump is not great.
Learned about his construction site and equipment configuration from the customer in detail. The water depth of the sand pumping site is more than 1 meter, and the sand layer is about 5 meters. The sand is medium-coarse sand, and the sand layer is not very hard. It is impulsive with high-pressure water energy. It is equipped with a diesel engine with 1500 rpm and 250 hp horsepower.
The water volume at the outlet of the pipeline is relatively sufficient, which eliminates the possibility that the pump's flow rate is too small due to the long distance of delivery, and the pipeline has subsidence, resulting in less sand.
DOS multi-purpose 10-inch sand pump,
The high-pressure water pump used by the customer is 80 cubic meters per hour, 22 meters head, 7.5kw motor, and single nozzle. For a sand pump with 10 inches in and 8 inches out, the head of this 7.5kw high-pressure water pump is too low, and the pumped water has no power. It is recommended to replace the high-lift high-pressure water pump. The number of single nozzles is also small, at least with 3-4 gun heads, so as to take care of the sand in all directions and wash up more sand.
In summary, the biggest reason that affects the concentration of sand pumping may be that the high-pressure water pump configured by the customer is too small. It is recommended that the customer replace the high-pressure water pump with a larger flow rate and make more gun tips.
After the customer replaced the 22kw high-pressure water pump, the sand content increased significantly, and the sand output could reach about 80 cubic meters an hour.
