1. Large Particle Suction Pump Overview
Large particle suction pump, also known as the gravel pump, is mainly used for the long-distance transportation condition of the strong abrasive material which is too large to be transported by the general sand pump. The large particle sand pump is suitable for dredging, sand pumping, sand mining and metal smelting and blasting. Because of its good performance, the large particle suction pump is also widely used in dredging and dredging in inland rivers.
2. Application Cases of Large Particle Suction Pump
Mr. Zeng, from Indonesia, had been engaged in river sand mining projects all the year round. The sand suction pump used before was made of ordinary cast iron, which had poor wear resistance and low efficiency of sand discharge. And the sand in the local river is coarser and has pebbles. The sand pumps made of ordinary materials could not withstand the impact of large particles, and were easily worn or even damaged. Mr. Zeng was introduced to our factory by his friend. After understanding the situation on the spot, the technicians recommended a 12 inch large particle suction pump as the main pump for sand suction.



This 12 inch large particle suction pump is made of high-chromium alloy wear-resistant material. Moreover, the main casing of the sand pump and the main over flow components such as the impeller guard plate are thickened, which are particularly suitable for the conditions of extracting coarse sand and large particles. Secondly, the sand pump has good pass-ability, and has three blades, and the maximum discontinuity can reach 22 cm through the particles. Generally, no blockage occurs even if the pebbles are slightly larger, so they will not get stuck.
Mr. Zeng was very interested in this 12 inch large particle suction pump, he immediately signed a contract and paid the deposit. There was a 450 hp diesel engine at the construction site, which could drive the sand pump. However, the hull space was limited and the matching gearbox connection space was blocked, so the engineer recommended that the pump and the engine could be connected through the pulley. The on-site master informed the technicians the diameter and size of the diesel engine end shaft. The technicians selected the D-type 10-slot pulley for the sand pump according to the matching diesel engine power. After determining the specific plan, the workshop organized the production and delivered it to the customer within the specified time.

- A sand suction pump is a pump used to suck up mud, silt and other solid particles. It is widely used in the following fields:
4.1 River desilting: Sand suction pumps are used to clean up silt in rivers, estuaries and ports to ensure smooth waterways, prevent flooding and maintain the passage of ships.
4.2 Marine engineering: In marine engineering, sand suction pumps are used to build ports, docks, seawalls and other marine infrastructure.
4.3 Mineral sand mining: During mineral sand mining, sand suction pumps can be used to suck mineral sand and ore from water for subsequent processing.
4.4 Coastal engineering: Used in coastline protection and beach restoration projects to help protect the coastline from erosion.
4.5 Sewage treatment: In sewage treatment plants, sand suction pumps can be used to transport wastewater or sludge containing solid particles.
4.6 Mud transportation: In industrial production, sand suction pumps can be used to transport mud and other solid particle suspension liquids.
