Hydraulic piston pumps are suitable for a variety of high viscosity, solid particle containing, corrosive, or high-pressure materials due to their characteristics of high-pressure conveying, wear resistance, and stable flow rate. The following are the common types of conveyed materials and specific examples:

　　1、 Mineral slurry materials

　　This type of material usually contains a large amount of solid particles (such as ore debris and mineral particles), with a high concentration, and requires high-pressure transportation to meet processes such as beneficiation and tailings treatment.

　　Metal ore slurry: iron concentrate slurry, copper concentrate slurry, lead-zinc slurry, gold ore slurry, etc.

　　Non metallic mineral slurry: kaolin slurry, graphite slurry, quartz sand slurry, talc slurry, fluorite slurry, etc.

　　Tailings slurry: Tailings slurry produced after mining (containing various mineral residues with significant differences in particle hardness).

　　2、 Mud materials

　　Including natural mud or high viscosity, impurity containing mud generated in industrial production, it needs to be stably transported to processing equipment (such as filter presses, sedimentation tanks).

　　Construction/Engineering Mud: Shield tunneling construction mud, drilling and grouting pile mud, river dredging mud, etc. (including sediment and gravel particles).

　　Municipal sludge: Concentrated sludge and dehydrated sludge from sewage treatment plants (containing organic impurities and a small amount of solid particles).

　　Ceramic slurry: Raw material slurry used in ceramic production (containing clay, quartz sand and other particles with high viscosity).

　　3、 Chemical materials

　　Some chemical raw materials or intermediate products that are corrosive and contain solid particles require corrosion-resistant and wear-resistant pump structures for transportation.

　　Granular chemical slurry: phosphate slurry, pyrite slurry in fertilizer production, pigment slurry in the dye industry, etc.

　　High viscosity chemical materials: certain resins, adhesives, and semi-finished coatings (high viscosity, requiring high pressure to drive flow).

　　4、 Other special materials

　　Food/pharmaceutical industry: Some materials containing solid particles (such as certain traditional Chinese medicine residue slurries and food processing residue slurries, which require pump body materials that meet hygiene standards).

　　Metallurgical industry: slag slurry and metal waste slurry generated during the smelting process.

　　Summary

　　The core advantage of hydraulic piston pumps lies in their ability to handle materials with high pressure, high concentration, and solid particles, especially suitable for transportation scenarios in industries such as mining, metallurgy, ceramics, municipal engineering, and chemical engineering. The specific applicable materials need to be further matched with the material of the pump (such as ceramic plunger wear resistance, special alloy corrosion resistance) and parameters (pressure, flow rate).
