ZJ Slurry centrifugal pump

ZJ slurry pump is a horizontal, single stage, single suction, cantilever double shell structure, widely used to transport slurry containing solid particles. The maximum volume concentration of solid mixed liquid Cv ≤ 30%, weight concentration Cw ≤ 60%, flow path is smooth, and flow capacity is strong. Seen from the pump inlet, it rotates counterclockwise. The pump outlet can be installed by rotating at 8 different positions at 45 ° intervals.

Discharge end size: DN=25 to 300mm

Flow rate: Q=44 to 2200m3/h

Head: H=16 to 116m

Speed:  n=490,590,740,980,1480r/min

Scope of application

Mine: Black and nonferrous ore pulp feed pumps and various concentrates, tailings slurry transportation, etc.

metallurgy: transportation of various slurries (including high-temperature slurries, ≤ 106 ℃) in aluminum plants, transportation of various slag slurries in steel plants, etc.

Coal: coal mining, transportation of various coarse and fine coal slurry (middling coal, clean coal, etc.).

Electric power: ash removal and flushing in power plants, transportation of various ash residues and mortar, etc.

Building materials: transportation of various mud containing mortars (such as cement plant slurry), etc.

Chemical industry: Chemical industry (such as phosphate fertilizer, potassium fertilizer, etc.), transportation of various abrasive and corrosive slurry, etc.

Environmental protection: transportation of abrasive and corrosive slurry for flue gas desulfurization (FGD).

Water conservancy: dredging of lakes and rivers, suction and discharge of silt, gravel, and high plastic clay.

Sealing instructions:

2.1 Packing seal:

For pumps with a lift H ≤ 0.5MPa, packing can be used for sealing. The packing should be made of wear-resistant and scouring resistant carbon fiber material, and the shaft sleeve should be washed and cooled with external clean pressure water to prevent slurry particles from entering the shaft sleeve and packing, extending the service life of the packing seal. The external water pressure is the pump outlet pressure+0.1MPa, and the external water flow rate is 1-2 m3/hour. For small pumps, take the small value, and for large pumps, take the large value.

Auxiliary impeller+packing seal

For pumps with a lift of 0.4MPa ≤ H ≤ 0.8Mpa, auxiliary impeller+packing can be used for sealing. The packing should be made of wear-resistant and scouring resistant carbon fiber material, and the shaft sleeve should be washed and cooled with externally connected clean pressure water to prevent slurry particles from entering the shaft sleeve and packing. Extends the life of the packing seal. The external water pressure is 0.7 times the pump outlet pressure, and the external water flow rate is 1-2 m3/hour.
