Vertical Sand Pump

The vertical sand pump is a centrifugal slurry pump with a vertical suspension structure. The motor drives it directly through a coupling.
The pump body works submerged in the liquid and does not require water filling for water intake. It starts and pumps immediately.
It is specifically designed for transporting abrasive media containing solid particles, such as sand, slurry, tailings, coal slime, etc.
It can handle high-concentration materials with a solid content of up to 70%, and has a strong particle conveying capacity.
It is widely used in industries such as mining, metallurgy, coal, power, and construction materials.

Vertical structure, immersion installation
The pump body is vertically immersed in the liquid, occupying a small space and easy to install.
No bottom valve or vacuum assistance system is required, making the operation convenient.
The liquid depth can be customized according to the working conditions, reaching up to several meters at the deepest.
High-chromium alloy wear-resistant parts
The impeller, guard plate, and volute are cast with high-chromium alloy, which is hard and wear-resistant.
Stainless steel, duplex steel, etc. can be selected as materials to deal with corrosive media.
The service life of the flow components is long, reducing the frequency of replacement.
The shaft seal is reliable and maintenance is simple.
A combination of auxiliary impeller power seal + packing seal is adopted, with little leakage.
The bearing seat is independent of the pump body and does not come into contact with the medium, with a long service life.
It is easy to disassemble and assemble, and daily maintenance only requires checking the lubrication of the bearings.

Dewatering and pumping in the beneficiation plant: from the ball mill discharge, from the classifier return sand, from the cyclone feed, ZJL/GL vertical pumps operate directly in the tanks
Tailings transportation: pumping from the front of the tailings dam, dredging of the tailings pit
Drainage of underground tunnels: water accumulation in the mining points + mixed pumping of water and slurry
Wastewater treatment plant: cleaning of the oxidation ditch sedimentation tank, sludge discharge, sand and silt discharge from the sedimentation tank
Municipal sewage: suction of flowing sludge, mud, and sand from urban sewage channels
Pumping of concentrated liquids, thick oils, oil residues, and turbid liquids in industries such as chemical plants, steel smelting, papermaking, cement plants, food factories, and dyeing
Dredging of inland rivers, construction of coastal embankments, pumping of mud and sand from rivers, lakes, reservoirs
Combined with high-pressure water pumps to form a hydraulic excavation and filling unit: high-pressure water column disperses soil and sand → vertical sand pump lifts → pipeline transportation to the sand yard
Sediment removal, embankment construction, low-lying area renovation, and basic construction of farmland in lakes and rivers
Unloading of sand by dredging ships, excavation of tidal flats for aquaculture
Pumping of sand by dredging ships, extraction of sand and stone slurry from sand washing plants

Q: How to choose between vertical sand pumps and horizontal ZJ slurry pumps?
A: Narrow space, need submersible pumping of sludge, deep pits/pond bottoms/pit interiors → vertical sand pumps; seeking high flow rate, easy maintenance, fixed-position operation → horizontal ZJ pumps. In simple terms: when the medium needs to be pumped up from below the liquid surface → vertical; when the medium needs to be smoothly or vertically conveyed above the liquid surface → horizontal.
Q: Can the submersion depth be customized?
A: Standard ZJL series: 0.9 - 4.5 m. GL series can be customized according to the depth of the pool. The standard length of the fixed-position vertical slurry pumps is 0.5 - 10 m. For depths over 10 m, special design is required (add guide bearings, long shaft segmented).
Q: What is the use of the impeller with a stirring blade?
A: Adding a stirring blade below the main impeller can stir the sludge at the bottom of the water into a turbulent state and then pump it out. It is mainly used for "sludge pit cleaning, sludge pit pumping, riverbed sand removal" - without the stirring blade, the sludge at the bottom of the water cannot be reached by the main impeller and cannot be pumped up.
Q: What to do if the medium is corrosive?
A: Select SPR/LPR type (rubber lining) for non-edge corrosion-resistant slurry (such as chemical waste liquid, slurry); or use all stainless steel 304/316/316L materials. The metal type SP is only suitable for abrasive slurry, for strong corrosion, lining or material replacement is required.
