A sand slurry pump is a heavy-duty centrifugal pump specifically engineered to transport mixtures of sand, gravel, and water-known as slurry-without rapid wear or clogging. Unlike standard clean-water pumps, it features thick, abrasion-resistant wet-end components (including the impeller, casing liner, and throat bush) made from high-chrome alloy or rubber. These materials withstand the constant sandblasting effect of solid particles moving at high velocity through the pump.
CZME sand slurry pumps can handle solids concentrations up to 65% by weight, particle sizes up to 25 mm, and flow rates ranging from 50 to 3,500 m³/h. This makes them the workhorses in sand mining, river dredging, mineral processing, and aggregate washing plants around the world.
Core advantage
3× Longer Wear Life
Wet-end parts are cast from A05 high‑chrome alloy (27% Cr) with a hardness of HRC 60. In quartz sand applications, our impellers last three times longer than standard cast iron parts, significantly reducing your spare parts cost per ton pumped.
No Clogging, High Solids Passing
Wide flow channels and large sphere‑passing capability (up to 25 mm) allow coarse sand, shells, and small gravel to pass straight through - eliminating downtime for blockage clearance.
Interchangeable with Warman® Standards
Dimensions and wet‑end parts are fully interchangeable with international standard slurry pumps (AH / SP / G series). You can replace your existing pumps or parts without modifying piping or foundations.
Factory‑Direct with OEM/ODM
Buy directly from our Ningbo factory - no middlemen. We offer custom materials, flange standards (ANSI / DIN / IS), voltages, and branding options. Typical lead time: 7–15 days for standard models.
Structure & Design Features
Impeller: Closed type with pump-out vanes that reduce seal pressure and extend gland life. Semi-open design also available for coarser solids.
Casing: Split outer casing with replaceable liner - simply replace the worn liner instead of the entire casing.
Throat Bush & Frame Plate Liner: Bolted in place and replaceable on-site in under 2 hours.
Shaft Seal Options
Gland Packing Seal - simple, low-cost, requires flush water
Expeller (Centrifugal) Seal - no flush water needed, ideal for water-scarce sites
Mechanical Seal - zero leakage, suitable for environment-sensitive projects
H3: Bearing Assembly
Oversized shaft with short overhang minimizes deflection. Grease-lubricated, double-row roller bearings are housed in a removable cartridge - the entire assembly can be swapped in the field without realignment.

Sand Slurry Pump FAQ
What is the difference between a sand pump and a slurry pump?
A sand pump is a specific type of slurry pump optimized for granular, settling solids such as sand and fine gravel. General slurry pumps cover a broader range of applications, including tailings, sludge, and chemical slurries. Sand slurry pumps typically feature wider flow channels and thicker high‑chrome wear parts to withstand the sharp, fast‑settling nature of sand.
How long does a sand slurry pump impeller last?
It depends on sand sharpness, concentration, and pump speed. In typical river sand duty at 40–50% concentration, a CZME A05 high‑chrome impeller lasts 2,000–4,000 working hours. Running the pump at a lower speed with a larger model can double the wear life.
Can your sand slurry pumps run with a diesel engine?
Yes. We supply complete diesel‑driven pump sets including clutch, base frame, and control panel - widely used for river sand mining and remote dredging sites without grid power.
What is the maximum sand concentration the pump can handle?
Up to 65% solids by weight for our heavy‑duty series. For sustained operation, we recommend 40–55% for the best balance of throughput and wear life.
Are your pump parts interchangeable with Warman® pumps?
Yes. The wet‑end parts (impeller, liners, throat bush) of our standard series are dimensionally interchangeable with Warman® AH, SP, and G series pumps. You can use CZME parts directly on your existing pumps.
What is the price of a sand slurry pump?
Prices range from US$800 for 2‑inch models to US$50,000+ for 16‑inch heavy‑duty sets, depending on size, material, and drive type. Send us your duty data and we will provide an exact factory‑direct quotation within 24 hours.
