Types of Metal Slurry Pumps & How to Choose Among 4 Products
Metal slurry pumps are mainly used to transport abrasive slurries containing ore particles, tailings, sand, froth, or other solids. Their wet ends are usually made of metal materials suited to specific wear, impact, or corrosion conditions.
Currently, metal slurry pump series include CSP sump pumps, CAH/CHH heavy-duty slurry pumps, CAF froth pumps, and CZQ submersible slurry pumps. Products vary by installation, media, and application location.
CSP Series Sump Pumps
CSP series sump pumps are mainly used in tanks, slurry pits, sumps, and other submerged installations. Part of the pump extends into the medium; selection requires verifying insertion depth, liquid level changes, tank dimensions, and bottom sedimentation.
CAH/CHH Heavy-Duty Slurry Pumps
CAH/CHH heavy-duty slurry pumps are designed for highly abrasive, high-solid, or continuous-transfer slurry conditions. Selection depends on flow rate, head, particle size, solid content, and piping system.
Specific differences between CAH and CHH should follow company performance curves and model specifications, not just model letters.
CAF Series Froth Pumps
CAF series froth pumps handle slurries containing froth or high air content, such as flotation froth. Key factors include gas content, froth stability, liquid level changes, and process flow rate.
CZQ Submersible Slurry Pumps
CZQ submersible slurry pumps operate directly submerged in liquids or slurries, ideal for pit discharge, settling pond cleaning, construction desilting, and mobile pumping. Selection requires checking submersion depth, cables, power supply, particle size, and piping.
How to Choose?
Consider the CSP series for submerged tank or sump pumping; CAH/CHH series for heavy abrasion, high solids, or continuous transfer; CAF series for frothy or aerated slurries; and CZQ submersible pumps for direct underwater installation or mobile discharge.
Final model selection depends on flow rate, head, particle size, solid content, density, temperature, installation method, and operating time.
