In municipal, mining, metallurgical, power, dredging and other industries, slurry pumps serve as the “core conveying equipment,” directly determining the continuous operation efficiency and maintenance costs of production lines. Choosing the right pump can achieve three years of major repair‑free operation and precise energy consumption control; choosing wrong can easily lead to frequent shutdowns for part replacements, soaring maintenance costs, and even dragging down the entire production line!
As a professional manufacturer deeply involved in the industrial pump sector, Shijiazhuang Boda Industrial Pump Co., Ltd. leverages years of industry experience and integrates core technical resources to bring you this “full‑of‑substance” Slurry Pump Selection Guide. From basic logic to practical steps, even beginners can directly apply it. Moreover, the company’s star products precisely adapt to different scenarios, helping you avoid selection pitfalls and choose efficient equipment that is “tailor‑made” for your needs!
Three core selection criteria
Medium + Operating Conditions + Parameters
•Solid‑Liquid Ratio & Particles: Solid content, particle size (>5mm is considered large particles), and hardness directly determine the pump type and flow passage design. For slurries with large particles, high hardness, and high concentration, the company’s heavy‑duty slurry pumps are recommended; for fine particles and low‑concentration media, powder transport pumps are more suitable to reduce operating costs. A weight concentration Cw=30% serves as a dividing line.
•Corrosiveness: Accurately match according to pH value and chloride ion content. For pH≥4, conventional high‑chromium alloy, ceramic, rubber lining, polyurethane and other materials can be used. For pH<4, comprehensive judgment is required. Chloride ion content Cl⁻ ≥5000ppm generally requires materials such as A49, Cr30, or ceramic.
•Temperature & Viscosity: High‑temperature (>120°C) scenarios are paired with the company’s high‑temperature‑resistant materials and sealing components to avoid seal failure. High‑viscosity slurries require dedicated low‑speed pump types, simultaneously increasing head margin to ensure conveying stability.
•Abrasiveness: For slurries containing high‑hardness particles (such as iron ore sand), both metal and non‑metal materials are feasible, but the final material must be determined in combination with other medium characteristics – it cannot be explained in one sentence. For weakly abrasive slurries, special impeller materials can also be used to avoid over‑investment.
Different operating environments and process requirements greatly influence pump type selection. Focus on these four points:
•Installation Space: For ample space, choose horizontal pumps with CRz or ZVz transmission for easy maintenance. For confined spaces, use CV/CVL horizontal pumps, or if immersion is required, prioritize VSC vertical submerged pumps to save floor space, prevent dry running, and suit tailings processing or tank bottom pumping scenarios.
•Conveying Temperature: Slurries >80°C require high‑temperature‑resistant seals and materials to avoid seal failure.
Operation Mode: For continuously running critical systems, “one operating + one standby” is recommended. Shijiazhuang Boda Industrial Pump supports batch matching to avoid production stoppage due to single pump failure. For intermittent operation, standby solutions can be customized as needed.
•Outlet Pressure: When connecting to cyclones, filter presses and other equipment, reserve sufficient outlet pressure and use pumps with steep performance curves. If necessary, multi‑pump series connection technical support can be provided to ensure stable pressure.
