Sand and grit contribute to sewer stoppages and cause what on pumps and other plant equipment?

• A. Wear
• B. Tear
• C. Wear/Tear
• D. Corrosion

Answer: (C)

Abrasive sand and grit cause mechanical wear on pumps and other plant equipment. When these hard particles slide or strike against impeller surfaces, bearings, seals, and housing, they grind away metal over time. That repeated material removal and surface damage adds up to wear, and the progressive deterioration of components is what we mean by wear and tear. This damage can reduce pump efficiency, increase vibrations, cause leaks or seal failures, and ultimately lead to stoppages. Corrosion, while a concern in some environments, is a chemical degradation process, not the primary effect of abrasive solids like sand and grit in this context. So wear and tear best describe the impact.
