Correct answer to question 6001
- C: A roller pump, because abrasive particles wear the rollers and housing
Explanation
Roller pumps rely on close tolerances between rollers and housing, so abrasive suspensions wear them out fast. Centrifugal, piston, and diaphragm pumps tolerate abrasive products much better.
