What is a common characteristic of rubber lined pumps?

Used for high viscosity fluids
Handled with care
Used with slurries containing small particles
Not suitable for temperature extremes

The correct answer is: Used with slurries containing small particles

Rubber lined pumps are commonly used with slurries containing small particles due to their unique design and material composition. The rubber lining provides a level of flexibility and resistance that helps protect the pump components from wear caused by abrasive materials found in slurries. This feature allows the pump to handle the mixed solids and liquids more effectively than traditional metal pumps, which might suffer from erosion and damage when contacting abrasive particles. Additionally, the rubber lining also offers excellent corrosion resistance, making these pumps suitable for transferring a variety of chemically aggressive slurries. The ability to manage the abrasive nature of slurries is a defining characteristic that makes rubber lined pumps preferable in settings where such materials are common. Understanding this characteristic helps in selecting the right pump for specific industrial applications involving slurries.
