Sandvik Mining and Rock Technology Interview Questions, Process, and Tips

Positive displacement pumps move fluid by trapping a fixed amount and forcing it through the discharge pipe. Negative displacement pumps move fluid by creating a vacuum to draw in and push out the fluid.

• Positive displacement pumps trap a fixed amount of fluid and force it through the discharge pipe

• Examples include gear pumps, piston pumps, and diaphragm pumps

• Negative displacement pumps create a vacuum to draw in and pu...read more
