________ pumps are useful for pumping viscous liquids or slurries, but highly viscous liquids would require relatively large, slow moving pumps to keep N.P.S.H.A greater than N.P.S.H.R.

________ pumps are useful for pumping viscous liquids or slurries, but highly viscous liquids would require relatively large, slow moving pumps to keep N.P.S.H.A greater than N.P.S.H.R. Correct Answer Gear

Gear pumps are positive displacement, meaning they pump a const. amount of fluid for each revolution. Some gear pumps are manufactured to function as either a motor or a pump.
