What are reciprocating pumps and how are they used?
How do reciprocating pumps differ from centrifugal pumps?
The main difference is that reciprocating pumps are positive displacement pumps, meaning that they move a specific volume of fluid with each stroke of the piston or plunger. Centrifugal pumps, on the other hand, use a rotating impeller to create a high-velocity flow of fluid in order to move it through the system.
