Types of pumps include centrifugal, reciprocating, and rotary pumps.

• Centrifugal pumps use a rotating impeller to increase the pressure of a fluid.

• Reciprocating pumps use a piston or diaphragm to move fluid through a system.

• Rotary pumps use rotating mechanisms to displace fluid, such as gear pumps or vane pumps.

Valves are devices used to control the flow of fluids in a system. Different types include gate, globe, ball, butterfly, and check valves.

• Gate valves are used for on/off control in pipelines.

• Globe valves are used for regulating flow.

• Ball valves are quick to open and close, commonly used in gas pipelines.

• Butterfly valves are lightweight and used for large flow applications.

• Check valves prevent backflow in a system.
