Do pumps create pressure or flow?

When the liquid slows down in the pump casing, some of the kinetic energy is converted to pressure energy. It is the resistance to the pump’s flow that is read on a pressure gauge attached to the discharge line. A pump does not create pressure, it only creates flow. Pressure is a measurement of the resistance to flow.

What is the difference between an actuator and a solenoid?

The biggest difference between electric and pneumatic actuators is the driving force of their operation. Pneumatic actuators require an air supply of 60 to 125 PSI. The solenoid (pilot) valve is controlled by either an AC or DC voltage. When no air supply is available, electric actuators are used.
