5. What is pump
Pump is a device that raises,
transfers, delivers, or compresses
fluids or that attenuates gases
especially by suction or pressure
or both.
7. Dynamic pumps
A dynamic pump is a type of pump
that uses mechanical energy to
increase the fluid’s velocity and
convert it into pressure energy.
8. Positive displacement
A positive displacement pump is a type
of pump that moves fluid by trapping a
fixed amount of fluid in a chamber and
then displacing it, providing a constant
flow rate regardless of pressure
change.
